OBJECTIVES: To compare 30-day mortality and graft failure after use of prosthetic graft (PG) vs. vein graft (VG) as conduit for extra-anatomic arterial bypass (EAB).
METHODS: Patients who underwent axillary-femoral artery bypass (AFB) and femoral-femoral artery bypass (FFB) grafts were identified from the 2007-09 National Surgical Quality Improvement Program (NSQIP) database. Multivariable logistic regression analysis was performed to identify preoperative factors associated with 30-day mortality and graft failure.
RESULTS: Of the 493 patients who underwent AFB, 89 (18.05%) received a VG and 404 (81.95%) received a PG. Thirty-day mortality rates for patients receiving VG and PG were 2.25% and 6.19%, respectively (p=0.14) and graft failure rates were 6.74% and 2.97%, respectively (p=0.08). On multivariate analysis, there was no difference in 30-day mortality (odds ratio (OR)=0.53; 95% confidence interval (CI) =0.11-2.56) or graft failure rate (OR=2.38; 0.77-7.34) for patients receiving VG or PG for AFB.
Of the 1,219 patients who underwent FFB, 251(20.59%) received a VG and 968 (79.41%) received a PG. Thirty-day mortality rates for patients receiving VG and PG were 1.99% and 1.03%, respectively (p=0.21) and graft failure rates were 3.98% and 1.65%, respectively (p=0.04). On multivariate analysis, there was no difference in 30-day mortality (OR=1.45; CI=0.38-5.59) or graft failure rate (OR=2.19; CI=0.94-5.08) for patients receiving VG or PG for FFB.
CONCLUSIONS: Thirty-day mortality and graft failure rate are independent of the type of conduit used in patients undergoing extra-anatomic arterial bypass.
