The liver is often involved in both primary and secondary forms of amyloidosis. Significant clinical evidence of portal hypertension is relatively uncommon and seems to be related to the reduced sinusoidal lumen and increased resistance to blood flow due to massive perisinusoidal amyloid deposits. The relationships between the pattern and extent of amyloid deposition in patients presenting with portal hypertension have not yet been clearly demonstrated. This study is focusing on the topographic distribution of amyloidosis in patients presenting with portal hypertension. The study included biopsy-proven cases of hepatic amyloidosis. The clinical, biochemical, and serological data, involvement of the extrahepatic organs, and HVPG values were recorded. Tissue sections were re-evaluated for the distribution patterns of amyloid deposits. We had 41 patients with hepatic amyloidosis, of which, 32 were male. A mixed pattern (sinusoidal and vascular) was the most common (32/41; 78%). Hepatic venous pressure gradient was available in 21 cases. Portal hypertension was found in 14 patients (14/21; 67%). Cases of portal hypertension were found to have a sinusoidal pattern (3/14; 21.4%), vascular pattern (1/14; 7.1%), or a mixed sinusoidal and vascular pattern (10/14; 71.4%). Those not having portal hypertension showed hepatic artery (HA) involvement in 6/7 (85.7%) cases. A comparative analysis between portal hypertension (PTH) and non-PTH groups showed that HA amyloid deposition was dominant in the non-PTH group (6/7; 85.7%) and sinusoidal deposition in the PTH group (13/14; 92.8%). The difference was found to be significant (P < 0.05). We found that portal hypertension was noted in cases with diffuse sinusoidal deposition or mixed sinusoidal with portal vein deposition. In the non-PHT group, the deposition was mainly in HA alone.
