Abstract

Background: There are many techniques in repairing complete atrioventricular septal defect including: double patch technique, classic single patch technique and modified single patch technique. It's 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.
