Abstract:
Objective To evaluate the short-term effect of Pipeline embolization device (PED)for the treatment of unruptured wide-necked intracranial aneurysms. Methods From October 2015 to September 2016,15 consecutive patients with unruptured wide-necked intracranial aneurysm (aneurysm neck and aneurysm body ratio ≥0. 5)treated with PED at the Department of Neurosurgery,the Second Affiliated Hospital of Nanchang University were enrolled retrospectively. Their clinical and imaging data were analyzed. Kamran scale was used to evaluate the embolization rate of aneurysms and the changes of the parent arteries. DSA examination was performed again at 6 -12 months after operation. Results Fifteen PED were implanted in 15 patients with unruptured wide-necked intracranial aneurysms,including 13ophthalmic artery aneurysms,1 posterior communicating artery aneurysm,and 1 cavernous sinus aneurysm. The technical success rate was 100% . Immediately after PED implantation,Karman rating of 15 cases were aneurysm grade 2 embolization,parent artery grade A (grade 2a). DSA examination was performed again at 6 - 12 months after operation showed that 14 patients were aneurysm grade 4,parent artery was grade A (grade 4a). One patient (ophthalmic artery aneurysm)underwent the second DSA examinations at 6 and 12 months after operation showed that the residual development of aneurysms. The aneurysm embolization was grade 3, and the parent artery was grade A (grade 3a). No branch artery occlusion was observed. Non of them had neurological deficit. The modified Rankin scale score was 0 in all 15 patients. Conclusion The use of PED in the treatment of unruptured wide-necked intracranial aneurysms has a higher occlusion rate. Its long-term effect still needs further follow-up.
