[Surgical treatment of juxtarenal occlusion of the abdominal aorta].

Incidence, etiology and clinical course of chronic juxtarenal occlusion of the abdominal aorta have been studied. It was established that this type of lesion among other forms of occlusive disease of the aorto-ileal segment is encountered in 8.1% of patients. Inflammatory diseases of arteries prevailed as an etiologic factor. Diagnosis of this disease should be based on the use of complex up-to-date methods of examination. Roentgeno-contrast aortography in lateral position is of paramount importance in detection of upper level of thrombus spreading in the aorta. Original method of operative procedure used in 20 patients, has been developed with due regards for location of the occlusion, character of lesion of aortic walls and prophylaxis of intraoperative embolic complications. Restoration of blood flow in lower extremities without any intraoperative complications was obtained in all operated patients. In all suffering from symptomatic hypertension normalization of arterial pressure was obtained after the operation. Postoperative mortality rate made up 4.4%. The results obtained confirm high effectiveness of the above surgical treatment of patients with juxtarenal occlusion of the abdominal aorta.
