Management of a giant intracranial aneurysm using surface-heparinized extracorporeal circulation and controlled deep hypothermic low flow perfusion. A case report.

Extracorporeal circulation with controlled hypothermic low flow perfusion was introduced during the surgical treatment of a patient with a giant intracranial aneurysm of the anterior communicating artery. Heparin-coated equipment (Carmeda Bio-Active Surface; CBAS) was utilized, thus reducing the need for systemic heparinization. Direct cannulation of the right atrium and aorta was established through thoracotomy.
