Review Case Reports
Hybrid repair of ruptured type B aortic dissection extending into an aberrant right subclavian artery in a patient with Turner's syndrome.
Turner's syndrome (TS) has been documented as the most common cause of aortic dissection in young women. However, little attention from vascular surgery has been paid to these patients. ⋯ Left carotid to subclavian artery bypass, thoracic endovascular aortic repair, and coil embolization of the aberrant right subclavian and left subclavian arteries were performed in an emergency setting. Literature on epidemiology, causes, and management options of acute aortic dissection in TS patients are reviewed and discussed.

Multicenter Study Comparative Study
Comparison of graft patency, limb salvage, and antithrombotic therapy between prosthetic and autogenous below-knee bypass for critical limb ischemia.
The autogenous vein is the preferred conduit in below-knee vascular reconstructions. However, many argue that prosthetic grafts can perform well in crural bypass with adjunctive antithrombotic therapy. We therefore compared outcomes of below-knee prosthetic versus autologous vein bypass grafts for critical limb ischemia and the use of adjunctive antithrombotic therapy in both settings. ⋯ Although limited in size, our study demonstrates that, with appropriate patient selection and antithrombotic therapy, 1-year outcomes for below-knee prosthetic bypass grafting can be comparable to those for greater saphenous vein conduit.

In this report we describe a special method of using a pedicled latissimus dorsi muscle flap for a mycotic aneurysm. The method involves wrapping the flap around a prosthetic graft. Using this method, an in situ graft, which replaces an aneurysm, can help to avoid recurrence of local infection.

Blunt thoracic aortic injury (BTAI) is associated with high mortality. Recent Society for Vascular Surgery (SVS) guidelines recommend repair of all but SVS grade I injuries. This study's objective was to retrospectively determine guideline adherence at the authors' trauma center, and its impact on mortality. ⋯ Minor deviation (9.6%) from guidelines did not result in additional morbidity/mortality. However, a high rate of loss to follow-up limits conclusions. The mortality reduction seen with endovascular repair for grade 3 injury is inflated by patients who die before repair is considered in the nonoperative group. Larger prospective studies with appropriate inclusion and exclusion criteria and improved follow-up are needed to determine the consequences of selective nonoperative management of these injuries.

Comparative Study
Patterns and management of blunt abdominal aortic injury.
Blunt abdominal aortic injury (BAAI) is historically associated with significant morbidity and mortality. Our institutional experience was analyzed to define current patterns of injury and to help guide management. ⋯ Patients with MAI are at low risk of complications and may be considered for observation. Patients with SAI requiring intervention manifest clinically and/or radiographically at presentation. Those not associated with bleeding, malperfusion, or thromboembolism may be observed with interval imaging. For all observed patients, long-term surveillance is required to document complete resolution or stability, because even MAI can progress to a more complex lesion.
