Video Summary

The video is a presentation by Susanna Skoccolic on cerebrovascular zebras. Skoccolic discusses three rare cerebrovascular conditions: cavernous carotid fistulas, Bowhunter's syndrome, and spinal dural arteriovenous fistulas. She explains that cavernous carotid fistulas are abnormal connections between the venous cavernous sinus and the internal carotid artery. These fistulas are often mistaken for other conditions such as conjunctivitis or blepharitis, but can be diagnosed with imaging techniques like MRI and angiography. Treatment options for cavernous carotid fistulas include surgical repair or endovascular embolization.<br /><br />Bowhunter's syndrome is a rotational vertebral artery occlusion syndrome. It occurs when there is dynamic compression of the vertebral artery during head rotation. This condition is usually caused by osteophytes or atlantoaxial hypermobility. Symptoms include vertigo, nystagmus, and sensory motor disturbances. Diagnosis is made through a detailed history, physical examination, and imaging techniques like angiography. Treatment options include surgery to decompress or stabilize the vertebral artery.<br /><br />Spinal dural arteriovenous fistulas are abnormal connections between an artery and a vein located near the dura. These fistulas interfere with the normal spinal cord circulation, causing symptoms like lower extremity weakness and bowel and bladder dysfunction. Diagnosis is made through MRI and angiography, and treatment involves surgery or endovascular embolization. Skokolik emphasizes the importance of early diagnosis and treatment for these conditions to prevent further deterioration and maximize chances of recovery.
