Abstract
Background and PurposeTo determine the clinical effects (stent size, and number of stents used) of the Sim&SizeTM simulation software on the endovascular treatment of unruptured saccular intracranial aneurysms with Pipeline Embolization Devices (PED). Materials and MethodsThis study is a retrospective analytical multicenter study of patients treated with PED (Flex and Flex with SHIELD) for intracranial aneurysm in XXXX and XXXX. ResultsThe study included 253 patients, of which 75 were treated in Colombia and 178 were treated in France. The majority of patients were women (83.8%), with a median age of 57.48 years, and had large vessel location (88.1%), with most aneurysms located in the ICA paraclinoid segment (56.8%). Patients in the group with Sim&SizeTM simulation had shorter stents than those without simulation (15.62 mm vs. 17.36 mm, p-value= 0.001). Also, a lower proportion of these patients required more than one stent (1.4% vs. 7.3%, p-value=0.022). There were 7 complications reported in the group that used the Sim&SizeTM simulation software, compared to 9 complications in the group that did not use the software. ConclusionsUsing Sim&SizeTM simulation software for endovascular treatment of patients with intracranial aneurysms using PED reduces the stent length and decreasing the number of devices needed per treatment.
