The diagnostic evaluation of a brain arteriovenous malformation requires a thorough understanding of the imaging features seen on CT, MR, and conventional angiography. Therapeutic planning requires a comprehensive understanding of the angioarchitecture of AVMs, necessitation selective and superselective ...

An arteriovenous malformation is a tangle of dysplastic vessels (nidus) fed by arteries and drained by veins without intervening capillaries, forming a high-flow, low-resistance shunt between the arterial and venous systems. Arteriovenous malformations in the brain have a low estimated prevalence but ...
Arteriovenous malformationEmbolizationResectionRadiosurgeryArteriovenous Malformations of the brain are uncommon disorders with a prevalence of < 1%. 1,2 The incidence of asymptomatic AVMs in autopsy series is very small, and therefore it can be assumed that most or virtually all AVMs become symptomatic...
Figure 1 – Low magnification histology demonstrating an arteriovenous malformation in the brain Classification Brain AVMs can be classified by theSpetzler-Martin grading (SMG) system, with increasing SMG score relating to an increased morbidity and mortality of potential surgical resection. ...
MRI: In the posterior cortical and subcortical right temporal lobe, there are prominent serpiginous flow voids that demonstrate enhancement and measure approximately 1.9 x 1.2 x 1.1 cm, consistent with an arteriovenous malformation. The brain...

2.正常的血液流动是遵循这样一个原则:动脉主干→动脉分支→小动脉→毛细血管→小静脉→静脉属支→静脉主干;当动静脉畸形存在时,血液由动脉直接进入静脉,而没有中间的毛细血管床,这样的病变我们称之为 AVM(Arteriovenous Malformation),这是一种先天性病变。
Arteriovenous malformation is congenital abnormal vessels, mainly composed of blood supply arteries, the venous drainage of the nests and expansion. Divided into brain parenchyma (pia mater) arteriovenous malformations and dural arter...
Background and Purpose: Brain arteriovenous malformations (BAVM) presenting with hemorrhage are generally recommended for definitive treatment to prevent recurrent hemorrhage. The risk of craniotomy and resection of BAVM has been well described using the Spetzler-Martin Grading Scale, however, the ...
