An?arteriovenous?malformation?or?an?AVM?is?an?abnormal?formation?of?blood?vessels?connecting?arteries?and?veins,?BYPASSING?the?capillary?system.

動(dòng)靜脈畸形或者AVM是連接動(dòng)靜脈之間的異常結(jié)構(gòu)，繞過(guò)毛細(xì)血管系統(tǒng)。

The?blood?vessels?of?an?AVM?are?commonly?dilated?and?weakened?due?to?high?blood?pressure?and?an?AMV?may?bleed.

由于高血壓和AMV可能會(huì)出血，AVM的血管通常會(huì)擴(kuò)張和減弱。

Bleeding?from?an?AVM?may?cause?damage?to?surrounding?brain?tissue?and?result?in?a?hemorrhagic?stroke.

AVM的出血會(huì)造成周圍腦組織的損傷，導(dǎo)致出血性的中風(fēng)。

An?AVM?can?develop?anywhere?in?the?body?but?occurs?most?ofte

n?in?the?brain?or?spine.

AVM可以發(fā)展到身體的任何部位，但是最常出現(xiàn)在大腦和脊髓。

AVMs?are?mostly?congenital?but?not?hereditary.

AVM大多是先天的，但不是遺傳的。

They?are?believed?to?form?during?embryonic?or?fetal?development.

他們認(rèn)為AVM形成于胚胎或者胎兒形成過(guò)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栓塞是一種血管內(nèi)的治療方法致力于組織血流入AVM，因此降低AVM破裂的風(fēng)險(xiǎn)。

In?this?procedure, a?catheter?is?inserted?through?the?femoral?artery?at?the?groin?and?threaded?all?the?way?to?the?brain?AVM.

在這個(gè)過(guò)程中，一根導(dǎo)管通過(guò)股動(dòng)脈插入腹股溝，并穿過(guò)所有的通路進(jìn)入大腦AVM。

The?catheter?is?used?to?inject?a?special?glue?into?the?AVM.

這個(gè)導(dǎo)管用于注射一種特殊的膠水到AVM中。

The?glue?hardens?when?it?comes?into?contact?with?the?blood?and?seals?off?the?AVM?from?the?blood?flow.

當(dāng)它與血液接觸時(shí)，膠就變硬了，并且從血液流動(dòng)中切斷了AVM。

AVM?blood?vessels?do?not?supply?normal?brain?tissue?and?therefore?their?blockage?will?not?have?any?consequences?on?the?patient.

AVM并不用來(lái)供養(yǎng)正常的周圍腦組織，因此它們的阻塞并不影響患者的任何結(jié)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，當(dāng)它和手術(shù)或放射等其他過(guò)程結(jié)合時(shí)，它就是有效的。

Performing?AVM?embolization?PRIOR?to?surgical?removal?helps?to?reduce?significantly?the?risk?of?AVM?bleeding?during?surgery.

在手術(shù)前進(jìn)行AVM栓塞有助于顯著降低手術(shù)中AVM出血的風(fēng)險(xiǎn)。
