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。

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

所以" Subdural Hemorrhage" 指部血管破裂出血至下隙。

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。

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

下隙在脉回流中起重作用。

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

下出血的主原因就是下隙中的桥脉破裂。

So an acute subdural hematoma causes symptoms within 2 days.

急下血肿通常在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 你想给肿块手术?

A blow to the head? A subdural hematoma?

头部受到过袭击? 下血肿?

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

他下血肿 导致部出血。

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

的内层在蛛网之上，这两层中间的腔隙叫做下隙。

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。

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，一旦桥脉破裂，血液就会积聚在下隙形成血肿。

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.

小型的下血肿可经由颅钻孔，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.

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。

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.

而慢下血肿，则显示为低密度区域，意味着比正常组织亮度更低。

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下血肿或外伤，但可以确定南斯独自一人在家中。

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.

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组织亮度更高。
