Abstract

Spontaneous intracranial artery dissection (SIAD), leading to occlusion or stenosis of arterial lumen is a frequent but less studied cause of ischemic stroke especially in young adults. We studied 17 patients (10 men, 7 women, mean age 27.5 +/- 8.5 years) with SIAD. All the patients have undergone magnetic resonance imaging of the head, magnetic resonance angiography (MRA) (in 16 patients--follow-up MRA), 1 patient--conventional cerebral angiography. SIAD was located in the middle cerebral artery (MCA, 14 patients); posterior cerebral artery (PCA, 2 patients) and basilar artery (BA, 1 patient). Fifteen patients (88%) with SIAD developed ischemic stroke, 2 patients (12%)--a transient ischemic attack (TIA). The appearance of the local brain ischemia symptoms was combined with headache in 93% cases. The course of ischemic stroke was favorable in most cases with complete or good functional recovery in 66% of patients. A fatal outcome was observed in 1 patient (7%) with massive brain infarct. The initial cerebral angiography carried out in most cases (76%) within 3 weeks after the disease onset revealed occlusion (71%) or stenosis (29%) of corresponding cerebral arteries (MCA, PCA, BA). The last cerebral angiography conducted in 90%...Continue Reading
