动静脉畸形(AVM)与栓塞治疗Arteriovenous malforma...

An arteriovenous malformation or an AVM is an abnormal formation of blood vessels connecting arteries and veins, BYPASSING the capillary system.
动静脉畸形或者AVM是连接动静脉之间的异常结构,绕过毛细血管系统。
The blood vessels of an AVM are commonly dilated and weakened due to high blood pressure and an AMV may bleed.
由于高血压和AMV可能会出血,AVM的血管通常会扩张和减弱。
Bleeding from an AVM may cause damage to surrounding brain tissue and result in a hemorrhagic stroke.
AVM的出血会造成周围脑组织的损伤,导致出血性的中风。
An AVM can develop anywhere in the body but occurs most ofte
n in the brain or spine.
AVM可以发展到身体的任何部位,但是最常出现在大脑和脊髓。
AVMs are mostly congenital but not hereditary.
AVM大多是先天的,但不是遗传的。
They are believed to form during embryonic or fetal development.
他们认为AVM形成于胚胎或者胎儿形成过程中。
AVM embolization is an endovascular treatment aimed to block blood flow in to an AVM and therefore reduce the risks of AVM bleeding.
AVM栓塞是一种血管内的治疗方法致力于组织血流入AVM,因此降低AVM破裂的风险。
In this procedure, a catheter is inserted through the femoral artery at the groin and threaded all the way to the brain AVM.
在这个过程中,一根导管通过股动脉插入腹股沟,并穿过所有的通路进入大脑AVM。
The catheter is used to inject a special glue into the AVM.
这个导管用于注射一种特殊的胶水到AVM中。
The glue hardens when it comes into contact with the blood and seals off the AVM from the blood flow.
当它与血液接触时,胶就变硬了,并且从血液流动中切断了AVM。
AVM blood vessels do not supply normal brain tissue and therefore their blockage will not have any consequences on the patient.
AVM并不用来供养正常的周围脑组织,因此它们的阻塞并不影响患者的任何结果。
AVM embolization is rarely successful on its own.
AVM栓塞本身很少成功。
It is useful, however, in conjunction with other procedures such as surgery or radiation.
然而,当它和手术或放射等其他过程结合时,它就是有效的。
Performing AVM embolization PRIOR to surgical removal helps to reduce significantly the risk of AVM bleeding during surgery.
在手术前进行AVM栓塞有助于显著降低手术中AVM出血的风险。
