Portal blood flow was measured with duplex Doppler ultrasound in ten normal dogs and in ten dogs with hepatic cirrhosis induced by common bile duct ligation 4 weeks previously. Mean portal blood flow velocity in the 10 dogs with experimentally induced hepatic cirrhosis was markedly reduced (9.2 ± 1.70 cm/sec vs. normal 18.1 ± 7.6 cm/sec, p < 0.01). Mean portal blood flow was also significantly decreased compared to normal (17.2 ± 4.9 cc/min/kg versus normal 31.06 ± 9.1 cc/min/kg, p < 0.01) while portal vein diameter remained unchanged. The dogs with induced hepatic cirrhosis developed extensive extrahepatic portosystemic shunting that was confirmed at necropsy. It was concluded that decreased portal velocity and portal flow which resulted from hepatic cirrhosis was detectable noninvasively with Doppler ultrasound.
