Vertebrobasilar Insufficiency: Symptoms and Surgical Options - Neurosurgery

More Info

---

Vertebrobasilar insufficiency (VBI) is a condition that arises when there is inadequate blood flow to the posterior circulation of the brain, which is supplied by the vertebral and basilar arteries. This can lead to a range of neurological symptoms, including dizziness, vertigo, headaches, and even more severe manifestations such as weakness or numbness in the limbs. In your case, the symptoms you describe—headaches, dizziness, right ear pain, weakness in the right leg, and episodes of chest pain—are concerning and warrant a thorough evaluation.

Based on the MRI findings you provided, there are several key points to consider:
1. Right Vertebral Artery Hypoplasia: This means that the right vertebral artery is underdeveloped, which can contribute to reduced blood flow. The hypoplasia of the right vertebral artery, combined with the narrowing of the internal carotid artery (ICA) at the supraclinoid and cavernous segments, could exacerbate the symptoms of VBI.

2. Cervical Spine Issues: The protruding disc at the C4-5 level causing mild thecal sac indentation may also contribute to your symptoms. Disc herniation can lead to nerve compression, which might explain some of the neurological deficits you are experiencing, such as weakness and sensory changes in the right side of your body.

3. Sinus Issues: The findings of fluid collection in the sphenoid and maxillary sinuses suggest sinusitis, which could be contributing to your headaches and possibly your dizziness.


Surgical Options
The decision to pursue surgical intervention for VBI or related conditions depends on several factors, including the severity of symptoms, the degree of vascular compromise, and the presence of other treatable conditions (like the cervical disc issue). Here are some potential surgical options:
1. Decompression Surgery: If the cervical disc herniation is significantly compressing the spinal cord or nerve roots, a decompression surgery (like an anterior cervical discectomy and fusion) may be indicated. This could alleviate some of the neurological symptoms you are experiencing.

2. Vascular Surgery: If the vertebral artery hypoplasia and ICA narrowing are deemed significant contributors to your symptoms, vascular surgery might be considered. This could involve procedures to improve blood flow, such as stenting or bypass surgery, although these are less common for vertebral artery issues compared to carotid artery interventions.

3. Management of Sinusitis: If your sinus issues are contributing to your symptoms, addressing them through medical management or surgery (like functional endoscopic sinus surgery) may be beneficial.


Conclusion
Given the complexity of your symptoms and the MRI findings, it is crucial to have a comprehensive discussion with a neurologist or a neurosurgeon who specializes in vascular issues and cervical spine disorders. They can provide a detailed assessment of your condition and recommend the most appropriate treatment options based on the severity of your symptoms and the underlying causes identified in your imaging studies.

In the meantime, it is essential to monitor your symptoms closely. If you experience any worsening of your condition, such as increased weakness, severe headaches, or changes in consciousness, seek immediate medical attention. Your health and safety are paramount, and timely intervention can make a significant difference in outcomes for conditions like vertebrobasilar insufficiency.
