What are the risks of surgery for ligamentum flavum thickening and spinal stenosis?

The risks of surgery for spinal stenosis caused by thickening of the ligamentum flavum include bleeding, infection, and nerve damage. Surgery is an effective method for treating spinal stenosis caused by thickening of the ligamentum flavum, mainly through laminectomy, spinal canal decompression, and interbody fusion to relieve symptoms.

1. Bleeding is a common risk during surgery, especially since there are abundant blood vessels around the spinal canal. Intraoperative operation may damage blood vessels and cause heavy bleeding. Preoperative evaluation of the patient's coagulation function, and delicate intraoperative operation and hemostasis techniques are the key to reducing the risk of bleeding.

2. Infection is a complication that needs to be watched out for after surgery, including incision infection and intraspinal infection. Strict disinfection before surgery, aseptic operation during surgery, and reasonable use of antibiotics after surgery can effectively reduce the incidence of infection.

3. Nerve injury is a serious risk during surgery, which may lead to paresthesia, decreased muscle strength, or even paralysis. Intraoperative nerve monitoring technology, delicate anatomical operations, and close observation of nerve function changes after surgery are important measures to prevent nerve injury.

Surgery for yellow ligament thickening and spinal stenosis needs to be performed under the guidance of a professional doctor. The patient's condition should be fully assessed before the operation, the appropriate surgical method should be selected, the operation should be performed delicately during the operation, and close observation should be performed after the operation to minimize the surgical risks and ensure the patient's safety.
