Abstract:
Objective To evaluate the safety and effectiveness of Pipeline embolization device (PED) for the treatment of large and giant intracranial aneurysms.Methods Frorn November 2014 to May 2016,the clinical and radiological data of 33 patients with intracranial aneurysm confirmed by DSA or head CT angiography (CTA) or head magnetic resonance angiography (MRA) at the Department of Neurosurgery,Changhai Hospital,the Second Military Medical University were enrolled retrospectively.Its safety and effectiveness were evaluated.Results The Pipelines were successfully released in 33 patients with 35 aneurysms,10 aneurysms were implanted by using PED alone,25 were implanted by using PED combined with coil embolization (including 2 were implanted by using Pipeline bridging technology).During the perioperative period,1 thrombotic event(one aneurysm) occurred and had hemorrhagic transformation.One(one aneurysm) died of fatal aneurysm delayed bleeding.Thirty-one patients (33 aneurysms) were followed up clinically,the follow-up time was 4-18 months,no bleeding or thrombosis events occurred.Eighteen aneurysms received a short-term postoperative imaging follow-up (3-5 months,enhanced MRA or DSA),of which 10 had neck residue or aneurysm development,and 8 aneurysms did not have development at all,and 19 achieved postoperative mid-term imaging follow-up (6-16 months,enhanced MRA or DSA).Two of them had neck residue and 17 did not develop at all.Conclusion Pipeline for the treatment of intracranial large and giant aneurysms may be safe and effective.However,the complications of intracranial hemorrhage cannot be ignored after implantation of embolization device.Its related mechanism needs to be further studied.
