Vertebral Artery Dissection (VAD)

Vertebral Artery Dissection (VAD) is a condition where a tear occurs in the inner lining of the vertebral artery, leading to various symptoms and potential complications. In this comprehensive guide, we will break down the types, causes, symptoms, diagnostic tests, treatments, medications, and surgical options associated with Vertebral Artery Dissection in a clear and simple language.

14. Blood Pressure Monitoring: Continuous monitoring to detect fluctuations.
15. Neck X-rays: To identify any abnormalities.
16. Genetic Testing: Especially in cases of suspected genetic predisposition.
17. Electromyography (EMG): Measures muscle response to nerve stimulation.
18. Transcranial Doppler Ultrasound (TCD): Assesses blood flow in the brain.
19. Nuclear Medicine Scan: Detects areas with reduced blood flow.
20. Functional MRI (fMRI): Evaluates brain function during specific tasks.

Treatments:

Treatment approaches for Vertebral Artery Dissection aim to prevent complications and manage symptoms. Here are 30 common treatments:

1. Anticoagulant Medications: To prevent blood clots.
