Endovascular coil embolisation of metachronous mycotic aneurysms. Case presentation and review of technical and management issues.
While receiving optimal antibiotic therapy for subacute bacterial endocarditis (SBE), a teenage girl with mild congenital mitral insufficiency presented with two separate episodes of subarachnoid haemorrhage from two rapidly evolving metachronous mycotic aneurysms within the vertebrobasilar circulation. Both aneurysms were successfully treated by endovascular coil embolisation with the GDC system. This permitted at the minimum, successful amelioration of the short term risk of rerupture of the aneurysms, and facilitated operative management of the patient's infected mitral valve. The case further illustrates the utility and effectiveness of endovascular therapy for managing not only the neurovascular sequelae of SBE, but also perhaps the enhanced ability to optimally manage the source of mycotic aneurysms. In addition, the potential limitations and risks of this therapeutic strategy are assessed.
