The Impact of Early Perfusion CT Measurement After Extracranial-Intracranial Bypass Surgery: Results of a Pilot Study

Abstract

This pilot study demonstrates that early PCT parameters can provide immediate and detailed information about hemodynamic parameters and seems to have a predictive value regarding the morbidity of hypo- or hyperperfusion in patients after cerebral bypass surgery.

Intraoperative Perfusion Computed Tomography in Carotid Endarterectomy: Initial Experience in 16 Cases

“…Compared to the other methods of perfusion imaging, such as positron emission tomography, single-photon emission computed tomography, xenon CT, and perfusion-weighted imaging [ 5 , 14 , 15 ], PCT was shown to have advantages of simplicity, short acquisition time, and providing a high-quality image. Therefore, PCT is widely used to diagnose acute cerebral ischemic stroke [ 16 ], to access delayed ischemia in patients with subarachnoid hemorrhage [ 17 ], to measure reserve capacity in patients with carotid occlusive disease using acetazolamide [ 18 ], to evaluate the effect of endovascular treatment and extracranial-intracranial bypass surgery [ 19 , 20 ], to predict hyperperfusion after surgery [ 21 ], and to diagnose and classify brain tumors [ 22 ].…”
