Abstract:
Objective To explore the clinical efficacy of single-branch intraoperative stent combined with modified bilateral cerebral perfusion in type A aortic dissection. Methods A retrospective analysis was conducted on the clinical data of patients who underwent surgery for type A aortic dissection at the First Affiliated Hospital of Anhui Medical University from January 2021 to May 2024. Patients were divided into a test group (single branch stent+modified bilateral cerebral perfusion) and a control group (traditional surgical method, straight stent+unilateral cerebral perfusion) according to the surgical method. Propensity score matching analysis was used to match the two groups of patients with a ratio of 1:1, and the perioperative data and clinical efficacy after matching were compared. Results A total of 14 patients were included in the test group, including 13 males and 1 female, with an average age of (46.6±16.4) years. There were 56 patients in the control group, including 38 males and 18 females, with an average age of (52.1±11.7) years. After propensity score matching, 14 patients were included in each group. Compared with the control group, the ventilator support time [(27.4±24.3) h vs. (93.4±88.0) h, P=0.018], length of stay in the intensive care unit [(2.8±1.8) d vs. (8.7±6.5) d, P=0.009], and postoperative awakening time [(5.4±2.2) h vs. (8.8±4.8) h, P=0.047] in the test group were shorter than those in the control group, with statistically significant differences. There was no statistical difference in neurological complications between the two groups (P=1.000). Conclusion Single-branch intraoperative stent combined with modified bilateral cerebral perfusion can effectively shorten ventilator support time, length of stay in the intensive care unit, and postoperative awakening time, and is safe and effective for the treatment of type A aortic dissection, which is worth further promotion.
