RESUMO
Tactics and results of surgical treatment of 5 patients for splenic cyst were analyzed. The original method of splenic cyst resection, using blood-preserving technologies (ultrasonic aspirator-destructor, the argon laser and hemostatics) was applied. The data obtained permit to consider the splenic resection performance an adequate procedure for the focal organ pathology treatment.

Samples of the stomach, duodenum and pancreas removed from 76 patients obtained during organ-preserving operations for ulcer and chronic pancreatitis were examined morphologically. It is found that the most frequent type of changes in the intraorgan arteries is their wall hypertrophy in combination with hyperelastosis and elastotic fibrosis. This characterizes chronic local arterial hypertension. An additional morphological symptom complex caused by a vegetative vascular crisis is formed in the arteries of the damaged organ in exacerbation of the disease. The complex includes prominent dystonic and alterative changes of small arteries leading to stasis and thrombogenesis in the microvessels. Unknown so far phenomenon of arterial invagination in 18 patients was observed. It leads to a complete block of circulation, acute ischemia followed by tissue necrosis which was most typical for ulcer exacerbation and chronic pancreatitis.

Local arterial hypertension is a morphological and functional phenomenon representing a change of the arterial channel, which is observed in a restricted part of an organ being as large as the blood supply pool of a large artery, or the pool of a separate artery. No demonstrative explanation has been found for these vascular channel changes similar to the widespread ones that are observed in case of systemic hypertension until now.
