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

硬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硬血肿。

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

Robert Martin，45岁。摔伤头部，引起小面积硬血肿。

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

硬出血主要原因就是硬中桥静脉破裂。

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

所以" Subdural Hemorrhage" 脑部血管破裂出血至硬。

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?

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

他硬血肿 导致脑部出血。

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

硬脑内层在蛛网之上，这两层中叫做硬。

So an acute subdural hematoma causes symptoms within 2 days.

急性硬血肿通常在2天内出现症状。

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

小型硬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，硬血肿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.

亚急性硬血肿在3到14天内出现症状；慢性硬出血在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，急性硬出血形成高密度区域，慢性硬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。

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.

大型硬血肿则需要开颅手术，即取部分颅骨，来清除积聚血液。

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

硬出血血液积聚在蛛网和硬脑内层之。

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.

官方死因被裁定为硬血肿或脑外伤，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。
