TRAUMATIC CAROTID AND VERTEBRAL ARTERY DISSECTION IN A PROFESSIONAL JOCKEY - A CAUTIONARY TALE

Jockeys accept bony fractures and soft tissue injuries as occupational hazards. An average National Hunt jockey falls once in ten races with an injury rate of 4.25%(1). Head injury is a common cause of morbidity and the benefit of helmets is well recognized. Neck injuries are also common and usually musculoskeletal. Although rare, trauma to the neck arteries may go unnoticed yet have catastrophic consequences. Internal tears can allow arterial blood to dissect the layers of the arterial wall and obstruct the lumen. Severe obstruction may lead to cerebral ischaemia and infarction. An appreciation of the early clinical signs caused by this process may allow effective intervention. We report a case which illustrates these points.
