OBJECTIVE: Aortic arch replacement in acute type A aortic dissection patients remains the most challenging cardiovascular operation. Herein, we described our modified Y-graft technique using the Femoral Artery Bypass (FAB) and the One Minute Systemic Circulatory Arrest (OSCA) technique, and assessed the short-term outcomes of the patients.
METHODS: Between February 2015 and November 2017, 51 patients with acute type A aortic dissection underwent aortic arch replacement. Among them, 23 patients underwent FAB while 28 patients underwent both FAB and OSCA. The intraoperative data and postoperative follow-up data were recorded. The follow-up data of patients with traditional Y-graft technique were collected from previously reported studies.
RESULTS: In the FAB group, two patients died due to pulmonary infection (30-day survival rate, 91.3%), and two patients were paralyzed from the waist down. Hemodialysis was performed for five patients (21.7%) before hospital discharge. Fifteen patients (65.2%) received respiratory support for more than 2-days and eight patients (34.8%) for more than 5-days. These follow-up results were comparable or better than the patients with traditional Y-graft technique. Furthermore, compared to the FAB group, the morbidity due to neurological dysfunction and acute renal failure was significantly reduced in the FAB+OSCA group. Moreover, the respiratory support, length of postoperative stay and ICU stay were shortened.
CONCLUSIONS: This study clarified the feasibility of FAB and OSCA technique in modifying Y-graft technique. The acute type A aortic dissection patients showed less surgical complications and favorable short-term outcomes after this surgery.
