Surgical treatment of spontaneous internal carotid dissection.
Spontaneous dissection of the internal carotid artery is rarely submitted to surgery. We report a case successfully operated on with complete restoration of the cerebral blood flow. A 43-year-old male was admitted to our hospital 10 days after an episode of amaurosis fugax of the left eye, left sided headache and paresis of the right arm of a few hours duration. A diagnosis of dissection of the left internal carotid artery was made by duplex and triplex ultrasound examination and was confirmed by cerebral arteriography in contrast to magnetic resonance angiography which was misleading. Due to the slow arterial flow from the right to the left cerebral hemisphere through only the posterior communicating arteries we envisaged the possibility of a cerebral infarction if the dissection were to be extended. For this reason a surgical procedure was performed by excising the dissected segment and inserting a venous graft for the re-establishment of the arterial flow. Surgical treatment of spontaneous internal carotid dissection should be considered very carefully when the clinical and laboratory findings suggest the possibility of an impending stroke.
