ABSTRACT
OBJECTIVE:
Multiple vascular inflow reconstruction options exist for claudication, including aortofemoral bypass (AFB) and alternative inflow procedures (AIPs) such as femoral reconstruction with iliac stents, and femoral-femoral, iliofemoral, and axillofemoral bypass. Contemporary multi-institution comparison of these techniques is lacking.METHODS:
The Veterans Affairs Surgical Quality Improvement Project (VASQIP) national database (2005-2013) was used to compare AFB vs AIP in a propensity-matched analysis. Primary outcome was mortality at 30 and 90 days. Secondary outcomes included rates of postoperative complications. Multivariable regression assessed the adjusted effect of inflow procedure type on mortality.RESULTS:
A matched cohort of 748 claudicant patients (373 AFB, 375 AIP) was identified. The AFB and AIP groups had similar mean age (59.9 vs 60.8 years; P = .30), gender (P = .51), race (P = .52), recent smoking (79.1% vs 76.5%; P = .43), history of coronary artery disease (14.8% vs 14.7%; P > .99), chronic obstructive pulmonary disease (18.8% vs 18.4%; P = .92), renal insufficiency (5.9% vs 6.1%; P > .99), and diabetes (22% vs 20%; P = .53), and American Society of Anesthesiologists Physical Status Classification (P = .41). The AFB group had longer mean operative time (4.9 vs 3.5 hours; P < .0001), more senior resident assistants (72.4% vs 61.1%; P < .0001), and greater mean red blood cell transfusion (1.1 vs 0.12 units; P < .0001). AFB and AIP had similar rates of outflow bypass (1.9% vs 1.3%; P = .58) and outflow endovascular interventions (0.54% vs 1.6%; P = .29). AFB trended toward a higher rate of mortality at 30 days postoperatively (2.7% vs 0.8%; P = .06), but by 90 days, the crude mortality rates were similar for the two (2.9% vs 2.1%; P = .5). AFB had higher rates of pneumonia (5.9% vs 0.8%; P < .001), deep vein thrombosis/pulmonary embolism (1.3% vs 0%; P = .03), postoperative transfusion (2.7% vs 0.53%; P = .02), and urinary tract infection (3.5% vs 0.8%; P = .01), but similar rates of myocardial infarction (1.6% vs 0.8%; P = .34), stroke (0.8% vs 0%; P = .12), wound complications (13.1% vs 12.8%; P = .91), renal failure (1.1% vs 0.3%; P = .22), graft failure (1.3% vs 1.1%; P = .75), and return to the operating room (12.9% vs 9.6%; P = .17). Multivariable analysis showed AFB was not independently associated with mortality (odds ratio [OR], 0.48; 95% confidence interval [CI], 0.1-3.0). Significant factors included age (OR, 1.2; 95% CI, 1.1-1.4), postoperative renal insufficiency (OR, 2.5; 95% CI, 1.6-4.0), and unplanned reintubation (OR, 35.5; 95% CI, 3.1-399).CONCLUSIONS:
For claudicant patients with inflow disease, AFB has higher rates of 30-day complications and a trend toward higher mortality; however by 90 days postoperatively, the two procedure types have similar rates of mortality.
