Case Reports

Copyright © 2009 by the Congress of Neurological Surgeons Surgical clipping of paraclinoid region aneurysms can be challenging and often requires temporary interruption of local blood flow to decompress the aneurysm and to facilitate clip placement. This has traditionally been accomplished by trapping of the aneu rysm and suction decompression. Endo vascular balloon inflation across the aneurysm neck has also been used to achieve both proximal and distal control during aneurysm surgery, eliminating the need for temporary clipping. We report the use of a similar technique as a salvage procedure in the setting of intraoperative rupture without adequate proximal control. Although endovascular access was not planned preoperatively, navigation of a balloon was feasible and proved to be extremely helpful in interruption of local blood flow. Furthermore, the balloon provided intraluminal support and prevented parent artery compromise during clipping.
