[New method of simultaneous disobliteration of the visceral arteries and abdominal aorta].

Simultaneous correction of abnormal blood flow is necessary in the presence of combined lesions of various branches of the abdominal aorta. The problem can be solved comparatively easily by using transaortic endoarteriectomy, a technique proposed here, which consists essentially of longitudinal incision of the aortic lumen and simultaneous endoarteriectomy under the visual control of the abdominal aorta, the visceral branches and the renal arteries. Personal experience is based on 21 operations for cases of atherosclerosis and aspecific sclerotic aorta-arteritis. Simultaneous transaortic endarteriectomy is indicated in the presence of lesions localized at the proximal segment of more than two branches of the abdominal aorta. In 4 of the cases observed it was associated with resection and prosthesis of the lesioned segment of the artery and in 9 cases with resection of the abdominal aorta and aorto-femoral prosthesis. Clinical succe-s was achieved in 10 cases (90.5%).
