percutaneous describes procedures, access, or drug delivery passing through the skin without surgical incision (e.g., needle sticks, catheters). Percutaneous (adj.) refers to methods effecting entry, intervention, or absorption via skin puncture using needles, wires, sheaths, or devices, often employing the Seldinger technique (needle → guidewire → catheter over wire), minimizing invasiveness compared to open surgery; examples span vascular access (angiography/PCI), biopsies, drainages (nephrostomy), gastrostomy (PEG), nephrolithotomy (PCNL), and transdermal patches.
latin
• Per-: Latin per = “through.”
• cutaneous: Latin cutis = “skin” (PIE keu(t)- “to cover, conceal”).
• Coined: 1862 as percutaneus (“through the skin”).
• Pronunciation: /ˌpɜr kjuˈteɪ ni əs/ (“per-kyoo-TAY-nee-us”).

Risks: Bleeding, infection, vessel injury (mitigated by ultrasound).[3]
One-Sentence Summary Percutaneous (Latin per cutem “through skin,” coined 1862), denotes needle-puncture access (ICD-10-PCS approach “3”) for minimally invasive procedures like PCI or biopsies, contrasting open surgery via Seldinger method.[2][1][3]
