Splenoportal Index on Color Doppler Ultrasound : Value as an Index for Predicting the Risk of Variceal Bleedingin Patients with Postnecrotic Liver Cirrhosis
Department of Radiology, Seoul National University College of Medicine
ABSTRACT
PURPOSE : To evaluate the splenoportal index (SPI ; splenic venous volume flow rate / portal venous volumeflow rate) for predicting the risk of variceal bleeding in patients with postnecrotic liver cirrhosis on colorDoppler ultrasound. MATERIAL & METHODS : Mean portal and splenic venous volume flow rates were measuredretrospectively with a color Doppler instrument in two groups of patients ; Group A (n = 40) had episodes ofvariceal bleeding while group B (n = 50) had not. Endoscopic findings were correlated with the SPI. RESULTS : MeanSPI was 2.10 in patients of group A, 0.73 in patients of group B. The variceal bleeding was developed in patientswith SPI over 1.0 with a sensitivity of 0.95 and specificity of 0.92, whose endoscopy revealed multiple beadedvariceal distention in the distal esophagus. CONCLUSION : SPI could be regarded as an useful index for predictingthe risk of variceal bleeding in patients with postnecrotic liver cirrhosis.
