Event Description
|
The event was reported via the (b)(6) study, a (b)(6) male patient with a history of smoking (previous) and mandibular cancer underwent balloon-assisted coil embolization of an unruptured anterior communicating artery (acom) aneurysm on (b)(6) 2019 and experienced a thromboembolic event during the procedure.Integrilin/aspirin was administered, and neuroform atlas stent (stryker) was implanted.The patient was asymptomatic; the thromboembolic event was only observed angiographically.The patient was discharged home with self-care on (b)(6) 2019 with modified rankin scale (mrs) score of 0.Platelet reactivity testing was not performed.The dimensions of the bifurcation aneurysm were as follows: aneurysm height 7.5mm, dome 7.2mm, maximum aneurysm diameter 7.5mm, neck size 5.9mm, and dome-to-neck ratio of 1.2mm.The parent vessel diameter was 1.9mm.Balloon-assisted coil embolization was performed with six cerenovus coils: a 7mm x 13.9cm micrusframe 10 (mfr100713 / l13000), a 7mm x 21cm galaxy g3 (gly120721 / l13249), a 5mm x 10cm galaxy g3 (gly120510 / l12927), a 3.00mm x 8.00cm galaxy g3 mini (glm930080 / l13613), a 2.00mm x 4.00cm galaxy g3 mini (glm920040 / l11233), and a 2.00mm x 3.00cm galaxy g3 mini (glm920030 / l13822) via an sl-10 microcatheter (stryker).There was no microcatheter kickback (loss of access to aneurysm) experienced during the procedure.Heparin was administered during the procedure.In the opinion of the investigator, treatment of the target aneurysm was considered complete, and the study coils were successfully implanted at the target site with 18% angiosuite packing density.Immediate post-procedure modified raymond-roy classification score was class iiia: residual aneurysm with contrast within coil interstices.The reason additional coils were not placed was ¿adequate occlusion/stasis¿.There were no reported study device deficiencies.The complaint coils remain implanted and are thus not available for evaluation.
