  • Title: Late hemodynamic failure following percutaneous transluminal angioplasty for long and multifocal femoropopliteal stenoses.
    Author: Jørgensen B, Tønnesen KH, Holstein P.
    Journal: Cardiovasc Intervent Radiol; 1991; 14(5):290-2. PubMed ID: 1834336.
    Abstract:
    The outcome of percutaneous transluminal angioplasty (PTA) was evaluated for treatment of 87 limbs with femoropopliteal stenoses, including 55 short stenoses (2.4 +/- 1.6 cm, mean +/- SD), seven single long stenoses (10.4 +/- 2.0 cm), and 25 multifocal stenoses (2.1 +/- 1.6 cm), where two to four separate segments were dilated. Following 98% initial technical success, 3-year patency was 68% for single short stenoses, as opposed to 20% for long and multifocal stenoses (p = 0.05, logrank test). Antiplatelet therapy with acetylsalicyclic acid was not found to influence occurrence of restenosis. The study documents the poor PTA results for long and multifocal stenoses and suggests precautions to be taken during PTA in order to minimize the area of artery wall damage.
