title: [Development of collateral circulation following an experimental gunshot wound to the shoulder].
abstract: Peculiarities in the development of collateral blood circulation and skin temperature of the foreleg were studied in two series of experiments (38 dogs) after gunshot wound of the humeral area, lesion of vessel-nervous bundle (first series) and humeral artery resection with section of medial and ulnar nerves (second series). In animals of the first series, the blood circulation was states to restore within a month at the expense of the arteries of the posterior humeral muscles, mainly. Further circulatroy improvement develops due to anastomoses in the anterior humeral muscles, as well as some intrasystemic roundabout ways in humeral area and shoulder girdle. Three months later, the humeral vessels network increases, it does not prevent, however, trophic ulceration of the ulnar skin. Skin temperature of the distal extremital parts raised to normal by 19--20 day of the experiment. The animals from the second series demonstrated retarded development of the roundabout ways in the operated extremities during the whole follow-up period (180 days). Skin temperature was lowered during the first 3--4 days, gradually reached the temperature of the contralateral extremity.
