Patel","Dheeraj Gandhi","Rodney J. Taylor","Graeme Woodworth"],"abstract":"Background: Digital subtraction angiography (DSA) is considered the gold standard for the evaluation of head and neck vascular abnormalities. It serves as a useful diagnostic and, in many cases, therapeutic tool for treatment of acute head and neck bleeding. Case Description: We report the case of a patient who presented with life threatening, uncontrollable epistaxis several weeks after resection of a large recurrent chondrosarcoma of the nasal cavity and anterior skull base. A DSA study, with an adjunctive C-arm computed tomography (CT) (Dyna CT), was ultimately helpful in revealing and precisely localizing a large anterior ethmoidal artery pseudoaneurysm adjacent to the tumor resection cavity. Conclusion: This additional information helped define the arterial anatomy in postoperative region, allowed precise localization and direct ligation of the pseudoaneurysm to resolve the bleeding with a favorable patient outcome.","thumbnailUrl":"https://sni-digital-videos.s3.amazonaws.com/articles/dbdba46a-6068-4c80-bc82-994f0c8c66ae/featured/hero-1782421005193.png","publishDate":"2014-04-11T00:00:00.000Z","doi":"10.4103/2152-7806.130561","categories":["Original Article"],"fullTextUrl":"https://surgicalneurologyint.com/wp-content/uploads/2015/05/3931/SNI-5-48.pdf"}
