Research Abstract

The investigation was undertaken to measure regional potal blood flow of the liver. The measurement was performed by injecting Xenon 133 into proper hepatic artery through a ballooon catheter ans then occluding the proper hepatic artery with an inflated balloon. Data was collected using a gamma camera, and washout curves were generated. They were analyzed by the initial slope method and kety-Schmidt equation. The average regional potal blood flow were : 59.31 <plus-minus> 13.04 ml/100g per min, 58.71 <plus-minus> 14.14 ml/100g per min and 37.12 <plus-minus> 10.11 ml/100g per min in hospital controls, patients with chronic hepatitis and those with liver cirrhosis, respectively. In the patients with liver cirrhosis, the regional potal blood flow was significantly reduced (P 0.01). The reproducibility of this method was satisfactory. The measurement of regional potal blood flow will be useful to evaluate underlying liver injuries and determine indications of a transcatheter arterial embolization of the
