Abstract

Purpose: To investigate the feasibility and clinical outcomes of subintimal angioplasty combined with stent implantation in patients with long, multisegmental occlusive lesions unsuitable for surgical treatment. Methods: Between 2003 and 2005, 30 patients (23 men; mean age 68 years, range 49-82) with severe claudication (Rutherford category 3, n=12) or critical limb ischemia (CLI; Rutherford category 4 or 5, n=18) underwent subintimal angioplasty with primary stenting for long (mean 28±11 cm) total occlusion in the lower limb arteries. Bypass surgery was considered unsuitable owing to inappropriate anatomy or poor distal runoff in 14 (47%) patients, severe coronary artery disease 14 (47%), or poor general condition in 2 (6%). Results: Technical success was achieved in 27 (90%) of 30 cases. The 3 technical failures were due to inability to advance the wire, to re-enter the distal lumen, and vessel rupture, respectively. Three (10%) complications occurred (1 perforation, 2 hematomas) but did not require surgery. After a mean follow-up of 13±7 months (range 3-28), 10 (37%) cases of restenosis were found in 27 patients. At 12 months, the primary patency rate was 52%, and the limb salvage rate was 83%. Conclusion: Combined use of subintimal angioplasty and stent implantation was performed safely, with a relatively high success rate and acceptable intermediate-term clinical outcomes in patients with multisegmental, long occlusions of the lower limb arteries. Therefore, this strategy can be considered an option for symptomatic relief and limb salvage in patients unsuitable for bypass surgery due to various reasons.
