Special Issue Information

Dear Colleagues,

Vascular interventions are minimally invasive procedures that are used to treat various vascular conditions, such as blocked or narrowed blood vessels. These techniques involve using catheters and other specialized tools to access and treat the affected area.

The key techniques used in vascular interventions include angioplasty, stenting, atherectomy, thrombectomy and embolization. Angioplasty involves inserting a balloon-tipped catheter into the blocked vessel and inflating it to widen the vessel and improve blood flow. Stenting involves placing a small metal mesh tube (stent) in the vessel to keep it open and prevent it from closing up again. Atherectomy or intravascular lithoplasty is a technique where a catheter is used to remove or break an atheromatous plaque in order to obtain a better angioplasty result. Thrombectomy is a technique that is used to de-clot acutely thrombosed blood vessels. Embolization is used to block off blood flow to a specific area, such as a tumor, by injecting tiny particles, coils or special glue into the blood vessel.

Overall, vascular interventions offer a less invasive alternative to traditional open surgery for treating vascular conditions. These procedures are typically performed by interventional radiologists or vascular surgeons in a specialized vascular lab or operating room. The success and effectiveness of these interventions depend on the specific condition being treated and the skill of the healthcare provider performing the procedure.

Topics of interest for this Special Issue include, but are not limited to, the following:

  • Endovascular therapy for peripheral artery disease;
  • Minimally invasive techniques for treating varicose veins;
  • Interventional radiology in vascular conditions;
  • Vascular stenting and balloon angioplasty;
  • Novel technologies in vascular interventions;
  • Complications and management of vascular interventions.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Bioengineering is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2700 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Objectives: The aim of this study was to investigate the feasibility of contrast-enhanced ultrasound (CEUS)-guided microwave ablation for managing iatrogenic hepatic hemorrhage following percutaneous liver puncture. Materials and methods: This retrospective study analyzed six patients (5 males, 1 female; mean age 56.8 ± 12.3 years) with CEUS-confirmed active hepatic hemorrhage refractory to 10 min compression and Agkistrodon halflorum hemagglutinase administration after percutaneous liver puncture (2023–2024). Etiologies included portal vein cavernous transformation (n = 4) and therapeutic intervention complications (n = 2). All patients underwent CEUS-guided microwave ablation comprising three phases: bleeding site localization, real-time ultrasound-guided ablation, and immediate postprocedural verification (CEUS: n = 6; DSA: n = 2). The protocol was approved by the institutional ethics committee with written informed consent. Results: All six patients achieved immediate hemostasis (mean 2.8 min) through CEUS-guided microwave ablation with 100% technical/clinical success. Preprocedural localization combined color Doppler and CEUS, while intraoperative real-time guidance ensured precise microwave needle placement. Post-ablation verification relied on CEUS (n = 6) with DSA confirmation in two cases. No major complications occurred; one patient reported transient abdominal pain resolving spontaneously. All patients remained stable during 7-day follow-up with no delayed complications. Conclusions: This study suggests that CEUS-guided microwave ablation is a rapid, minimally invasive, and effective option for iatrogenic hepatic hemorrhage, warranting further validation in larger cohorts.
