Ischemic optic neuropathy in internal carotid artery dissection – A rare clinical presentation

Ischemic optic neuropathy associated with internal carotid artery dissection.

BACKGROUND Ischemic optic neuropathy (ION) is an infarction of the anterior or, less frequently, posterior part of the optic nerve, usually due to a disease of small arteries supplying the optic nerve. Carotid stenosis or occlusions are rare causes, and among them, carotid dissections have been so far reported in only 5 cases. METHODS We describe 4 patients with ION (2 anterior and 2 posterio...

Anterior ischemic optic neuropathy following neck dissection.

BACKGROUND Ischemic optic neuropathy (ION) is a rare but devastating complication of surgery. It has traditionally been associated with intraoperative hypotension in patients with underlying arteriosclerosis. METHODS We present a case of ION following bilateral neck dissections in which there was minimal intraoperative hypotension and preservation of both internal jugular veins. The potential...

A Penetrating Pellet Jeopardizing Internal Carotid Artery

Noninvasive monitoring of internal carotid artery dissection.

BACKGROUND AND PURPOSE Internal carotid artery dissection has increasingly been reported as a cause of transient ischemic attack or stroke. However, scarce data exist on the natural history of the arterial lesions and the temporal profile of recanalization. METHODS We followed 48 patients with 50 angiographically confirmed internal carotid artery dissections by sequential duplex Doppler studi...

Internal carotid artery dissection after childbirth.

A 44-year-old woman developed a left cerebral infarction secondary to internal carotid artery dissection 6 days after childbirth. A cesarean section had been carried out after 14 hours of strenuous unsuccessful labor. Although in the past some authors have implicated oral contraceptives as a cause for carotid dissection, carotid dissection associated with childbirth has not been previously desc...
