摘要
目的:探讨肝小静脉闭塞症(hepatic veno-occlusive disease,HVOD)的超声影像特点及其诊断价值。材料和方法:回顾性分析6例HVOD患者11次灰阶及彩色多普勒超声图像,观察肝、肝静脉、门静脉、肝动脉、下腔静脉、胆囊、脾和腹水量。结果:6例HVOD治疗前均有不同程度的门静脉高压表现:灰阶超声示6例肝大,5例胆囊壁增厚呈双边影及腹水,4例脾大。彩色多普勒示门静脉血流速度减慢,1例出现反流,1例附脐静脉开放;4例患者肝静脉内径变窄,频谱呈门脉样;2例患者肝动脉阻力指数增高(>0.65)。经过系统的抗HVOD治疗后4例患者上述超声表现得到了不同程度的改善。结论:灰阶及彩色多普勒超声对HVOD具有重要的辅助诊断及鉴别诊断价值。
Purpose To investigated the ultrasound image characteristics of hepatic veno-occlusive disease （HVOD）. Materials and Methods From Sep 2005 to Sep 2008,6 patients were diagnosed of HVOD by Baltimore standard. The patients underwent grayscale and color Doppler ultrasound imaging for 11 times. The ultrasound features of liver,hepatic vein,portal vein,hepatic artery,inferior vena cava,gallbladder,spleen were observed and volume of ascites was assessed. Results Six patients had portal vein hypertension on different levels. On gray ultrasound images,6 had hepatomegaly,5 had gallbladder wall thickening and ascites,4 had splenomegaly. On color Doppler images,the velocity of portal vein flow decreased,one case had reflux and one had umbilical collateral vein opened. Four patients had hepatic vein stenosis showing portal vein spectrum. Two patients had artery resistance index increased （0.65）. After anti-HVOD treatment,4 cases had improved on ultrasound findings.Conclusion Gray-scale and color Doppler ultrasound may play an important role in diagnosis and differential diagnosis of HVOD.
