Spleen was punctured with a 22 gauge needle under the ultrasonographical guidance. One half ml of 99mTc-O4- solution, which contained 10 mci of nucleide energy, was injected into the splenic parenchyma through the needle. Injected material was followed by scintillation camera.
In five cases, whose esophageal varices had been endoscopically atrophic, the splenic vein, the left renal vein, the inferior vena cava and the heart were clearly viewed in a continuity within 8 seconds from the start of injection. In one case, whose varices had recurred soon after the operation, only the collaterals were delineated. Most of them seemed running upwards alongside the esophagus. In remaining one patient, whose varices had been atrophic, the splenic vein was faintly delineated within 8 seconds. However, most of 99mTc-O4- stayed at first in the spleen. Thereafter it went out into the collaterals, the lower intercostal vein and the hemiazygos vein.
This method is less invasive than the conventional angiography. It can reveal not only the entire imaging of shunt flow but also the collaterals, if they exist. It seemed useful for the evaluation of shunt patency following distal splenorenal shunt.
