Arterial Dissections After Angioplasty by Long vs Short Time of Balloon Inflation: the Randomized Controlled Trial.

Under local anesthesia the percutaneous arterial access will be created. Digital subtraction angiography of the whole limb will be performed. Occlusive-stenotic lesion of the superficial femoral and / or popliteal artery will be crossed with a guidewire. The plain old (non drug-eluting) will be positioned in the affected arterial segment and inflated up to nominal pressure. After balloon deflation and extraction the completion angiography will be performed. Presence (yes/no) and severity (grades A-B or C-F according to NHLBI classification) of dissection will be assessed independently by 3 study investigators basing on DSA images in 2 directions. Decision to classify the dissection as severe (grade C-F) and to perform the bailout stenting will be done by the agreement between at least 2 from 3 investigators.
