Minimally invasive herniated disc surgery is generally minimally invasive lumbar herniated disc surgery. Any surgery has certain risks, and minimally invasive herniated disc surgery is no exception. After rigorous pre-operative evaluation, under the operation of professional doctors, the relative risks are small, but not all patients, and the possible risks mainly include nerve damage, infection, and vascular injury. 1. Vascular injury: minimally invasive surgery for lumbar disc herniation requires the use of an intervertebral foramenoscope to remove the protruding lumbar discs. The surgery carries a certain degree of risk, which may injure the veins between the lumbar vertebrae and cause hematoma and local compression, which can easily cause discomfort such as lumbar pain, numbness of the legs, leg pain and other uncomfortable symptoms. 2. Infection: Minimally invasive surgery for lumbar disc herniation requires the patient’s superficial skin to be cut in order to remove the protruding lumbar disc, and if the patient doesn’t pay attention to the hygiene and cleanliness after the surgery, it is easy to cause the risk of infection. 3. Nerve damage: If the patient accidentally damages the nerves during the surgery, it is easy to cause lower limb weakness, numbness, muscle atrophy, limb movement restriction, etc. If the patient accidentally damages the spinal cord, it is easy to cause infection. If the spinal cord is inadvertently damaged, there is a risk of paraplegia. Minimally invasive surgery for lumbar disc herniation carries certain risks, and it is recommended to strictly follow the doctor’s instructions and perform the surgery under the doctor’s guidance, and also pay attention to the daily care after the surgery to avoid secondary infections, and it is not recommended that the patient overwork after the surgery to avoid aggravating the condition.
