: There are many techniques in repairing complete atrioventricular
septal defect including: double patch technique, classic single patch technique and
modified single patch technique. It is still debated which of these techniques is
superior to the other one, our objective was to contrast the outcomes following
surgery between the modified single patch and double patch techniques for repair
of complete atrioventricular septal defect.
Methods: This study includes 100 infants who underwent complete atrioventricular
septal defect repair. Individuals were split into patients repaired with modified single
patch as group A (n= 50), and patients repaired with double patch as group B (n=
50).
Results: Group B showed significantly higher Cardiopulmonary bypass time (110 ±12
vs. 88 ±8 min, P < 0.001) Aortic cross clamp time (81 ±7 vs. 61 ±5 min, P < 0.001), ICU
stay (10 ±1 vs. 9 ±1 day, P < 0.001), hospital stay (17 ±2 vs. 15 ±1 day, P < 0.001), and
drainage amount (310 ±98 vs. 194 ±80, P < 0.001). No changes observed among
groups of the study in other operative or postoperative statistics.
Conclusion: Modified single-patch repair and two-patch repair did not yield
significantly different results in the total correction of atrioventricular septal defects.
