Portopulmonary hypertension was assessed by duplex andechocardiography in 30 cases of liver cirrhosis, their age ranging from 36to 65 years, 3 females and 27 males, 10 of class B and 20 of class C. Theywere recruited from Internal Medicine Department and assessed inultrasound department of Kaser Al- Aini Hospital, Cairo University.Duplex included measurement of portal vein diameter, portal veinsystolic velocity, hepatic veins wave form changes, hepatic artery peaksystolic velocity and hepatic artery resistivity index. Whileechocardiographic examination included measurement of pulmonaryartery diameter, velocity, acceleration time, right ventricle dimension,wall thickness and tricuspid regurge (surest sign of portopulmonaryhypertension in our study).We found that portopulmonary is not an uncommon condition incases with liver cirrhosis, the incidence in our study was 10%.Doppler echocardiography is a useful screening method forportopulmonary hypertension as early echocardiographic changes. Asregards the duplex, hepatic vein wave form changes (Biphasic ormonophasic wave forms) showed a significant positive correlation withthe diameter of pulmonary artery.
