ABSTRACT

Introduction: Particulate embolism to the brain during open heart surgery is a catastrophic complication. Despite multiple efforts to avoid or reduce these types of events, non significant results have been obtained. This report shows the utilization of an endoaortic filter which captures loose circulating particles during open heart surgery. Material and methods: We performed a prospective study of 20 patients suffering from severe degenerative calcified disease of the aortic valve and annulus. Fifty percent of the patients were operated utilizing an endoaortic particle filter, and the rest underwent conventional surgery. Postoperative cardioembolic complications were analyzed, as well as the usefulness of transoperatory filtration. Results: There were no neurologic transoperative complications in the filtration group. One patient (10%) presented a transient ischemic attack at the 4th postoperative day. Three patients (30%) from the control group presented with neurologic embolic complications. Macroscopic embolized particles were observed in 5 (50%) of the utilized filters. Conclusions: Utilization of the endoaortic filter demonstrated the ability to capture loose particles during open heart surgery and is associated with less neurologic transoperatory complications.
