Key result
Surgical division and reimplantation of the isolated subclavian artery onto the aortic arch or common carotid artery resulted in good immediate and midterm outcomes in four patients.
Case Report (n=4)
Surgical division and reimplantation is an effective treatment for the rare anomaly of isolated subclavian artery, yielding good immediate and midterm outcomes.
May support reimplantation in this rare anomaly; case reports leave open need for prospective confirmation.
Isolation of the subclavian artery is a rare aortic arch anomaly with fewer than 100 cases reported in the literature. Left subclavian artery isolation is seen in 0.8% of right aortic arches, and right subclavian artery isolation is seen four times less frequently. Other intracardiac or arch malformations are usually associated, among which tetralogy of Fallot is commonly described. We describe the presentation, preoperative imaging, surgical strategies, and outcomes of four patients with this rare condition and review the published literature. The embryological basis and interesting pathophysiology are also discussed. Surgical division and reimplantation of the isolated subclavian artery onto the aortic arch or common carotid artery is the treatment of choice, with good immediate and midterm outcomes.

Sen et al. (2016) conducted a case report in Isolated subclavian artery (n=4). Surgical division and reimplantation was evaluated on Immediate and midterm outcomes. Surgical division and reimplantation of the isolated subclavian artery onto the aortic arch or common carotid artery resulted in good immediate and midterm outcomes in four patients.
