About this study
Official title: Neurological Complications and Intensive-Care Workload After Emergency Repair of Acute Type A Aortic Dissection: A Retrospective Cohort Study
Single-center retrospective cohort at China Medical University Hospital (Taichung, Taiwan) using fully de-identified electronic health records. Consecutive adults who underwent emergency repair of acute type A aortic dissection between 2021-01-01 and 2025-04-30 were pooled into one cohort. The study measures the incidence and patterns of early postoperative neurological complications and evaluates their association with intensive care unit (ICU) resource use, focusing on prolonged ICU length of stay (LOS ≥ 10 days), ICU and hospital LOS, and duration of mechanical ventilation (MV). No new data collection or patient contact occurs. Institutional Review Board (IRB) approval: CMUH114-REC1-139.
Read the detailed description
Adults (≥ 18 years) undergoing emergency repair for acute type A aortic dissection (ATAAD) at China Medical University Hospital (CMUH) during 2021-01-01 to 2025-04-30 were screened. Exclusions: missing key variables, preoperative stroke within 30 days or modified Rankin Scale (mRS) ≥ 4, pregnancy. The analytic cohort included 274 of 309 screened patients. Neurological complications comprise radiology-confirmed stroke, other focal neurological deficits, paraplegia, or sustained coma/encephalopathy recorded by neurology consultation. Prolonged ICU stay is prespecified as ICU LOS ≥ 10 days in the index admission. Outcomes: primary outcomes are prolonged ICU stay and any postoperative neurological complication; secondary outcomes are ICU LOS (days), duration of mechanical ventilation (hours), hospital LOS (days), in-hospital mortality, and in-hospital death within 30 days of the index surgery. Analyses are performed in R version 4.5.1. Continuous variables are summarized as medians with interquartile ranges (IQRs) and compared using the Mann-Whitney U test; categorical variables are presented as counts and percentages and compared using chi-square or Fisher exact tests. Multivariable logistic regression identifies factors associated with prolonged ICU stay (ICU LOS ≥ 10 days) among hospital survivors using a priori covariates (age, sex, chronic kidney disease stage 4-5, operation time, cardiopulmonary bypass [CPB] time, intraoperative red blood cell [RBC] units transfused, postoperative acute kidney injury [AKI], any postoperative neurological complication). A prespecified sensitivity analysis in the full cohort treats the endpoint as ICU LOS ≥ 10 days or in-hospital death using the same prespecified covariates. Data were de-identified before analysis and stored on secure hospital servers; the study is minimal risk and does not involve United States Food and Drug Administration (US FDA) regulated products.

| Adults undergoing emergency ATAAD repair | Single-center retrospective cohort of consecutive adults (≥18 years) who underwent emergency repair of acute type A aortic dissection at China Medical University Hospital between 2021-01-01 and 2025-04-30; all participants are pooled into one cohort with no protocol-assigned interventions; outcomes are obtained from de-identified records to assess neurological complications and ICU resource use. |
What is being measured
The primary outcome is the main question the study is designed to answer.
Prolonged ICU length of stay (LOS ≥10 days)
Proportion of participants with ICU LOS ≥10 days during the index ICU admission. Unit of measure: percent.
Measured: Through ICU discharge during the index admission (up to 30 days).
Any postoperative neurological complication
Proportion with stroke (CT/MRI confirmed), other focal neurological deficits, paraplegia, or sustained coma/encephalopathy recorded by neurology consultation. Unit of measure: percent.
Measured: Through hospital discharge during the index admission (up to 30 days).
Secondary outcomes (5)
ICU length of stay (days)
ICU LOS summarized as median and IQR; larger values indicate greater resource use. Unit of measure: days.
Measured: Through ICU discharge during the index admission (up to 30 days).
Duration of mechanical ventilation (hours)
Cumulative hours of invasive ventilation from ICU arrival to final extubation. Unit of measure: hours.
Measured: Through final extubation during the index hospitalization (up to 40 days).
Hospital length of stay (days)
Days from hospital admission to discharge; deaths counted up to date of death. Unit of measure: days.
Measured: Through hospital discharge during the index admission (up to 65 days).
In-hospital mortality
All-cause death before discharge from the index hospitalization. Unit of measure: percent.
Measured: Through hospital discharge during the index admission (up to 30 days).
In-hospital mortality within 30 days
All-cause death occurring during the index hospitalization within 30 days after the index surgery (deaths after hospital discharge were not captured).
Measured: Up to 30 days after index surgery, during the index hospitalization.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.

Questions about this trial
What is this clinical trial studying?
An observational study of Aortic Dissection and Stroke, run by China Medical University Hospital at 1 site in Taiwan.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 1 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 26 Dec 2025. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Taiwan. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Prolonged ICU length of stay (LOS ≥10 days) (time frame: Through ICU discharge during the index admission (up to 30 days).). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT07167628, which also lists 10 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
