Carotid artery stenting in a patient with spontaneous recanalization of a proximal internal carotid artery occlusion: a case report.

We report here on a rare case of carotid artery angioplasty and stenting in a patient with spontaneous recanalization after complete occlusion of the proximal internal carotid artery (ICA). The patient initially showed severe stenosis at the left proximal ICA on MR angiography (MRA). Digital subtraction angiography (DSA) performed three days after MRA showed complete occlusion of the proximal ICA. The follow-up DSA after four weeks showed recanalization of the ICA, and then carotid artery stenting was successfully performed. There has been no neurologic complication during more than one year follow-up.
