【摘要】:目的分析布-加综合征患者首次确诊时副肝静脉的代偿扩张情况,并对其代偿扩张可能的影响因素及其临床意义进行探讨。方法1.回顾性分析我院2015年1月至2016年12月78例布-加综合征患者的临床资料,应用彩色多普勒超声评估患者首次确诊时副肝静脉的支数及其直径大小。根据彩超结果分为明显代偿扩张组(副肝静脉单支最大直径≥5mm或副肝静脉直径总和≥6mm,n=58)和无明显代偿扩张组(副肝静脉单支最大直径5mm且副肝静脉直径总和6mm,n=20),同时将检出的副肝静脉按其直径大小分为A类(直径≥5mm,n=96)和B类(直径5mm,n=28)。2.查阅患者的病历资料,分别记录分析两组患者的性别、年龄、疾病类型、主肝静脉梗阻程度、症状持续时间、PT、Child-Pugh分级、门静脉主干内径、门静脉入肝血流流速、副肝静脉长轴与下腔静脉近心段长轴夹角、血清VEGF水平、血清D-二聚体水平、血清纤维蛋白原水平。3.统计学分析采用SPSS 21.0,检验标准为α=0.05,对比分析明显代偿扩张组和无明显代偿扩张组患者的相关影响因素。结果1.78例布-加综合征患者有68例检出副肝静脉,检出率为87.18%(68/78),共检出124支副肝静脉(A类96支,B类28支),平均(1.59±0.87)支,直径为3~11mm,平均(6.27±1.97)mm。其中明显代偿扩张组58例,共检出114支副肝静脉(A类96支,B类18支),平均(1.97±0.62)支,直径为4~11mm,平均(6.50±1.87)mm;无明显代偿扩张组20例,共检出10支副肝静脉(均为B类),平均(0.50±0.51)支,直径为3~4.4mm,平均(3.58±0.58)mm。明显代偿扩张组患者症状持续时间为(0~480)个月,平均(105.61±135.65)个月;无明显代偿扩张组患者症状持续时间为(0.25~240)个月,平均(53.83±73.42)个月。2.明显代偿扩张组中以混合型为主(94.8%,55/58),无下腔静脉梗阻型,无明显代偿扩张组中也以混合型(75.0%,15/20)为主,有下腔静脉梗阻型(20.0%,4/20),差异具有统计学意义(P0.05);明显代偿扩张组主肝静脉梗阻程度以Ⅳ度(3支主肝静脉均梗阻)为主(89.7%,52/58),无明显代偿扩张组以Ⅲ度(任意1支主肝静脉通畅)为主(50.0%,10/20),差异具有统计学意义(Z=-5.378,P0.05);明显代偿扩张组血清VEGF水平显著低于无明显代偿扩张组(t=-7.437,p0.05)。两组患者的性别(χ2=0.027)、年龄(t=0.960)、Child-Pugh分级(Z=-0.564)、PT(t=-0.020)、血清D-二聚体水平(t=0.166)、血清纤维蛋白原水平(t=-1.562)、门静脉主干内径(t=1.586)、门静脉入肝血流流速(t=0.154)均无统计学差异(均p0.05)。A类副肝静脉长轴与下腔静脉近心段长轴夹角以钝角为主(60.4%,58/96);B类以锐角(46.4%,13/28)和近似直角(35.7%,10/28)为主,差异具有统计学意义(χ2=15.827,P0.05)。当样本为全部患者(78例)时,副肝静脉直径总和与主肝静脉梗阻程度呈正相关(r=0.657,P0.05),与血清VEGF水平呈负相关(r=-0.725,P0.05);主肝静脉梗阻程度与血清VEGF水平呈负相关(r=-0.445,P0.05)。当样本为剔除Ⅰ、Ⅱ度主肝静脉梗阻的剩余患者(74例)时,副肝静脉直径总和与主肝静脉梗阻程度呈正相关(r=0.592,P0.05),与血清VEGF水平呈负相关(r=-0.832,P0.05);主肝静脉梗阻程度和血清VEGF水平呈负相关(r=-0.539,P0.05)。当样本为剔除Ⅰ、Ⅱ度以及下腔静脉管腔通畅的Ⅲ、Ⅳ度主肝静脉梗阻的剩余患者(68例)时,副肝静脉直径总和与主肝静脉梗阻程度呈正相关(r=0.614,P0.05),与血清VEGF水平呈负相关(r=-0.834,P0.05);主肝静脉梗阻程度与血清VEGF水平呈负相关(r=-0.563,P0.05)。结论布-加综合征患者的副肝静脉多代偿性扩张,此变化与疾病类型(特别是主肝静脉梗阻程度)、血清VEGF水平有关,主肝静脉梗阻程度越高,副肝静脉的代偿扩张越明显;副肝静脉长轴与下腔静脉长轴夹角大小可能与其扩张程度有关。
[Abstract]:Objective to analyze the Budd accessory hepatic vein in patients with first diagnosed compensatory expansion and syndrome, and the compensatory expansion of the possible influence factors and its clinical significance were discussed. The 1. methods were retrospectively analyzed in our hospital from January 2015 to December 2016, 78 cases of Budd Chiari syndrome in patients with clinical data, the number and diameter of accessory hepatic vein application of color Doppler ultrasound in the evaluation of patients with first diagnosed. According to the results of color Doppler ultrasound was divided into compensatory dilatation group (accessory hepatic vein single largest diameter less than 5mm and accessory hepatic vein total diameter of more than 6mm, n=58) and no significant compensatory expansion of accessory hepatic vein group (single maximum diameter 5mm and accessory hepatic vein total diameter 6mm, n=20 at the same time,) the detected accessory hepatic veins according to their diameter divided into class A (larger than 5mm in diameter, n=96) and B (diameter 5mm, n=28).2. consult the patient's medical records, records of the two groups of patients with gender, age, disease. 鐥呯被鍨,
