Percutaneous angioplasty of long tibial occlusions in critical limb ischemia

Ann Vasc Surg. 2013 Oct;27(7):894-903. doi: 10.1016/j.avsg.2013.02.008.

Abstract

Background: The aim of this study was to assess the midterm results of percutaneous angioplasty in patients with critical limb ischemia (CLI) and long tibial occlusions.

Methods: Between January and September 2011, 34 consecutive patients with patent femoropopliteal artery and 49 segmental tibial occlusions >8 cm were included in our prospective, single-center cohort study. Clinical success (defined as wound healing and survival without major amputation), patency, and freedom from target vessel revascularization (TVR) were examined.

Results: The median age of the patients was 75 (53-89) years, 74% were diabetic, and 89% of the limbs studied were Rutherford 5 and 6. Median follow-up was 12.5 (1-15) months. The 1-year clinical success rate was 65%, higher among patients with technical success (76% vs. 25%, P = 0.01) and patients with 2 or 3 patent tibial arteries after the procedure (90% vs. 41% in patients with only 1 patent artery, P = 0.003). At 1 year, primary and secondary patency rates were 13% and 32%, respectively (24% and 58% without technical failures). The 1-year freedom-from-TVR rate was 34%.

Conclusions: Despite high technical failure rates and the need for repeat procedures, percutaneous angioplasty of long tibial occlusions enhances wound healing, especially when integrated into a maximal revascularization approach.
