[Indications for lumbar sympathectomy and prognostication of its outcome in patients with obliterating atherosclerosis of the lower extremity arteries in chronic critical tissue ischemia].

Indications for lumbar sympathectomy performance in patients, suffering obliterating atherosclerosis with chronic critical ischemia, were substantiated. To prognosticate the operation result there were analyzed clinical data and data of instrumental investigation of 290 patients, permitting to estimate the state of macrohemodynamics (roentgencontrast arteriography, ultrasonic dopplerometry, rheova-sography) and microcirculation (laser Doppler's flowmetry--LDF). Initial indices of macro- and microhemodynamics on the foot are the important prognostication factors to predict the result of operation. Positive immediate postoperative results were achieved in 93.4% of patients, including 92.1%--while taking into account the macrohemodynamics indices and 96.4%--those, depicting the state of microcirculation.
