| Abstract: | A case is presented of Subacute Bacterial Endocarditis on a biological Duramater Prosthesis. In the evolution curse, the patient presented an intraparenchimal cerebral haemorrhage, where--upon the angiographic studies demonstrated the existence of a mycotic aneurysm in the left median cerebral arterial territory. With specific antibiotic therapy and replacement of the prosthesis, the clinical evolution of the case, was positive, and later angiographies evidenced the disappearance of the aneurysm. The incidence of intracranial mycotic aneurysm complicating bacterial endocarditis is relatively high (up to 4% in post-mortem series). There have been very few cases communicated up to now with angiographic demonstration. Mortality is similar in patients under surgical or medical treatment. The aetipothogenic aspects are discussed, as well as the recommended therapeutic measures. |
