[Roentgeno-endovascular dilatation and recanalization of the arteries in thrombosis and other occlusive diseases]

The authors analyze the results of 143 ++roentgeno-endovascular dilatations (RED) made in 89 patients during 1986-1990. RED of stenoses and occlusions of the iliac and femoral arteries over a length of less than 10 cm is feasible practically in all the patients. This intervention is safe and well tolerated by patients. As for RED of occlusions of the femoral arteries over a length of more than 15 cm beginning from the arterial ostium, the authors recommend that a popliteal access to the femoral artery be employed. Otherwise the passage of the occlusion area in the antegrade direction is impossible. At the same time in order to prevent thromboembolic complications, it is necessary to carry out intra- and postoperative anticoagulant therapy. Extended occlusions of the femoral arteries can be subjected to RED in cases where calcinosis of the arteries and thrombotic component are lacking in occlusion. RED of renal artery stenosis can be used as a method of choice in the treatment of vasorenal hypertension. RED is likely to be used for the management of stenoses of unpaired visceral arteries.
