肝门、肝、下腔静脉MSCT共同成像的临床观察与对策

目的：探讨多排螺旋CT（MSCT）行肝门静脉、肝静脉、下腔静脉共同戍像成功的护理及操作技术要点。方法：应用双高压注射器在右肘前静脉及下肢浅静脉双通路按造影要求注入造影刑，利用自动示踪软件行肝门静脉系统分期扫描，分别评价肝门静脉、肝静脉及下腔静脉的显示率及程度。结果：双通路注入造影剂护理技术的准确操作，而且术前、术中、术后三期护理到位的患者肝门静脉系统显示率达100％，肝门静脉、肝静脉、下腔静脉显示评分为2．70～2．90。结论：护理技术是确保肝门静脉、肝静脉、下腔静脉共同成像成功的关键。在右肘部静脉及下肢浅静脉注入造影荆行MSCT动脉期扫描完成后，延时20．1±5．54秒行肝门静脉系统造影检查，共同成像效果良好。

Nursing study on hepatic portal,hepatic,inferior vena cava MSCT common imaging

Objective： To investigate nursing operating techniques of MSCT hepatic portal vein, hepatic vein, inferior vena eava success of the common imaging. Methods： Inject contrast medium to the right elbow vein and lower extremity venous from two high pressure injections under the requirement of angiography, under the control of the medium auto-tracing software to scan portal system by stages. Evaluate the show rate and degree of hepatic portal vein, hepatic vein and inferior vena cava respectively. Results： Accurate operation of nursing technical and targeting nursing by three stages： preoperative, mid-operative, post-operative are the key points of bi-pass angiography technical. The show rate of hepatic portal vein is 100%, the average score of show rate to the hepatic vein and inferior vena cava is 2.70--2.90. Conclusions： Nursing technical is he key points of angiography technical of portal system. Scan arterial phase by MSCT after injecting contrast medium to the right elbow vein and lower extremity venous, then scan portal system with 20.1 4-5.54s delay, we will get better effect of common imaging.
