BACKGROUND
The presence of perigraft air is a common finding in the immediate post-operative phase following abdominal aortic aneurysm repair whilst the later appearance of air, in association with elevated inflammatory markers, is regarded as being indicative of the serious complication of graft infection. What is not known is at what timepoint following surgery does the perigraft air become a significant finding.
CASE PRESENTATION
We report the case of a 71 year old man who underwent a computed tomography scan 15 days following repair of an abdominal aortic aneurysm because of the presence of unexplained pyrexia. The scan showed the presence of perigraft air and a small haematoma. The patient was managed conservatively and after 6 weeks the air and haematoma had resolved completely.
CONCLUSION
The presence of perigraft air in the early postoperative phase is probably a normal finding, is not associated with graft infection and can be managed non-operatively.
背景
移植血管周围出现气体是腹主动脉瘤修复术后即刻常见的表现，而术后晚期出现气体并伴有炎症标志物升高则被视为移植血管感染这一严重并发症的指征。目前尚不清楚术后哪个时间点移植血管周围气体成为显著表现。
病例报告
我们报告一例71岁男性患者，因不明原因发热在腹主动脉瘤修复术后15天接受了计算机断层扫描。扫描显示移植血管周围有气体及一小血肿。患者接受保守治疗，6周后气体和血肿完全消退。
结论
术后早期移植血管周围出现气体可能是正常表现，与移植血管感染无关，可采用非手术方式处理。
