Abstract:
Objective To research the change of the portal venous pressure after the stents implanted into portal vein in HCC.Methods Twelve HCC patients receiving portal venous stem embolization were included in this study.The portal venous pressures were recorded before varices embolized(P1),after embolized(P2)and after stents implanted(P3),respectively.Four groups were formed according to the pressures within portal vein stem(PV),portal vein branch without tumor invasion(PVB),splenic vein(SV) and superior mesenteric vein(SMV).Results In PV group,P1 was(45:17?2.25)cm H20,and P2 was (48.33?2.20)cm H_2O,P＜0.05,P3 was(39.33?2.44)em H_2O,thus P＜0.05 in comparing with P2.for PVB group,P1 was(38.08?2.97)cm H_2O,and P2 was(38.83?2.94)cm H_2O,P＞0.05,P3 was(37.41?2.37)cm H_2O,comparing with P2,P＞0.05.In SV group,P1 was(44.67?2.13)cm H_2O,and P2 was(48.17?2.20)cm H_2O,P＜0.05,P3 was(41.67?2.20)cm H_2O,comparing with P2,P＜0.05.Finally,the SMV group,P1 was(45.25?2.21 )cm H_2O,P2 was(48.42?2.19)cm H_2O,P＜0.05,P3 was(41.25?2.24)cm H_2O, in comparison with P2,P＜0.05.Conclusions In portal vein stem embolization,portal venous pressure would be higher after varices embolized,but lower after stents placement.
