• Intraoperative Monitoring of Blood Flow Insufficiency in the Posterior Inferior Cerebellar Artery Using Medullary Trigeminal Evoked Potential and Fluorescence Angiography

抄録

We evaluated the usefulness of medullary trigeminal evoked potential monitoring (M-TEP) and fluorescence cerebral angiography using fluorescein sodium (fluorescein-FCAG) for detecting the blood flow insufficiency in the posterior inferior cerebellar artery (PICA) during aneurysm surgery.<br> The study population consisted of 3 patients with PICA aneurysm (2 cases) and vertebral artery aneurysm (1 case). In 2 cases, after aneurysm clipping and/or trapping, M-TEP disappeared and the fluorescence of the PICA was not seen. After clip replacement (Case 1) and occipital artery (OA) - PICA anastomosis (Case 2), M-TEP returned to the control level and blood flow of PICAs were confirmed by fluorescein-FCAG. Postoperatively, incomplete Wallenberg syndrome appeared in Case 2. In Case 3, OA-PICA anastomosis was performed, and the aneurysm was trapped. Intraoperative findings of M-TEP and fluorescein-FCAG did not change. No neurological deficits appeared postoperatively. <br> Based on our findings, we suggest that M-TEP and fluorescein-FCAG are useful to prevent unexpected postoperative Wallenberg syndrome and to improve the surgical outcome.<br>
