Event Description

It was reported that a ruptured aneurysm of anterior communicating artery was treated with an embolization coil implant.At the time of positioning the coil implant, the patient was noted to have a change in mental status, which was likely a seizure event.After sedation had been given in addition to seizure medication and patient refrained from actively moving, the physician wished to remove the coil and use a smaller one.The implant detached upon attempted retraction into the microcatheter.The physician left the coil in position and chose to end the procedure and transfer the patient to the intensive care unit given their "decline and neurologic status with recent seizure activity." follow-up angiography was performed, establishing that there was no filling of the aneurysm.It was noticed that the left anterior cerebral artery branch was not filling as it had previously, the cause or suspected cause of which was not stated by the physician.After the procedure, the patient had a stroke, the cause and location of which was not stated.It was related by a hospital employee that it may have been due a coil tail protruding into the parent artery or a piece of guidewire left behind, but the presence of a coil tail or fragment of a device was not mentioned in an operative report obtained from the hospital.The patient was hospitalized for 95 days and released to a care facility on (b)(6) 2021.The patient is said to be following commands and making improvements.
