Techniques include back-table reconstructions using Carrel or branch patches, end-to-end anastomoses, or grafting variant arteries to donor gastroduodenal or splenic artery stumps. When recipient arterial inflow is inadequate, alternatives like aortohepatic conduits or splenic artery inflow are employed, though with increased risk. In pediatric…
