Event Description

This complaint is from a literature source.The citation is as follows: thaci b, nuño m, varshneya k, gerndt ch, kercher m, dahlin bc, waldau b.Three-dimensional aneurysm volume measurements show no correlation between coil packing density and recurrence.Heliyon.2020 oct 8;6(10):e05170.Doi: 10.1016/j.Heliyon.2020.E05170.Pmid: 33083618; pmcid: pmc7551363.Objective and methods: endovascular treatment is the mainstay therapy for brain aneurysms.About 15% of patients need retreatment within six months due to early recanalization.This study investigates the risk factors associated with treatment failure.: this retrospective cohort study includes endovascularly treated aneurysm cases between july 2012 and december 2015 at the university of california davis medical center with pre-treatment and early post-treatment imaging.Of the 50 patients who met the inclusion criteria, 41 (82.0%) were female, with an average age of 61 years.Most aneurysms were on the anterior communicating artery (40%) or posterior communicating artery (22.0%), and 34 (68%) aneurysms were ruptured.The coils used were cerecyte (cerenovus), axium (medtronic) and stryker neurovascular.Lot, model and catalog number are not available, but the suspected cerenovus device possibly associated with reported adverse events: enterprise vascular reconstruction device (vrd) & cerecyte coils concomitant cerenovus devices that were also used in this study: n/a.Concomitant non-cerenovus devices that were also used in this study: axium coils (medtronic); stryker neurovascular coils; lvis stent (microvention); neuroform ez/ez3 stent (stryker); pipeline embolization device (medtronic).Adverse event(s) and provided interventions: per table 3, there was one patient who received an enterprise stent that experienced early aneurysm recurrence, or treatment failure.Early treatment failure was observed in 14 endovascularly treated patients (10 coiling only, 4 stent-assisted).Although adverse events were noted, the article does not provide sufficient information to determine which manufacturer's medical device is associated with the adverse events.
