To demonstrate streamline flow in the human portal vein, the hepatic lobar distribution of splenic flow was studied in 6 patients without liver disease and 4 patients with chronic hepatitis using a new technique, scintiphotosplenoportography, followed by 198Au-colloid liver scintigraphy. In two patients, a 99mTcO4-bolus injected into the spleen drained predominantly into the left lobe of the liver. A repeat examination performed in one patient revealed that the bolus was chiefly directed to the other lobe, the right lobe. In 3 patients, the distribution of 99mTcO4- radioactivity was the same as that observed with 198Au-colloid. In the other 5 patients the predominant distribution of 99mTcO4- was observed in the right lobe. In 8 of 11 studies, splenic flow was distributed either to the right or left lobe instead of diffusely to both lobes. This result suggests that flow in the human portal vein is streamline rather than turbulent.
为了证明人体门静脉中的层流情况，我们采用一种新技术——闪烁脾门静脉造影术，随后进行¹⁹⁸Au胶体肝闪烁扫描，对6例无肝脏疾病的患者和4例慢性肝炎患者的脾血流肝叶分布进行了研究。在2例患者中，注入脾脏的⁹⁹ᵐTcO₄团注主要引流至肝左叶。对1例患者进行的重复检查显示，团注主要流向另一叶，即肝右叶。在3例患者中，⁹⁹ᵐTcO₄放射性分布与¹⁹⁸Au胶体观察到的相同。在其他5例患者中，观察到⁹⁹ᵐTcO₄主要分布在肝右叶。在11项研究中的8项中，脾血流分布于右叶或左叶，而非弥散至两叶。这一结果表明，人体门静脉中的血流是层流而非湍流。
