[Blood-pool-SPECT for imaging portosystemic collaterals in portal hypertension].
In 46 patients, 26 male and 20 female, age from 32 to 71 years (mean 47.4 +/- 11 years) a bloodpool-scintigraphy (BPS) with SPECT (single photon emission computed tomography) was performed. The in-vivo labelling of the erythrocytes with pyrophosphate and Tc-99m was performed in the usual way. The SPECT investigations were performed with a digital Anger-Camera (Elscint; Apex 401). In 14 patients without collaterals BPS was performed to compare the method with patients with liver diseases and collaterals. 29 patients with liver cirrhosis and portal hypertension were investigated with the BPS and additionally a scintisplenoportography (SSP) was performed. In patients with only cephalad collaterals all the results were concordant. In just 1 patient with cephalad and caudad collaterals we found a discordant result. In 8 patients we performed BPS, SSP and a katheterangiography (KA). Taking the KA as the "golden standard" we found a concordant result with the 3 methods in all patients with cephalad collaterals. In patients with cephalad and caudad collaterals we once found a discordant result with the SSP and twice with the BSP. In 2 patients the patency of surgical shunts were proved. 2 patients after sclerosis of the oesophageal varices have been proved by BPS and SSP and both patients showed good therapeutical results.
