• Critical limb ischemia
• Patency
• Peripheral vascular disease
• Subintimal angioplasty

Background: Subintimal percutaneous transluminal angioplasty (SIA) is a treatment option for long segment occlusions in the lower limb arteries In the present study the factors influencing success and patency following SIA in patients with TransAtlantic Inter-Society Consensus (TASC) C and D peripheral arterial disease (PAD) were investigated
Methods and Results: The 63 consecutive SIAs were performed in 54 consecutive patients suffering from limb ischemia with TASC C and D lesions Follow-up consisted of routine office visits with pulse examination, ankle brachial index (ABI), and serial surveillance by color duplex ultrasound and scanning at 3- to 6-month intervals for 1 year The morphology of lesions in all patients were type C (n=13, 20 6%) or type D (n=50, 794%) SIA was technically successful in 59 of 63 arterial occlusive lesions (93 6%) Post-procedural ABI was 0 89 0 16 The mean increase in ABI after SIA was 045 (range, 015-0 87) The primary patency rate at 12 months was 51 7% Occlusion length. lesions involving the distal superficial femoral artery (SFA), and post-procedural distal run-off vessels (P=0 04, 0.006, 0 018, respectively) were independent patency determinants by multivariate analysis
Conclusions: The length of the occlusion, lesions involving the distal SFA, and post-procedural distal run-off vessels were strong independent predictors for 1-year patency in TASC C/D severe occlusive femoropopliteal artery disease treated by SIA (Circ J 2010. 74: 1959-1964)
