RT Journal Article SR Electronic T1 Active Hemorrhage into a Postresection Cavity Detected by Neuro-CT Angiography JF American Journal of Neuroradiology JO Am. J. Neuroradiol. FD American Society of Neuroradiology SP 1163 OP 1165 VO 26 IS 5 A1 Walker, Matthew T. A1 Wattamwar, Anoop A1 Mellman, David A1 Mo, Jae YR 2005 UL http://www.ajnr.org/content/26/5/1163.abstract AB Summary: We describe a case demonstrating active extravasation of contrast material into a hematoma resection cavity during CT angiography (CTA) that necessitated emergent reexploration, decompression, and hemostatic control. Our case highlights the value of neuro-CTA in the immediate postoperative setting and describes another scenario where CTA has added value. Prompt recognition of contrast extravasation is critical to the diagnosis and ultimately affects the quality of patient care.
