Abstract

Background: Imaging of the portal vein prior to puncture for TIPS is essential. Purpose: With this study, we examined a modified retrograde portography with regard to the reliable representation of the portal vein. Material and Methods: Prospective evaluation of 65 TIPS interventions with regard to the delimitation of the portal vein and the exact parameters of retrograde portography such as catheter diameter and contrast medium volume per injection. Results: Retrograde portographies with a large-lumen catheter (10 F) and a large contrast medium volume (40 mL) were performed in 35/63 patients with significantly better delineation of the portal vein than when using 5 F catheters with 10 mL contrast medium. Conclusion: The so-called high volume retrograde portography leads to better delimitation of the portal vein during TIPS application.

高容量逆行门静脉造影，以便在TIPS手术中更好地识别门静脉。

背景:门静脉造影在TIPS穿刺前是必要的。目的:在这项研究中，我们检查了一种改良的逆行门静脉造影，以可靠地表示门静脉。材料与方法:65项TIPS干预措施的前瞻性评价，涉及门静脉的划分和逆行门静脉造影的确切参数，如导管直径和每次注射造影剂体积。结果:35/63例患者行大腔导管(10f)和大造影剂体积(40ml)逆行门静脉造影，门静脉的描绘明显优于使用5f导管和10ml造影剂。结论:在应用TIPS时，所谓的高容量逆行门静脉造影可以更好地划分门静脉。
