目的 探讨DebakeyIII型主动脉夹层进行腔内隔绝术 (EVE)后CT评估的方法及价值。 方法 5 1例De bakeyIII型主动脉夹层患者接受了EVE手术治疗。主要检查内容为移植物的形态、位置 ;移植物内的血流通畅度 ;有无内漏及夹层变化情况。结果 术后近期CT所见 :1例术后 7天CTA检查发现移植物中段少量内漏。 4例于术后 7天发现假腔血栓化不彻底 ,有远端血液反流入假腔。 1例移植物失去正常形态 ,但血流通畅 ,未处理。其余均未发现真腔外异常血流影像。结论 主动脉夹层EVE术后CT评估具有图像重建方式多样、提供的信息量大、可准确测量、图像直观易理解、成像清晰、可观察周围组织、易检出并发症等优点 ,应作为首选的术后评估方法。
Objective To explore the method and value of CT evaluation of Debakey III aortic dissection after endovascular graft exclusion (EVE). Methods Fifteen patients with De bakey III aortic dissection underwent EVE surgery. The main inspection contents are the morphology and location of the graft, the degree of patency of the blood flow in the graft, the internal leakage and the change of the dissection. Results Postoperative CT findings: a case of 7 days after CTA examination showed a small amount of endocardial leakage. 4 cases found false lumen thrombosis 7 days after surgery is not complete, there is distal blood reflux into the false lumen. One graft lost its normal morphology, but blood flow was unobstructed. The rest were not found outside the true cavity abnormal blood flow images. Conclusion CT evaluation of aortic dissection with EVE has the advantages of multiple image reconstruction methods, large amount of information provided, accurate measurement, intuitive and easy to understand images, clear imaging, observable surrounding tissues and easy detection of complications, which should be the first choice Postoperative evaluation method.
