动静脉畸形(Arteriovenous malformation,AVM)由动脉和静脉直接异常交通形成,缺乏毛细血管床,是一种快速血流的血管畸形。AVM是青壮年脑出血的重要原因之一,深入了解AVM的遗传发病机制是必要的。该团队前期在脑和脊髓AVM患者中发现了KRAS/BRAF的高...
Brain arteriovenous malformations (AVM's) are developmental, chronic lesions that provide unique information about the human brain and can be a useful model for neuroscientists to study cerebral reorganization and hemodynamics. We review the neuroanatomy, epidemiology, natural history, imaging and ...

脑干动静脉畸形(brainstem arteriovenous malformation,BS-AVMs)占所有颅内AVM的2-6%,其破裂风险45-88%,高于其它部位的AVM。因该部位解剖结构重要,BS-AVM出血往往导致较高的致残率和死亡率。BS-AVM的治疗原则是尽量减少并发症,避免继发出血。由于脑功能区的特殊性,显微外科手术切除BS-AVM面临着巨大的挑战。长期随访显...

脑动静脉畸形(arteriovenous malformation,AVM)是脑血管先天性、非肿瘤性发育异常,是指脑血管发育障碍而引起的脑局部血管数量和结构异常,并对正常脑血流产生影响。脑动静脉畸形可以描述为一簇异常的动脉和静脉纠缠在一起,形成像毛线团一样的血管丛,它是先天性的,随着年龄的增长,脑动静脉畸形可能会逐渐增大。
Individuals diagnosed with a brain arteriovenous malformation (AVM), an abnormal tangle of arteries and veins, are at an increased risk of vessel rupture and bleeding that can cause stroke and permanent brain damage. Traditionally, doctors have advocated preventative interventions, such as endovascular ...
Purpose To evaluate the value and limitation of MRI, especially MRA in the diagnosis of arteriovenous malformation(AVM) of brain. Materials and Methods The results of MRI and MRA in 16 cases with AVM were compared with that of DSA. The feeding arteries, nidus and draining veins were observed...
