We studied 23 patients with cirrhosis who had undergone retroperitoneal distal splenorenal shunt without portal-azygos disconnection more than 2 yr earlier. We investigated the suitability of the Doppler technique (ultrasound + Doppler) to assess the patency and blood flow direction through the portal vein and the distal splenorenal shunt and its correlation with the continuous thermal dilution technique. The study also assessed the influence of the distal splenorenal shunt and time after surgery on portal perfusion and liver function. Ultrasound + Doppler distal splenorenal shunt thrombosis in two patients; however, none was confirmed by continuous thermal dilution. Ultrasound + Doppler flowmetry was possible in 19 patients (83%) (mean, 1.58 +/- 0.53 L/min). Distal splenorenal shunt continuous thermal dilution measurements were performed in all patients (100%), (mean, 1.65 +/- 0.5 L/min). Good correlation was seen between them (r = 0.66). Ultrasound + Doppler of the portal vein showed a hepatopetal flow in 16 patients (69.9%). Hepatic blood flow was significantly higher in patients with hepatopetal flow (p = 0.003). Hepatic clearance and intrinsic hepatic clearance of indocyanine green were significantly lower in patients with hepatofugal flow. Patients with hepatofugal flow had a higher incidence of chronic encephalopathy. None of the patients with a follow-up of less than 4 yr exhibited hepatofugal flow, whereas 7 of the 16 patients with a longer follow-up had hepatofugal flow (43.7%). The difference was statistically significant (p = 0.04). This study suggests that ultrasound + Doppler sonography may provide useful data in the evaluation of the patency and blood flow direction through the portal vein and the distal splenorenal shunt.(ABSTRACT TRUNCATED AT 250 WORDS)
