Ictus e prevenzione dell’ictus in cardiochirurgia e in chirurgia dell’aorta toracica Stroke and stroke prevention in cardiac and thoracic aortic surgery

Perioperative stroke and neurological injuries in general are complications that can occur during and after cardiac surgery, particularly in aortic surgery that involves the aortic arch. The overall incidence of early and delayed stroke is about 1% according to recent meta-analyses. This incidence depends on interindividual risk factor profile and type of surgery. In order to reduce cerebrovascular complications during cardiac surgery, a number of preventative measures can be taken, including the evaluation of atherosclerotic plaques, the site of cannulation and neuroprotection strategies. During aortic arch surgery, main strategies for cerebral protection are represented by deep hypothermic circulatory arrest, retrograde and antegrade cerebral perfusion.
