Horner’s Syndrome due to a Spontaneous Internal Carotid Artery Dissection after Deep Sea Scuba Diving

الملخص EN

Internal carotid artery dissection (ICAD) is a rare entity that either results from traumatic injury or can be spontaneously preceded or not by a minor trauma such as sporting activities.

It represents a major cause of stroke in young patients.

The diagnosis should be suspected with the combination of Horner’s syndrome, headache or neck pain, and retinal or cerebral ischaemia.

The confirmation is frequently made with a magnetic resonance angiography (MRA).

Although anticoagulation with heparin followed by vitamin-K-antagonists is the most common treatment, there is no difference in efficacy of antiplatelet and anticoagulant drugs at preventing stroke and death in patients with symptomatic carotid dissection.

We describe a patient with ICAD following deep sea scuba diving, who presented with Horner’s syndrome and neck pain and was successfully treated with anticoagulants.
