Impact of chronic kidney disease on the outcomes of infrapopliteal venous, and heparin-bonded expanded polytetrafluoroethylene bypass surgeries: A retrospective cohort study.

The aim of this study was to analyze the results of infrapopliteal venous and prosthetic bypass surgeries for patients with chronic limb-threatening ischemia (CLTI) and moderate to severe chronic kidney disease (CKD). All consecutive patients undergoing infrapopliteal bypass surgeries at two academic vascular centers between March 2002 and November 2018 were included in this retrospective study. During this timeframe, infrapopliteal grafts were performed for 487 patients.

Midterm outcome of biosynthetic collagen prosthesis for treating aortic and peripheral prosthetic graft infections.

Objectives: To report the midterm outcomes of treating prosthetic peripheral and aortic graft infections using a biosynthetic collagen prosthesis in a tertiary vascular center.

Methods: A retrospective analysis of all patients with prosthetic peripheral and aortic graft infections who underwent in situ reconstruction using a biosynthetic collagen prosthesis between March 2015 and November 2020 was conducted. Perioperative and midterm outcomes were analyzed.

Role of aorto(bi)femoral bypass in treatment of patients with critical limb threatening ischemia.

Purpose: To analyse the long-term outcome of open aortic procedures in patients with critical limb threatening ischemia.

Methods: Retrospective analysis of all patients with aortoiliac TransAtlantic Inter-Society Consensus II (TASC II), type D (TASC D) lesions extending to the femoral artery who underwent aortic bypass procedures for critical limb threatening ischemia (CLTI) or intermittent claudication (IC).

Results: Over a period of 10 years, 87 patients with IC and 45 patients with CLTI received a total of 56 aortounifemoral and 76 aorto-bi-femoral bypass procedures.

Necrosis of the leg after intraarterial drug injection.

Inadvertent intraarterial injections in the context of drug abuse can cause damage to the vascular system. The clinical picture depends on the drug properties and ranges from partial ischemia to necrosis of the affected extremity. There are no current evidence-based guidelines regarding the management of intraarterial drug injections.
