摘要

本文介绍了大、巨型桥小脑角肿瘤患者脑桥及小脑组织灌注的研究结果。对10例前庭神经鞘瘤和8例颞骨脑膜瘤进行灌注ct检查。计算脑桥和小脑半球6个感兴趣区域的脑血流参数。脑桥有脑组织灌注不足和小脑半球附近充血的表现。这些变化提示手术后局部脑血流紊乱的可能性。

Investigation of tissue perfusion of the brain in patients with large and giant tumors of the bridge-cerebellar angle
The article presents the results of the study of pons and cerebellar tissue perfusion in patients with large and giant cerebellopontine angle tumors. Perfusion computed tomography was performed in 10 patients with vestibular schwannomas and 8 patients with temporal bone meningiomas. The parameters of cerebral blood flow were calculated in 6 regions of interest in the area of the pons and the cerebellar hemispheres. There are manifestations of brain tissue hypoperfusion in the pons and hyperemia in the nearby parts of the cerebellar hemisphere. The revealed changes indicate the possibility of disorders of local cerebral blood flow after surgery.
