摘  要:【摘要】目的研究肝硬化患者门静脉血栓形成(PVT)的相关危险因素。方法回顾性分析2009年1月至2011年12月确诊的294例肝硬化患者病历资料,依据多排螺旋CT或彩色超声检查结果诊断PVT,其中55例肝硬化合并PVT患者作为PVT组,239例肝硬化无血栓患者作为非PVT组。记录分析患者年龄、性别、肝硬化病因、Child—Pugh分级和评分、血常规、生物化学、凝血功能、血浆D-二聚体等实验室检查结果,以及门静脉主干内径、门静脉流速、脾脏厚度等。计量资料分析采用t检验。采用非条件Logistic回归模型筛选出相应的独立危险因素,绘制ROC曲线计算AUC,判断各指标的诊断价值。结果PVT组与非PVT组患者的WBC、Hb、TBil、肌酐、血清钠、PT、活化部分凝血活酶时间、纤维蛋白原、INR检测结果相似,差异均无统计学意义(P均〉O.05)。PVT组患者的PLT、白蛋白、血浆D二聚体水平、门静脉主干内径、门静脉流速、脾脏厚度、Child—Pugh评分与非PVT组比较,分别为(82.55±23.04)×109/L比(99.66±20.23)×109/L(t=-0.308,P=0.022),(30.53±2.32)g/L比(33.36±3.62)g/L(t=-2.117,P=0.036),(1.00±0.22)mg/I。比(0.77±0.15)mg/L(t=7.557,P=0.003),(15.11±1.32)mm比(13.40±1.43)mill(t=8.013,P=0.014),(13.51±1.51)cm/S比(15.16±1.60)cm/s(t=-6.979,P=0.036),(59.35±5.45)mm比(54.64±5.92)mm(t=1.9555,P=0.043),(11.73±2.01)分比(8.18±3.05)分(t=6.225,P=0.006),差异均有统计学意义。非条件Logistic回归模型分析结果显示PVT组血浆D-二聚体、Child—Pugh评分、门静脉主干内径、门静脉流速是肝硬化患者PVT独立危险因素(OR=13.420、10.237、8.534、0.151,P=0.001、0.014、0.019、0.025)。ROC曲线分析显示血浆D---聚体、ChilObjective To investigate the risk factors of portal vein thrombosis (PVT) in patients with liver cirrhosis. Methods From January 2009 to December 2011, the data of 294 hospitalized patients diagnosed as liver cirrhosis were retrospectively analyzed. PVT was diagnosed according to multislices spiral computed tomography or color doppler ultrasonography. Fifty-five patients with liver cirrhosis and PVT were in PVT group, 239 patients with liver cirrhosis however no PVT were in non PVT group. Age, gender, etiology of cirrhosis, Child Pugh grading and score, blood routine examination, blood chemistries, blood coagulation function, D-dimer, main portal vein (MPV) internal diameter, portal vein velocity (PVV) and thickness of spleen were recorded and analyzed. The measurement data were analyzed by t test. Unconditional Logistic regression model was performed to screen corresponding risk factors. Area under curve (AUC) was calculated according evaluate the diagnostic value of each index. Results to receiver operator characteristic (ROC) curve to The results of white blood cell, hemoglobin, total bilirubin, creatinine, serum natrium, prothrombin time, activated partial prothrombin time, librinogen and international normalized ratio of PVT group were similar with those of non-PVT group and there were no statistically significant differences (all P〉 0. 05). Compared with those of non-PVT group, the differences in platelet count, albumin level, the level of D-dimer, MPV internal diameter, PVV, spleen thickness, and Child-Pugh score of PVT group were statistically significant ((82.55±23.04) × 109/L vs (99.66±20.23)× 109/L(t=--0. 308,P=0. 022), (30. 53±2. 32) g/L vs (33. 36±3. 62) g/L(t= --2.117,P=0.036), (1.00±0.22) mg/L vs (0.77±0.15) mg/L(t=7.557,P=0.003), (15. 11±1.32) mm vs (13.40±1.43) mm(t=8. 013,P=0. 014), (13.51±1.51) cm/s vs (15. 16±1.60) cm/s (t=--6. 979,P=0. 036), (59.35±5.45) mm vs (54.64±5.92) mm(t=l.
