Higher portal vein pressure means that fluid in blood vessels is more likely to get pushed into tissues and across tissues into large open spaces like the peritoneal cavity.

较高压力意味着血管中更容易穿透血管壁，被挤压进入组织，更有甚者穿过组织，进入更大开放空间，如腹膜腔。

It was a lucky shot (or unlucky, depending on your point of view, I guess) , hitting the portal vein and killing her.

她很幸运（也许你会说不幸，视你观点而定），击中了大动导死亡。

Now, the portal venous system comprises of the portal vein and its tributaries, namely the Splenic and Mesenteric veins.

系统由和其支流组成，包括脾和肠系膜。

The most common pre-hepatic cause is portal vein obstruction, like when there's a thrombus occluding the portal vein and blocking blood flow.

最常见肝前型病因是阻塞，例如当有栓子阻塞血流时。

As the central veins and sinusoids become compressed and push on the fluid inside, their pressure starts to build up, leading to intrasinusoidal (or portal) hypertension, which is this higher pressure in the portal veins.

中央和血窦受压导它们中间也受到挤压，导高压，即压力升高。

This happens when there's an obstruction in the passage of blood from the portal vein towards the vena cava.

当血从流向腔通道阻塞时，就会发生这种情况。

Here's a pretty basic layout of the basic functional unit of the liver, you've got the portal vein and hepatic artery that combine into a sinusoid, which then goes into the central vein, and these are all lined with hepatocytes.

这是一个肝脏基本功能单位简单示意图，你可以看到由和肝动来血在血窦汇集，然后流入中央，这些都与干细胞相平行。

With TIPS, a tube is inserted via a catheter to allow communication between the portal vein and hepatic vein.

使用TIPS时，可通过小导管插入大导管，以实现和肝之间连通。

But in some situations, an obstruction may prevent blood flow from the portal vein towards the inferior vena cava.

但有时从流到下腔血流会受阻。

The gold standard for determining if there is portal hypertension is obtaining a hepatic venous pressure gradient measurement where a catheter is inserted inside the inferior vena cava and then inside the portal vein to measure the difference between both pressures.

确定是否存在高压症金标准是测量肝压力梯度，即将导管先后插入下腔、内测量两个压力之间差异。
