Aortic arch laceration during aortic coarctation repair in a low-weight neonate and use of an extra-anatomical conduit.

: We report the case of a 3-day-old male baby, weighing 1.6 kg with severe aortic coarctation and associated cardiac anomalies and extracardiac defects. We adopted an extra-anatomical conduit running from the left carotid artery to the descending aorta after laceration of the distal aortic arch due to extreme tissue fragility and baby immaturity.
