Vertebral Artery Issues: Symptoms and Diagnostic Options - Neurology

Understanding vertebral artery issues can be quite complex, especially when symptoms like pain during swallowing and persistent dizziness are involved. Your situation, where you experience pain in the occipital region while swallowing, combined with ongoing dizziness for nearly three months, warrants a thorough evaluation.
Firstly, it’s important to recognize that the vertebral arteries are crucial for supplying blood to the brain, particularly the posterior circulation, which includes the cerebellum and brainstem. Symptoms related to vertebral artery issues can include dizziness, balance problems, headaches, and even visual disturbances. In your case, the pain during swallowing could suggest irritation or compression of the surrounding structures, potentially involving the vertebral artery or nearby nerves.

Given that you have already undergone carotid ultrasound with normal results, it’s essential to consider further imaging studies to evaluate the vertebral arteries and the posterior circulation of the brain. Here are some diagnostic options:
1. Magnetic Resonance Angiography (MRA): This is a non-invasive imaging technique that provides detailed images of blood vessels. It can help visualize the vertebral arteries and detect any abnormalities such as stenosis (narrowing), dissection (tearing), or other vascular issues. Since you mentioned that you have no significant cardiovascular risk factors (normal cholesterol, blood pressure, and no smoking), MRA is a suitable option as it does not involve radiation exposure.

2. Computed Tomography Angiography (CTA): This is another imaging modality that can provide detailed images of blood vessels. It is often quicker than MRA and can be useful in acute settings. However, it does involve exposure to radiation and contrast material, which may not be ideal for everyone.

3. Cervical Spine MRI: Since you are experiencing pain in the occipital region, it may also be beneficial to evaluate the cervical spine for any disc herniation or other structural issues that could be compressing the vertebral arteries or nearby nerves.
4. Transcranial Doppler (TCD): This ultrasound technique can assess blood flow in the major cerebral arteries and may provide additional information about the hemodynamics of the vertebral arteries.

5. Neurological Evaluation: Given your symptoms, a comprehensive neurological examination is crucial. A neurologist can assess your symptoms in detail and may recommend additional tests based on their findings.

In summary, considering your symptoms and the normal results from previous tests, I would recommend pursuing an MRA of the cervical and cranial vessels as your next step. This will provide valuable information regarding the vertebral arteries and help rule out any significant vascular issues. If the MRA is inconclusive and your symptoms persist, further evaluation with a cervical spine MRI or CTA may be warranted.

It’s also important to maintain open communication with your healthcare provider about your symptoms and any changes you experience. If your symptoms worsen or new symptoms arise, such as severe headaches, visual changes, or neurological deficits, seek immediate medical attention. Early intervention can be crucial in preventing complications associated with vertebral artery issues.
