[Dynamic hepatobiliary scintigraphy in the evaluation of the efficiency of reconstructive surgery in patients after gastrectomy].

The study was aimed at defining the informative value of dynamic hepatobiliary scintigraphy (HBSG) in the evaluation of duodenal reflux in patients with postgastrectomic disorders after reconstructive surgery. HBSG was performed in 23 patients. After intravenous injection of 99mTc bromeside in a dose of 74-80 MBq, the areas concerned were identified in the projection of the liver, gallbladder, hepaticocholedochus, duodenum, and stomach for 120 minutes with 60-min cholagogic breakfast. Histrograms were plotted in the activity-time coordinates; hepatic function, gallbladder contractility, and hepaticocholedochal patency were evaluated; the duodenal motor function index and the gastroduodenal reflux were estimated. HBSG is physiological, which makes it possible to reveal duodenal motor-and-evacuation disorders, to specify the reason for poor outcomes of gastrectomy, to objectively evaluate the severity of postgastrectomic disorders, and to determine further treatment policy for this difficult group of patients.

[The role of rheological factors in circulatory disorders in patients with arteriosclerotic lesions of major arteries]. / Rol' reologicheskikh faktorov v rasstroistvakh krovoobrashcheniia u bol'nykh ateroskleroticheskim porazheniem magistral'nykh sosudov.

The blood rheologic properties were studied in 49 patients with chronic arterial insufficiency. The values of systemic and regional circulation were studied in 25 patients. Changes in blood viscosity and aggregate condition were found to play an essential role in the occurrence of general and regional hemodynamic disorders. Reversal of the syndrome of hemorrheologic disorders led to normalization of central hemodynamic and regional circulatory values in patients with atherosclerotic lesions of the great vessels in the areas with maintained blood flow in the main channels and improved essentially the blood flow distal to the occlusion of the arterial trunk.

[Role of biochemical and radiological study methods in the evaluation of prognosis in acute ischemia of the limbs]. / Rol' biokhimicheskikh i radiologicheskikh metodov issledovaniia v otsenke prognoza pri ostroi ishemii konechnostei.

Examined were 47 patients with acute ischemia of the extremities: 29--with favourable outcome, and 18-with the development of gangrene. Scintigraphy of the extremity with 99mTc-Sn-pyrophosphate was performed; urinary excretion of epinephrine and norepinephrine, DOPA and dopamine, and vanillylmandelic acid as well was studied; the content of ACTH, cortisol and cyclic adenosine monophosphate in the blood was defined. The use of radionuclide and biochemical methods of investigation permits to assess the degree of severity of the ischemic injury to the tissues of the extremities.

[Comparative evaluation of the effectiveness of hemosorption in the treatment of patients with various forms of chronic arterial insufficiency of lower limbs]. / Sravnitel'naia otsenka effektivnosti gemosorbtsii v lechenii bol'nykh s razlichnymi formami khronicheskoi arterial'noi nedostatochnosti nizhnikh konechnostei.

A comparative effectiveness of hemosorption in relation to atherosclerotic or autoimmune genesis of the disease is presented by results of the treatment of 41 patients with chronic arterial insufficiency of the extremities. The effectiveness of hemosorption is shown to be significantly higher in patients with autoimmune genesis of the disease than with atherosclerosis.
