Diagnostic yield of repeat catheter angiography in patients with catheter and computed tomography angiography negative subarachnoid hemorrhage.

摘要: BACKGROUND The yield of repeat catheter angiography in patients with subarachnoid hemorrhage (SAH) who have negative initial and computed tomography (CT) angiograms is not well understood. OBJECTIVE To determine the a prospective cohort SAH CT angiograms. METHODS From January 1, 2005, until September 2010, we instituted protocol which documented by noncontrast (NCCT) or cerebrospinal fluid (CSF) xanthochromia were evaluated 7 days 3 months after presentation to assess for causative vascular abnormalities. RESULTS Seventy-two included, mean age 53.1 years (median, 53.5 years; range, 19-88 years). Forty-six female (63.9%) 26 male (36.1%). Thirty-nine had nonperimesencephalic (54.2%), 29 perimesencephalic (40.3%), 4 CSF (5.5%). first angiogram performed demonstrated abnormality (yield 4.2%), 2 5.1%), 1 3.4%). second 43 (59.7%) did demonstrate any No abnormalities found xanthochromia. CONCLUSION Repeat valuable evaluation angiograms, demonstrating 4.2% patients.
