Distal arteriovenous fistula to preserve patency in COVID-19-associated acute limb ischemia.

The purpose of this study was to report our institutional experience with patients with COVID-19 who developed acute limb ischemia during hospitalization and to determine the characteristics and clinical outcomes. Between March 2020 and January 2021, we treated 3 patients who were COVID-19-positive and developed acute limb ischemia after they received thromboprophylaxis. We performed an embolectomy by exposing the popliteal artery below the knee to treat an occlusion of the popliteal and tibial arteries.

Heparin-bonded expanded polytetrafluoroethylene grafts for infragenicular bypass in patients with critical limb ischemia: 2-year results.

Aim: The use of prosthetic grafts in below-knee (BK) bypasses may be necessary in patients with no available autologous vein and critical limb ischemia not amenable to angioplasty. Such conduits, however, have generally yielded disappointing results.

Methods: A new heparin-bonded expanded polytetrafluoroethylene graft (Gore-Tex Propaten Vascular Graft) designed to provide resistance to thrombosis may be associated with decreased early graft failure and increased patency.

[Inflammatory pseudotumour of the spleen: a case report and review of the literature].

The case of a 64-year-old man presenting dysuria and haematuria is described. The cause of these symptoms was related to a splenomegaly compressing the left kidney and renal pelvis. A splenectomy was performed.

[Verneuil's disease or perianal hydradenitis suppurativa].

Verneuil's disease or perianal hidradenitis suppurativa is a chronic suppurative disease with a tendency to fistulization and sclerosis, developing on the subcutaneous tissue, on apocrine glands. The perianal location is the most frequent, and the elective therapy in such case is surgery. A case of perianal Verneuil's disease of great size, invalidating for the patient, in which medical therapy failed, making necessary an aggressive surgical treatment is reported.
