探索脑中的畸形血管

提到畸形,很多人首先会想到＂先天不足＂这个词语。没错,脑血管畸形就是脑部血管一种先天性的发育障碍,它会导致大脑局部血管在数量或结构方面异于常人,从而对正常的大脑血流产生影响。相比于高血压或脑肿瘤,更好发于年轻人,确诊年龄主要分布于20~40岁。＂脑血管畸形＂是一个大家族。大脑血液循环十分发达,血管丰富且结构复杂,其中任何一部分如果在发育过程中出现问题,都会形成我们所说的＂脑血管畸形＂。作为神经外科医生,我们通常按照出现畸形的血管成分来为它们分类。

Vascular tumors and malformations of the colon

The term "hemangioma" refers to the common tumor of infancy that exhibits rapid postnatal growth and slow regression during childhood. It may cause confusion with venous malformations that are often incorrectly called "cavernous hemangioma". Venous malformations comprise abnormally formed channels that are lined by quiescent endothelium. Accurate diagnosis is required for selecting the appropriate treatment.
