Spontaneous petrous carotid artery occlusive dissection treated by local fibrinolysis and stent deployment.

This paper reports a case of local thrombolytic therapy followed by stenting of the petrous carotid in a young woman with recurrent transient ischemic attacks from spontaneous dissection. A total of four overlapping balloon-expandable stents were delivered in two different sessions one month apart. The procedure resulted in a potentially efficacious treatment for the prevention or reduction of cerebral damages from ischemia. At followup three months later the patient was symptomfree and DSA revealed a delayed proximal small pseudoaneurysm and a carotid-cavernous fistula. At one year follow-up the patient was still symptom-free with unmodified findings at cerebral angiography.
