[Percutaneous transluminal angioplasty for cervical internal carotid artery stenosis: case report].
We encountered one case of right cervical internal carotid artery (ICA) stenosis with ulcerative plaque. The patient was treated using percutaneous transluminal angioplasty (PTA). A 70 year-old man complained of left motor weakness and left hemidysesthesia. CT scan on the day of admission showed no abnormal findings. Angiographical findings revealed a severe right ICA stenosis with ulcerative plaque. We first treated the patient conservatively because of high-positioned carotid bifurcation, bronchial asthma and hypertension. 20 hours after the stroke, left motor weakness gradually worsened and CT scan revealed multiple low-density areas in the right fronto-parieto-occipital watershed region. Because of this, we treated the stenosed ICA by PTCA balloon dilatation catheter, and successfully obtained adequate dilatation with no complications. We propose that PTA of ICA stenosis, as well as PTA of the vertebral region, is a useful method for patients who have conditions which would make surgical operations risky.
