[Local and individual features of angioarchitectonics of the stomach and their significance in manifestation of bleedings].

The investigation has shown that on the lesser curvature in the area of the body and cardial part of the stomach there is a 2.3+/-0.3 cm section where there are no large branches of the left gastric artery and tributaries of the coronary vein. In the antral portion of the stomach such a section is not determined. Here there are terminal branches of the posterior descending and right gastric arteries. However, the diameter of these arteries when introduced into the gastric wall is rarely more than 1 mm. In addition, the arterial loops of the first and second order are formed on the anterior and posterior walls of the antral portion by the arteries of less diameter than in other parts of the stomach. In cases of the bleeding complicating the gastric ulcer it can be observed from any part of blood circulation, but the severity of bleeding is mainly dependent on the erosion of the arterial vessels. Hence, the site of the ulcer in the zone of the invasion of large arterial vessels into the gastric wall and their presence in the crater in the endoscopy picture should incline the surgeon to operative intervention.
