Overview
Based on the etiology, portal hypertension may be classified as pre-hepatic, intra-hepatic, and post-hepatic. Intra-hepatic portal hypertension classified into pre-sinusoidal, sinusoidal, and post-sinusoidal disorders. Based on the functional impairment in the liver, portal hypertension may be classified as cirrhotic and non-cirrhotic.
Classification
- Based on the etiology, portal hypertension may be classified as pre-hepatic, intra-hepatic, and post-hepatic.
- Intra-hepatic portal hypertension classified into pre-sinusoidal, sinusoidal, and post-sinusoidal disorders.
- Based on the functional impairment in the liver, portal hypertension may be classified as cirrhotic and non-cirrhotic.[1]

Idiopathic portal hypertension (IPH)
- Idiopathic portal hypertension (IPH) is due to obstruction and stenosis of intra-hepatic portal vasculature.[5]
- Idiopathic portal hypertension (IPH) has 4 stages:[5]
- Stage I: Non-atrophic liver without subcapsular parenchymal atrophy.
- Stage II: Non-atrophic liver with subcapsular parenchymal atrophy.
- Stage III: Atrophic liver with subcapsular parenchymal atrophy.
- Stage IV: Portal venous occlusive thrombosis.
