- W3103453879 abstract "To assess the clinical application of preoperative retrograde portal venography for children with cavernous transformation of the portal vein (CTPV).The clinical data of 8 cases of CTPV admitted in the Children's Hospital of Zhejiang University from January 2018 to September 2019 were retrospectively analyzed. Preoperative retrograde portography was performed to determine the corresponding vascular morphology and size of portal vein system. If the retrograde portography showed that the left branch of the shadow portal vein was unobstructed and its diameter was greater than 3 mm, Rex shunt would be performed after anatomic exploration of Rex recess; if retrograde portography showed that the diameter of left portal vein was less than 3 mm, but the diameter of left renal vein dissected during shunt operation was greater than 5 mm, Warren operation was selected. The patients were followed up for 1, 3 and 6 months after discharge, and then were followed up every 6 months.Retrograde portal venography was successfully performed in 8 child patients.The anatomical position and size of main portal vein and its left and right branches, left renal vein and other important vessels were determined. Among them, there was the well-developed left and right branches of portal vein in 4 child patients, in which the left and right branches of portal vein converged together, but did not communicate with the main portal vein. In addition, the left branch diameter of the portal vein was greater than 3 mm, and the anatomical exploration results during shunt were consistent with it, so Rex shunt was performed. In the other 4 cases, the left branch diameter of the portal vein was small (less than 3 mm) in 3 cases, and the right branch was not clearly developed. Moreover, the left branch of the portal vein was poorly developed and almost occluded in 1 case. However, the left renal vein in these 4 child patients was well developed, the blood flow was unobstructed and the diameter was greater than 5 mm, so Warren operation was performed. Seven patients recovered well after the operation, and the other one had digestive tract rudimentary one year after operation, and the condition was stable after conservative treatment.The preoperative retrograde portal venography can be used to evaluate the portal vein system in children with CTPV, which provides important clinical basis for making appropriate treatment plan before surgery." @default.
