| 目的 探讨高原藏族肝棘球蚴病患者右心结构和功能的超声心动图特征。方法 随机选取经超声诊断为肝棘球蚴病的藏族患者113例，其中多房棘球蚴组（AE组）62例，细粒棘球蚴组（CE组）51例，另选同期生活于该地区且经超声检查未发现肝脏病变的藏族居民49例为对照组(C)。均行常规超声心动图检查，测量右心结构和功能相关参数，统计肺动脉压力增高比率。结果 AE组和CE组右室前后径（RV）、右室横径（RVTD）、肺动脉前向血流速度（PV）、肺动脉前向血流压差（PVG）均低于对照组，差异均有统计学意义（均P＜0.05），但AE组与CE组比较差异无统计学意义；CE组舒张早期三尖瓣血流速度/三尖瓣环运动速度(E/e)高于对照组，差异有统计学意义（P＜0.05）；AE组和CE组三尖瓣环收缩期位移(TAPSE)均低于对照组，差异均有统计学意义（均P＜0.05）；三组间肺动脉压力增高比率分别为AE:38%, CE:35% 及C:31%，差异无统计学意义。结论 应用超声心动图检出藏族肝棘球蚴病患者右室缩小和右心舒缩功能受损。 |

| Abstract: |
| Objective To explore the echocardiographic characteristics of right heart in tibetan patients with hepatic echinococcosis at Tibetan plateau. Methods Randomly selected 113 tibetan patients with hepatic echinococcosis which diagnosed by ultrasound scan，including 62 cases of alveolar echinococcosis（AE），51 cases of cystic echinococcosis（CE），and 49 tibetan residents living in same area as control group（C）.Routinely measured echocardiographic parameters of right heart，calculated the rate of increased pulmonary arterial pressure. Results hepatic echinococcosis usually present a solitary lesion and can easily involve the right liver. The overall distribution in right ventricular anteroposterior diameter（RV），right ventricular transverse diameter（RVTD），pulmonary artery forward flow velocity（PV） and pulmonary artery forward flow pressure（PVG） were different among three groups，and the AE group and the CE group were significantly lower than that in control group（P＜0.05），but there was no significant difference between the AE group and the CE group；The overall distribution in E/e ratio and TAPSE were different among three groups，and the E/e ratio in CE group was significantly higher than that of controls（P＜0.05）；the TAPSE in AE group and CE group were significantly lower than that in control group （P＜0.05）；There was no significant difference in the rate of increased pulmonary arterial pressure among three groups, specifically, AE: 38%, CE : 35%, and C: 31% respectively. Conclusion Tibetan patients with hepatic echinococcosis present a much thinner and smaller right ventricle as well as an impaired right ventricular function than that of controls. |
