A cerebrospinal fluid leak can be either cranial or spinal, and these are two different disorders. The spinal meninges of the central nervous system impacted by CSF leakĪ cerebrospinal fluid leak ( CSF leak or CSFL) is a medical condition where the cerebrospinal fluid (CSF) surrounding the brain or spinal cord leaks out of one or more holes or tears in the dura mater. A blood clot, a bad reaction to the anaesthetic and blood loss can all be life-threatening.Medical condition Cerebrospinal fluid leak accidental damage to the nerves when they're moved during surgeryĪs with all types of surgery, there's a risk of dying during or after lumbar decompression surgery, although this is rare.accidental damage to the blood vessels that supply the spinal cord with blood. leaking of spinal fluid (incidental durotomy).bleeding inside the spinal column (extradural spinal haematoma).Nerve injuries and paralysis can be caused by a number of different problems, including: Paralysis is an uncommon, but serious, complication that can occur as a result of lumbar decompression surgery. Some patients who have lumbar decompression surgery will develop new numbness or weakness in one or both legs as a result of the operation. In some cases, a red sore can develop over the forehead or chin, which could last several days. The anaesthetist will check regularly to make sure this isn't causing any problems, but many people will wake up with a slightly puffed up face. Facial sores and loss of visionĪs you're positioned face down during lumbar decompression surgery, you'll be resting on your forehead and chin while the operation is carried out. However, small leaks can sometimes only become apparent after the operation, causing problems such as a headache and the wound to leak. Further surgery to repair this may be needed. If this is discovered during the operation, it will be patched and repaired. Leakage of cerebrospinal fluidĭuring lumbar decompression surgery, there's a risk of accidental damage to the lining of the nerve, which can lead to the leakage of cerebrospinal fluid (CSF). However, further corrective surgery may be required in a small number of cases. In most cases, the repair is successful and no further problems or issues arise. Your surgeon will be aware of the risk of a dural tear, and if it does occur they will close the tear with stitches. If the tear isn't identified and repaired at the time of surgery, it can lead to cerebrospinal fluid (CSF) leaking after the procedure. The dura is a watertight sac of tissue that covers the spinal cord and spinal nerves. There's a risk of a dural tear occurring during all types of spinal surgery, including lumbar decompression surgery. The risk of developing a blood clot can be significantly reduced by staying active during your recovery or wearing compression stockings to help improve your blood flow. This is where a piece of the blood clot breaks off and blocks one of the blood vessels in the lungs. This is known as deep vein thrombosis (DVT).ĭVT can cause pain and swelling in your leg and, in rare cases, may lead to a serious problem called a pulmonary embolism. There's a risk of developing a blood clot after lumbar decompression surgery, particularly in your leg. Infection can be more likely in patients who have diabetes or use steroids. It can usually be treated successfully with antibiotics. One of the most common complications is an infection where the incision was made. However, you can reduce your risk of scarring by doing regular exercises as advised by your physiotherapist after surgery. Unfortunately, there's no effective treatment for scarring around the nerves. Repeat operations have a higher risk of complications than first-time operations. Non-surgical treatments, such as physiotherapy, will usually be tried first if your symptoms recur, but further surgery may sometimes be needed. Scarring around the nerves can also sometimes develop after surgery, which can cause similar symptoms to nerve compression. Recurrent symptoms can be caused by a weakened spine, another slipped disc, or the formation of new bone or thickened ligament that puts pressure on your spinal cord. However, some people continue to have symptoms after surgery, or develop symptoms again within a few years of surgery. Lumbar decompression surgery is generally effective in relieving symptoms such as leg pain and numbness. Like all surgical procedures, lumbar decompression surgery carries some risk of complications.
