Early pseudoaneurysm degeneration in biologic extracellular matrix patch for carotid repair.

A newly-approved carotid patch, derived from porcine small intestinal submucosa (SIS), is thought to allow functional tissue regeneration by acting as a biologic scaffold of extracellular matrix. We report three cases of asymptomatic pseudoaneurysm after SIS patch closure. At exploration there were intact suture lines, no growth from cultures, and central patch herniation.

Benefit of a single dose of preoperative antibiotic on surgical site infection in varicose vein surgery.

Background: Ligation and division of the saphenofemoral junction (L/D SFJ) can protect against the danger of venous thromboembolism (VTE) associated with greater saphenous vein (GSV) radiofrequency ablation (RFA). Although this procedure is regarded as clean from an infection standpoint, surgical site infection (SSI) can offset its thromboembolic benefit. We questioned whether SSI associated with L/D SFJ could be minimized by a single preoperative dose of antibiotic.
