Perkutane Verfahren: Minimalinvasive, bildgeführte Interventionen

Percutaneous (“through the skin”) procedures access deep structures via needle/catheter puncture rather than open incision. They are a cornerstone of modern minimally invasive medicine.

Core Characteristics

Minimally invasive: Small puncture (2–10 mm) vs. large incision.
Image‑guided: Ultrasound, fluoroscopy, CT, MRI for real‑time targeting.
Local anesthesia ± sedation: Avoids general anesthesia risks.
Outpatient/short stay: Faster recovery, lower cost, less scarring.

Common Examples

Procedure	Purpose	Imaging
Percutaneous biopsy	Tissue diagnosis (liver, lung, kidney, bone)	US, CT
Percutaneous drainage	Abscess, fluid collection, biliary/urinary obstruction	US, CT
PEG (Percutaneous Endoscopic Gastrostomy)	Long‑term enteral feeding	Endoscopy + fluoroscopy
PTCA/PCI	Coronary stenting for CAD	Fluoroscopy (angiography)
PCNL (Percutaneous Nephrolithotomy)	Large kidney stone removal	Fluoroscopy/US
Radiofrequency/Microwave Ablation	Tumor destruction (liver, lung, kidney, bone)	CT, US
Vertebroplasty/Kyphoplasty	Vertebral compression fracture stabilization	Fluoroscopy

Advantages Over Open Surgery

Reduced pain, blood loss, infection risk, hospital stay.
Faster return to function.
Feasible in high‑surgical‑risk patients.

Percutaneous techniques continue to expand across specialties (IR, cardiology, neuro, ortho, urology, GI).
