Cerebral mycotic aneurysm treated with endovascular occlusion--case report

A 56-year-old male with two mycotic aneurysms associated with infective endocarditis was treated by endovascular surgery before mitral valve replacement. Angiography revealed a ruptured proximal aneurysm and an unruptured distal aneurysm on the right middle cerebral artery. The ruptured aneurysm was successfully treated with an interlocking detachable coil, and patency of the parent artery was preserved. The unruptured distal aneurysm disappeared as a result of antibiotic therapy. Endovascular surgery of the mycotic aneurysm is less invasive and more effective than craniotomy under general anesthesia for patients with infective endocarditis.
