Hi there. Micro vascular depression is a surgical procedure to relieve symptoms of nerve compression. It involves surgically opening the skull and exposing the nerve at brainstem, trigeminal neuralgia being treated by inserting a tiny sponge between the trigeminal nerve and superior cerebellar artery. you will need to undergo tests like blood tests electrocardiogram, chest x ray, sign consents, furnish details about allergies, medicines, anesthetic reactions, other preanesthetic precautions like stopping NSAIDs, blood thinners, stop smoking etc. the surgery involves patient preparation, performing a craniectomy, the nerve is exposed at its origin, sponge inserted between the nerve and the vessels and brain is returned to natural position. You would be kept in the ICU post operatively. You might have some discomfort and headaches managed with NSAIDs and opioids. Certain restrictions need to be observed like avoiding driving and sitting, avoid lifting heavy weights and housework, and stop alcohol if taking. Results are usually promising and good success rates. Certain risks include bleeding, infection, blood clots, and anesthesia reactions. Complications possible are stroke, CSF leak, brain swelling etc. Hope it helps. Take care.
