“…5 Shibata et al 10 reported that the use of intraoperative microvascular Doppler sonography (MDS) decreased the incidence of postoperative AchoA syndrome from 16% to 5%. More recently, Suzuki et al 11 reported that intraoperative monitoring of MEPs in 108 patients with ICA aneurysms was reliable for detecting insufficiency of AchoA perfusion intraoperatively. In our study, intraoperative monitoring of MEPs was not routinely used, but intraoperative MDS was used.…”

“…3,4,7,18,19,34,40,48,60 Intraoperative mapping and monitoring involving CMAPs is a valid modality for reducing iatrogenic morbidity during surgery in and around the central region as well as for intracranial aneurysms. 7,10,11,26,38,39,42,44,[49][50][51][52]62 Two methods are used for intraoperative mapping and monitoring during surgery in and around the insula. The first is the TCES of the motor cortex.…”

Object The treatment of insular tumors is controversial. Surgical treatment is associated with a higher morbidity rate than other therapies. The present work presents a new method in which the descending motor pathways are monitored during surgery for insular tumors. Methods Intraoperative monitoring was performed in a combination of 2 techniques. The motor cortex was stimulated with a transcranial electrical stimulus. In addition, direct subcortical stimulation was performed with an electrical anodal monopolar stimulus. Compound motor action potentials (CMAPs) were recorded from target muscles. Results Fifteen patients were included in this preliminary study. Following transcranial stimulation, CMAPs were recorded in all cases. Subcortical stimulation was successful in 12 cases. Significant CMAP alterations were recorded in 5 patients. There were no false-negative results in the series. Conclusions The technique presented here is a safe method. It allows a quantitative monitoring of motor function and functional mapping of the pyramidal tract during insular surgery.

A 45-year-old woman presented with kissing aneurysms located at the junctions of the internal carotid artery and the duplicate anterior choroidal arteries manifesting as acute subarachnoid hemorrhage. The aneurysms were clipped during temporary occlusion of the internal carotid artery. Surgery for kissing aneurysms requires special consideration including analysis of the anatomical relationship before clipping, control of premature rupture during clipping, and preservation of the patency of the two anterior choroidal arteries after clipping.
