Percutaneous procedures involve accessing a specific area within the body using a needle or catheter that is inserted through the skin. This minimally invasive approach is often used for diagnostic or therapeutic purposes, such as biopsies, drainage of fluids, or delivering medication directly into a tumor. Percutaneous procedures are commonly performed under imaging guidance, such as ultrasound or fluoroscopy, to ensure accuracy and safety. This approach typically results in faster recovery times, less pain, and lower risk of complications compared to traditional open surgery.
