[Surgery of bifurcation of the femoral artery in popliteal-tibial arterial occlusion].

In vascular surgery department of V. Vakhidov Research Center of Surgery 37 patients with diffuse lesion of popliteal-tibial arterial segment in combination with stenotic lesion of profound and common femoral artery were examined and operated. Examination of regional circulation before operation was made with consideration of profundo-popliteal collateral index (PPCI) which permits to evaluate features and degree of lesion of deep femoral artery (DFA). Angiography failed to defect bifurcation of the femoral artery in 17 (48.6%) cases, in 11 of them stenosis of bifurcation of the femoral artery was revealed in intraoperative revision. In these patients PPCI was 0.34 and more, high peripheral vascular resistance was seen in debitometry. The authors believe that calculation of PPCI is one of the main methods of diagnosis of femoral artery bifurcation lesions. Good and satisfactory results were seen in 29 (78.3%) patients, unsatisfactory--in 8. Amputations were performed in 3 patients. 1 patient died. Suppuration of the wounds was in 6 patients, in 4 of them--in the zone of reconstructed artery with arrhosive bleeding. It is suggested that in diffuse lesions of arteries of popliteal-tibial segment examinations of regional hemodynamics and plastic repair of DFA are most effective.

[Electrical activity of the motor units of the muscles in blood supply disorders of the latter].

Electrical activity of the motor units in the muscles (m. gastrocnemius and m. extensor hallucis brevis) in normal humans and in the patients with impaired peripheral circulation in the lower limbs was studied with the needle concentric electrodes. A reduction in the muscle action potentials under conditions of their circulation impairment was revealed; this pointed to the myogenic origin of alterations in the skeletal muscles due to the incompetence of their blood circulation.

[Anesthesia in surgical treatment of occlusive diseases of arteries of the lower limbs].

The kinetic study of a regional blood flow in the lower extremities (sphigmorphaphy, rheography) indicates its enhancement against the background of peridural blockade, employed by the authors in 480 of the total number of 1013 various operative interventinuous or prolonged peridural blockade, stabilized automatically or manually, is of a higher quality and may be recommended for a wide clinical application in these patients.
