| ABSTRACT |
|
Microsurgical clipping is considered the treatment of choice for ruptured intracranial aneurysms. However, ruptured posterior circulation aneurysms remain technically difficult to expose or clip and outcomes in these cases are poorer than those seen in cases of anterior circulation aneurysms.
Therefore, endovascular treatment becomes another treatment option in cases of ruptured posterior circulation aneurysms.
But, the vertebral artery may not be selected due to luminal narrowing, which are atherosclerotic stenosis clinically, congenital anomalies, or acquired kinking, and structural problem of angle between aorta, subclavian artery and vertebral artery. In these cases, other approaches can be used through, for example, subclavian, axillary, or brachial artery approach. But sometimes such prcedures may be also inappropriate. One other approach is direct percutaneous vertebral artery approach. Though this one also doesn't overcome many clinical and anatomical problems. The authors present two cases of ruptured basilar tip aneurysms which was treated with endovascular Guglielmi detachable coil embolization with open surgery and catheterization, because the one had anatomical problem, and the other had structural problem. |
