RT Journal Article SR Electronic T1 Epidural Blood Patch at C2: Diagnosis and Treatment of Spontaneous Intracranial Hypotension JF American Journal of Neuroradiology JO Am. J. Neuroradiol. FD American Society of Neuroradiology SP 2663 OP 2666 VO 26 IS 10 A1 Ansaar Rai A1 Charles Rosen A1 Jeffrey Carpenter A1 Vincent Miele YR 2005 UL http://www.ajnr.org/content/26/10/2663.abstract AB Summary: Spontaneous intracranial hypotension in a 37-year-old man with intractable headaches was diagnosed on MR imaging. A generous CSF leak was identified at C2 on CT myelography. Successful treatment was performed with CT-guided blood patch at the leakage site after the patient had failed 2 lumbar blood patches. Imaging-guided precise placement of the blood patch is safe and recommended when a lumbar blood patch away from the leakage site could be ineffective.
