Infection Risk Following Common Femoral Artery Endarterectomy Versus a Hybrid Procedure

Hybrid revascularization combines open lower extremity surgery and endovascular procedures to simultaneously treat atherosclerotic lesions on multiple levels in patients with peripheral arterial occlusive disease (PAD). Hybrid surgery appears to be a safe strategy for multilevel stenosis revascularization, though the risk of surgical site infection (SSI) has not been clearly investigated. This study evaluates the development of SSI following common femoral artery endarterectomy (CFE) and hybrid revascularization procedures.

A retrospective study was performed including all patients undergoing CFE, as standalone or as part of a hybrid procedure, due to PAD between January 2013 and December 2016. Preoperative, intraoperative, clinical, and follow-up information was gathered prospectively and reviewed retrospectively. The presence of SSI was recorded based on criteria of the Centre for Disease Control.

A total of 229 CFEs were performed. One hundred thirty-two as a standalone procedure, 65 combined with iliofemoral angioplasty, and 32 combined with peripheral angioplasty. Nineteen patients (8.3%) developed an SSI, of which 4 were deep infections. Ten infections (7.6%) occurred in the CFE-only group, 5 (7.7%) in the iliofemoral hybrid group, and 4 (12.5%) in the peripheral hybrid group (P = 0.65). Five patients (2.1%) required surgery to control the infection. The mean duration of stay was 5 days for patients without SSI versus 20 days for patients who developed an SSI (P < 0.0001).

The hybrid procedure combining open femoral endarterectomy with endovascular revascularization is a safe procedure with no significant differences in infection rates between open surgery, central, or peripheral hybrid revascularization.
