A Successful Repair of Pseudocoarctation With Associated Aortic Arch Aneurysm in an Eight-Month-Old Infant.

Pseudocoarctation of the aorta is an uncommon congenital entity characterized by juxtaductal elongation and tortuosity of the aortic arch. It is known to be associated with aneurysm formation. Our patient is a 7.7-month-female infant followed prenatally by magnetic resonance imaging that detected this anomaly. Subsequently, postnatal preoperative computed tomography angiography was confirmatory. The operation comprised resection of the aneurysmal portion of the aorta and extended end-to-end reconstruction, without prosthesis usage. The left subclavian artery was reimplanted into the left carotid artery. The postoperative course was uneventful. Computed tomography aortography and transthoracic echocardiography demonstrated no residual stenosis at six months of follow-up.
