Purpose: To analyze the results obtained with percutaneous therapeutic procedures in patients with Budd-Chiari syndrome (BCHS).Methods: Between August 1991 and April 1993, seven patients with BCHS were treated in our hospital. Three presented with a congenital web; in another three cases the hepatic veins and/or the inferior vena cava (IVC) were compromised after major hepatic surgery; one patient presented with a severe stenosis of the intrahepatic IVC due to hepatomegaly.Results: One of the patients with congenital web has required several new dilatations due to restenosis; one patient required a transjugular intrahepatic portosystemic shunt procedure while awaiting a liver transplantation. The two postsurgical patients with stenosed hepatic veins did not require any new procedure after the placement of metallic endoprostheses. However, the patient with liver transplantation presented IVC restenosis after balloon angioplasty that required the deployment of metallic endoprostheses. In the patient with hepatomegaly a self-expandable prosthesis was placed in the intrahepatic portion of the IVC before (4 months) a liver transplantation.Conclusion: Interventional therapeutic techniques offer a wide variety of possibilities for the treatment of patients with BCHS. For IVC stenoses, the results obtained with balloon angioplasty are at least as good as those obtained with surgery. [ABSTRACT FROM AUTHOR]

Percutaneous embolization of large portosystemic collaterals was performed in three patients following placement of a transjugular intrahepatic portosystemic shunt in order to improve hepatopetal portal flow. Improved hepatic portal perfusion was achieved in these cases, thereby theoretically reducing the risk of chronic hepatic encephalopathy. [ABSTRACT FROM AUTHOR]

A case of an infected pseudocyst in the head of the pancreas is presented. Due to its small size and fistulization to the duodenum, a drainage catheter was placed through the fistulous tract from a distant transgastric approach. The fistula was balloon dilated to improve its emptying. Sixteen months later the patient remains asymptomatic with no recurrence of the pseudocyst. [ABSTRACT FROM AUTHOR]

Percutaneous transhepatic treatment of portal vein thrombosis after liver transplantation in a patient with a preexisting high volume spontaneous splenorenal shunt is presented. Local thrombolysis with urokinase and balloon angioplasty of the main portal vein stenosis were performed followed by shunt embolization to restore hepatopetal portal blood flow.

Posttransplant lymphoproliferative disorders are infrequent tumors related to chronic immunosuppressive therapy. We present a liver transplant recipient who developed such a tumor in the porta hepatis that provoked obstruction of the entire portal triad. Treatment consisted of systemic chemotherapy, percutaneous dilatation, and placement of Wallstent endoprostheses across both biliary and portal vein stenoses. The patient died 3 weeks later of pneumonia and sepsis. At necropsy, the tumor was completely necrosed and the prostheses in both the common bile duct and the portal vein were patent.

Portal vein (PV) thrombosis increases the risk of variceal bleeding in cirrhotic patients with portal hypertension. Its presence also complicates PV access during transjugular porto-caval shunt (TIPS) placement. We overcame this obstacle by using ultrasound (US) guidance for PV entry. Clot disruption by balloon catheters was then performed before placing the vascular endoprostheses for portal-venous shunting. We treated 3 cirrhotic patients in such fashion with good clinical results. Portal thrombi progressively disappeared after shunting due to both balloon disruption and the rise in portal blood flow velocity. [ABSTRACT FROM AUTHOR]

Purpose: The aim of the present study was to assess the efficacy of transjugular intrahepatic portosystemic shunts (TIPS) in 45 patients with cirrhosis during a mean follow-up of 7 months.Methods: Forty-five consecutive patients treated by TIPS and who had been followed for at least 6 months after TIPS or until death, were included. Mean follow-up was 7.2 +/- 5.0 months. Shunt patency was assessed at 1 week and 1 month, then every 3 months after the procedure by Doppler US and angiography whenever needed.Results: Thirty-six patients had been stented for refractory bleeding from ruptured esophagogastric varices. Of these, 8 patients (22%) rebled, 7 of whom were treated by a second shunt. Nine patients were treated for refractory ascites. Three patients had recurrent ascites due to shunt obstruction. All were treated by a second shunt which occluded in 2 patients. As a whole, 14 (31.1%) patients developed shunt obstruction within a mean of 120 +/- 136 days, 4 of whom remained asymptomatic. Other complications were septicemia by Staphylococcus aureus in 1 patient, transient encephalopathy in 9 patients, and disseminated intravascular coagulation in 1 patient.Conclusions: TIPS appears to be a relatively safe and effective technique in treating complications of portal hypertension in patients with cirrhosis. Shunt obstruction in 31% of our patients probably represents the most important limitation of this technique. [ABSTRACT FROM AUTHOR]

This paper presents the first description of a ruptured aneurysm of an aberrant right subclavian artery. CT clearly demonstrated the vascular malformation as well as the existence of a bilateral hemothorax. [ABSTRACT FROM AUTHOR]

A case of aortoesophageal fistula (AEF) is reported in a patient with esophageal bleeding resulting from ingestion of a foreign body. CT showed a saccular aneurysm in close proximity to the esophageal lumen at the level of the bleeding site. AEF has not previously been described on CT. [ABSTRACT FROM AUTHOR]
