Objective: After analysis of the feature of digital subtraction angiography (DSA) in the intracranial aneurysms and the CT showing in subarachoid space hemorrhage (SAH)

emphasis is laid on the investigation of the correlation between the location

shape of intracranial aneurysms and CT showing SAH measurement with the clinical presentation. Methods: We retrospectively analyzed the relationship between the position

shape and SAH measurement CT presentation of 163 patients cerebral aneurysms and 63 patients SAH CT presentation with their clinical manifestations. Results: The location

shape

size

growth and SAH measurement of cerebral aneurysms were related directly to their clinical symptoms;CT presentation with SAH measurement was obviously correlated

but the location and shape of cerebral aneurysms were not.DSA or rotation DSA for cerebral aneurysms are shown more clearly?and directly

especially when combined with CT.The diagnosis and therapy of cerebral aneurysms can supply reliable basis. Conclusion: The relationship between the location

shape

size and SAH measurement of intracranial aneurysms with the clinical presentations is not specific;the CT presentation with SAH measurement is corelated

but the origin of cerebral aneurysms is not.
