ObjectiveTo compare short-term outcomes of radical correction of tetralogy of Fallot (TOF)with or without transcatheter embolization of major aortopulmonary collaterals (APC). MethodsClinical data of 58 TOF patients undergoing radical correction from January 2008 to June 2013 in the Department of Cardiovascular Surgery, First Affiliated Hospital of Zhengzhou University were retrospectively analyzed. There were 36 male and 22 female patients. Among them, 22 patients (Group A, 12 males and 10 females)received radical TOF correction combined with transcatheter embolization of major APC, and 36 patients (Group B, 24 males and 12 females)received radical TOF correction alone. Average age of group A was (24.91±6.77)years and that of group B was (22.42±5.06)years. Aortic cross-clamping time, ICU stay, postoperative hospital stay, left ventricular ejection fraction (LVEF)7 days and 3 months after the operation were compared between the 2 groups. ResultsThere was no in-hospital death. There was no statistical difference in sex, age, preoperative McGoon ratio or hemoglobin (Hb)levels between the 2 groups (P > 0.05). Aortic cross-clamping time[ (43.87±13.02)minutes vs. (53.60±11.69)minutes, P < 0.05], ICU stay[ (26.09±4.84)hours vs. (28.87±4.38)hours, P < 0.05] and postoperative hospital stay[ (12.32±1.81)days vs. (13.67±2.14)days, P < 0.05] of group A were significantly shorter than those of group B. LVEF 7 days after the operation of group A was significantly higher than that of group B (56.64%±8.19% vs. 52.58%±5.62%, P < 0.05), and there was no statistical difference in LVEF 3 months after the operation between the 2 groups (58.50%±8.78% vs. 55.42%±6.18%, P > 0.05). ConclusionFor surgical treatment of TOF, compared with radical correction alone, radical correction combined with transcatheter embolization of major APC can significantly shorten aortic cross-clamping time and improve postoperative heart function recovery.
