[Use of porous polytetrafluoroethylene prostheses in reconstructive reoperations in patients with occlusive lesions of the aorta and arteries of the lower limbs]. / Primenenie protezov iz poristogo politetraftorétilena pri povtornykh rekonstruktivnykh operatsiiakh u bol'nykh s okkliuzionnymi porazheniiami aorty i arterii nizhnikh konechnostei.

The use of a new domestic vascular prosthesis "Vitaflon" in reconstructive reoperations on 21 patients was clinically estimated. The positive properties of the prosthesis such as high biological inertia, good plastic properties, strength and reliability allow this prosthesis to be recommended for using in reconstructive reoperations on the vessels.

[Roentgeno-endovascular dilatation and recanalization of the arteries in thrombosis and other occlusive diseases]. / Rentgenoéndovaskuliarnaia dilatatsiia i rakanalizatsiia arterii pri trombobliteriruiushchikh zabolevaniiakh.

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.
