Background:
We aimed to investigate the in-hospital and midterm outcomes of patients undergoing ascending aortic replacement (AAR) through a partial or a full sternotomy approach through a propensity matching analysis.
Methods:
We retrospectively included all patients (n = 167) who underwent elective AAR in our institution between 2013 and 2020. The study population was divided into two groups according to the surgical access (40 patient in the partial sternotomy or "PS" group and 127 in the full sternotomy or "FS" group). Due to the significant differences between the groups, a propensity matching of 1:3 was applied. In-hospital complications, survival, and reoperation at follow-up were investigated.
Results:
The PS group showed higher cross-clamp and cardiopulmonary bypass times than the FS group (94.2 vs. 83 minutes and 164.2 vs. 126.8 minutes, respectively). Moreover, the postoperative ventilation time was significantly higher in the PS group, but it did not affect the length of stay in the intensive care unit (ICU). The incidences of bleeding, stroke, and mortality were comparable between the two groups (11 vs. 3%, 3 vs. 6%, and 5 vs. 3%, respectively). After a median follow-up of 2 ± 1.98 years, the Kaplan-Meier analysis showed no significant differences between the two groups (log-rank, p = 0.17) in terms of survival.
Conclusion:
The surgical ascending aorta replacement through a partial sternotomy is associated with longer operative times, but this does not affect the early as well as the long-term follow-up.
