Obliterative Hepatocavopathy: The “Acrobatic Dolphin” Mimic as Endovascular Procedure Guide

Year: 2025

Type: article

Abstract: Obliterative hepatocavopathy, also known as membranous obstruction of the inferior venacava, is a frequently underdiagnosed vascular condition, seen particularly in low socioeconomic populations in India, Nepal and other parts of Asia. This viewpoint presents a distinctive radiographic analogy- the "Acrobatic Dolphin" mimic-observed during venacavography in a patient with membranous inferior venacava obstruction. The dolphin-like configuration, best appreciated in the left anterior oblique view, featured a conical beak-shaped membrane formed by flow dynamics that served both as a diagnostic clue and as an endovascular procedural guide for successful membranotomy. Moreover, recognition of such radiological signs provides powerful mnemonics that enhance clinical education.
