Abstract
AIM: To investigate the role of 64-slice computed tomography (CT) in portal vein cavernous transformation to determine surgical strategy.
METHODS: The site of lesions and extent of collateral circulation in 12 pediatric cases of cavernous transformation of the portal vein with surgical treatment were analyzed.
RESULTS: Eleven of 12 children had esophageal varices and were treated with lower esophageal and gastric devascularization and splenectomy, and the other case was only treated with splenectomy. There were eight cases with spontaneous spleen/stomach-renal shunt, four with Retzius vein opening, which was reserved during surgery. Three cases of lesions involving the intrahepatic portal vein (PV) were treated with living donor liver transplantation. One patient died from PV thrombosis after liver transplantation, and the rest had no significant complications.
CONCLUSION: The PV, its branches and collateral circulation were clearly seen by 64-slice spiral CT angiography, which helped with preoperative surgical planning.
