Application of 64 slice CT angiography in the peoperative diagnosis and postoperative evaluation of intracranial aneurysms

Objective:To assess the value of 64 slice CT angiography(CTA) in the preoperative diagnosis and postoperative follow up of intracranial aneurysms after clip.Methods:25 patients who were admitted under clinical symptoms and signs suggestive of harboring intracranial aneurysms were underwent CTA examinations,and 21 patients were discovered intracranial aneurysms who were confirmed by operation,they also were underwent CTA examinations postoperative.We evaluated aneurysm clipping by preoperative and postoperative CTA.Results:64 slice CTA found 25 aneurysms of 21 in 25 patients,and CTA could clearly reveal the location,size,shape and the relation with surrounding structure of aneurysms,it was uniformity with operation results(coincidence 100%).The CTA of 21 postoperative patients could clearly reveal the occlusion of the aneurysm,the relationship between the parent vessel and aneurysm clips and the quantity and location of aneurysm clips.Conclusion:64 slice CTA have important values in the preoperative diagnosis and postoperative followup of intracranial aneurysms after clip.
