Modified Isolation Selective Cerebral Perfusion Technique for Intracardiac Disease with Mobile Atheroma.

Isolation selective cerebral perfusion (ISCP) technique is reportedly an effective method for preventing brain complications during the treatment of arch aneurysms. Here we present the case of a patient with intracardiac disease complicated by mobile atheroma in the proximal aorta. In this patient, not only the arterial cannulation of the ascending aorta might have posed a high risk of brain stroke but also the original ISCP technique could not be applied. We applied the ISCP technique for non-aortic disease without using circulatory arrest to prevent aortogenic brain embolism. The patients who underwent treatment using this technique were discharged without neurologic complications.
