Abstract:
Objective To detect the changes of hemodynamics in patients with portal vein embolization (PVE) before surgery for hilar cholangiocarcinoma, and analyze the relationship between hemodynamics and liver hypertrophy. Methods The clinical data of 21 patients with hilar cholangiocarcinoma who were admitted to the Eastern Hepatobiliary Surgery Hospital from April 2008 to December 2009 were retrospectively analyzed.Relevant hemodynamic variables were detected and analyzed before and 3, 7, 14 days after PVE. Data were processed using Student t test or linear correlation analysis. Results The main portal vein pressure after PVE was (25.9 ± 4.1 ) cm H2O ( 1 cm H2O = 0.098 kPa), which was ( 3.5 ± 2.5 ) cm H2O higher than that before PVE [( 22.4 ± 4.1 ) cm H2O] ( t = - 6. 504, P ＜ 0.05 ). The blood flow velocity in the non-embolized branch of portal vein increased after PVE, and reached peak [(26 ±9)cm/s] at the seventh day after PVE. A positive correlation was found between the hypertrophic rate of the non-embolized lobes and the ratio of embolized lobes to total liver volume ( r = 0. 593, P ＜ 0. 05 ). Conclusion Greater scope of the embolized vascular bed of portal vein induces higher hypertrophic rate of non-embolized liver.
