目的

分析肝硬化门静脉高压症(PH)脾切除术后门静脉系统血栓形成(PVST)的危险因素及预测效能。

方法

回顾性分析2011年11月至2018年12月中国医科大学附属盛京医院收治的行脾切除的278例肝硬化PH患者临床资料。

结果

患者术后PVST发生率为38.8%(108/278)。Logistic回归-ROC曲线模型显示,手术时间(AUC=0.651,95% CI:0.585~0.716)、术中输血浆量(AUC=0.615,95% CI:0.546~0.684)、术后脾静脉直径(AUC=0.665,95% CI:0.598~0.731)是影响脾切除术后PVST的独立危险因素,而术中输红细胞量(AUC=0.583,95% CI:0.514~0.651)和术后第7天TT水平(AUC=0.634,95% CI:0.568~0.699)是独立保护因素,以上指标对术后PVST都具有一定预测作用,且联合以上指标预测效能更高(AUC=0.783,95% CI:0.727~0.839)。

结论

对于肝硬化PH患者,应尽量缩短手术时间,通过围手术期适量输注红细胞和减少血浆输注预防PVST。综合考虑术后脾静脉直径和第7天TT水平因素有助于提高术后PVST的预测效能。

Objective

To analyze the risk factors of portal vein system thrombosis (PVST) after splenectomy in patients with cirrhosis of liver and portal hypertension (PH).

Methods

The clinical data of 278 patients with cirrhosis and PH who underwent splenectomy in Shengjing Hospital Affiliated to China Medical University from November 2011 to December 2018 were retrospectively analyzed.

Results

The formation rate of postoperative PVST was 38.8% (108/278). According to the Logistic regression-ROC curve model, operative time (AUC=0.651, 95% CI: 0.585-0.716), intraoperative plasma transfusion (AUC=0.615, 95% CI: 0.546-0.684), postoperative splenic vein diameter (AUC=0.665, 95% CI: 0.598-0.731) were independent risk factors for PVST formation after splenectomy. However, the intraoperative RBC transfusion (AUC=0.583, 95% CI: 0.514-0.651) and TT level on the 7 d after surgery(AUC=0.634, 95% CI: 0.568-0.699) were independent protective factors. All the above indexes had certain predictive effects on postoperative PVST formation, and the prediction efficiency of combining the above indexes was highe (AUC=0.783, 95% CI: 0.727-0.839).

Conclusions

For PH patients with liver cirrhosis, the operation time should be shortened as much as possible, and PVST may be prevented by appropriate transfusion of red blood cells and reduction of plasma transfusion during perioperative period. Combining the factors of splenic vein diameter and TT level on the 7th day is helpful to improve the prediction of PVST.
