What does "percutaneous" describe?

The term "percutaneous" specifically describes a method of access to the body that occurs through the skin. This can involve the introduction of instruments, needles, or medications that penetrate the skin to reach underlying tissues or organs. The concept encompasses procedures where substances are absorbed into the body through the skin, such as the delivery of certain medications or therapies.

In medical contexts, percutaneous procedures are often associated with less invasive techniques compared to traditional surgical methods, as they can usually be performed with local anesthesia and minimal incisions. This process is pivotal in various medical fields, including dermatology and interventional radiology, where access is needed without major surgical intervention. Understanding this terminology is essential for professionals in healthcare as it relates to treatment methods, patient care, and planning procedures.
