Background: Venous thromboembolism (VTE) is conventionally treated with anticoagulant therapy. In contrast, the core treatment for peripheral artery disease (PAD) is antiplatelet therapy. VTE and PAD share common risk factors and may occur in the same patient. Nonetheless, there is little evidence of the best antithrombotic regimen to use when the two conditions coexist, especially in terms of the extended prevention of major adverse cardiovascular events (MACE), major adverse limb events (MALE), and VTE recurrences. Methods: We conducted an online survey of members of the Italian Society of Angiology and Vascular Medicine (SIAPAV) to explore current prescribing habits for extended antithrombotic therapy in patients with PAD and unprovoked VTE. The survey included four clinical scenarios with variations in age, gender, bleeding risk, index VTE event, and severity of PAD. In all cases, patients had received anticoagulation for 6 months, and the key question was how to continue treatment beyond 6 months from the index VTE event. Results: A total of 174 clinicians participated to the survey. The most common choice was combining antiplatelet therapy with a direct oral anticoagulant (DOAC) at a low dose. Full-dose DOAC alone or antiplatelet therapy alone were less frequently chosen. Older age and high bleeding risk increased the preference for antiplatelet therapy alone. Conclusions: This survey highlights the marked variability in antithrombotic prescribing patterns among specialists in vascular medicine for patients with unprovoked VTE and concomitant PAD, reflecting the lack of evidence on optimal management in this specific setting. More research is needed to define the safest and most effective treatment strategies for patients with concurrent PAD and VTE. Full article

(1) Background: Maternal venous hemodynamic dysfunction is an intrinsic part of the pathophysiology of pre-eclampsia and fetal growth restriction. The aim of this study is to evaluate whether venous hemodynamic dysfunction is present in women with a history of (unexplained) recurrent miscarriage, and to link this pilot observation to reported data in the literature. (2) Methods: A retrospective search of hospital records was conducted to find data on recurrent miscarriage and hemodynamics assessment prior to conception. We also performed a scoping search of the literature regarding the association between recurrent miscarriage and maternal hemodynamics, reproductive outcomes, maternal complications, neonatal complications, and long-term cardiovascular function in women and their offspring. (3) Results: Six out of nine women with a history of recurrent miscarriage had preconception venous hemodynamic dysfunction. This observation is in line with the reported data on reduced venous reserves in association with low plasma volume in women with recurrent miscarriage, and adds to the reported link between recurrent miscarriage, poor reproductive outcomes, and chronic cardiovascular disease. (4) Discussion: This retrospective observational cohort supports an association between venous hemodynamic dysfunction and recurrent miscarriage that is corroborated by data reported in the literature. Abnormal venous hemodynamic function can be improved before conception, and this opens a new and currently unexplored pathway in the management of recurrent miscarriage. Full article

Background: Pancreatoduodenectomy with venous resection (PDVR) may be performed to achieve tumour clearance in patients with a pancreatic ductal adenocarcinoma (PDAC) with venous involvement. This study aimed to evaluate the impact of PDVR on PDAC outcomes. Methods: In total, 435 PDAC patients with either R0 status (n = 322) or R1 status within the superior mesenteric vein groove (n = 113) were extracted from the Recurrence After Whipple’s (RAW) study dataset. PDVR patients were matched in a 1:2 ratio with standard PD patients. Comparisons were then made between the two groups (surgical radicality and survival). Results: A total of 81 PDVRs were matched with 162 PDs. Neoadjuvant chemotherapy (5.7% vs. 13.6%, p = 0.032) and R1 resection rates (17.9% vs. 42%, p < 0.001) were higher in the PDVR group. Risk factors for R1 resection included venous resection (p < 0.001 for sleeve and p = 0.034 for segmental resection), pT3 (p = 0.007), and pN1 stage (p = 0.045). PDVR patients had lower median overall survival (OS, 21 vs. 30 months (m), p = 0.023) and disease-free survival (DFS, 17 m vs. 24 m, p = 0.043). Among PDVR patients, R status did not impact on OS (R0: 23 m, R1: 21 m, p = 0.928) or DFS (R0: 18 m, R1: 17 m, p = 0.558). Irrespective of R status, systemic recurrence was higher in the PDVR group (p = 0.034). Conclusions: Independent of R status, the PDVR group had lower overall survival and higher systemic recurrence rates. Full article

