Event Description
|
The physician successfully performed a balloon (subject device) angioplasty of the target basilar trunk lesion to treat 74% proximal stenosed lesion and 79% distal stenosed lesion.Following angioplasty, the first stent was placed across the distal lesion and the second stent was placed to cover the proximal lesion in overlapping fashion.After the procedure, the basilar trunk had 35% residual stenosis.There was no device malfunction and no patient complication noted during the procedure.However, several hours post procedure, the patient had right sided weakness.Imaging demonstrated an ischemic thromboembolic left pontine perforator/lacunar stroke with mild mass effect.The next day, new left cerebellar and vermian infarcts with small right temporo-occipital subarachnoid hemorrhage (sah) were found.The stroke was treated using medical therapy (not specified).The physician stated that the reported stroke related to use of the subject balloon catheter; however, the relations to the stent and the procedure are unknown.
