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.
