Regional cerebral pulsatile hemodynamics during isocapnic and poikilocapnic hyperthermia in young men

Physiological Reports
Hyperthermia is known to induce hypocapnia‐driven reductions in cerebral blood flow; however, it is unknown if it causes changes in hemodynamic pulsatility that negatively influence cerebrovascular function.

Surgical Revascularization of the Posterior Cerebral Artery in the Treatment of Unclippable Aneurysms of the Posterior Cerebral Artery

Surgery for Cerebral Stroke, 2007
Treatment of unclippable posterior cerebral artery (PCA) aneurysms frequently requires revascularization of the PCA, especially in cases with poor collateral circulation flow. We report on the microsurgical revascularization of the PCA territories in 3 patients having PCA aneurysms. Case 1 involved a P2 partially thrombosed large aneurysm.

Fenestration of the anterior and posterior cerebral arteries in coexistence with a contralateral posterior cerebral artery of fetal origin

Surgical and Radiologic Anatomy
The present case report aims to describe the rare coexistence of three variants of the cerebral arterial system diagnosed by computed tomography angiography (CTA).A retrospective study on head and neck CTAs was performed on a Greek adult population from the Department of Radiology, University Hospital of Larissa.
