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硬肿。

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

所以" Subdural Hemorrhage" 指脑部管破裂出至硬。

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

Robert Martin，45岁。摔伤头部，引起小面积硬肿。

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

硬脑静脉回流中起重作用。

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

硬出的主原因就是硬中的桥静脉破裂。

So an acute subdural hematoma causes symptoms within 2 days.

急性硬肿通常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 你想给硬肿块手术?

A blow to the head? A subdural hematoma?

头部受到过袭击? 硬脑肿?

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

他硬肿 导致脑部出。

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

硬脑的内层蛛网之上，这两层中间的腔叫做硬。

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

亚急性硬肿3到14天内出现症状；慢性硬出15天后出现症状。

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

硬肿也常发生于加速-减速损伤中，比如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，液就会积聚硬形成肿。

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

硬出的液积聚蛛网和硬脑内层之间。

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

小型的硬肿可经由颅脑钻孔，通过导管引流治疗。

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

CT上，急性硬出形成高密度区域，慢性硬出则形成低密度区域。

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

所以CT上，硬肿的轮廓和脑轮廓一致，呈新月形，跨过颅缝。

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

而慢性硬脑肿，则显示为低密度区域，意味着比正常脑组织亮度更低。

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肿或脑外伤，但可以确定南斯独自一人家中。

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.

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