Preoperative tumor embolization is a medical procedure that involves blocking the blood supply to a tumor before surgery. The procedure is performed by an interventional radiologist, who uses imaging techniques to guide a catheter (a thin, flexible tube) to the blood vessels that are feeding the tumor. Once the catheter is in place, small particles or a liquid agent are injected into the blood vessels to block the blood flow to the tumor. This causes the tumor to shrink, making it easier to remove during surgery, and can also help to reduce the risk of bleeding during the procedure.
Preoperative tumor embolization is typically used for tumors that are located in or around large blood vessels, such as those found in the liver, lung, or kidney. The procedure can be used for both benign and malignant tumors and can be performed on tumors of various sizes. Some of the most common conditions that may benefit from preoperative tumor embolization include hepatocellular carcinoma, renal cell carcinoma, and lung cancer.
The main advantage of preoperative tumor embolization is that it can help to make surgery safer and more effective. By reducing the size of the tumor and minimizing the risk of bleeding, the procedure can help to improve the outcomes of surgery, including reducing the risk of complications and improving the chances of complete resection (removal) of the tumor. Additionally, preoperative embolization may also increase the chances of being eligible for a less invasive surgical approach.
The procedure is usually performed a day or two before surgery, and it usually takes 1-2 hours. The patient is usually awake during the procedure but may be given a mild sedative to help them relax. Recovery from preoperative tumor embolization is usually quick and patients are able to return to their normal activities within a few days.
There are some risks associated with preoperative tumor embolization, such as bleeding, infection, and injury to the surrounding organs or blood vessels. However, these risks are generally low, and the procedure is considered to be safe.
In conclusion, Preoperative tumor embolization is a medical procedure that involves blocking the blood supply to a tumor before surgery. It's performed by an interventional radiologist, who uses imaging techniques to guide a catheter to the blood vessels that are feeding the tumor. By reducing the size of the tumor and minimizing the risk of bleeding, the procedure can help to improve the outcomes of surgery, including reducing the risk of complications and improving the chances of complete resection of the tumor. Additionally, preoperative embolization may also increase the chances of being eligible for a less invasive surgical approach. However, like any other medical procedure, there are some risks associated with preoperative tumor embolization, such as bleeding, infection, and injury to the surrounding organs or blood vessels. But it's considered to be a safe procedure. It is important to consult with your doctor and discuss the potential benefits and risks of preoperative tumor embolization to determine if the procedure is right for you
