Transjugular intrahepatic portosystemic shunt (TIPS) is an important therapeutic tool available to decrease portal vein pressure in patients with cirrhosis and portal hypertension. TIPS is associated with various complications, and fistula formation is an important one to be noted. We present an unusual and interesting case of a patient who developed right-sided heart failure 5 months after TIPS placement. Diagnostic workup revealed an uncommon fistula between the celiac artery trunk and portal vein that was successfully treated with angiography-guided embolization, resulting in clinical improvement.

Transjugular intrahepatic portosystemic shunt (TIPS) represents a very effective treatment of complications of portal hypertension. Established indications to TIPS in cirrhotic patients include portal hypertensive bleeding and refractory ascites. Over the years additional indications have been proposed, such as the treatment of vascular disease of the liver, hepatic hydrothorax, hepatorenal syndrome and bleeding from ectopic varices. Indications under evaluation include treatment of portal hypertension prior to major abdominal surgery and treatment of portal vein thrombosis. In spite of these advances, there are still uncertainties regarding the appropriate workup for patients to be scheduled for TIPS. Moreover, prevention and management of post-TIPS complications including hepatic encephalopathy and heart failure are still suboptimal. These issues are particularly relevant considering aging in TIPS candidates in Western countries. Correct selection of patients is mandatory to prevent complications which may eventually frustrate the good hemodynamic results and worsen the patient's quality of life or even life expectancy. The possible role of small diameter TIPS to prevent post-procedural complications is discussed.

In this review, we summarise the current knowledge on the indications and contraindications of transjugular intrahepatic portosystemic shunt (TIPS) placement for the treatment of the complications of portal hypertension in cirrhosis, specifically variceal haemorrhage and ascites. Moreover, we discuss the role of TIPS for the treatment of portal vein thrombosis (PVT) and the prevention of complications after extrahepatic surgery ('preoperative TIPS') in patients with cirrhosis. The position of TIPS in the treatment hierarchy depends on the clinical setting and on patient characteristics. In acute variceal haemorrhage, preemptive TIPS is indicated in patients at a high risk of failing standard therapy, that is those with a Child-Pugh score of 10-13 points or Child-Pugh B with active bleeding at endoscopy, although the survival benefit in the latter group still remains to be established. Non-preemptive TIPS is a second-line therapy for the prevention of recurrent variceal haemorrhage and for the treatment of ascites. Of note, TIPS may also improve sarcopenia. Contraindications to TIPS placement, independent of clinical setting, include very advanced disease (Child-Pugh >13 points), episodes of recurrent overt hepatic encephalopathy without an identifiable precipitating factor, heart failure, and pulmonary hypertension. In patients with PVT, TIPS placement not only controls complications of portal hypertension, but also promotes portal vein recanalisation. Although the severity of portal hypertension correlates with poor outcomes after extrahepatic surgery, there is no evidence to recommend preoperative TIPS placement.

Hereditary hemorrhagic telangiectasia is a rare autosomal dominant disease that can involve the liver. The presence of arteriohepatic venous shunts can lead to high output cardiac failure and biliary ischemia, whereas arterioportal venous shunts can result in portal hypertension. Cirrhosis and nodular regenerative hyperplasia are also reported in these patients. Management of these patients in the setting of symptomatic liver disease is challenging. Transarterial embolization and hepatic artery ligation are usually considered palliative options. In selected cases, orthotopic liver transplantation can cure both liver disease and heart failure.

[Editorial] Thoracic duct decompression (TDD) is an idea first proposed and applied as a novel therapeutic strategy by lymphologists in the 1960's. TDD is recently being reexamined and, in selected patients with portal hypertension from hepatic cirrhosis or with central venous hypertension from isolated right-sided heart failure, undertaken using advanced surgical and image-guided interventional radiologic approaches.

Hereditary hemorrhagic telangiectasia (HHT) is an autosomal dominant vascular disorder characterized by spontaneous epistaxis, telangiectasia, and visceral vascular malformations. Hepatic vascular malformations are common, though a minority are symptomatic. Symptoms are dependent on the severity and exact type of shunting caused by the hepatic malformation: Arteriosystemic shunting leads to manifestations of high output cardiac failure, and arterioportal shunting leads to portal hypertension. Radiologic imaging, including ultrasound, computed tomography (CT), and magnetic resonance imaging (MRI), is an important tool for assessing liver involvement. Doppler ultrasonography is the first-line screening modality for HHT-related liver disease, and it has a standardized scale. Imaging can determine whether shunting is principally to the hepatic vein or the portal vein, which can be a key determinant of patients' symptoms. Liver-related complications can be detected, including manifestations of portal hypertension, focal liver masses as well as ischemic cholangiopathy. Ultrasound and MRI also have the ability to quantify blood flow through the liver, which in the future may be used to determine prognosis and direct antiangiogenic therapy.

Congenital intrahepatic arterio-portal fistulae (cIAPF) are rare, high-flow vascular malformations that usually present with portal hypertension. They almost never cause heart failure, unless there is associated congenital heart disease or the ductus venosus in patent. We present an unusual case of IAPF in an 11-day-old boy, who presented with features of cardiac failure associated with increased N-terminal pro-brain natriuretic peptide (NT pro-BNP). The IAPF arose directly from the aorta, separated from the hepatic artery and divided to separately supply both left and right portal veins. The ductus venosus was occluded. The IAPF was treated with embolization of the aorto-portal fistula, accessed through a direct percutaneous puncture of the fistula. Embolization was associated with an immediate clinical improvement and a rapid and sustained normalization of the NT pro-BNP level. A similar re-presentation was noted and treated with repeat embolization. The child is well on follow-up. To our knowledge, this is the first case of cIAPF, which was presented with cardiac failure when the ductus venosus has closed and has been treated successfully with direct, percutaneous transhepatic embolization of the fistula, twice. Serial clinical follow-up and ultrasonographical examinations have proven to be an effective strategy to detect recurrent fistulae.
