[MORPHOLOGIC CHANGES OF INTRA- AND EXTRAPANCREATIC ARTERIES IN ELDERLY AND SENILE PATIENTS IN ACUTE NECROTIC PANCREATITIS].

In 38 elderly and senile patients, in whom an acute necrotic pancreatitis (ANP) was diagnosed, morphological changes in the walls of intra- and extrapancreatic arteries were studied, including dorsal pancreatic artery, big pancreatic artery (Heller) and their branches. The patients were operated, using open surgical access, on the 10 - 26-th day after admittance to hospital for purulent-septic complications of pancreonecrosis. In total 9 (24%) patients died. Changes of intra- and extrapancreatic arteries causes the essential reduction of the splanchnic blood flow intensity and necrotic changes in pancreatic parenchyma and parapancreatic cellular space.
