Retrospective evaluation of postoperative long-term results after surgery of inflammatory aortic aneurysms (IAAA) with computed tomography (CT). Findings in CT were analysed with particular attention to the development of inflammatory tissue adjacent to the aneurysm site.
Of 2101 patients operated on an aortic aneurysm 5.4% (114 patients) presented typical intraoperative features of inflammatory aortic aneurysms. 54 of these 114 patients (47%) were examined via computed tomography pre- and post-operatively. On an average the follow-up-study was performed 2.5 years postoperatively.
All follow-up-studies revealed a correct location of the aortic prostheses. In 85.1% of the cases there was either no or negligible persisting inflammatory tissue with a diameter of less than 2 mm. 10.6% of the patients demonstrated remaining but reduced inflammatory tissue. In 4.3% of the cases the extent of the inflammatory tissue had not changed. Aneurysms of the anastomoses (n = 4), morphologic renal changes (n = 7) and an aorto-enteric fistula were demonstrated by CT as postoperative complications.
In evaluating recurrence of the aneurysm and possible complications as well as the development of the inflammatory tissue, postoperatively performed computed tomography proved a reliable diagnostic method.
采用计算机断层扫描（CT）对炎性主动脉瘤（IAAA）手术后的长期结果进行回顾性评估。分析CT检查结果，尤其关注动脉瘤部位附近炎性组织的发展情况。
在2101例行主动脉瘤手术的患者中，5.4%（114例）表现出炎性主动脉瘤的典型术中特征。这114例患者中的54例（47%）在术前和术后均接受了计算机断层扫描检查。随访研究平均在术后2.5年进行。
所有随访研究均显示主动脉假体位置正确。在85.1%的病例中，要么没有持续存在的炎性组织，要么存在直径小于2mm的可忽略不计的炎性组织。10.6%的患者显示仍有炎性组织，但有所减少。在4.3%的病例中，炎性组织范围未发生变化。CT显示吻合口动脉瘤（n = 4）、形态学上的肾脏改变（n = 7）和主动脉肠瘘为术后并发症。
在评估动脉瘤复发、可能的并发症以及炎性组织的发展情况时，术后计算机断层扫描被证明是一种可靠的诊断方法。
