Utilization of the aortic flap above the facing commissure in arterial switch operations
1Department of Surgery, National Taiwan University Hospital, Taipei, Taiwan.
Background:
The aortic flap above the facing commissure after removal of the coronary button from the aortic sinus can be utilized for reconstruction in an arterial switch operation.
Methods:
The free flap was used to reconstruct the coronary artery in two cases, as a medially based trapdoor. A rotational flap was inserted into the cut-open right pulmonary artery to augment the neopulmonary arterial anastomotic site in another case.
Results:
All patients are doing well at mid term follow-up.
Conclusions:
The indications of each method and reported tricks to avoid coronary artery kinking during an arterial switch operation are discussed.
