Overview
The exact pathogenesis of [disease name] is not fully understood.
OR
It is thought that [disease name] is the result of / is mediated by / is produced by / is caused by either [hypothesis 1], [hypothesis 2], or [hypothesis 3].
OR
[Pathogen name] is usually transmitted via the [transmission route] route to the human host.
OR
Following transmission/ingestion, the [pathogen] uses the [entry site] to invade the [cell name] cell.
OR
[Disease or malignancy name] arises from [cell name]s, which are [cell type] cells that are normally involved in [function of cells].
OR
The progression to [disease name] usually involves the [molecular pathway].
OR
The pathophysiology of [disease/malignancy] depends on the histological subtype.
Pathophysiology
Structure
It is formed by the union of the
and divides into a right and a left branch before entering the liver.
Note that the portal vein drains blood into the liver, not from the liver. The blood entering the liver from the portal vein, after being cleaned by the liver, flows into the inferior vena cava via the hepatic veins. The inferior mesenteric vein usually does not directly connect to the hepatic portal vein; it drains into the splenic vein.
Portal vein branches into many generation of vessels that open into hepatic sinusoids. Blood is recollected into the hepatic vein and enters the inferior vena cava.
Tributaries
The tributaries of the hepatic portal vein include:
Pathogenesis
- It is thought that portal vein thrombosis is the result of arterial vasodilation of the hepatic artery and venous rescue that consists the rapid development of collaterals to bypass the obstruction.
Genetics
- [Disease name] is transmitted in [mode of genetic transmission] pattern.
- Genes involved in the pathogenesis of [disease name] include [gene1], [gene2], and [gene3].
- The development of [disease name] is the result of multiple genetic mutations.
Associated Conditions
Gross Pathology
- On gross pathology, [feature1], [feature2], and [feature3] are characteristic findings of [disease name].
Microscopic Pathology
- On microscopic histopathological analysis, [feature1], [feature2], and [feature3] are characteristic findings of [disease name].
