We describe a case of a middle-aged Caucasian pilot who presented to us with a painless left Horner's syndrome due to a focal dissection of the infra-petrous portion of the ipsilateral internal carotid artery. He did not suffer symptoms of cerebral ischemia at the time of onset, or during the following 2 yr. The Horner's syndrome persisted unchanged throughout follow-up. Serial magnetic resonance angiograms showed some regression of the focal stenosis at 12 mo, with no further change over the next 10 mo. The literature suggests that the risk of stroke after onset of dissection is usually in the first month, and the risk of recurrence of dissection is about 1% per year after the first year. Our patient was prescribed aspirin 300 mg.d-1, and certified to fly as or with a co-pilot commencing 1 yr after onset of his symptoms.

Dissection of internal carotid artery is an unusual cause of stroke. It generally affects the extracranial portion of the vessel, rarely the intra-cranial portion and exceptionally both sections simultaneously. We present two cases of spontaneous dissection with extra and intra-cranial involvement. Two females, 46 and 36 years old, presented as stroke of the right internal carotid (ICA) associated with headaches and ipsilateral Horner's syndrome. An echo-Doppler was done on the first patient, which turned to be normal, and carotid angiography was done to both patients. The first patient showed a filiform stenosis of the right ICA that ran from the origin to the carotid siphon. The second patient showed a longitudinal stenosis of the right ICA 2 cm from the origin, which ended in an obstruction of the terminal branches. The control angiographs at five and six months respectively, showed partial re-channelling or complete re-channelling. The first case was treated with anti-aggregants and the second with anticoagulants. There were no new episodes in either cases. Dissection of the ICA usually only affects the extracranial portion of the artery, stopping in the petrous portion. We do not know why dissection also affected the intra-cranial section of the artery in these two cases.

Enlargement of the thyroid is common, especially in areas of endemic iodine deficiency. Substernal enlargement of a goitre can cause compression of several mediastinal structures. As a consequence of tracheal compression and tracheomalacia, syndromes of chronic respiratory distress occur and intercurrent upper respiratory infections may lead to acute respiratory failure. Superior vena cava syndrome secondary to compression by a substernal goitre may be complicated by venous thrombosis. Although dysphagia is the most frequent oesophageal symptom of a substernal goitre, upper gastrointestinal bleeding from 'downhill' oesophageal varices may be an initial presentation. Arterial compression or thyrocervical steal syndrome by large substernal goitres occasionally cause cerebral hypoperfusion and stroke. Recurrent and phrenic nerve palsies, as well as Horner's syndrome, occur secondary to non-malignant mediastinal goitres and may resolve after surgery. Substernal goitres rarely cause therapy-resistant pleural effusions, chylothorax and pericardial effusion. In conclusion, although cervical goitres are easily recognised, the initial presentation of mainly substernal goitres may be unusual.

Patients with carotid artery disease may present with monocular, ipsilateral ocular symptoms, and signs that can herald a devastating stroke. Asymptomatic retinal emboli, transient monocular visual loss, and central retinal artery occlusion are the most common. Venous stasis retinopathy and ocular ischemic syndrome are associated with severe hypoperfusion of the eye and usually reflect severe carotid occlusive disease. Embolic ischemic optic neuropathies and compression of the intracranial optic nerve by supraclinoid carotid arteries remain debated. Third-order Horner's syndrome and eye pain are common in carotid artery disease, particularly carotid dissection; carotid artery disease, however, is an uncommon cause of ocular motor nerve palsy. Several recent publications have highlighted the prognosis and management of patients with carotid artery occlusive disease, and have emphasized the role of the ophthalmologist in early diagnosis and prevention of further cerebral and systemic complications.

A 52-year-old man with diabetes mellitus, hyperlipidemia and smoking habit, experienced transient ischemic attacks (TIAs) with symptoms of left orbital pain, left blepharoptosis and hoarseness lasting for five minutes on March 10, 1997. Subsequently, the same symptoms repeated once or twice daily. On March 28, he had dysphagia, numbness and disturbance of pain and temperature sensation (segmental dissociated sensory disturbance) on the right side of the body above the level of the Th10, the right upper limb and face. The deficits persisted for more than 24 hours. Angiographic studies revealed an occlusion of the left vertebral artery immediately after branching of the posterior inferior cerebellar artery. MRI demonstrated a hyperintense lesion on MRI T2 weighted image in the left lateral medulla. About three months after the completed stroke, he had six episodes of TIAs of left Horner's sign and hoarseness. To our knowledge, this is the rare case that had frequent TIAs presenting the Wallenberg syndrome before and after the onset of lateral medullary infarction. We speculate that the TIAs resulted from microembolism from the proximal end of occluted left vertebral artery and failure of the microcirculation in and around the lateral portion of the medulla oblongata.