Background: Transanal endoscopic microsurgery (TEMS) is an organ-preserving approach for treatment of early rectal cancer (ERC). However, adverse histopathological features identified post-TEMS often necessitate adjuvant therapy. This study aims to compare the long-term oncological outcomes of patients who underwent TEMS and were offered adjuvant treatments with total mesorectal excision (TME), chemoradiotherapy (CRT), radiotherapy (RT), active surveillance, or dose escalation with contact X-ray brachytherapy (CXB). Methods: This study included patients treated with TEMS for ERC between September 2012 and December 2022, with follow-up until December 2023. Patients with adverse histopathological features (extra-mural venous invasion, lympho-vascular invasion, R1 margins, tumour budding) were assigned to adjuvant treatments. Inverse probability of treatment weighting (IPTW) was applied to mitigate selection bias. Results: Of the 117 patients, 24 underwent TME, 17 received CRT, 25 received RT, 14 underwent active surveillance, and 37 patients received CXB boost along with CRT. The median follow-up was 60 months (IQR 52–73). During this time, 29 patients developed recurrence, and 15 died. The 5-year overall survival (OS) was 78.6%, and disease-free survival (DFS) was 70.9%. Compared to CXB, the mortality risk for CRT (HR = 0.81; 95% CI: 0.20–3.28; p = 0.77) and TME (HR = 3.68; 95% CI: 0.46–29.79; p = 0.22) was not significantly different. However, TME was associated with a significantly higher recurrence risk compared to CXB (HR = 7.57; 95% CI: 1.23–46.84; p = 0.029). Conclusions: An organ-preserving strategy with CRT or CRT combined with a CXB boost may offer comparable long-term outcomes and reduced recurrence risks for patients undergoing TEMS for ERC with poor prognostic features. Further research with larger cohorts is needed to validate these results. Full article

Introduction: Meningeal metastasis (MM) from naso-ethmoidal malignancies (NEMs) is rare, its metastatic route is still debated, and its prognostic impact remains unclear. Our aim is to analyze a retrospective series of NEMs with non-contiguous MM to study the possible route of spread and the prognostic value of MM. Materials and methods: The institutional database of SNC treated at the University of Brescia between 1995 and 2021 was reviewed. Clinical–pathological data were collected, and survivals were estimated with Kaplan–Meier. Univariate and multivariate logistic regression analysis were run to identify predictors of MM. Results: Among 296 patients, 17 experienced non-contiguous MM, all located along the dura. Intestinal-type adenocarcinoma (10/17) and olfactory neuroblastoma (3/17) were the most frequent histologies. At univariate analysis, brain edema (p < 0.0001), resection (p = 0.026) or invasion (p = 0.006) of brain parenchyma, and local (p = 0.0004) and nodal (p = 0.021) recurrence were predictors of MM. At multivariate analysis, local recurrence was confirmed as an independent factor (odds ratio: 11.88, p = 0.0005). Dural surgical resection was not a risk factor. The five-year disease-specific survival was longer in patients with exclusive MM compared with patients with distant metastasis at other sites (64.3% vs. 30.1% p = 0.046). Conclusions: Dural venous shunt is the most likely pathway of spread of MM. Local recurrence is the only independent risk factor. Exclusive MM has a better prognosis than extrameningeal metastasis.

