Retrograde Peroneal Artery Approach to Treat Infra-Inguinal Arterial Chronic Total Occlusions: A Multicentre Experience and Technical Considerations

TL;DR

This study shows that using the peroneal artery for treating leg artery blockages is safe and effective when other methods fail.

Contribution

The study provides a multicentre evaluation of retrograde peroneal artery access for treating infra-inguinal arterial chronic total occlusions.

Findings

Retrograde peroneal artery access was successfully established in 91.9% of cases.

The complication rate from retrograde puncture was low at 2.1%.

The 30-day major adverse event rate was 1.6%.

Abstract

Background/Objectives: Retrograde access of the peroneal artery (PA) is considered technically challenging and at risk of bleeding. The aim of this multicentre retrospective study was to assess the safety, feasibility, and technical success of this access route for infrainguinal endovascular recanalizations. Methods: We retrospectively analyzed 186 consecutive patients treated over a 7-year period (May 2014–August 2021) who underwent endovascular recanalization of infra-inguinal lesions using a PA access route. In all cases, retrograde PA access was obtained following a failed attempt to cross the occlusion via the antegrade route. Results: Among the 186 patients, 120 were males (60.5%) and the mean age was 76.8 ± 10.7 years old (44–94 years). One hundred and thirteen patients (60.7%) suffered from chronic limb threatening ischemia (CLTI). All patients presented with chronic total occlusions (CTO) and a failed conventional antegrade recanalization attempt. Retrograde access was performed under angiographic guidance in 185 cases (99.5%). It was successfully established in 171 cases (91.9%). The total rate of retrograde puncture-related complications was 2.1% (two puncture site bleedings of which one necessitated fasciotomy and two cases of arteriovenous fistulas managed conservatively). The Major Adverse Event (MAE) rate at 30 days was 1.6% (3/186). Conclusions: Retrograde recanalization of challenging infra-inguinal lesions via PA is safe and effective in experienced hands.
