Percutaneous transhepatic stenting by Wallstents of portal vein and bile duct stenoses caused by immunoblastic sarcoma in a liver transplantation.

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.

Pancreatic pseudocyst in a gastrectomized patient: treatment with internalized endoprosthesis.

Direct percutaneous drainage of pancreatic pseudocysts in communication with the duct of Wirsung can lead to pancreaticocutaneous fistula. These patients are safely treated with the percutaneous transgastric approach. In a gastrectomized patient who developed a pseudocyst, we percutaneously placed in internal endoprosthesis from the duct of Wirsung to the afferent loop and gastric pouch.

The open-ended guidewire as superselective catheter for intraarterial chemotherapy: experience in 190 procedures.

With intraarterial infusion, high levels of chemotherapeutic agents can be achieved in the tumoral area. We present our experience with open-ended guidewire (OEGW) associated with steerable guidewires (SGW) as superselective catheters for intraarterial chemotherapeutic infusion and embolization. This technique was used successfully in 62 patients (190 procedures) over 15 months.
