Application of 64-slice CT angiography in the diagnosis and postoperative evaluation of intracranial aneurysm

Objective To assess the values of 64-slice CT angiography(CTA) in the diagnosis and postoperative followup of intracranial aneurysms after clip.Methods The clinical data of 25 patients suggested intracranial aneurysm by clinical features and their 64-slice CTA perfermonce were retrospectively analyzed.Twenty-one patients who had been treated with clip were underwent both preoperative and postoperative CTA to evaluate aneurysm clipping.Results 64-slice CTA found 25 aneurysms of 21 in 25 patients and could clearly reveal the location,size,shape and the relation with surrounding structure of aneurysms,and it was uniformity with operation result(coincidence rate 100%).The CTA of 21 postoperative patients could clearly reveal the occlusion of the aneurysm,the relationship between the parent vessel and aneurysm clips,the quantity and location of aneurysm clips.Conclusions 64-Slice CTA have important values in the diagnosis and postoperative followup of intracranial aneurysm.
