    Abstract:
    A 35-year-old female developed a subarachnoid hemorrhage from an aneurysm located at the fenestration of the vertebrobasilar (VB) junction. The patient was treated with Guglielmi detachable coils (GDCs). The aneurysm was successfully occluded using 8 coils despite the fact that 2 major complications occurred during the procedure: perforation of the aneurysm with a coil and thrombosis of the parent artery. The GDC that had perforated the aneurysm was left and remained partially in the subarachnoid space, and embolization was continued. The thrombus was mechanically crushed and dissolved. Forty days postoperatively, the patient was discharged home with minimal sequelae. VB junction fenestration is present in 35.5%-70% of VB junction aneurysms, but fenestration of the VB junction is sometimes overlooked on selective angiography. Careful pre-operative assessment is needed for aneurysms at the VB junction. The international subarachnoid aneurysm trial (ISAT) found that endovascular treatment was superior to surgery in the management of ruptured aneurysms. Nevertheless, thromboembolic complications and perforation are associated with coil embolization. Thus, care should be taken to avoid these complications, and it is indispensable to have appropriate treatment options immediately available to deal with them should they occur.
