Abstract
Background: Patients with no-option chronic limb-threatening ischemia (NoCLTI), lacking suitable distal arteries for conventional revascularization, face major limb amputation. The 1-year mortality rate after major amputation is 48.3%, increasing to 70.9% in 3 years. Open deep venous arterialization (DVA) offers a promising alternative [...] Read more.
Background: Patients with no-option chronic limb-threatening ischemia (NoCLTI), lacking suitable distal arteries for conventional revascularization, face major limb amputation. The 1-year mortality rate after major amputation is 48.3%, increasing to 70.9% in 3 years. Open deep venous arterialization (DVA) offers a promising alternative for limb salvage, achievable through open, endovascular, or hybrid approaches. We aim to provide a comprehensive, step-by-step guide to performing open DVA in NoCLTI patients, addressing preoperative and postoperative considerations as well as the technical details of the procedure. Methods: Patient selection for open DVA focuses on individuals with NoCLTI at high risk for amputation. Preoperative assessments include evaluating risk factors, determining limb threat severity using the Wound, Ischemia, and foot Infection (WIfI) score, and mapping anatomical patterns via the Global Limb Anatomic Staging System (GLASS). The procedure involves identifying the target artery using Doppler ultrasound, performing microdissection to expose the artery and vein, ligating proximal vein branches, and creating a side-to-side anastomosis. Venous valves are disrupted with a valvulotome to allow antegrade flow. A proximal bypass graft may be applied if necessary. Results: Postoperatively, patients are monitored for 2–4 days with frequent Doppler assessments. Anticoagulation therapy begins with a heparin drip, transitioning to oral agents and/or dual antiplatelet therapy. Wound care includes deferred debridement for 2–4 weeks and may involve negative-pressure therapy. Follow-up involves weekly visits for the first month, and then at 3 months, and every 6 months thereafter, with surveillance using transcutaneous oxygen measurement, the toe–brachial index, and arterial duplex ultrasound. Conclusions: Open DVA represents a viable limb salvage option for patients with NoCLTI, potentially avoiding major amputations and improving quality of life. Success depends on careful patient selection, a meticulous surgical technique, and comprehensive postoperative care. Full article

Introduction: Single-port video-assisted techniques, such as one-trocar-assisted pyeloplasty (OTAP) or Round-Traction-Assisted Pyeloplasty (RoTAP), have proven helpful for correcting congenital ureteropelvic junction obstruction (UPJO), especially in infants. Surgical Technique: This manuscript presents a technical variation based on the gloveport system that allows bimanual endocavitary dissection and protects the surgical wound during the procedure without increasing the cost or technical difficulty. Comment: This new technique, called gloveport-assisted retroperitoneal pyeloplasty (GARP), could be a valuable alternative for this pathology. Full article

Cytoreductive surgery in the context of a multidisciplinary approach, including adjuvant and neoadjuvant therapy (when indicated), aims ideally to obtain complete resection and represents the cornerstone for long-term survival in patients with advanced ovarian cancer (AOC). Positive lymph nodes are a relatively frequent appearance during cytoreductive surgery for AOC and a widely accepted negative prognostic factor for long-term survival. However, the impact of systematic pelvic and paraaortic lymph node dissection (SPALND) on early and long-term outcomes in patients with cytoreductive surgery for AOC and no suspected positive lymph nodes remains highly controversial. The paper aims to review the relevant scientific literature exploring the role of SPALND in patients with AOC, focusing on peer-reviewed papers published before and after the LION study’s data release. The LION trial represents the only level 1 evidence study providing no scientific arguments for the routine using SPALND in AOC as part of complete cytoreductive surgery in patients without clinical suspicion of positive lymph nodes. The LION trial changed the practice of surgeons regarding SPALND, and current essential guidelines do not recommend it as a routine. Furthermore, SPALND may increase morbidity rates of cytoreductive surgery for AOC and negatively impact the patient’s quality of life. A comprehensive pelvic and paraaortic lymph node assessment is mandatory before and during cytoreductive surgery for AOC for proper disease staging, adequate management, and long-term prognosis. Further research is needed to identify patients with AOC at high risk for lymph node metastases; this group might benefit from SPALND. Full article

