CLINICAL ISSUE: Craniocervical dissections are among the most common causes of stroke in people aged under 50 years, which is why it is essential to clarify, diagnose, and treat them as quickly as possible. Dissections usually occur spontaneously due to bleeding into the vessel wall. The affected segments are usually the motion segments of the internal cerebral artery (C1 segment) and the vertebral artery (V3 segment). Clinically, there is head and/or neck pain and neurologic symptoms, which can vary according to the localization of the dissection.
PRACTICAL RECOMMENDATIONS: Pathognomonic is the detection of an intramural hematoma due to bleeding into the vessel wall. This can best be detected by magnetic resonance imaging (MRI) in native, fat-saturated T1 sequences (black-blood sequence). In addition, contrast-enhanced angiography should be performed using MRI or, alternatively, computed tomography (CT). As there is an increased risk of embolic or hemodynamically induced strokes, prophylactic treatment should be initiated immediately; it remains a case-by-case decision whether antiplatelet agents or oral anticoagulants are chosen for this purpose.
