目的:探讨肝癌术后定期直接门静脉造影的新方法及其在肝癌治疗中的临床意义。材料和方法:肝癌剖腹手术患者30例,术中插管至门静脉主干,并将 IDDS 埋植于腹壁皮下,术后定期直接经 IDDS 推注泛影葡胺,观察门静脉显影情况并拍摄点片。结果:门静脉显影情况良好,Ⅱ级显影率19.1%、Ⅲ级51.4%、Ⅳ级29.4%。未见不良反应。结论:此新方法开辟了肝癌门静脉血流动力学研究的新途径,并有助于指导术后治疗。
Objective: To explore the new method of direct portal vein angiography after liver cancer operation and its clinical significance in the treatment of liver cancer. Materials and Methods: Thirty patients undergoing laparotomy were enrolled in the study. Thirty patients undergoing laparotomy were subjected to intraoperative cannulation to the main portal vein. IDDS was implanted subcutaneously in the abdomen. Postoperatively, IDDS was used to inject diatrizoate directly to the meglumine. The development of the portal vein was observed and photographed. RESULTS: The development of the portal vein was good, with grade II development rate of 19.1%, grade III 51.4%, and grade IV 29.4%. No adverse reactions were seen. Conclusion: This new method opens up new ways for the study of hepatic portal vein hemodynamics and helps guide postoperative treatment.
