Purpose: To evaluate the success rates of the implantation of stent grafts in the treatment of peripheral aneurysms.
Materials And Methods: In 13 patients with 15 aneurysms at the common iliac artery (n = 6), external iliac artery (n = 1), hypogastric artery (n = 2), femoral artery (n = 2) or popliteal artery (n = 4), implantation of dacron-covered nitinol stents was performed. The patients were followed up for three to 20 months (mean, 8.8 months) with intravenous digital subtraction angiography, CT or colour-coded Doppler sonography.
Results: In all cases, the aneurysm was successfully occluded after stent implantation. In one case with a popliteal aneurysm, kinking of the vessel caused thrombosis of the stent. The stent was successfully reopened. The aneurysm however, had to be surgically treated 9 months later. The primary and secondary patency rates at 6 months were 93% and 100%, respectively.
Conclusion: The method described might be an alternative therapy to surgery. There are some limitations in respect of treatment of popliteal aneurysms.

Effects of Prophylactic Coil Embolization of Pelvic Arteries on Surgical Outcomes in Hemodynamically Stable Patients with Complex Acetabular Fractures.

Objectives: To investigate the efficacy of prophylactic embolization of the internal iliac artery (IIA) or superior gluteal artery (SGA) before open reduction and internal fixation (ORIF) in reducing intraoperative blood loss (IBL) in hemodynamically stable patients with complex acetabular fractures.
Materials And Methods: A total of 136 patients with complex acetabular fractures were retrospectively included and divided into the prophylactic transcatheter arterial embolization (PTAE) group and non-PTAE group, depending on whether ipsilateral IIA or SGA was embolized using coils within 3 days before ORIF. Demographic characteristics, injury severity score (ISS), fracture classification, and intraoperative and postoperative data were compared between the two groups.
Three types of side-to-side microvascular anastomosis training models using rat abdominal vessels.

Background: Side-to-side microvascular anastomosis is the most difficult type of anastomosis. The best way to master microvascular anastomosis technique is deliberate practice in the microsurgical laboratory.
Methods: Three types of side-to-side microvascular anastomosis using the rat abdominal vessels were presented.
A Belgian physician-initiated trial investigating the LifeStream peripheral stent graft system for the treatment of complex TASC C and D iliac lesions.

Department of Vascular Surgery, AZ Sint Blasius, Dendermonde, Belgium.
Background: Due to the heterogeneity of literature findings, stent type selection for the endovascular treatment of complex aorto-iliac occlusive disease remains challenging. The BELSTREAM study, a physician-initiated, prospective, multicenter, single-arm study, aims to report the safety and efficacy of the balloon expandable LifeStream Peripheral Stent Graft System (BD, Tempe, Arizona, USA) for the treatment of complex TASC C and D aorto-iliac artery lesions.
Methods: Seventy patients and 133 lesions were included at six Belgian institutions.
Antithrombotic therapy following lower extremity endovascular revascularization: The results of a survey of vascular specialists.

Division of Vascular Surgery, University of Pittsburgh.
Objective: Antithrombotic therapy improves endovascular intervention outcomes for peripheral artery disease. However, there are limited data guiding the choice and duration of these adjuvant therapies. Thus, we explored current antithrombotic prescribing preferences among vascular interventionalists, hypothesizing that there are varied and inconsistent treatment practices among providers.

Although the deep circumflex iliac artery (DCIA) flap is a mainstay in mandibular reconstruction, its multi-segmental utilization is infrequently reported, primarily due to concerns regarding the variable cutaneous component and potentially inadequate vascular supply to multi-block segments. This retrospective study analyzed the outcomes of 86 patients undergoing mandibular reconstruction with multi-segmental DCIA flaps, compared to 167 patients who received conventional single-segmental flaps. The survival rate for multi-segmental flaps was comparable to that of single-segmental flaps (100% vs.
