Separating operations are recommended for treatment and prophylaxis of bleeding from varicose veins of gullet as a result of portocaval (azygoportal) shunting at cirrhosis and directed to its elimination using azygoportal separation. At the same time the frequency of relapse of bleeding after operations remains rather high. And the formation of new varicose nodi as a result of disorder of hepatic and splanchnic hemodynamics that inevitably appears at different dates after operation is considered as the main cause of it. At the same time an assessment of hemodynamic changes after azygoportal separation is interpreted in different ways by different authors.
Aim of research. To assess an influence of separating surgical interventions on the character of changes of splanchnic hemodynamics in patients with cirrhosis in comparison with non-operated patients with compensated and decompensated clinical course.
Material and methods. There were examined 190 patients with cirrhosis: in 133 took place gastrointestinal bleeding from varicose veins of gullet, in 57 – diuretic resistant ascites. 16 patients underwent separating operations. 20 patients underwent endoscopic sclerotherapy of gullet veins. 84 patients died during observation (7 after surgical treatment). Duration of observation was from 2-3 weeks to 2,5-3 years. All patients underwent the repeated ultrasound of abdominal cavity. There were assessed diameter of hepatic and splenic vessels; quantitative and qualitative characteristics of blood flow in hepatic and splenic arteries, portal and splenic veins.
Results of research. At assessment of splanchnic hemodynamics the changes of portal blood flow in first months after operation characterized with moderate dilation of portal vein and decrease of linear speed in it. At the same time the volumetric blood flow did not essentially change. It was noticed the decrease of volumetric blood flow in splenic vein at the expense of constriction of its lumen and decrease of linear speed in it. Arterial blood flow characterized with decrease of inflow to liver through hepatic artery and increase of blood flow through splenic artery. At later dates the character of changes of splanchnic hemodynamics after azygoportal separation was analogous on all indicators to non-operated patients at transfer from compensated to decompensated course of cirrhosis – decrease of blood flow through the portal vein and hepatic artery at relative increase of splenic blood flow. An increase of index of stagnation in the portal vein and splenic-hepatic portal index that took place in all operated patients and non-operated ones at the stage of decompensation was an unfavorable prognostic indication.
Conclusion. The character of changes of splanchnic hemodynamics after gastroesophageal separation is analogous to non-operated patients at transfer from compensated course of cirrhosis to decompensated one. Decrease of the portal blood inflow through the splenic vein is a compensatory mechanism that must decrease the portal pressure. The quality of life in postsurgical period is determined by duration of compensation of hemodynamic disorders
