The subdural space plays a major role in venous blood drainage in the brain.

膜下隙在大脑静脉回流中起重要作用。

Robert Martin, 45, collapsed and hit his head, causing a small subdural hemorrhage.

Robert martin 45岁，摔伤头部引起一个小膜下肿。

Robert Martin, 45. Collapsed and hit his head, which caused a small subdural hemorrhage.

Robert Martin，45岁。摔伤头部，引起小面积膜下肿。

The internal layer of the dura mater lies above the arachnoid mater and the two are separated by the subdural space.

脑膜内层在蛛网膜之上，这两层中间腔隙膜下隙。

So the main cause of a subdural hemorrhage is a rupture of the bridging veins located in the subdural space.

膜下出要原因就是膜下隙中桥静脉破裂。

So a subdural hemorrhage is when there's bleeding below the dura mater.

所以" Subdural Hemorrhage" 指脑部管破裂出至膜下隙。

He has a subdural hematoma, which is bleeding in the brain.

他膜下肿 导致脑部出。

It looks like he hasa tracheal injury. You going into the O.R.For the subdural?

看上去气管有损伤 你想给膜肿块手术?

A blow to the head? A subdural hematoma?

头部受到过袭击? 脑膜下肿?

Small subdural hematomas are drained by placing a small tube called a catheter through a drilled hole in the skull.

小型膜下肿可由颅脑钻孔，通过导管引流治疗。

So on a CT scan, subdural hematomas follow the contour of the brain and form a crescent shape and cross suture lines.

所以在CT上，膜下肿轮廓和大脑轮廓一致，呈新月形，跨过颅缝。

So an acute subdural hematoma causes symptoms within 2 days.

急性膜下肿通常在2天内出现症状。

Subdural hematomas can also happen after an acceleration-deceleration injury like speeding on the road and then suddenly slamming on the brakes.

膜下肿也常发生于加速-减速损伤中，比如在加速行驶后突然急刹时。

Regardless of the mechanism, once a bridging vein is torn, the blood pools in the subdural space and creates a hematoma.

无论何种机制，一旦桥静脉破裂，液就会积聚在膜下隙形成肿。

Large subdural hematomas require a craniotomy, which is when part of the skull bone is removed in order to remove the accumulated blood below.

大型膜下肿则需要开颅手术，即取下部分颅骨，来清除积聚液。

A subacute subdural hematoma causes symptoms between 3 and 14 days, and a chronic subdural hematoma causes symptoms after 15 days.

亚急性膜下肿在3到14天内出现症状；慢性膜下出在15天后出现症状。

On a CT scan, an acute subdural hemorrhage forms a hyperdense blood collection, whereas a chronic subdural hemorrhage forms a hypodense blood collection.

在CT上，急性膜下出形成高密度区域，慢性膜下出则形成低密度区域。

The blood in a subdural hemorrhage is located between the arachnoid mater and the inner layer of the dura mater.

膜下出液积聚在蛛网膜和脑膜内层之间。

The official cause of death was ruled as a subdural hematoma, or a traumatic brain injury, but it was established that Nance was alone in his home.

官方死因被裁定为膜下肿或脑外伤，但可以确定南斯独自一人在家中。

A chronic subdural hematoma, on the other hand, shows up as a hypodense mass, which is less white than the surrounding brain tissue.

而慢性脑膜下肿，则显示为低密度区域，意味着比正常脑组织亮度更低。
