Superior cerebellar artery infarction and vertebral artery dissection.

Superior cerebellar artery infarction and vertebral artery dissection.

Isolated superior cerebellar artery infarction is rare, and the mechanism is often not readily apparent. We describe a patient with an isolated superior cerebellar artery infarction resulting from an ipsilateral vertebral artery dissection. Angiography demonstrated intraluminal clot in the superior cerebellar artery, suggesting artery-to-artery embolus as a mechanism of this uncommon stroke syn...

Vertebral artery dissection and cerebellar infarction following chiropractic manipulation.

Vertebral artery dissection (VAD) associated with chiropractic cervical manipulation is a rare but potentially disabling condition. In this report, we present a young patient manifesting with repeated vertigo. Owing to the initial misdiagnosis, the patient later developed cerebellar stroke with inability to stand or walk. Vertigo and disequilibrium are the usual presenting symptoms of this cond...

Extracranial vertebral artery dissection

Vertebral artery dissection (VAD) is not uncommon in the young adult population. Owing to the various clinical manifestations; the diagnosis of VAD mainly depends on imaging examinations. Ultrasound has found an increasingly wide utilization in the diagnosis of VAD because of the continuous improvement in the resolution of ultrasonic instruments and accessibility.We retrospectively collected th...

Extracranial vertebral artery dissection.

Vertebral Artery Dissection

Background and Purpose: In this study we analyzed the value of ultrasound examination for diagnosis of vertebral artery dissection. Methods: The vertebrobasilar arterial system was assessed in 14 patients using transcranial and extracranial pulsed-wave Doppler and duplex sonography. Results: The dissections were verified by angiography (in 1 patient), magnetic resonance imaging (in 5), or both ...
