[When the tissue tolerance fiber tears]

We report a 65 year old patient who presented with both an aneurysm of the axillary artery and, some years later, with an acute aortic dissection type Stanford A. After surgical intervention of the dissection in the further workup, no specific etiology could be found. The most likely reason for the two aneurysms was the inadequately treated hypertension. Therefore, follow-up strategies aim to treat the risk factors which are known to promote aneurysm growth.
