Characterizing resolution of catheter-associated upper extremity deep venous thrombosis.

Objective: Catheter-associated upper extremity deep venous thrombosis (CAUEDVT) is well known; however, resolution rates and factors affecting resolution of CAUEDVT are not well characterized. This study determined resolution rates and factors associated with resolution of CAUEDVT.

Methods: From January 1, 2002, to June 30, 2006, 1761 upper extremity venous duplex ultrasound (DU) studies were performed, and a new UEDVT was found in 253 (14.

Aortic aneurysm sac pressure measurements after endovascular repair using an implantable remote sensor: initial experience and short-term follow-up.

The purpose of this single-center study was to report our initial experience with an implantable remote pressure sensor for aneurysm sac pressure measurement in patients post-endovascular aneurysm repair (EVAR) including short-term follow-up. A pressure sensor (EndoSure, Atlanta, GA) was implanted in 12 patients treated with different commercially available aortic endografts for EVAR. Pressure was read pre- and post-EVAR in the operating room.

Duplex scan characteristics of bypass grafts to mesenteric arteries.

Background: Mesenteric bypass grafts may be followed postoperatively with duplex scanning. It is unknown, however, if duplex-derived velocity measurements vary over time or if the type of procedure (antegrade vs retrograde) and the caliber of graft affect velocity measurements. The purpose of this study was to characterize duplex findings in mesenteric bypass grafts with respect to the type of revascularization, graft caliber, and changes over time.
