title: Technical report: perirectal abscess drainage--a simple modification in technique using a vascular sheath.
abstract: Two patients with pelvic abscesses underwent fluoroscopic guided transrectal catheter drainage using a simple modification in standard technique. A 9F vascular sheath allows contrast to be instilled through the side port and the seal avoids any leakage back through the sheath. It also provides a safe, quick and precise needle puncture at the selected site.
