摘要
为了解脑血管畸形各型的病理改变和发生率及探讨脑血管畸形出血的主要原因。观察及分析了180例脑血管畸形的病理改变，其中脑活检156例，尸检24例。按病理形态分类，有动静脉型159例，静脉型3例，海绵状血窦型6例，毛细血管扩张型1例，混合型11例。脑出血是脑血管畸形最常见的临床表现，并系引起死亡的主要原因。出血可能系畸形血管导致的局部血液动力学异常与畸形血管壁原发及继发改变综合作用的结果。此外有5例脑血管畸形伴有脑肿瘤，两者可能是偶合，在发生上无关。
180 cases of vascular malformation in brain (BVM) including 156 cases of braln biopsy and 24 autopsy cases were examined with routine pathological methods. The attempt of this study is to realize the pathological change and incidnce of each type and to find out the rnain cause of hernorrhage in BVM. According the morphological characteristics, 180 cases of BVM were classified into five types.They are: arteriovenous type 159 cases, venous type 3 cases, cavernous type 6 cases, capillary telangiectasis 1 case, and mixed type 11 cases. Hemorrhage was the most common clinical manifestation and main cause of death in BVM. The mechanism of hemorrhage may be due to either hemodynarnic disturbance in local area or changes of the blood vessel wall. Besides these, there are five cases of BVM accompanied with brain tumor- They may be two independent diseases occurred in the same person. No relationship was found between the occurrence of these 2 entities.
