An observational study in Aortic Dissection, Aortic Diseases and Aortic Aneurysm, Thoracic, sponsored by First Affiliated Hospital of Zhejiang University. Terminated at 1 site in China. Per ClinicalTrials.gov, last updated 2025-09-25.
Sponsored by First Affiliated Hospital of Zhejiang University · Observational
The infection rate of thoracic endovascular aortic repair (TEVAR) is unknown due to a lack of epidemiological data. The rate currently available comes from researches conducted decades ago, when open surgery was the standard of care. Because of the potentially fatal consequences of a stent graft infection in the thoracic aorta, the investigators tend to prescribe antibiotic prophylaxis for at least three days. In this study, the investigators are going to collect data on patients receiving TEVAR in the past five years and provide the following information: a. the infection rate (MAGIC classification), b. the rate of fever, c. the results of the lab tests, such as the WBC count and C-reaction protein. d. risk factors associated with infection and fever.
205 studies on the registry are indexed under Aortic Dissection; 73 are open to participants now.
This study's enrollment of 457 is above the median of 230 across 115 observational studies indexed under Aortic Dissection.

A weakened immune system. It can come from an illness, such as HIV or some blood cancers, or from medicines that turn the immune system down, for example after an organ transplant or for an autoimmune disease; steroids at higher doses count.

Procedure: thoracic endovascular aortic repair
In The TEVAR procedure, we implant a stent graft into the diseased area of the thoracic artery, providing a route for the blood to flow within the stent graft and excluding the diseased aorta.