Branch retinal vein occlusion (BRVO) is a common retinal vascular condition and a significant contributor to vision loss worldwide, particularly in middle-aged and elderly populations. This review synthesizes current knowledge on the epidemiology, pathogenesis, and clinical features of BRVO, alongside recent advancements in diagnostic and therapeutic strategies. BRVO is approximately four times more prevalent than central retinal vein occlusion (CRVO) and often leads to significant vision impairment. By focusing on BRVO, this review aims to address the specific challenges and advancements in its diagnosis and management. The pathophysiology of BRVO is complex, involving factors such as venous compression, inflammation, and increased levels of vascular endothelial growth factor (VEGF). Diagnostic approaches such as optical coherence tomography (OCT) and fluorescein angiography are highlighted for their roles in assessing disease severity and guiding treatment decisions. Therapeutic interventions, including laser photocoagulation, anti-VEGF therapy, and intravitreal corticosteroids, are critically evaluated, emphasizing emerging treatments such as gene therapy, peptide-based agents, and small-molecule inhibitors. Despite advancements in management strategies, the recurrence of macular edema and treatment resistance remain significant challenges. Continued research is essential to refine therapeutic protocols and improve long-term visual outcomes for patients with BRVO. Full article

Antiphospholipid syndrome (APS) is a thrombo-inflammatory disease propelled by circulating autoantibodies that recognize cell surface phospholipids and phospholipid-binding proteins. APS is an autoimmune disorder associated with recurrent thrombosis of arterial or venous vessels and/or recurrent obstetric complications as miscarriages. APS can be divided into primary or secondary clinical syndrome because of the possible association with other autoimmune systemic diseases as systemic lupus erythematosus (SLE). Vitamin K antagonists remain the mainstay of treatment for most patients with APS and, based on current data, appear superior to the more targeted direct oral anticoagulants. However, the choice of the type of antithrombotic drug is based on the anamnesis of affected patients: patients with previous arterial or venous thrombosis may benefit from anticoagulants, while patients with previous obstetric diseases may benefit from aspirin, but several clinical exceptions may be evaluated. This short review is dedicated to underlining the main clinical evidence for patients affected by APS or CAPS (catastrophic antiphospholipid syndrome) in order to prevent recurrent thrombosis.

Chronic varicose veins disease is widespread worldwide (up to 60% in the adult population), with a significant impact on patients' quality of life and a high cost to society, both due to treatment and the limitation of physical activity imposed by the disease. This article presents a retrospective study on a number of 14 patients treated in Arestetic Clinic in Galati, for a period of one year. The patients included in the study presented reticular and varicose veins up to 6 mm in diameter and under 14 mm on the saphenous vein. Patients completed the Aberdeen Varicose Disease Questionnaire (excluding the first part of the questionnaire) and the Venous Clinical Severity Score was used by the physician. Doppler ultrasound was used for preoperative evaluation and postoperative monitoring. Polidocanol was administered in concentrations of 0.5% and 2%, with the patients being monitored one year after treatment. All patients were declared satisfied with the results and 1 year after treatment no recurrences were found. Polidocanol sclerotherapy is a safe, easy-to-administer, low-cost treatment with no healing time and can be administered multiple times if needed, with minimal risks of complications. Aesthetic results are good, with an important symptom remission rate and high patient satisfaction. Complications were rare and minor (represented by local hyperpigmentation and hardening of the injected path), and the recurrence rate is comparable to surgical treatment. Full article

Venous thromboembolism (VTE) is a serious health condition and represents an important cause of morbidity and, in some cases, mortality due to the lack of effective treatment options. According to the Centers for Disease Control and Prevention, 3 out of 10 people with VTE will have recurrence of a clotting event within ten years, presenting a significant unmet medical need. For some VTE patients, symptoms can last longer and have a higher than average risk of serious complications; in contrast, others may experience complications arising from insufficient therapies. People with VTE are initially treated with anticoagulants to prevent conditions such as stroke and to reduce the recurrence of VTE. However, thrombolytic therapy is used for people with pulmonary embolism (PE) experiencing low blood pressure or in severe cases of DVT. New drugs are under development, with the aim to ensure they are safe and effective, and may provide an additional option for the treatment of VTE. In this review, we summarize all ongoing trials evaluating anticoagulant interventions in VTE listed in clinicaltrials.gov, clarifying their underlying mechanisms and evaluating whether they prevent the progression of DVT to PE and recurrence of thrombosis. Moreover, this review summarizes the available evidence that supports the use of antiplatelet therapy for VTE. Since thrombolytic agents would cause off-target effects, targeted drug delivery platforms are used to develop various therapeutics for thrombotic diseases. We discuss the recent advances achieved with thrombus-targeting nanocarriers as well as the major challenges associated with the use of nanoparticle-based therapeutics. Full article

