Abstract

Objectives: Surgical thrombectomy has been established as an effective treatment for acute limb ischemia (ALI). Nevertheless, manipulation via the common femoral artery (CFA) to retrieve thrombus in the infra-popliteal artery sometimes proves less effective.

Methods: We retrospectively reviewed patients undergoing surgical thrombectomy for infra-inguinal ALI from January 2010 to December 2022. The primary endpoint was the rate of amputation. Secondary endpoints were technical and clinical success rates, incidence of distal embolism, and freedom from reintervention.

Results: A total of 35 patients underwent surgical thrombectomy where the popliteal artery or below is occluded. The CFA approach was utilized in 13, and the below-knee popliteal artery (BKPA) approach in 22. There were no differences in background between groups. The reintervention rate was lower in the BKPA group (BKPA group: 0% vs. CFA group: 30.8%; P = 0.01). The BKPA group showed a significantly lower incidence of distal embolism (BKPA group: 4.5% vs. CFA group: 38.5%; P = 0.02) and freedom from reintervention (BKPA group 100% at 12 months vs. CFA group: 68.7% at 12 months; log-rank P = 0.01).

Conclusions: The BKPA approach-first strategy for surgical thrombectomy in the management of ALI is feasible with better outcomes compared with the CFA approach.
