Arterial cannulation sites for the surgical repair of type A aortic dissection (AAD) have evolved from right axillary artery (AA) cannulation to bilateral carotid artery (CA) based of femoral artery (FA) cannulation. Postoperative descending aorta remodeling is closely linked to the false lumen area ratio (FLAR), defined as false lumen area/aortic area, as well as to the incidence of renal replacement therapy (RRT).
To investigate the effect of the updated arterial cannulation strategy on des
A total of 443 AAD patients who received FA combined cannulation between March 2015 and March 2023 were included in the study. Of these, 209 received right AA cannulation and 234 received bilateral CA cannulation. The primary outcome was the change in FLAR, as calculated from computed tomography angiography in three segments of the descending aorta: Thoracic (S1), upper abdominal (S2), and lower abdominal (S3). Secondary outcomes were the incidence of RRT and the serum inflammation response, as observed by the levels of high sensitivity C reaction protein (hs-CRP) and Interleukin-6 (IL-6).
The postoperative/preoperative ratio of FLAR in S2 and S3 was higher in the AA group compared to the CA group (S2: 0.80 ± 0.08 vs 0.75 ± 0.07, P < 0.001; S3: 0.57 ± 0.12 vs 0.50 ± 0.12, P < 0.001, respectively). The AA group also had a significantly higher incidence of RRT (19.1% vs 8.5%, P = 0.001; odds ratio: 2.533, 95%CI: 1.427-4.493) and higher levels of inflammation cytokines 24 h after the procedure [hr-CRP: 117 ± 17 vs 104 ± 15 mg/L; IL-6: 129 (103, 166) vs 83 (69, 101) pg/mL; both P < 0.001] compared to the CA group.
The CA cannulation strategy was associated with better abdominal aorta remodeling after AAD repair compared to AA cannulation, as observed by a greater change in FLAR and lower incidence of RRT.
Core Tip: Arterial cannulation sites for the surgical repair of type A acute aortic dissection have gradually evolved from right axillary artery cannulation to bilateral carotid artery cannulation based on femoral artery cannulation. This retrospective observational study found the carotid artery cannulation strategy was associated with better postoperative abdominal aorta remodeling with a higher false lumen area ratio, a lower incidence of renal replacement therapy, and lower levels of inflammation cytokines compared with the axillary artery cannulation mode.
