Single branched endografts for the preservation of left subclavian artery in the treatment of zone II thoracic aortic lesions a systematic review and meta-analysis.

While we have displayed the safety and feasibility of single branched endografts in the treatment of zone II thoracic aortic lesions, physicians should be aware of the persistency displayed by early type I endoleaks eventually requiring re-intervention. The variations in device and lesion characteristics accompanied by the short-term follow-up presented in our review do not allow for definite conclusions to be drawn, necessitating further research through high-quality randomized controlled trials.
