Budd-Chiari syndrome (BCS) is a rare clinical entity characterized by post-sinusoidal portal hypertension caused by the obstruction to the hepatic vein outflow The diagnosis is suggested by hepatic scintigraphy and is usually confirmed by hepatic venography, inferior vena cavography and biopsy. The scintigraphic finding of BCS caused by the obstruction of main hepatic vein has been reported to consist typically of hypertrophy of the caudate lobe with increased radionuclide accumulation. Such a typical finding has been accounted for by the fact that the venous outflow from the caudate lobe is preserved when the main hepatic vein is obstructed. But usually, the hepatic venous outflow from the caudate lobe is also obstructed in BCS due to inferior vena caval obstruction. So hepatic scintigraphic findings of BCS due to inferior vena caval obstruction show different findings as compared with the BCS due to hepatic vein obstruction. We evaluate the hepatic scintigrams of the 13 cases of BCS due to inferior vena caval obstruction and review the literatures. The results are as follows : 1) We cannot observe the caudate lobe hypertrophy with increased uptake, which is known as a classic finding in BCS due to hepatic vein obstruction. 2) The most prominent hepatic scintigraphic findings of BCS are nonhomogenous uptake in the liver with extrahepatic uptake in the all cases. 3) We can see cold areas at the superior aspect of right hepatic lobe in 7 cases (54%). This is a useful finding suggesting BCS due to inferior vena caval obstruction.

Congenital interruption of the inferior vena cava (IVC) can lead to secondary hepatic congestion, portal hypertension, and liver cirrhosis. A 49-year-old woman was admitted to the gynecology department with symptoms of menorrhalgia, known uterine myoma, and anemia. Abdominal computed tomography (CT) and venography performed at our hospital revealed congenital interruption of the IVC. The patient underwent retrohepatic cavoatrial bypass surgery with a polytetrafluoroethylene (PTFE) 16-mm ringed graft via posterolateral thoracotomy, and recovered without major complications. A retroperitoneal approach via posterolateral thoracotomy provides appropriate visualization during dorsal cavoatrial bypass in treating patients with congenital interruption of IVC.

The hot spot on liver scan was demonstrated by many authors in various conditions such as SVC obstruction, Budd-Chiari syndrome, liver abscess, hemangioma of liver, hepatic venoocclusive diseases, IVC obstruction, and tricuspid insufficiency. And the appearance of hot spot in SVC obstruction is due to unsual collateral circulation. But there was no report of this hots pot on liver scan in our country. We have recently observed one patient with SVC obstruction who shows well-defined area of increased radioactivity between right and left lobe of liver on liver scan using $^{99m}Tc-tin$ colloid, and demonstrated collateral circulations with RI venography using $^{99m}Tc-O_4$. The injection site of radiocolloid was left antecubital vein. This hot spot did not appear when the radiocolloid was injected into right leg vein. We report here this hot spot on liver scan in SVC obstruction with review of some liter atures.
