[Multiple occlusions and stenoses of the abdominal aortic branches with development of Riolan's collateral and hypertension (author's transl)].

One case of multiple occlusions and stenoses of the abdominal aortic archs with development of Riolan's collateral in a young patient with hypertension is described. In the literature some cases are pointet out, which clinically resemble our patient and where the aetiology is not clarified. -- In the discussion about the aetiology of this vascular anomaly a developmental anomaly and mechanical compression by the crura diaphragmatica are named. We think, that an unspecific arteriitis similar to the in Japan well known Tacaysau-Aortitis must also be discussed. This unspecific arteriitis of the abdominal aorta and its branches would explain the occlusion and stenosis of several arteries with development of Riolan's collateral and manifestation of hypertension.
