Clinical Trial Summary

From November 2004 to June 2020, there were more than 200 patients with acute TAAD patients who underwent aortic surgery at our hospital.Of all the patients in the study period, there were 34 patients (defined as study group) who sought for medical attention with symptoms for several days (median 5 days, range 3-7 days) or deferred aortic surgery several days later (median 3 days, range 2-7 days) even though acute TAAD was diagnosed on the same day when chest pain or back pain occurred. For reducing the selection bias, propensity score matching (PSM) was used to match the study group with the control group from all the patients treated at our hospital during the study period. Comparison between the two groups was performed.

Description:

From November 2004 to June 2020, there were more than 200 patients with acute TAAD patients who underwent aortic surgery at our hospital. The research protocol used in this study was approved by the institutional review board of MacKay Memorial Hospital (IRB number: 21MMHIS005e). Of all the patients in the study period, there were 34 patients (defined as study group) who sought for medical attention with symptoms for several days (median 5 days, range 3-7 days) or deferred aortic surgery several days later (median 3 days, range 2-7 days) even though acute TAAD was diagnosed on the same day when chest pain or back pain occurred. The mean age at presentation was 60.2 +/- 13.2 years (range 33.4~83.5 years). All the patients in the study group were divided into 3 groups: DP group (n=22) with acute TAAD diagnosis delayed by patient but received prompt aortic surgery; DD group (n=4) with acute TAAD diagnosis delayed by patient and received deferred aortic surgery; ID group (n=8) with acute TAAD diagnosis on the same day when the symptoms occurred but received deferred aortic surgery several days later. For reducing the selection bias, propensity score matching (PSM) was used to match the study group with the control group from all the patients treated at our hospital during the study period. Comparison between the two groups was performed.
