Clinical import of Horner syndrome in internal carotid and vertebral artery dissection.

چکیده
OBJECTIVE To study the prognostic importance of Horner syndrome (HS) in patients with internal carotid artery dissection (ICAD) or vertebral artery dissection (VAD). METHODS In this observational study, characteristics and outcome of patients with ICAD or VAD from the CADISP (Cervical Artery Dissection and Ischemic Stroke Patients) database were analyzed. The presence of HS was systematically assessed using a standardized questionnaire. Patients with HS (HS+) were compared with HS- patients. Crude odds ratios (ORs) with 95% confidence intervals and ORs adjusted for age, sex, center, arterial occlusion, bilateral dissection, stroke severity, and type of antithrombotic treatment were calculated. RESULTS We analyzed 765 patients (n = 496 with ICAD, n = 269 with VAD, n = 303 prospective, n = 462 retrospective). HS was present in 191 (38.5%) of the patients with ICAD and 36 (13.4%) of the patients with VAD (p < 0.001). HS+ ICAD patients presented less often with stroke or TIA (p < 0.001), less often had bilateral (p = 0.019) or occlusive (p = 0.001) dissections, and had fewer severe strokes (p = 0.041) than HS- ICAD patients. HS+ ICAD patients had a better functional 3-month outcome than those without HS (ORcrude = 4.0 [2.4-6.7]), and also after adjustment for outcome-relevant covariates (ORadjusted = 2.0 [1.1-4.0]). HS+ ICAD patients were less likely to have new strokes than HS- ICAD patients (p = 0.039). HS+ VAD patients more often had vessel occlusion (p = 0.014) than HS- patients but did not differ in any of the other aforementioned variables. CONCLUSION In patients with ICAD, HS is an easily assessable marker that might indicate a more benign clinical course. HS had no prognostic meaning in patients with VAD.

Growing Evidence about the Relationship between Vessel Dissection and Scuba Diving
Carotid and vertebral artery dissection are relatively frequent and risky conditions. In the last decade, different patients with extracranial (and in 1 case also intracranial) dissections associated with the practice of scuba diving were reported. The connection between the two conditions has not been fully explained so far. In the present article, we report the case of a patient presenting wi...
متن کاملA case of aberrant bilateral vertebral arteries orgin presenting with right VA dissection
Background: Knowledge of variations in the origin of vertebral artery (VA) is indispensable to vascular surgeons. Aberrant origin of vertebral artery on either side is an uncommon finding. There are unilateral and bilateral variability in VA origin. Case presentation: We present a case of vertebral artery dissection who was found to have bilateral VAs aberrant origin. The right VA took origin ...

BACKGROUND Incidence rates for internal carotid artery dissection (ICAD) have been reported to be 2.6 to 2.9 per 100,000, but reliable epidemiologic data for vertebral artery dissection (VAD) are not available. OBJECTIVE To determine the incidence rate of cervical artery dissection (CAD) in a defined population. METHODS With IRB approval, we used the medical record linkage system of the Roc...

Surgical Position, Cause of Extracranial Internal Carotid Artery Dissection, Presenting as Pourfour Du Petit Syndrome: Case Report and Literature Review.
Dissection of the internal carotid artery is a rare cause of stroke overall, but causes 22% of strokes in younger patients. A common clinical presentation is as Claude Bernard Horner syndrome. We report a craniotomy with 30 degrees rotation of the neck (standard position) in a patient with no major risk factors for carotid dissection, who showed a Pourfour du Petit syndrome due to a dissection ...
