ABSTRACT
Flow diversion (FD) has revolutionized the treatment of cerebral aneurysms. Since the introduction of the Pipeline Embolization Device, there has been a significant shift in the management of cerebral aneurysms, with increasing emphasis being placed on use of endoluminal reconstruction as a means of long-term, durable treatment of aneurysms. Increasingly, FD stents are being used as primary treatment for aneurysms, including those that present with subarachnoid hemorrhage.1 Improper use of FD stents, however, may create havoc, as access to the aneurysm sac is blocked with the placement of these devices. Aneurysms that are incompletely treated with FD may continue to grow and rupture. The inability to use coils or endosaccular devices for treatment of these aneurysms means the only options for treatment are placement of additional FD devices, deconstructive strategies with or without bypass, or microsurgical clipping,2 thereby making an aneurysm that may have been straightforward to treat with another strategy a complex lesion to treat with the presence of the FD stent. Although deconstructive techniques can be used for treatment of failed aneurysm occlusion with flow diversion, where possible, surgical clipping can result in the simplest, most durable solution. Herein we present (Video 1) a case of a patient with a posterior inferior cerebellar artery aneurysm treated previously with FD using a single pipeline embolization device without aneurysm occlusion over 1 year of follow-up who was treated with retrosigmoid craniotomy and clipping of aneurysm. Nuances of the approach selection, clipping of the aneurysm, and preservation of the stent are discussed.
