Abstract

Although endovascular treatment has a high success rate, it is not clear how endovascular treatment affects cerebral perfusion and hemodynamics during the perioperative period. We evaluated changes in cerebral blood oxygenation (CBO) repeatedly after endovascular treatment employing time-resolved spectroscopy (TRS). We investigated a patient (10 months old, female) who suffered cerebral arteriovenous fistula. Cerebral angiography demonstrated a pial arteriovenous fistula with three feeders (left PICA, SCA, and AICA). TRS demonstrated a decrease of oxyhemoglobin, total hemoglobin, and oxygen saturation associated with an increase of deoxyhemoglobin in all of the regions measured just after embolization, indicating that embolization improved hyperemia caused by the AV shunt. Interestingly, progressive improvement of hyperemia was observed 3 and 8 days after embolization of the feeders. The present study demonstrated that embolization of the feeders caused progressive changes in CBO and hemodynamics during the perioperative period. TRS may be a useful tool for monitoring cerebral blood perfusion changes after endovascular surgery.
