Comparative Study
Surgical bypass vs endovascular treatment for patients with supra-aortic arterial occlusive disease due to Takayasu arteritis.
This study compared treatment outcomes of patients with supra-aortic arterial (SAA) occlusive disease due to Takayasu arteritis (TA) treated with bypass surgery or endovascular treatment. ⋯ Surgical or endovascular interventions were required in one of 10 TA patients with SAA occlusive lesions. Arteries reconstructed after surgical bypass had superior patency to those reconstructed by endovascular treatment. However, bypass surgery was more likely than endovascular treatment to be accompanied by serious early postoperative complications.

With the passage of the Affordable Care Act, accountable care organizations (ACOs) represent a new paradigm in healthcare payment reform. Designed to limit growth in spending while preserving quality, these organizations aim to incant physicians to lower costs by returning a portion of the savings realized by cost-effective, evidence-based care back to the ACO. ⋯ Third, because quality metrics are central to the use and implementation of ACOs, we describe current efforts to design, collect, and interpret quality metrics in vascular surgery. And fourth, because a "seat at the table" will be an important key to success for vascular surgeons in these efforts, we discuss how vascular surgeons can participate and lead efforts within ACOs.

Peripherally inserted central catheters (PICCs) may be complicated by upper extremity (UE) superficial (SVT) or deep venous thrombosis (DVT). The purpose of this study was to determine current PICC insertion patterns and if any PICC or patient characteristics were associated with venous thrombotic complications. ⋯ The incidence of symptomatic PICC-associated UE DVT is low, but given the number of PICCs placed each year, they account for up to 35% of all diagnosed UE DVTs. Larger-diameter PICCs and malignancy increase the risk for DVT, and further studies are needed to evaluate the optimal vein of first choice for PICC insertion.

Device-related complications in the thoracic aorta are partly due to the unavoidable proximal angulation and increased flow-related forces. The present study evaluated the incidence, predictors, and outcome of the complication of infolding with the GORE TAG thoracic endoprosthesis (TAG device) to better understand the factors that might help predict these events. ⋯ TAG device infolding appears to be an infrequent event, primarily occurring in young trauma patients secondary to excessive oversizing and severe proximal aortic angulation. However, there clearly exists a need for devices that treat such patients. As a result, future device designs should consider the compression failure mode when being designed in order to help prevent such events.

Multicenter Study Clinical Trial
Prospective multicenter clinical trial (STABLE) on the endovascular treatment of complicated type B aortic dissection using a composite device design.
This study evaluates the safety and effectiveness of a unique composite thoracic endovascular aneurysm repair (TEVAR) construct (proximal stent graft and distal bare metal stent) for the treatment of patients with complicated type B aortic dissection (cTBAD). ⋯ Initial data with a composite TEVAR construct have demonstrated favorable clinical and anatomic results. Continued enrollment and long-term data are needed to assess the overall effectiveness of this treatment strategy.
