Editor-In-Chief: C. Michael Gibson, M.S., M.D. [1]; Associate Editor(s)-in-Chief: Soroush Seifirad, M.D.[2]

Overview

Hepatopulmonary syndrome (HPS) must be differentiated from portopulmonary hypertension (PPH) and hereditary hemorrhagic telangiectasia (HHT).

Differentiating Hepatopulmonary Syndrome from other Diseases

Hepatopulmonary syndrome (HPS) must be differentiated from portopulmonary hypertension (PPH) and hereditary hemorrhagic telangiectasia (HHT).

Differentiating hepatopulmonary syndrome from other diseases on the basis of pulse oximetry, arterial blood gas (ABG) analysis , contrast enhanced echocardiography; 99mTc scan: lung perfusion scintigraphy with technetium 99mTc labeled macro aggregated albumin, chest CT scan , pulmonary angiography, and pulmonary function test.
