Reduced risk of ICA ligation after balloon occlusion test

nrCBF and EEG Monitoring During Probatory Balloon Occlusion of the Internal Carotid Artery

Surgical treatment of tumors in the neck and throat rounding the carotid artery or of giant aneurysms originating from this vessel often makes ligation or resection of the internal carotid artery necessary. This procedure carries a 15%–30% morbidity from cerebral ischemia according to the literature (2, 7).