From 1990 to 1997, June, 296 patients (156 males and 140 females), aged 16 to 45 years, admitted in the Neurology Department of the University Hospital of Nancy (F) for ischemic stroke, were prospectively evaluated according to a standardized analysis of anamnestic and clinical data, angiography (90 p. 100 of cases), TEE (78 p. 100), hemostasis. Women were younger (mean age = 34.82 y) than men (36.87 y; p = 0.003), with a peak in the 4th decade. Clinical event was a TIA in 14.2 p. 100, a stroke in 51.7 p. 100; it concerned the anterior circulation in 64.5 p. 100, posterior circulation in 25 p. 100, multiple territories in 10.5 p. 100. History of TIA, cervical-cranial pain or Horner syndrome suggestive of dissection, pregnancy or post-partum were found respectively in 60 (20.3 p. 100), 34 (11.1 p. 100) and 13 (9.3 p. 100) cases. Risk factors concerned 87.2 p. 100 of patients, mainly smoking (55.1 p. 100), oral contraceptive (53 p. 100), hyperlipemia (35 p. 100), and were more frequent in case of atheroma and lacunar stroke (p < 0.0000). Etiology, according to TOAST classification, was: atheroma (8.4 p. 100), cardioembolism (8.7 p. 100), small-artery disease (7.1 p. 100), dissection (15.5 p. 100), other determined causes (11.1 p. 100), multiple causes (5.7 p. 100), undetermined cause (34.8 p. 100). Septal pathology was found 34 times. Patients whose stroke remained unexplained were younger (33.7 y vs 37.7, p = 0.002), had less risk factors (p < 0.0000), had more TIA (p = 0.005), more often in the carotid territory (p = 0.008), had a better prognosis (p = 0.01), and showed more often emboli at angiography (p = 0.001). During a mean follow-up of 33 months (median = 19), 21 recurrent strokes occurred and 6 patients died. 134 (46 p. 100) patients had no sequelae, 101 (34.7 p. 100) minor disability, 42 (14.4 p. 100) major sequelae. These results, compared to the main studies of the literature, suggest the interest of common definition criteria and classification of etiologies. In practice, hierarchisation of investigations may be proposed, and vascular risk factors should be tracked in young patients. In patients whose stroke remains unexplained, further studies, as atrial vulnerability, are needed.

The purpose of this review is to increase the awareness of internal carotid artery dissection (ICAD), a potentially serious and probably underdiagnosed condition. ICAD is a not uncommon cause of stroke in young patients. ICAD may occur spontaneously or as a result of trauma. However, the "spontaneous" dissection is often preceded by a trivial trauma. The typical patient presents with ipsilateral headache or neck pain, ipsilateral Horner's syndrome and delayed ischemic symptoms from the ipsilateral hemisphere or retina. Conventional angiography, the gold standard for diagnosis, tends to be replaced by non-invasive diagnostic methods. There are no evidence-based guidelines for therapy although anticoagulation is most commonly used. The references are selected from the Medline database for the years 1966-1997.

Horner syndrome is defined as homolateral miosis, ptosis and enophthalmus, and occurs after a lesion of central or peripheral sympathetic pathways. The syndrome is mentioned as side effect for example with dysraphias, the Wallenberg syndrome, ischemic stroke of the middle cerebral artery, mediastinal tumors or iatrogen after pneumothorax interventions. We recently observed a patient with a transient significant miosis, without ptosis and enophthalmus, which we interpreted as an incomplete manifestation of a Horner syndrome occurring with spontaneous pneumothorax.

Cervicocephalic arterial dissections (CCAD) are an increasingly recognized cause of ischemic stroke in young adults. Various treatments have been suggested but no controlled trial has ever been performed. Medical treatment has included anticoagulant or platelet antiaggregant therapy. Surgical correction has been proposed for selected patients who have failed medical therapy. Percutaneous balloon angioplasty and stenting have been increasingly used in some patients, although long-term results are unknown. The objective of the study was to review our recent experience with the management and outcome of extracranial CCAD. We identified 27 patients with extracranial CCAD who were evaluated, treated and/or followed by our Stroke Service from September 1995 to August 2001. Clinical presentation, diagnostic evaluation, management, and outcome were reviewed. There were 15 men (56%) and 12 women (44%) with mean ages of 38 and 43 years respectively. Diagnosis was made by cerebral angiography in 15 (56%) patients and by MRI/MRA only in 12 (44%) patients. Twenty-two patients had spontaneous and five had traumatic extracranial CCAD. Most common associated disorders were arterial hypertension (37%) and migraine (26%). One patient presented only with a painful post-ganglionic Horner syndrome, another patient with neck pain and post-ganglionic Horner syndrome, another patient solely with protracted unilateral headaches, three with transient ischemic attacks (TIA), and 21 with ischemic strokes. The internal carotid artery (ICA) was the most frequently involved vessel (63%), followed by the vertebral artery (30%, and multivessel involvement in two patients (7%). Eighteen patients received anticoagulant therapy and nine platelet anti-aggregants. Follow-up extended from 2 to 115 months, with a mean of 58 months. At the end of follow-up, 23 (85%) patients had either no disability or only minor sequelae (modified Rankin score: 0 to 1), and four (15%) patients had moderate limitations (modified Rankin score: 2 to 3). Two patients had a recurrent ischemic stroke, one unrelated to recurrent CCAD, and the other following percutaneous balloon angioplasty/stenting for treatment of a persistent vertebral artery pseudoaneurysm. Most CCAD involved the extracranial ICA. The clinical presentation is variable, most patients having an ischemic stroke or TIAs. The short- and long-term outcome are usually favorable with either anticoagulant or platelet antiaggregant therapy. A medical initial approach to the management of extracranial CCAD is recommended for most patients.
