This paper reports on the clinical applicability and efficiency of Scintiphotosplenoportography (SPSP) by means of 99mTc Pertechnetate. This diagnostic process permits obtaining the following data: actual route and patency of the portal vein, localizing of collaterals, as well as information on the actual speed of portal flow. By determining the time of transit of the radionuclid via the collateral pathways into systemic circulation, additional assessments as to the hemodynamic functional importance of these collaterals can be made. This process is of particular value for the speedy assessment of the patency of a surgically effected portocaval shunt in cases of shunt-bleeders. In patients without cirrhosis, a stop in the filling along the course of the portal vein indicates portal thrombosis. In cases of manifest cirrhosis, however, the lack of an SPSP image for the proximal portal vein and the liver itself, merely points to the existence of extensive caudal collaterals. Traumatization as the result of intrasplenal application of a volume of less than 1 ml (of tracer) remains minimal. In contrast with radiological splenoportography this methods entails practically no risks. However, as a result of the restricted field of view and the relatively coarse power of resolution, the quality obtainable by szintiphotosplenoportography is somewhat inferior to that of X-ray splenoportography.
本文报告了运用高锝[99mTc]酸盐进行脾门静脉闪烁造影（SPSP）的临床适用性和有效性。该诊断过程能够获取以下数据：门静脉的实际路径和通畅情况、侧支循环的定位，以及门静脉血流实际速度的相关信息。通过测定放射性核素经侧支循环途径进入体循环的转运时间，可以对这些侧支循环的血流动力学功能重要性进行额外评估。对于分流性出血患者手术建立的门腔分流术通畅情况的快速评估，此过程具有特殊价值。在无肝硬化的患者中，门静脉走行过程中充盈中断提示门静脉血栓形成。然而，在明显肝硬化的病例中，脾门静脉闪烁造影图像显示肝门静脉近端及肝脏本身不显影，仅提示存在广泛的尾侧支循环。脾内注入少于1毫升（示踪剂）造成的损伤极小。与放射性脾门静脉造影相比，该方法几乎没有风险。然而，由于视野受限和分辨率相对较低，脾门静脉闪烁造影所获得的图像质量略逊于X线脾门静脉造影。
