Aorta diseases misdiagnosed as simple inferior limb thrombo-embolism in 9 cases / 中华普通外科杂志

ABSTRACT

Objective To analyze the causes of misdiagnosis of aorta diseases for simple inferior limb artery thrombo-embolism,and summarize the clinical experience. Methods Retrospective analysis was made on clinical data of 9 eases misdiagnosed aorta disease,including clinical manifestation,misdiagnosis,improper treatment and final definite diagnosis. Results All 9 cases were misdiagnosed as simple inferior limb thrombo-embolism at first.Three cases were treated with emergent thrombectomy using Fogarty catheter.The correct diagnosis Was achieved by 3-dimensional CT angiography (3DCTA) after operation,and the eitiology of other 6 cases were also pmved as aortic disease by 3DCTA before operation.Among 5 cases of acute aorta dissection with iliac-femoral artery involved,2 cases abandoned surgery with one dying the next day and the other lost to follow-up after being discharged.The other 3 cases were treated with endovascular therapy successfully.One case of abdominal aorta anurysm with mural thrombosis defluxion were treated by aneurysm resection.The other 3 caBes of Leriche syndrome with acute aorta terminal filament thrombosis formation were cured by aortoiliac bypass.The limbs ischemia were improved in all cases without perioperative death.Conclusion Aorta diseases can sometimes lead to acute inferior limb ischemia,mimicking limb artery thrombo-embolism.Preoperative imaging especially 3 DCTA helps to establish correct preoperative diagnosis for a successful treatment.
