Conversion of lusoric artery into right subclavian artery in one-stage neonatal repair of aortic arch anomalies and intracardiac defects.
In 2 patients, a lusoric artery was compressing the mediastinal structures during a one-stage repair of type B aortic arch interruption and ventricular septal defect. In order to prevent the long-term complications of sacrifice of the subclavian artery, the lusoric artery was not simply divided but converted into a regular right subclavian artery by re-implantation of the abberant vessel at the origin of the right carotid artery during the one-stage repair. At follow up, both patients have normal right radial arterial pulsations. In one patient, angiography was repeated and confirmed a well functioning right subclavian artery. Conversion of a lusoric artery into a right subclavian artery during one-stage repair of aortic arch anomalies and intracardiac defects is not only feasible but also indicated to preserve subclavian artery function and to prevent compression of the mediastinal structures by a vascular ring.