Despite the clear indications and worldwide application of specific guidelines, the recognition of Infective Endocarditis (IE) may be challenging in day-to-day clinical practice. Significant changes in the epidemiological and clinical profile of IE have been observed, including variations in the populations at risk and an increased incidence in subjects without at-risk cardiac disease. Emergent at-risk populations for IE particularly include immunocompromised patients with a comorbidity burden (e.g., cancer, diabetes, dialysis), requiring long-term central venous catheters or recurrent healthcare interventions. In addition, healthy subjects, such as skin-contact athletes or those with piercing implants, may be exposed to the transmission of highly virulent bacteria (through the skin or mucous), determining endothelial lesions and subsequent IE, despite the absence of pre-existing at-risk cardiac disease. Emergent at-risk populations and clinical presentation changes may subvert the conventional paradigm of IE toward an unexpected clinical scenario. Owing to its unusual clinical context, IE might be overlooked, resulting in a challenging diagnosis and delayed treatment. This review, supported by a series of clinical cases, analyzed the subtle and deceptive phenotypes subtending the complex syndrome of unexpected IE. The awareness of an unexpected clinical course should alert clinicians to also consider IE diagnosis in patients with atypical features, enhancing vigilance for preventive measures in an emergent at-risk population untargeted by conventional workflows.

Background/Objective: The endovenous embolization of insufficient abdominal/pelvic veins is the preferred method of treatment. Also, it seems to be crucial in the treatment of lower limb vein insufficiency, particularly in recurrent disease. This study aimed to evaluate of pelvic vein embolization safety and its impact on the short-term outcome in the sequential treatment of venous disease. Methods: A retrospective analysis involved data from 506 female patients with venous disease involving abdominal and pelvic veins. All records were extracted from the medical database and included patient history, imaging reports as well as pre- and post-operative surveys. Results: Among the patients analyzed, 37.2% underwent some venous intervention in the past, with significant differences in symptom severity between groups. The embolization procedure revealed a high safety profile, with no serious complications. Pain during and after the procedure was generally low, with significantly lower pain scores in patients with recurrence. In patients who required left renal vein venoplasty a 1.7-fold increased risk of lumbar pain after embolization and venoplasty procedure was observed. Overall, 66.6% of patients reported improvement in pelvic symptoms and 72.1% experienced improvement in leg symptoms. The full sequential treatment protocol (abdominal, pelvic, and leg compartment) demonstrated superior outcomes in leg symptom improvement compared to embolization alone. Conclusions: Pelvic vein embolization is a safe and effective method of treatment, significantly improving both pelvic and leg symptoms, particularly in patients with a history of previous interventions in lower limb veins. Further studies are warranted to validate our findings and further refine treatment protocols. Full article

Background: Renal angiomyolipoma (AML) without local invasion is generally considered benign. However, it may extend to the renal sinus, even the renal vein, or the inferior vena cava (IVC). In patients with non-tuberous sclerosis complex, coexistence of renal cell carcinoma (RCC) and renal AML is uncommon. Case presentation: A 72-year-old woman was incidentally found to have a solitary right renal mass with an IVC thrombus extending into the right atrium during a routine health checkup. Robot-assisted laparoscopic radical nephrectomy and thrombectomy were successfully performed through adequate preoperative examination and preparation. Two tumor lesions were found and pathologically confirmed as renal AML and RCC, and the tumor thrombus was derived from the renal AML. During the one-year follow-up period, no signs of recurrence or metastatic disease were observed. Conclusions: Renal AML with a tumor thrombus in the IVC and right atrium accompanied by RCC may occur, although rarely. In clinical practice, if preoperative manifestations differ from those of common diseases, rare diseases must be considered to avoid missed diagnoses. In addition, adequate examination and multidisciplinary discussions before making a diagnosis are necessary. For a level 4 tumor thrombus with no infringement of the venous wall, adoption of robot-assisted minimally invasive surgery, without extracorporeal circulation technology, is feasible. Full article

