Klippel-Trenaunay syndrome is a rare congenital anomaly that is associated with abnormalities in the deep venous system. Operative intervention is often used only when patients fail conservative management for chronic venous insufficiency. We present a case of a deep venous abnormality requiring a saphenous vein crossover Palma procedure, in combination with a left femoral arteriovenous PTFE fistula to manage a non-healing wound from chronic venous insufficiency in a 22-year-old man.

A 28-year-old male with history of vascular Ehlers-Danlos syndrome (VEDS) presented with left lower extremity acute limb ischemia. Computed tomography angiography demonstrated spontaneous dissection of the left common iliac artery with occlusion and associated contained rupture . Successful stent placement without associated complications was achieved with the following principles: (1) open arterial exposure for endovascular intervention; (2) no touch technique vessel dissection; (3) circumferential proximal arterial felt cuff reinforcement to reduce systolic pulse wave stretch on sutures, and in case of emergent ligation; and (4) pledgetted "preclose U" stitch monofilament suture prior to access.

Unlabelled: Aortic graft infections are a rare but devastating complication of aortic revascularization. Often infections occur due to contamination at the time of surgery. Iatrogenic misplacement of the limbs of an aortobifemoral graft is exceedingly rare, and principles of evaluation and treatment are not well defined.

Infection of an aortic endograft is a rare complication following endovascular aneurysm repair. These patients have been treated with explantation of the graft to obtain source control followed by an extra-anatomic bypass to restore circulation. The present case study describes an interesting case of Pasteurella infection involving an aortic endograft managed nonoperatively by percutaneous drainage and graft preservation.

Numerous case reports have highlighted the relationship between bacillus Calmette-Guérin (BCG) therapy and development of systemic mycotic aneurysms but none have established a management algorithm in patients with suspected vascular dissemination of Mycobacterium bovis. Delay in diagnosis of this disease process will lead to delays in initiation of antimycobacterium treatment to prevent dissemination into other arterial beds and potentially complicate effective surgical treatment leading to aneurysmal rupture and other devastating vascular consequences. Given the increasing number of reported cases in the literature and the ongoing, standard of care utilization of BCG for bladder cancer, we believe that a systematic approach to the management of patients with suspected BCG-related mycotic aneurysms should be set in place to prevent misdiagnosis and delays in treatment.

Importance: To reduce the amount of skin surface bacteria for patients undergoing elective surgery, selective health care facilities have instituted a preadmission antiseptic skin cleansing protocol using chlorhexidine gluconate. A Cochrane Collaborative review suggests that existing data do not justify preoperative skin cleansing as a strategy to reduce surgical site infection.

Objectives: To develop and evaluate the efficacy of a standardized preadmission showering protocol that optimizes skin surface concentrations of chlorhexidine gluconate and to compare the findings with the design and methods of published studies on preoperative skin preparation.

Renal ectopia in the rare condition of associated abdominal aortic aneurysm presents a difficult clinical challenge with respect to access to the aorto-iliac segment and preservation of renal function because of its anomalous renal arterial anatomy and inevitable renal ischemia at the time of open repair. Multiple operative techniques are described throughout the literature to cope with both problems. We report a case of a 57-year-old male with an aorto-iliac aneurysm and a congenital solitary pelvic kidney successfully treated by hybrid total renal revascularization using iliorenal bypass followed by unilateral internal iliac artery coil embolization and conventional endovascular aortic aneurysm repair without any clinical evidence of renal impairment.

The use of race in biomedical research has, for decades, been a source of social controversy. However, recent events, such as the adoption of racially targeted pharmaceuticals, have raised the profile of the race issue. In addition, we are entering an era in which genomic research is increasingly focused on the nature and extent of human genetic variation, often examined by population, which leads to heightened potential for misunderstandings or misuse of terms concerning genetic variation and race.
