|A||Chronic liver failure|
|C||Upper gastrointestinal bleeding|
i. Non cirrhotic Hypertension →can be due to non cirrhotic portal fibrosis (NCPF) or Extra hepatic portal venous obstruction (EHPVO)
ii. It is also called: Idiopathic portal hypertension
iii. Its incidence is very high in India accounts for 15% to 18% of all patients with portal hypertension.
Infection → It was suggested that E. coli can cause NCPF
Exposure to chemicals →Chronic ingestion of (1) Arsenic (2) Vinyl Chloride toxicity (3) Copper
Extra Edge: (Arsenic also causes skin Ca, lung Ca, hepatic angiosarcoma)
1. Massive hematemesis. (M/C presentation)
2. Rarely patient develop encephalopathy.
3. Ascites is uncommon
4. Splenomegaly is present

2. Tree in winter appearance– filling of a large number of collaterals with gross distortion of intrahepatic pattern.
3. Splenic vein is dilated and tortuous.
1) Treatment of choice is endoscopic sclero therapy.
Comparison between NCPF and EHPVO
1. Similarities between the two conditions
a. Massive variceal bleeding b. Moderate to massive splenomegaly
c. Normal liver on histology d. Absence of Ascites e. Normal liver function
2. Difference between these two conditions
a. Age of presentation
. EHPVO → Children
. NCPF → Young adult
b. Site of obstruction in the portal venous system
EHPVO → Main and 1st order branches of portal vein
c. Splenomegaly – more common in NCPF than EHPVO
