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

硬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，伤头部引起一个小的硬膜下血肿。

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

Robert Martin，45。伤头部，引起小面积硬膜下血肿。

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

硬膜下出血的主要原因就是硬膜下隙中的桥静脉破裂。

Do you see the crust of dross or lead-rust on the surface?

铅皮表面那一层渣滓的硬膜——也就是铅锈, 你看到了吗?

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

所以" Subdural Hemorrhage" 指脑部血管破裂出血至硬膜下隙。

What about an epidural to get her blood pressure down?

用不用做硬膜导管降压?

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

硬脑膜的内层在蛛网膜之上，这两层中间的腔隙叫做硬膜下隙。

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

他硬膜下血肿 导致脑部出血。

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

小型的硬膜下血肿可经由颅脑钻孔，通过导管引流治疗。

So an acute subdural hematoma causes symptoms within 2 days.

急性硬膜下血肿通常在2天内出现症状。

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

看上去气管有损伤 你想给硬膜肿块手术?

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，硬膜下血肿的轮廓和大脑轮廓一致，呈新月形，跨过颅缝。

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

亚急性硬膜下血肿在3到14天内出现症状；慢性硬膜下出血在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，急性硬膜下出血形成高密度区域，慢性硬膜下出血则形成低密度区域。

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

硬膜下血肿也常发于加速-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，血液就会积聚在硬膜下隙形成血肿。

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

大型的硬膜下血肿则需要开颅手术，即取下部分颅骨，来清除积聚的血液。

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

硬膜下出血的血液积聚在蛛网膜和硬脑膜内层之间。

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.

官方的死因被裁定为硬膜下血肿或脑外伤，但可以确定南斯独自一人在家中。
