Abstract:
Patients diagnosed as infective endocarditis(IE) are prone to follow with a variety of brain lesions, among which infective intracranial aneurysm(IIA) is a very rare cerebrovascular disease, could also be found in IE patients. IIA always has a great influence on patients’ prognoses. The incidence of this kind of aneurysm varies in different investigations, and was reported in mostly about 10% of cerebrovascular complications. The most popular pathogens causing IIA are streptococci and staphylococci, which are similar to the common pathogens of IE. IIA is a kind of pseudoaneurysm with various pathological changes and pathogenesis. The diameter of aneurysm would increases gradually with the time passing, and finally ends with intracranial hemorrhage or subarachnoid hemorrhage. The examination methods mainly include cerebral-enhanced CT and cerebral contrast-enhanced magnetic resonance imaging, but cerebral angiography is still the gold standard. There are drug therapy, surgery, interventional therapy, and other treatment methods. At present, interventional therapy is the first choice in clinical practice. Surgery is recommended if intervention is unavailable. In terms of the relationship between the operation of IE and IIA treatment, there is still a lack of evidence to give priority to cardiac surgery or IIA. Therefore, it should be considered individually according to the patient’s specific situation.
