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

所以" Subdural Hemorrhage" 指脑部血管破裂血至硬隙。

So an acute subdural hematoma causes symptoms within 2 days.

急性硬血肿通常在2天内现症状。

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

Robert Martin，45岁。摔伤头部，面积硬血肿。

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

Robert martin 45岁，摔伤头部一个的硬血肿。

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

有口音，但知道怎么说硬血肿。

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

亚急性硬血肿在3到14天内现症状；慢性硬血在15天后现症状。

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

他硬血肿 导致脑部血。

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

看上去气管有损伤 你想给硬肿块手术?

A blow to the head? A subdural hematoma?

头部受到过袭击? 硬脑血肿?

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

硬血的血液积聚在蛛网和硬脑内层之间。

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

硬隙在大脑静脉回流中重要作用。

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

型的硬血肿可经由颅脑钻孔，通过导管流治疗。

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

而慢性硬脑血肿，则显示为低密度区域，意味着比正常脑组织亮度更低。

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.

硬脑的内层在蛛网之上，这两层中间的腔隙叫做硬隙。

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

硬血的主要原因就是硬隙中的桥静脉破裂。

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，急性硬血形成高密度区域，慢性硬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，急性硬血肿为高密度区域：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.

大型的硬血肿则需要开颅手术，即取部分颅骨，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.

硬血肿也常发生于加速-减速损伤中，比如在加速行驶后突然急刹时。
