Aneurysm clipping after endovascular treatment with coils: a report of eight patients.
Between January 1990 and December 1994, patients with subarachnoid hemorrhage related to ruptured aneurysms who were referred to our institution were treated by neurosurgical and neuroradiological teams. In each patient, the respective indications for neurosurgical or endovascular treatment were discussed, taking into consideration patients' age and the morphological and topographical aneurysm features. We report eight cases of patients with subarachnoid hemorrhage who underwent operations after primary endovascular procedures (Hunt and Hess scores III, IV, and V). The indications for surgical treatment were as follows. First, deliberate partial occlusion of the aneurysm (two aneurysms of the internal carotid artery and one aneurysm of the anterior communicating artery) was performed to obtain only partial clotting of the aneurysm sac by free coils. However, this procedure was discontinued in favor of the use of Guglielmi detachable coils. The second indication was partial occlusion after an endovascular procedure (two aneurysms of the middle cerebral artery and one internal carotid artery aneurysm). The third indication was re-expansion of the aneurysm 1 year after the endovascular treatment (one middle cerebral artery aneurysm). The final indication was secondary rupture of the aneurysm sac and false aneurysm around the migrating coil (one aneurysm of the pericallosal artery). During surgery, the aneurysm sac appeared translucent. The coils bulged out and stretched the aneurysm sac. One ruptured the membrane leading to a subarachnoid hemorrhage during the endovascular procedure. No hemorrhage occurred during the surgical clipping. Aneurysm obliteration was easily performed, especially when the packing was partial, but was very difficult when the complete aneurysm closure led to a stenosis of the parent vessel. A giant sylvian aneurysm rest, visible only with angiography, was left untreated. This series illustrates an original experience, which led us to conclude that aneurysm surgery with coils in place is not as difficult as is often thought.
