We respectively analyzed all the central nervous system complications that occurred after cardiac catheterization through a femoral route at our institution over a 3 1/2 year period.Thirteen patients were identified as having central nervous system complications.Using defined criteria, posterior circulatory events still accounted for at least 54%of central nervous system complications.The preponderance of posterior circulatory events is apparently independent of the route of catheterization. Furthermore,given the array of neurological symptoms and there often complete resolution,we feel it is unlikely that embolism is the sole pathophysiological mechanism involved in these events. |
