This study was done to evaluate the initial and mid-term patency rates of chronic total femoropopliteal artery (FPA) occlusions treated by subintimal angioplasty and routine stenting.
Materials and methods
From March 2010 to February 2013, 74 patients were included to the study. Seventy two patients with total occlusion of the FPA and good distal runoff (two or three patent vessels) were treated with percutaneous subintimal angioplasty and routine stenting. All patients had severe claudication or critical limb ischaemia. In all cases, procedure was performed with a contralateral approach. Follow-up was done at 6 months with clinical evaluation and colour-doppler. If it had been necessary, peripheric angiography would been performed.
Immediate technical success was achieved in 72 patients (97%). Two distal embolisations (3%), 2 groin hematoma (3,%), 1 femoral pseudoaneurysm (1,%) and 1 rupture of the junction-external iliac-superficial femoral artery (1,%) occurred. All of the complications were treated successfully. Total occlusion in 1 patient and critical occlusion in 3 patients were showed at the sixth monts. Patency rates at the sixth months was 94% with a stent length of 13,4±8,2 cm.
Percutaneous subintimal angioplasty and routine stenting for chronic total of the FPA occlusion showed good initial and mid-term patency rates, with few periprocedural complications.
