HYPOTHERMIA AND CARDIOPULMONARY BYPASS DURING RESECTION OF EXTENSIVE ARTERIOVENOUS MALFORMATION FOLLOWED BY MICROVASCULAR RECONSTRUCTION

A patient is presented in whom hypothermic hypoperfusion and cardiopul monary bypass were used to aid in resection of a mandibular arterioven ous malformation, This was followed by immediate microvascular reconst ruction using a fibular osteocutaneous microvascular free tissue trans fer. Prior attempted resection after highly selective embolization had proved inadequate, We found that the operative field, using hypotherm ic hypoperfusion was bloodless and enabled safe, rapid excision of the malformation, After patient rewarming, microvascular reconstruction w as readily performed, No neurologic sequelae resulted, and no recurren ce of the malformation has been noted.
