Use of completion imaging during infrainguinal bypass in the Vascular Quality Initiative.

Abstract：

OBJECTIVE:The purpose of this study was to examine the practice patterns of intraoperative completion imaging (CI) for lower extremity bypass (LEB) in the Vascular Quality Initiative (VQI). METHODS:A retrospective review of all LEB procedures in the VQI database from January 2003 to October 2013 was performed. Regions with fewer than 200 LEB procedures were excluded from the regional analysis. The modality of CI was defined as duplex ultrasound, angiography, or both. RESULTS:A total of 14,140 LEBs were captured, with the rate of CI being 43%. After exclusion of three regions for insufficient volume (<200 LEBs), 13,945 LEB operations across 13 regions were available for regional analysis. Use of any type of intraoperative CI varied across regions from a low of 8% to a high of 70%, with angiography being performed most frequently. When CI was performed, the type of imaging modality varied between regions from a high of 99% for angiography to a high of 75% for duplex ultrasound. CI was more common in male patients (44% of male patients vs 42% of female patients; P = .032), diabetics (44% of diabetic patients vs 42% of nondiabetic patients; P = .026), and patients with coronary artery disease (45% of patients with coronary artery disease vs 42% of patients with no coronary artery disease; P = .0015). CI was performed less frequently in LEB using single-segment great saphenous vein vs LEB using lesser saphenous, arm, or composite vein (48% vs 57%; P < .0001). CI was used in 51% of LEBs with a tibial or pedal target vessel vs 38% of LEBs with a more proximal target vessel (P < .0001). Patients with an indication of critical limb ischemia underwent CI in 45% of LEBs vs 39% with an indication other than critical limb ischemia (P < .0001). CONCLUSIONS:Within the VQI database, considerable practice pattern variation exists in the use of CI. Currently, CI is most commonly employed for patients with critical limb ischemia, infrageniculate target vessel, and disadvantaged venous conduit. Further study is required to standardize and to define the appropriate use of CI for LEBs.
