Abstract First symptoms and initial clinical, ultrasonographic and neuroradiological findings ascertained a mean of 5.6 days (SD = 5.6 days), 7.7 days (7.0), and 11.2 days (8.0) after symptom onset were analysed in 44 patients who suffered a spontaneous internal carotid artery dissection (ICD) verified by magnetic resonance imaging, angiography, or both. Common symptoms signalling dissection were unilateral headache in 68\%, transient ischaemic attack in 20\%, and cerebral infarction in 9\%. Severe pain preceded cerebral ischaemia by more than 3 days in 60\% of those patients who eventually suffered a stroke. However, only 2 were admitted because of pain alone and 33 for evolving neurological deficits. During the first month, ipsilateral severe headache occurred in 89\%, neck pain in 36\%, ipsilateral cerebral ischaemia in 82\%, ocular ischaemia in 16\%, oculosympathetic palsy in 48\%, and cranial nerve palsy in 5\%. Recent "trivial" head or neck trauma was elicited in 41\%. Doppler and duplex sonography confirmed the clinical suspicion of ICD in 91.5\% and in 96\% of those with a significant stenosis or occlusion. MRI demonstrated a thickened vessel wall in all 33 imaged carotid dissections and a mural haematoma in 30. None of the 32 patients who received anticoagulant treatment subsequently deteriorated. Monitoring anticoagulant treatment with ultrasonographic follow-up studies demonstrated recanalization in 70\% and persistent occlusion in 30\%. The results demonstrate that familiarity with the initial symptoms, especially headache, and performance of an ultrasonographic study without delay are the cornerstones of an early diagnosis.(ABSTRACT TRUNCATED AT 250 WORDS)
