Subintimal angioplasty and stenting in chronic total femoropopliteal artery occlusions: Early- and mid-term outcomes.
BACKGROUND
This study was conducted to evaluate the initial and mid-term patency rates of chronic total femoropopliteal artery (FPA) occlusions treated by subintimal angioplasty (SIA) and stenting.


METHODS
From March 2010 to February 2013, 74 patients were included in the study. Seventy two patients with total occlusion of the FPA and good distal runoff (2 or 3 patent vessels) were treated with percutaneous SIA and stenting. All patients had severe claudication or critical limb ischemia. In all cases, the procedure was performed with a contralateral approach. Follow-up was done at 6 months with clinical evaluation and color-Doppler. If it was necessary, peripheric angiography was performed.


RESULTS
Immediate technical success was achieved in 72 (97%) patients. Two (3%) distal embolizations, 2 (3%) groin hematomas, 1 (1%) femoral pseudoaneurysm and 1 (1%) rupture of the junction-external iliac-superficial femoral artery occurred. All of the complications were treated successfully. Total occlusion in 1 patient and critical occlusion in 3 patients were showed at the 6th month. Patency rate at the sixth month was 94% with a stent length of 13.4 ± 8.2 cm.


CONCLUSIONS
Percutaneous SIA and stenting for chronic total of the FPA occlusion showed good initial and mid-term patency rates, with few periprocedural complications.
