Background and purpose: Fever is a common symptom of acute aortic dissection. The beginning time and duration of fever after percutaneous endovascular stent-graft in patients with aortic dissection is not well known. The present study was undertaken to investigate the characteristics of fever after percutaneous endovascular stent-graft in patients with type B aortic dissection.
Methods and results: In this retrospective study the data of a total of 64 patients with type B acute aortic dissection undergoing percutaneous endovascular stent-graft were collected and analyzed. In total, 55 patients (85.9%) had fever after stent-graft. The time of fever onset was during the initial 2 days after interventional procedure (92.7%), and the duration of fever of most patients was not beyond 7 days after stent implantation. The fever before stent implantation was associated with the beginning time of fever after stent implantation, but not with the duration of fever.
Conclusion: The results of this study could provide important reference information for the evaluation of fever before and after interventional treatment in patients with acute aortic dissection.
