CFD analysis is the method used to assess rupture risk of cerebral aneurysm.We tried to assess rupture risk of pancreaticoduodenal aneurysm before and after resection of median arcuate ligament by CFD analysis.

Wall shear stress(WSS),one of the most important parameters of CFD analysis,is the frictional force against vessel wall.Many research show that low WSS increases rupture risk of cerebral aneurysm.In our case,WSS of pancreaticoduodenal aneurysm rised within normal range after the resection,which suggest the reduction of risk of aneurysm rupture.
