Abstract
A method is described in which a combined endovascular and microneurosurgical approach
is used for clipping aneurysms of the proximal paraclinoidal segment of the internal
carotid artery. By temporary occlusion of the cervical carotid artery and continuously
retrograde sucking of blood from the distal vessel via a double lumen ballon catheter,
clip application to large and critically located aneurysms is facilitated applying
decompression to the trapped arterial segment under intraoperative somatosensory-evoked
potential (SEP) monitoring.
