[Fibrous periarteritis of the retroperitoneal space and mediastinum as a cause of extravasal arterial compression].

Under analysis there were 14 patients operated upon for fibrous periarteritis. In 10 patients there was a retroperitoneal localization of the pathological process, and 4 patients had the mediastinal localization. The both localizations have similar features of etiology, pathogenesis, clinical course and lead to the formation of a stenosing scarry housing around the arteries with an issue into the occlusion. The operation volume for the retroperitoneal and mediastinal localization of the fibrous periarteritis depends on the stage of the disease: decompression and arteriolysis at first stages for stenosis and reconstructive operations for occlusions of the arteries.
