Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is a retrospective study based on the data available in our hospital database for ATAAD patients from January 2020 to December 2021. These patients were divided into two groups according to the surgical procedures of aortic root. This study compared baseline data, perioperative and short-term follow-up results between the two groups to evaluate the efficacy and safety of XJ-procedure in ATAAD.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Acute type A aortic dissection (ATAAD) is a life-threatening disease with high mortality. Surgery remains the gold standard for the treatment of ATAAD. In recent years, ATAAD is still a persistent challenge for cardiovascular surgeons. This is a retrospective study based on the data available in our hospital database for ATAAD patients undergoing total aortic arch replacement with elephant trunk stent under cryogenic stop circulation from January 2020 to December 2021. These patients were divided into two groups according to the surgical procedures of aortic root: continuous aortic root suture group (CARS group); "aortic root reinforcement combined with vascular grafts eversion and built-in", which was created by our group and to be named as XJ-procedure (XJ-procedure group, XJ is an acronym for Xi'an Jiaotong University). The main outcome was defined as 30-day mortality. Secondary outcomes included the postoperative bleeding necessitating re-operation and the incidence of anastomotic pseudoaneurysm, residual aortic root dissection and severe aortic regurgitation before discharge and at 3 and 6 months after the operation. This study compared baseline data, perioperative and short-term follow-up results between the two groups to evaluate the efficacy and safety of XJ-procedure in ATAAD.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

CARS group

In the CARS group, 3-0 polypropylene was used to suture the proximal end of aortic with the vascular grafts continuously, followed by one interrupted suture loop of 3-0 polypropylene for reinforcement.

No Intervention.

Intervention Type OTHER

No Intervention.

XJ-procedure group

In the XJ-procedure group, a 1.5-2cm wide bovine pericardial patch and graft ring were placed inside and outside the aortic root and against the aortic wall, respectively, and continuously sutured near the commissure using 5-0 polypropylene. Then an eversion about 15mm of vascular graft was intermittently sutured to full layers of aortic vascular with 2-0 pad polyester sutures. Finally, the eversion and aortic wall were continuously sutured together in one more turn.
