Is this trial a fit for you?

Likely a good fit

Adults aged 18 or older who have acute aortic syndrome (aortic dissection, penetrating aortic ulcer, or intramural hematoma) with symptom onset within 14 days and who undergo medical, open, endovascular, or hybrid repair and consent to follow-up.

Probably not a fit

Patients with traumatic or iatrogenic acute aortic syndrome, symptom onset more than 14 days before surgery, or those who decline participation are unlikely to benefit from this registry's findings.

What this trial studies

A multicenter observational registry across Chinese cardiovascular centers is enrolling consecutive adults who underwent surgery for acute aortic syndrome from January 1, 2016 through December 31, 2040. The project collects clinical data, procedural details, inflammatory markers, and information on medical, open, endovascular, or hybrid treatments. Primary early outcomes include severe SIRS, multiple organ dysfunction syndrome (MODS), and SOFA scores at 7 days, with additional long-term adverse event tracking. By comparing inflammatory responses and anti-inflammatory strategies across patients, the registry aims to clarify how inflammation influences short- and long-term outcomes after AAS surgery.

Why it matters

Potential benefit: If successful, this work could identify anti-inflammatory strategies that reduce postoperative inflammation, lower complications, and improve survival after surgery for acute aortic syndrome.

How similar studies have gone: Prior research supports a key role for inflammation in AAS and small studies hint that anti-inflammatory approaches may help, but a large multicenter registry focused on these questions is relatively novel.
