摘要
目的 探讨多层螺旋CT研究Sp V和SMV血流在门静脉内和肝内的分布规律的研究。方法 本实验所选取的研究对象为我院从2013年2月~2014年6月接诊的125例患者,对患者的上腹部进行多层螺旋CT平扫和增强扫描,观察患者的门静脉主干（MPV）内Sp V和SMV的血流分布的情况。分别测量患者在平扫和增强检查后动脉期门静脉左支（LPV）和动脉期门静脉右支（RPV）、肝脏的左叶和肝脏的右叶的CT值,分析患者的门静脉内和肝脏内Sp V和SMV的血流的分布规律。结果 有81例（64.80%）患者的门静脉主干内Sp V和SMV血流的分布为分层分布（A组）,有32例（25.60%）患者为螺旋形分布（B组）,其余12例（9.60%）患者为紊乱分布（C组）;患者进行平扫时,门静脉内和肝内的左支与右支的血流分布无统计学意义（P〉0.05）;患者进行增强动脉扫描时,门静脉内和肝内的左支的血流分布显著高于右支的血流分布（P〈0.05）;其中有105例的患者的Sp V血液是先进入患者门静脉左支,然后再流向患肝脏的左叶,SMV血液是先进入患者门静脉右支,然后再流向患者肝脏的右叶。结论 患者的Sp V和SMV血流是以分层分布、螺旋形分布、紊乱分布三种分布形式存在于门静脉内和肝脏内,有多数患者的Sp V血液是通过患者门静脉左支进入患者肝脏的左叶,SMV血液是通过患者门静脉右支进入患者肝脏的右叶。
Objective To explore the regularities of distribution on Multislice spiral CT study SpV and SUV blood flow in the portal vein and liver. Methods 125 cases of admissions of patients cured in our hospital from February 2013 to June 2014 were selected as the research object.Multislice spiral CT scan and enhanced scan were used in the upper abdomen of patients,and the distribution of blood flow in SpV and SMV in patients with portal vein （MPV） was observed.The liver left lobe of the liver and of the right lobe of the CT values of patients were measured on unenhanced and enhanced inspection after left hepatic artery portal vein （LPV） and arterial portal vein right branch （RPV）.And then the distribution of blood flow of SpV and SMV in patients with portal vein and liver were analyzed. Results There were 81 cases （64.80%） of patients with stratified distribution of portal vein blood flow within SpV and SMV （A group）,and 32 cases （25.60%） of patients with a spiral-shaped distribution （B group）,and the remaining 12（9.60%） patients were disordered distribution （Cgroup）.When patients were plain,the distribution of blood flow in the portal vein intrahepatic left branch and the right branch were no significant difference （P 〉 0.05）.When patients were enhanced scan artery,portal vein and the left branch of the hepatic blood flow distribution were significantly higher blood flow distribution right branch （P 〈 0.05）.There were 105 cases of patients with SpV blood first entering the patient left portal vein,and then flowing to the left lobe of the liver patients,and SMV into the patient＆#39;s blood was fist entering the right portal vein,and then flowing to the right lobe of the liver of patients. Conclusion SpV and SMV blood flow of patients exist in the portal vein and liver by stratification distribution,spiral-shaped distribution, distribution of disorder present three forms of distributions.SpV blood of majority of patient is into the liver via the portal vein in patients wit
