The use of percutaneous trans-splenic access (TSA) of the portal system has grown for the treatment of chronic portal vein occlusion, placement of stents in cases of portal vein stenosis, portal vein embolisation of the liver, embolisation of gastric varices, placement of porto-systemic shunts, and interventions after liver transplants.
The authors conclude that the use of percutaneous TSA access could be used for the treatment of many portal system abnormalities with high success and low complication rates.
