来源:《THIEME Atlas of Anatomy:Head and Neuroanatomy》 p62. 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。
We report an adult ,a 40-year-old woman with brain arteriovenous malformation presenting with headache and epileptic seizures. CT scan demonstrated a Serpinginous enhanced brain lesion and angiography further supported the diagnosis with presence of tortuous, dilated and arterio-venous communicating ...

CT or MRI pictures may be used to check blood vessels and tissues in your brain. Do not enter the MRI room with anything metal. Metal can cause serious injury. Tell the healthcare provider if you have any metal in or on your body. Blood tests may be used to check your overall health...
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...
Radiation is particularly useful to treat small (under 1 in) malformations that are deep within the brain. Ionizing radiation is directed at the malformation, destroying the AVM without damaging the surrounding tissue. Radiation treatment is accomplished in a single session and it is not necessary ...
An arteriovenous malformation (AVM) is an abnormal tangle of blood vessels in the brain or spine. Some AVMs have no specific symptoms and little or no risk to one’s life or health, while others cause severe and devastating effects when they bleed. Treatment options range from conservative ...
治疗后2~3年头颅MRI显示有明确畸形血管残留,建议再次行伽玛刀治疗。建议患者行头颅CT检查明确有无畸形破裂出血。临床随访方式包括门诊、信件或邮件、电话等,以调查问卷的形式记录改良Rankin量表评分(mRS),评价患者生命质量的改善、神经功能的恢复、有无新发临床症状(再出血、神经功能障碍等)。
