Imaging-guided interventions modulating portal venous flow: Evidence and controversies
2021
Portal hypertension is defined by an increase in the portosystemic venous gradient. In most cases, increased resistance to portal blood flow is the initial cause of elevated portal pressure. More than 90% of cases of portal hypertension are estimated to be due to advanced chronic liver disease or cirrhosis. Transjugular intrahepatic portosystemic shunts, a non-pharmacological treatment for portal hypertension, involve the placement of a stent between the portal vein and the hepatic vein or inferior vena cava which helps bypass hepatic resistance. Portal hypertension may also be a result of extrahepatic portal vein thrombosis or compression. In these cases, percutaneous portal vein recanalis…
Chirurgische Therapie von Lebermetastasen kolorektaler Karzinome
2003
Resection is the only curative treatment of colorectal liver metastases proofed by a long-term follow-up. The operation is indicated if the metastases are completely removable with sufficient liver parenchyma remaining after resection and if the patient is fit for surgery. The resection is not indicated in cases with non resectable extrahepatic tumours and lymph node metastases distal the hepatoduodenal ligament. The postoperative mortality amounts to about 5 % and the 5-year-survival-rates range between 20 and 40 % depending on the selection of patients. Aims of new concepts of operative therapy are the improvement of resectability by preoperative portal vein embolization, the resection co…
