What does "percutaneous" refer to in medical procedures?

The term "percutaneous" specifically denotes procedures that are performed through the skin, often utilizing minimally invasive techniques. In medical practice, this approach is commonly used to describe various techniques such as the insertion of needles or catheters for diagnostic or therapeutic purposes without the need for large incisions. For example, percutaneous procedures may include taking biopsies, placing central venous catheters, or performing certain types of interventions like angioplasty.

This concept benefits patients by minimizing trauma, reducing recovery times, and often decreasing the risk of complications associated with more invasive surgical procedures.
