Short-term follow up of pipeline embolization device (PED) deployment for treatment of intracranial carotid aneurysm / 中华放射学杂志

ABSTRACT

Objective To explore the technical skills and short-term efficacy of Pipeline Embolization Device (PED) deployment for endovascular treatment of complex intracranial carotid aneurysm. Methods The medical charts of 6 cases who underwent PED implant procedure in our institute from Jan. to Jun. 2015 were reviewed, including 4 female and 2 male; the mean age was (56 ± 13) years, ranging from 34—70 years. All the 6 cases suffered from intracranial carotid aneurysm and PED implant procedures were performed to cover the aneurismal neck under general anesthesia, while dual antiplatelet treatment (Bayaspirin+Plavix) was administered. The basic characteristics and peri-procedural adverse events were recorded, interview and mRS score were done by telephone 1 month after procedure, clinical examination and DSA angiographic re-check were made 3 months following procedure, respectively. Status of aneurysm occlusion was evaluated by Raymond grading scale. Results All 6 aneurysms involved were unruptured. Technical success was achieved in all procedures for 6 cases, of which 3 cases were single PED implantation and the other 3 PED adjuncted to coiling. No procedure related complication was detected during 30 days after operation. Follow up with 1.5—4.8 months (median 2.8 months) were conducted and last follow up revealed good outcome (mRS<2) in all cases. The control angiography showed contrast filling aneurismal sac even after PED implantation, DSA recheck performed in 2 cases at 3 months after operation and revealed good obstruction of aneurysm (Raymond grade≤2). Conclusion Domestic preliminary study shows PED implantation seems to be a safe and effective modality for treatment of complex intracranial carotid aneurysms.
