The Importance of Catheter Angiography in Computed Tomography Angiography-Negative Subarachnoid Hemorrhage
Computed tomography angiography (CTA) has become an effective tool in the evaluation of patients with subarachnoid hemorrhage (SAH), but it still has limitations. Up to 15% of non-traumatic SAH cases are negative on CTA. The benefits of catheter angiography in the evaluation of certain cases of CTA-negative SAH have been previously demonstrated. Here, we present the case of a 48-year-old female...
متن کاملYield of catheter angiography after computed tomography negative, lumbar puncture positive subarachnoid hemorrhage [corrected].
BACKGROUND AND PURPOSE Patients suspected of having aneurysmal subarachnoid hemorrhage (SAH) are initially evaluated with noncontrast head computed tomography. If the computed tomography is negative, but clinical concern for SAH is high, a lumbar puncture with cerebrospinal fluid analysis is typically performed. The purpose of this study was to evaluate the accuracy of cerebrospinal fluid xanth...
متن کاملComputed tomographic angiography for the evaluation of aneurysmal subarachnoid hemorrhage.
OBJECTIVES Computed tomography (CT) followed by lumbar puncture (LP) is currently the criterion standard for diagnosing subarachnoid hemorrhage (SAH) in the emergency department (ED); however, this is based on studies involving a limited number of patients. The authors sought to assess the ability of CT angiography (CTA), a new diagnostic modality, in conjunction with CT/LP to detect SAH. MET...
متن کاملCerebral computed tomographic angiography scan delay in subarachnoid hemorrhage.
CONTEXT Computed tomographic angiography (CTA) is widely applied in the evaluation of cerebral vessels. Contrast enhancement in cerebral CTA without care or test bolus is not always sufficient for high-quality images. AIMS Evaluation of the possibilities of calculation of scan delay for cerebral CTA in case of subarachnoid hemorrhage (SAH), based on clinical data of a patient and to find out ...
متن کاملThe comparative study on diagnostic validity of cerebral aneurysm by computed tomography angiography versus digital subtraction angiography after subarachnoid hemorrhage*
BACKGROUND In order to declare the preoperative diagnostic value of brain aneurysms, two radiological modalities, computed tomographic angiography and digital subtraction angiography were compared. METHODS In this descriptive analytic study, diagnostic value of computed tomographic angiography (CTA) was compared with digital subtraction angiography (DSA). Sensitivity, specificity, positive an...
