The risks of foramen ovale surgery can include infection, recurrence, nerve damage or bleeding, and sequelae of foramen ovale surgery. 1. Infection: Patients may develop wound infection and wound edema when they do not actively change the medication after surgery. 2. Recurrence: When the surgical result is poor, it may be caused by incomplete decompression during the operation or inappropriate surgical indications, and there is a possibility of recurrence after intervertebral foramenoscopy surgery. 3. Nerve damage or bleeding: It may damage the neighboring nerves and blood vessels, as well as the organs, and inadvertent puncture may lead to intestinal or ureteral injury. 4. Sequelae of laminectomy: although the trauma of laminectomy is small, the normal lumbar structure is still damaged, and almost all patients have a certain degree of lumbar pain after the operation, especially when the pain is more obvious during activities. Patients should have a detailed examination before the operation, and choose a regular hospital for the operation can avoid many sequelae or risks.
