title: [Value of the transgluteal approach under CT-guidance for percutaneous interventional image guided procedures].
abstract: OBJECTIVE
  To assess the CT-guided transgluteal approach for percutaneous interventional image guided procedures.
  
  
  METHODS
  CT guided transgluteal approach through the greater sciatic foramen was used for diagnostic procedure (CT guided needle biopsy of presacral masses n=5) or percutaneous treatment (aspiration n=4, and drainage n=10) in 19 patients, mean age 58 years (age range 20-86).
  
  
  RESULTS
  No technical failure occurred. A histological diagnostic was obtained in all diagnostic procedures. The success rate for therapeutic procedures was 87% and allowed to postpone surgery in 2 cases. In 2 patients a small pelvic hematoma occurred after catheter placement, but remained without consequence. Recurrences of collection occurred in 2 cases, one treated medically and the other surgically. Two patients suffered from transient deep pelvic pain, which resolved after catheter removal.
  
  
  CONCLUSIONS
  CT-guided percutaneous transgluteal procedures may be successfully performed in patients who cannot undergo trans-perineal, trans-rectal or trans-vaginal approach and is a safe and effective diagnostic and therapeutic option.
