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下隙。

So an acute subdural hematoma causes symptoms within 2 days.

急下血肿通常在2天内出现症状。

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

铅皮表面那一层渣滓的——也就是铅锈, 你看到了?

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

Robert Martin，45岁。摔伤头部，引起小面积下血肿。

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的下血肿。

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

亚急下血肿在3到14天内出现症状；慢下出血在15天后出现症状。

I have an accent, and I know how to say subdural hematoma.

我有口音，但我知道怎么说下血肿。

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

他下血肿 导致脑部出血。

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

看上去气管有损伤 你想给肿块手术?

What about an epidural to get her blood pressure down?

用不用做导管降压?

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

下出血的血液积聚在蛛网和脑内层之间。

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

下隙在大脑静脉回流中起重要作用。

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

小型的下血肿可经由颅脑钻孔，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，下血肿的轮廓和大脑轮廓一致，呈新月形，跨过颅缝。

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

脑的内层在蛛网之上，这两层中间的腔隙叫做下隙。

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

下出血的主要原因就是下隙中的桥静脉破裂。

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，急下出血形成高密度区域，慢下出血则形成低密度区域。

On a CT scan, an acute subdural hematoma shows up as a hyperdense mass, meaning that it looks more white than the surrounding healthy brain tissue.

在CT上，急下血肿为高密度区域：也就是说那块区域比旁边的正常脑组织亮度更高。

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。

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

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。
