Radionuclide imaging of the inferior vena cava (RIVC) was performed by injecting [99mTc] phytate into a dorsal pedal vein, as an initial diagnostic procedure for eight patients with clinical features of Budd-Chiari syndrome. In five of them, membranous occlusion of the inferior vena cava (IVC) was proved by contrast venography and subsequent surgery. The other three patients, with histologically verified hepatocellular carcinoma, were proved to have tumor-induced narrowing or occlusion of the IVC by contrast venography. The RIVC findings include a sharply truncated inferior vena cava with marked hand-up of activity, extensive collaterals, and delayed visualization of the heart. Our results indicate that RIVC is as accurate and specific as contrast venography, by demonstrating the occlusion of the IVC and collateral circulation from the functional aspect. This simple and noninvasive method could therefore be used as a first-line test in patients with unexplained edema, ascites, superficial abdominal venous collaterals, and even in patients with hepatocellular carcinoma, for the detection of obstruction in the inferior vena cava.
通过向足背静脉注射[99mTc]植酸盐，对8例具有布加综合征临床特征的患者进行了下腔静脉放射性核素成像（RIVC），作为初步诊断程序。其中5例经静脉造影及后续手术证实为下腔静脉膜性闭塞。另外3例经组织学证实为肝细胞癌的患者，经静脉造影证实为肿瘤导致下腔静脉狭窄或闭塞。RIVC的表现包括下腔静脉突然截断，伴有明显的放射性摄取增加、广泛的侧支循环以及心脏延迟显影。我们的结果表明，RIVC通过从功能方面显示下腔静脉闭塞和侧支循环，与静脉造影一样准确和特异。因此，这种简单且无创的方法可用于原因不明的水肿、腹水、腹壁浅静脉侧支循环患者，甚至肝细胞癌患者，以检测下腔静脉阻塞。