Venous thromboembolism (VTE) is the leading cause of morbidity and death worldwide, after cancer and cardiovascular diseases. VTE is defined to include pulmonary embolism (PE) and/or deep vein thrombosis (DVT). Approximately 25% of PE patients experience sudden death as an initial symptom of VTE, and between 10% and 30% of patients die within the first month after diagnosis. Currently, the only drugs approved for the treatment of both acute and chronic VTE are vitamin K antagonists (VKAs) and direct oral anticoagulants (DOACs). However, their effectiveness is limited due to their associated risk of bleeding. Ideally, therapy should be able to treat VTE and limit the risk of VTE recurrence without increasing the risk of bleeding. Several studies have shown that the use of statins during anticoagulation for VTE reduces the risk of death and VTE recurrence. However, to date, there are conflicting data on the impact of statins during anticoagulation for VTE. A biological protective function of statins during anticoagulation has also been reported. Statins affect D-dimer levels; tissue factor (TF) gene expression; and VIII, VII, and Von Willebrand clotting factors—the major clotting factors they are able to affect. However, the usefulness of statins for the treatment and prevention of VTE is currently under debate, and they should not be substituted for guideline-recommended VTE prophylaxis or anticoagulation treatment. In this review of the literature, we illustrate the advances on this topic, including data on the role of statins in primary VTE prevention and secondary VTE prevention, related biological mechanisms, the risk of bleeding during their use, and their ability to reduce the risk of death.

Venous leg ulcers (VLUs) are hard-to-heal wounds and are prone to microbial colonization. Innovative and improved therapies are thus required to resolve local infection and enhance the wound healing process. The objective of this study was to evaluate the effectiveness of medical-grade honey (MGH) for the treatment of clinically infected and non-healing VLUs. This prospective case series included nine patients with an average age of 83.4 years (range: 75–91 years) with a total of eleven VLUs, previously ineffectively treated with various products. Major risk factors for the appearance of VLUs were chronic venous insufficiency, advanced age, multiple comorbidities (particularly cardiovascular diseases), and impaired mobility. All wounds presented with local signs of infection. Upon presentation, treatment was commenced with a range of MGH-based products (L-Mesitran^®). Clinical signs of infection were eliminated by MGH after 2.2 weeks on average (range: 1–4 weeks), and wounds were completely healed after 7 weeks on average (range: 3–18 weeks). No further complications or recurrences were observed. MGH has a broad-spectrum antimicrobial activity and promotes rapid healing, thus improving patients’ quality of life. Moreover, MGH-based products are safe, easy to use, cost-effective, and can effectively treat VLUs alone or in combination with standard-of-care therapies. Full article

Preeclampsia (PE) is a hypertensive disorder in pregnancy associated with significant fetal and maternal complications. Antiphospholipid syndrome (APS) is an acquired form of thrombophilia characterized by recurrent venous or arterial thrombosis and obstetric complications that significantly increases morbidity and mortality rates. While preeclampsia may not be the most prevalent obstetric complication in APS, it significantly impacts the long-term health of both mother and child. The treatment of preeclampsia in antiphospholipid syndrome is different from the treatment of preeclampsia as an independent disease. Despite current treatments involving anticoagulants, antiplatelet agents, and antihypertensive drugs, obstetric complications may persist, underscoring the need for cohesive management and effective treatments. The objective of our review is to briefly present knowledge about the physiopathology of preeclampsia and the role of antiphospholipid antibodies in this process. Based on the existing literature, our review aims to identify future directions in molecular pathology toward the discovery of biomarkers and targeted treatments. The application of multidisciplinary approaches and prognostic models, including new biomarkers, could be beneficial in the prediction of PE. Full article
