E-049 Intraprocedural Diagnosis of Flow-Diverting Stent Malapposition during Endovascular Aneurysm Treatment with DynaCT Imaging (original) (raw)

Journal of neurointerventional surgery, 2014

Abstract

The treatment of large, complex intracranial aneurysms is being increasingly performed using flow-diverting stents (FDS) such as the Pipeline Embolization Device (PED). Malapposition of a FDS to the parent artery wall decreases the likelihood of aneurysm obliteration and increases the risk of both immediate and delayed complications. DynaCT is a novel imaging modality which uses a flat plane detector to generate computed tomography images using the same C-arm employed for digital subtraction angiography. We present a case of a 40 year-old female with a large, unruptured, cavernous internal carotid artery (ICA) aneurysm who was treated with endovascular obliteration using a PED. A 6 French Chaperon guide catheter was navigated into the left ICA through which subsequent control angiograms could be performed. Cerebral angiography showed a lobular, cavernous ICA aneurysm measuring 11 mm in maximal diameter with a wide 7.5 mm neck. An Excelsior XT-27 microcatheter advanced over an Asahi ...
