摘要: 目的 基于超声造影定量参数、超声血流参数构建肝硬化并发门静脉血栓的诊断模型,并进行验证。方法 选择2019年4月至2023年7月收治的97例肝硬化并发门静脉血栓患者为研究组,另选择同时间段收治的56例肝硬化未并发门静脉血栓患者为对照组。记录患者超声造影定量参数[峰值强度、达峰时间、曲线下面积(AUC)]与超声血流参数[门静脉内径(PVD)、门静脉流速(PVV)],分析肝硬化并发门静脉血栓的影响因素。构建并验证肝硬化并发门静脉血栓的诊断模型。结果 研究组AUC、峰值强度、PVD分别为(2147.85±372.41)dB/s、(16.33±4.29)dB、(16.83±4.67)mm,高于对照组的(1259.34±196.25)dB/s、(11.06±3.10)dB、(12.26±3.35)mm,差异有统计学意义(P<0.05);研究组达峰时间、PVV分别为(47.19±6.58)s、(10.69±2.43)cm/s,低于对照组的(79.23±10.17)s、(14.98±3.65)cm/s,差异有统计学意义(P<0.05)。研究组天冬氨酸氨基转移酶、活化部分凝血活酶时间(APTT)、丙氨酸氨基转移酶分别为(27.15±4.38)s、(29.48±4.71)U/L,低于对照组的(30.24±5.66)s、(42.53±5.89)U/L,差异有统计学意义(P<0.05);研究组D-二聚体为(3.19±0.57)μg/mL,高于对照组的(1.46±0.93)μg/mL差异有统计学意义(P<0.05)。峰值强度(OR=5.135,95% CI:2.257~11.680)、AUC(OR=4.540,95% CI:1.996~10.328)、PVD(OR=5.801,95% CI:2.550~13.196)、达峰时间(OR=4.242,95% CI:1.865~9.649)、PVV(OR=4.513,95% CI:1.984~10.267)、APTT(OR=0.237,95% CI:0.104~0.540)为肝硬化并发门静脉血栓的影响因素(P<0.05)。列线图模型诊断肝硬化并发门静脉血栓的灵敏度为89.69%(95% CI:73.41%~94.15%),特异度为91.07%(95% CI:74.28%~96.43%),AUC为0.905(95% CI:0.882~0.963)。结论 基于超声造影定量参数(AUC、峰值强度、达峰时间)、超声血流参数(PVD、PVV)构建肝硬化并发门静脉血栓的列线图诊断模型有助于早期筛查肝硬化并发门静脉血栓风险。

Abstract: Objective To establish and verify a diagnostic model of hepatic cirrhosis complicated with portal vein thrombosis based on quantitative parameters of contrast-enhanced ultrasound (CEUS) and ultrasonic flow parameters. Methods Ninety-seven cirrhotic patients complicated with portal vein thrombosis admitted to the hospital from April 2019 to July 2023 were selected as the research group. Fifty-six cirrhotic patients without portal vein thrombosis admitted during the same time period were selected as the control group. All patients underwent ultrasound examination, and the quantitative parameters of contra-enhanced ultrasound [peak intensity, peak time and area under curve (AUC)] and ultrasonic blood flow parameters [portal vein diameter (PVD) and portal vein flow velocity (PVV) ] were recorded. The influencing factors of cirrhosis complicated with portal vein thrombosis was analyzed. The diagnostic model of cirrhosis complicated with portal vein thrombosis was constructed and validated. Results The values of AUC, peak intensity, and PVD in the research group were (2147.85±372.41) dB/s, (16.33±4.29) dB, and (16.83±4.67) mm, respectively, which were significantly higher than those of (1259.34±196.25) dB/s, (11.06±3.10) dB, and (12.26±3.35) mm in the control group (P<0.05). The time to peak and PVV in the research group were (47.19±6.58) s and (10.69±2.43) cm/s, respectively, which were significantly lower than those of (79.23±10.17) s and (14.98±3.65) cm/s in the control group (P<0.05). The values of aspartate aminotransferase, activated partial thromboplastin time (APTT), and alanine aminotransferase in the research group were 21.07±3.45 U/L, (27.15±4.38) s, and (29.48±4.71) U/L, respectively, which were significantly lower than those of 27.84±4.90 U/L, (30.24±5.66) s and (42.53±5.89) U/L in the control group (P<0.05). The D-dimer level in the research group was (3.19±0.57) mg/mL, which was significantly higher than that of (1.46±0.93) mg/mL in the control group (P<0.05). The Peak intensity (OR=5.135, 95%CI: 2.257~11.680), AUC (OR=4.540, 95%CI: 1.996~10.328), PVD (OR=5.801, 95%CI: 2.550~13.196), time to peak (OR=4.242, 95%CI: 1.865~9.649), PVV (OR=4.513, 95%CI: 1.984~10.267), and APTT (OR=0.237, 95%CI: 0.104~0.540) were identified as influencing factors for portal vein thrombosis in liver cirrhosis (P<0.05).The sensitivity of the nomogram model in the diagnosis of portal vein thrombosis was 89.69% (95%CI: 73.41%~94.15%), the specificity was 91.07% (95%CI: 74.28%~96.43%), and the AUC was 0.905 (95%CI: 0.882~0.963). Conclusion The diagnostic model of liver cirrhosis complicated with portal vein thrombosis which was constructed based on quantitative parameters (AUC, peak intensity, peak time) and ultrasonic blood flow parameters (PVD, PVV) is helpful for early screening of the risk patients.