Background: Bronchial sleeve resection with complex reconstruction is a rare and intricate surgical procedure, particularly when addressing metastatic carcinoid tumors. This case report details the surgical management of a young male with a typical carcinoid tumor metastasized to the hilar and subcarinal lymph nodes. Case Presentation: A 28-year-old medically fit male presented with cough and occasional blood-tinged sputum for 2 months that was diagnosed to be due to a typical carcinoid tumor involving the left main bronchus, with metastasis to the hilar and subcarinal lymph nodes. The patient underwent a left bronchial sleeve resection with complex reconstruction of the left lower lobe bronchus. The reconstructed bronchus was then anastomosed to the main bronchus followed by hilar and subcarinal lymph nodes dissection. The surgical approach aimed to preserve lung parenchyma while ensuring complete tumor resection. Postoperative recovery was uneventful, with the patient demonstrating satisfactory respiratory function. Histopathological examination confirmed the complete resection of the carcinoid tumor and metastatic lymph nodes (hilar and inter-lobar LN (positive 2/5) and subcarinal LN (positive 1/6)). The patient had no signs of recurrence at the 3-month follow-up. Conclusions: This case highlights the feasibility and effectiveness of bronchial sleeve resection with bronchial reconstruction in managing metastatic carcinoid tumors. The successful outcome underscores the importance of meticulous surgical planning and execution in achieving favorable results in complex thoracic surgeries. Full article

Background/Objectives: Popliteal artery injury is a rare but devastating complication of knee dislocations, significantly increasing the risk of limb ischemia, amputation, and poor functional outcomes if not promptly managed. This systematic review primarily evaluates the functional outcomes associated with this injury but also reviews current research on diagnostic modalities and treatment strategies to provide a comprehensive understanding of this severe orthopedic and vascular injury. Methods: A systematic search of PubMed, in accordance with PRISMA Guidelines, identified 144 studies, of which 13 full-text articles were assessed for eligibility after excluding 131 during the title and abstract screening. Six studies were excluded due to missing vascular injury or functional outcome data or being written in a foreign language, leaving seven studies for inclusion. These studies were predominantly retrospective, focusing on knee dislocations with popliteal artery injury and reporting validated functional outcomes such as the Lysholm and International Knee Documentation Committee (IKDC) scores. The data were synthesized narratively due to heterogeneity in the study designs, interventions, and outcome reporting. Results: Patients with vascular injuries consistently demonstrated poorer functional outcomes compared to those without, with mean or median Lysholm and IKDC scores consistently being lower than non-vascular injury patients. Increased BMI, delayed intervention, and multi-ligamentous injury were associated with worse outcomes, highlighting the importance of timely surgical management. Early repair and grafting techniques improved functional recovery, while diagnostic modalities such as Doppler ultrasound and CT angiography showed high sensitivity in detecting vascular injury. Complications included limb ischemia, prolonged rehabilitation, and amputation, often linked to delayed diagnosis. Conclusions: Knee dislocations with popliteal artery injury require rapid diagnosis and early surgical intervention to optimize functional outcomes and reduce complications. Standardized outcome measures and high-quality prospective research are needed to refine management strategies and address patient-specific factors like BMI. Full article

Background: Anterior cervical discectomy and fusion (ACDF) is a common procedure for cervical radiculopathy and myelopathy. Severe obesity (BMI ≥ 40 or BMI ≥ 35 with comorbidities) is associated with increased perioperative risks. This study examines the impact of severe obesity on outcomes in patients undergoing single-level ACDF. Methods: Data from the Nationwide Inpatient Sample (2016–2019) were analyzed, including 85,585 patients who underwent single-level ACDF. Patients were classified as severely obese (n = 4935) or non-obese (n = 80,650). Outcomes such as length of stay, complications, and in-hospital mortality were compared using SPSS and MATLAB, with a significance level of p < 0.05. Results: Severely obese patients were younger (54 vs. 55.7 years, p < 0.001) and had more comorbidities like type 2 diabetes (38% vs. 17.8%, p < 0.001) and obstructive sleep apnea (31.1% vs. 9.5%, p < 0.001). They experienced longer hospital stays (1.92 vs. 1.65 days, p < 0.001) but similar in-hospital mortality (0.1%, p = 0.506). Severe obesity was linked to higher odds of complications, including increased risks of dehiscence (OR 8.2), respiratory failure (OR 6.5), myocardial infarction (OR 5.5), Horner syndrome (OR 4.7), pulmonary edema (OR 4.5), and dural tears (OR 4.1). Risks of acute kidney injury, pulmonary embolism, and dysphonia were also elevated in severely obese patients. Conclusion: Severe obesity is associated with higher complication rates and longer hospital stays following ACDF. Tailored perioperative management is essential to mitigate these risks and improve outcomes in this high-risk population. Full article
