Abstract
We evaluated 22 patients who had been diagnosed with primary aldosteronism (PA) and undergone adrenal venous sampling (AVS) in our hospital. Blood sampling was technically successful in all patients and, in terms of results, endocrinologically successful in 20 and unsuccessful in 2. We achieved a success rate of over 90% by preoperatively confirming the vascular anatomy by MDCT, selecting a catheter suitable for insertion into the right adrenal vein, and using an extension tube for children at the time of sampling. Of the 14 patients diagnosed with aldosterone producing adenoma (APA) by AVS, 7 underwent adrenal adenomectomy, and achieved improvement in blood pressure and biochemical test results. Thus, AVS is useful for the diagnosis and treatment planning of PA, and the demand for it will grow in the future.

Abstract
A79-year-old man having anomalous behavior was admitted to our hospital with hyperammonemia. Abdominal CT showed a large, tortuous shunt vessel between the superior mesenteric vein and inferior vena cava. Transcatheter embolization was selected because of his age. Embolization therapy was successfully performed with coils. After embolization therapy, hyperammonemia and symptoms improved, probably due to increase of portal blood flow that was shown on CT images.

Key words
・ Non-hepatocirrhosis

Abstract
We report a case of successful transjugular intrahepatic portosytemic shunt（TIPS）creation using the gun-sight approach. A male patient in his early fifties with severe liver cirrhosis and hepatic hydrothorax had been treated for recurrent bleeding from esophageal varices. He was referred to our department for TIPS creation. The portal vein was cranially located and lay in the same plane as the hepatic veins on CT images. Therefore we thought that it would be difficult to create TIPS using the standard TIPS creation technique. We created the portosystemic shunt using the gun-sight approach reported by Haskal et al. We used 2 loop snares to target the portal vein and middle hepatic vein. After the gun-sight view of overlapping loops was obtained by turning the image intensifier, a Chiba needle was introduced percutaneously into the portal vein and advanced to the middle hepatic vein through the snares. The wire through the needle was then caught by the snare loop of the middle hepatic vein and pulled out from the transjugular sheath. The rest of the procedures were completed in a standard fashion. The portosystemic shunt procedures were successful without complications. We think that the portosystemic shunt creation using the gun-sight approach is a good alternative when a standard TIPS creation is difficult or impossible.
