Analysis is made of the results of examination and surgical treatment of 70 patients with chronic critical upper limb ischemia. The etiology of damage was atherosclerosis – 13 (18.5%) patients, nonspecific aortoarteritis – 5 (7.1%), Raynaud's disease – 6 (8.6%), thrombangitis obliterans – 7 (10%), postembolic occlusion – 2 (2.8%) patients. Thirteen (18.5%) patients presented with complicated forms of extravasal compression of at its outlet from the chest and 24 (37.2%).patients had sequelae of arterial injuries. On the whole the incidence of critical ischemia constituted 48.8%. In proximal lesions, it accounted for 33%, in lesions of the median level for 47.5%, and in distal lesions, for 50%. Among patients with extravasal compression of the vasculoneurvons band, the incidence of critical ischemia constituted 23%. Based on the study of collateral circulation the key collateral vessels were identified: the deep brachial artery, recurrent collateral arteries in the area of the ulnar flexion and palmar arches of the hand. Factors that favour circulatory decompensation were established: extended occlusions of the distal portion of the subclavian artery, occlusions at the level of the deep brachial artery in combination with lesion of the axillary artery; bifurcation of the brachial artery; occlusions of both arteries of the forearm; obliteration of the arterial arches of the hand and digital arteries; multi-stage occlusions. The indications were elaborated for use of reconstructive and non-standeard methods of revascularization as dependent on the level of lesion. All 70 patients underwent 84 operations. After operation bypass thrombosis was recorded in (7.7%) cases; one (1.2%) patient showed no effect; three (3.6%) patients underwent amputation of the upper limb; the lethality accounted for 1.2%. In the short-term postoperative period, good results were noted in 91.6%, in the long-term period, in 88% of patients.
