Intrapulmonary vascular dilatation in portal hypertension due to cirrhosis of liver.

ABSTRACT

BACKGROUND: Intrapulmonary vascular dilatation in patients with portal hypertension due to chronic liver disease has been reported mainly from Western countries. METHODS: Fifty in-patients with portal hypertension due to cirrhosis of the liver were subjected to contrast-enhanced two-dimensional echocardiography in order to detect the presence of intrapulmonary vascular dilatation. Their arterial blood oxygen saturation was measured. The patients, including 37 men, were aged mean 43.5 years; 30 had alcoholic cirrhosis and 20 postnecrotic cirrhosis. Twelve patients were in Child-Pugh, class B and 38 in class C. RESULTS: None of the 50 patients was cyanosed or had clubbing. Their mean pO2 was 83.2 mmHg. None had evidence of intrapulmonary vascular dilatations. CONCLUSION: Intrapulmonary vascular dilatation was not observed in our patients with liver cirrhosis. However, the sensitivity of contrast-enhanced echocardiography for this purpose needs to be reviewed.
