So-called "primary" infected aneurysms of the sub-renal abdominal aorta. Five observations

The authors describe 5 cases of mycotic aneurysms of the infrarenal abdominal aorta. These relatively rare lesions raise problems which are not so much diagnostic but above all therapeutic and etiopathogenic. They are rare lesions, with a striking clinical picture and often very spectacular radiological appearances, in particular by CT scan and angiography. Indications for surgery as well as the technique used thus comply with rigorous norms. However, despite everything, and in particular despite increasingly early positive diagnosis, rapid surgical management and advances in vascular surgery techniques, the mortality associated with such lesions remains very high, even in the context of cold aneurysm surgery, when compared with ordinary atherosclerotic aneurysms, dealt with under the same conditions.
