The patient was undergoing a large aneurysm pipeline procedure using a neuron max 6f 088 long sheath (neuron max).During the procedure, the physician had difficulty inserting the neuron max and used a large dilator to pre-dilate the vessel and then smoothly inserted the neuron max in the patient; however, the physician noticed that the marker band of the neuron max fell off and traveled up to the m1 vessel in the middle cerebral artery and became lodged.After several unsuccessful attempts to retrieve the marker band using another manufacturer's device, the physician decided to use a stent to keep the marker band in place since the patient's blood flow in the brain did not seem to be disrupted by the marker band.During the early morning hours of the next day, the patient demonstrated stroke signs of right-sided hemiplegia.The patient was brought into the angio suite and there was no sign of a large vessel occlusion.Since the patient's stroke, post-procedure, the patient was being treated and had hemiplegic speech impairment.The patient's condition improved from the initial onset of the stroke symptoms but the patient was still experiencing right-sided hemiplegia and was aphasic.As of 12/01/2015, the patient is still recovering and is doing slightly better.
