Peripheral arterial disease is common and is associated with significant morbidity and mortality. ⋯ In patients with claudication, open surgery, endovascular therapy, and exercise therapy were superior to medical management in terms of walking distance and claudication. Choice of therapy should rely on patients' values and preferences, clinical context, and availability of operative expertise.

Multicenter Study Clinical Trial
Results of a prospective multicenter trial of CTAG thoracic endograft.
As thoracic aortic aneurysms (TAAs) are more frequently being treated with endografts, the anatomic challenges of the thoracic aorta have led to design modifications of endografts. The Conformable GORE TAG (CTAG) device (W. L. Gore & Associates, Flagstaff, Ariz) was specifically designed to be more conformable in tortuous anatomy, more resistant to compression, and more accommodating to various aortic diameters compared with the original GORE TAG device. This prospective, multicenter study evaluated the safety and effectiveness of the CTAG endograft in the repair of descending TAA. ⋯ This next-generation thoracic endograft has a low rate of major device events through 2 years, with no graft compressions or device failures. The data for this new endograft demonstrate favorable outcomes and confirm low risks for treatment for patients with TAA. Follow-up will be continued for 5 years.

Comparative Study
Limb salvage after vascular reconstruction followed by tissue transfer during the Global War on Terror.
Combat extremity wounds are complex and frequently require an immediate vascular reconstruction in the operational environment followed by delayed tissue coverage at a stateside medical treatment facility. The purpose of this study was to evaluate limb salvage outcomes after combat-related vascular reconstruction that subsequently required delayed soft tissue coverage during the Global War on Terror. ⋯ Immediate vascular repair followed by delayed tissue coverage can be performed with a high (>80%) limb salvage rate after combat trauma. Limb salvage rates were higher in the UE despite equivocally high arterial patency rates. Wounded warriors can expect limb salvage by use of this international algorithm.

A recent prospective study found that fenestrated endovascular abdominal aortic aneurysm (AAA) repair (FEVAR) was safe and effective in appropriately selected patients at experienced centers. As this new technology is disseminated to the community, it will be important to understand how this technology compares with standard endovascular AAA repair (EVAR). The goal of this study was to compare the outcomes of FEVAR vs EVAR of AAAs. ⋯ Patients undergoing FEVAR are more likely than patients undergoing EVAR to receive blood transfusions postoperatively and are more likely to sustain postoperative complications. Although mortality was similar, trends toward increased cardiac and renal complications may suggest the need for judicious dissemination of this new technology. Future research with larger number of FEVAR cases will be necessary to determine if these associations remain.

Comparative Study
Durability and survival are similar after elective endovascular and open repair of abdominal aortic aneurysms in younger patients.
The role of endovascular repair (EVAR) of aortic aneurysms in young patients is controversial. The purpose of this study was to determine the long-term outcomes and reintervention rates in patients 60 years of age or younger who underwent elective open or endovascular repair of an abdominal aortic aneurysm. ⋯ After elective aneurysm repair, younger patients have a moderate life expectancy related to malignant disease and cardiovascular health. EVAR offers durability and long-term survival similar to those with open repair in these younger patients as long as aneurysm anatomy and IFU are adhered to.
