Aim:In order to study the influence of partial splenic embolization (PSE) on the segmental blood flow volume (BFV) of the portal vein (PV) in patients with cirrhosis,We determined BFV in different segments of PV before and after PSE with color Doppler flow imaging. Patients and methods:With color Doppler flow imaging,the segmental BFV of PV were determined in 28 patients with cirrhosis 1 week before and 2~3 weeks after PSE.The vein observed included splenic portal vein (SPV),superior mesenteric vein (SMV),main portal vein (MPV),left portal vein (LPV), and right portal vein (RPV).The material used for splenic embolization was the small pieces of gelfoam.The area of the splenic embolization for each patient was about 60%~70%. Results:After PSE,BFV of different sites of PV decreased,especially in SPV and MPV.BFV of them decreased by 69.7%( P 0.01) and 42.6%( P 0.05),respectively.While BFV of right sided PV (LPV+RPV) did not change.Before PSE、BFV of the left-sided PV (SPV+SMV) was markedly higher than that in MPV or in right sided PV.The differences between the left sided PV and MPV or the right sided PV were 1283.17±864.10 ml/min and 1186.36±649.54 ml/min,respectively.After PSE these differences significantly decreased 463.53±281.15 ml/min( P 0.02) and 96.36±50.42 ml/min ( P 0.0001) respectively. Conclusions:In patients with cirrhosis,although PSE may markedly diminish BFV of PV,BFV did not decrease too much to nourisn the hepatic cells.The differences of BFV betwwen left sided PV and MPV or right sided PV may be the main sources of the portal system shunts,which are significantly lowered by PSE.
