Flow?diversion?is?a?newer?endovascular?technique?used?to?treat?brain?aneurysms.

分流是更先進(jìn)的用于治療腦動脈瘤的血管內(nèi)技術(shù)。

The?procedure?involves?placing?a?flow-diverting?device?- a?specially?designed?metal?mesh?tube?-?in?the?blood?vessel?adjacent?to?the?aneurysm?to?divert?blood?flow?AWAY?from?the?aneurysm.

這個過程包含放置一個引流裝置，這個裝置是經(jīng)過特殊設(shè)計的金屬網(wǎng)孔管，需要放置在動脈瘤旁引導(dǎo)血液繞開動脈瘤流過。

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

在這個過程中，一根被金屬絲引導(dǎo)的導(dǎo)管從腹股溝的股動脈插入一直穿到受影響的大腦動脈。

The?guide-wire?is?removed.

這根金屬絲可以移除。

A?micro-catheter?carrying?the?flow-diverting?device?is?introduced?inside?the?initial?catheter?and?is?navigated?PAST?the?aneurysm?opening,?without?entering?it.

一種帶有導(dǎo)流裝置的微型導(dǎo)尿管，在最初的導(dǎo)管內(nèi)引入，并通過動脈瘤開口，而不進(jìn)入。

The?device?is?then?deployed?across?the?neck?of?the?aneurysm.

接著將此裝置通過動脈瘤的頸部展開。

The?tube?slows?and?eventually?stops?blood?flow?into?the?aneurysm,?which,?over?time,?is?believed?to?shrink?and?disappear.

這個裝置漸漸地最終阻止血液流入動脈瘤，隨著時間的推移，我們認(rèn)為它可以萎縮消失。

Flow?diversion?is?particularly?useful?for?treatment?of?large?or?wide-neck?aneurysms?where?coiling?may?be?difficult?to?perform.

分流主要用于治療那些線圈治療無效的大的或者頸部寬的動脈瘤。

It?is?also?more?suitable?for?treating?un-ruptured?aneurysms?due?to?the?fact?that?the?device?and?the?catheter?system?do?NOT?need?to?enter?the?aneurysm?itself.

由于該裝置和導(dǎo)管系統(tǒng)不需要進(jìn)入動脈瘤本身，它也更適合治療未破裂的動脈瘤。

This?significantly?reduces?the?risk?of?the?aneurysm?rupturing?during?the?procedure.

它意義重大的減少了治療過程中動脈瘤破裂的風(fēng)險。
