Aneurysms involving the aortic arch are formidable surgical challenges. Though the first successful surgery was performed more than 40 years ago, the risk of surgical treatment remained prohibitively high until recently. Intra-operative protection of the brain from ischaemic injury was the main concern. Deep hypothermic circulatory arrest with retrograde cerebral perfusion technique has considerably reduced the risk of surgery to acceptable levels.
累及主动脉弓的动脉瘤是严峻的外科挑战。尽管首例成功手术是在40多年前实施的，但直到最近，外科治疗的风险仍然高得令人望而却步。术中保护大脑免受缺血性损伤是主要关注点。采用逆行脑灌注技术的深低温停循环已将手术风险大幅降低至可接受水平。
