Abstract

We analyzed the incidence of ischemic complications after internal trapping for ruptured VA dissecting aneurysms. Between April 2001 and August 2005, nine cases of ruptured VA dissecting aneurysms, five in women, "proximal" or distal (distal type) to the origin of the PICA, were treated by internal trapping in the acute stage after SAH. There were four cases of proximal type and five of distal type. The demographics of the patients were reviewed in the medical charts and radiological findings were evaluated by neuroradiologists. The dissected site was completely obliterated and PICA was preserved in all cases. Follow-up angiography performed five to 19 days after treatment revealed complete obliteration of the aneurysm and patency of the PICA. The incidence of perioprocedural ischemic complications for the PICA-distal type (75%) was higher than that for the PICA-proximal type (20%). Here we retrospectively analyzed and discussed the incidence and mechanisms of ischemic complications.
