Spinal cord ischemia (SCI) remains a significant concern in patients undergoing endovascular repair involving the thoracic aorta (thoracic endovascular aortic repair [TEVAR]). Perioperative lumbar spinal drainage has been widely practiced for open repair, but there is no consensus treatment protocol using lumbar drainage for SCI associated with TEVAR. This study analyzes the efficacy of an institutional protocol using selective lumbar drainage reserved for patients experiencing SCI following TEVAR. ⋯ A protocol utilizing selective postoperative lumbar spinal drainage can be used safely for patients developing SCI after TEVAR with acceptably low permanent neurologic deficit, although overall survival of patients experiencing SCI after TEVAR is diminished relative to non-SCI patients.

Increased utilization of computed tomography angiography (CTA) has increased the radiologic diagnosis of penetrating atherosclerotic ulcers (PAUs), which are defined as the ulceration of atherosclerotic plaque through the internal elastic lamina into the aortic media. However, the presentation, treatment indications, and natural history of this disease process remain unclear. ⋯ For PAUs diagnosed on CTA at a single institution, 4.1% were ruptured and 12.9% underwent repair. Close follow-up imaging appears to be indicated for PAUs, particularly in the case of symptomatic disease, which is more likely to require repair and to undergo radiographic progression.

This study was conducted to define bandage pressures that are safe and effective in treating leg ulcers of mixed arterial-venous etiology. ⋯ In patients with mixed ulceration, an ankle-brachial pressure index >0.5 and an absolute ankle pressure of >60 mm Hg, inelastic compression of up to 40 mm Hg does not impede arterial perfusion but may lead to a normalization of the highly reduced venous pumping function. Such bandages are therefore recommended in combination with walking exercises as the basic conservative management for patients with mixed leg ulcers.

Diabetes is prevalent in most patients undergoing carotid revascularization and is suggested as a marker of poor outcome after carotid endarterectomy (CEA). Data on outcome of diabetic patients undergoing carotid artery stenting (CAS) are limited. The aim of this study was to investigate early and 6-year outcomes of diabetic patients undergoing carotid revascularization with CAS and CEA. ⋯ Diabetic patients are not at greater risk of perioperative morbidity and mortality or late stroke after CAS, however, the perioperative risk can be higher after CEA. This may help in selecting the appropriate technique for carotid revascularization in patients best suited for the type of procedure.

The impact of resident surgeon participation during vascular procedures on postoperative outcomes is incompletely understood. We characterized resident physician participation during carotid endarterectomy (CEA) procedures within the 2005-2009 American College of Surgeons National Surgical Quality Improvement Participant Use Datafile and evaluated associations with procedural characteristics and perioperative adverse events. ⋯ Resident surgeon participation during CEA is not associated with risk of adverse perioperative events.
