    Abstract:
    BACKGROUND: The purpose of this study is to demonstrate the feasibility, safety, and success of percutaneous paracoccygeal catheter drainage of deep pelvic abscesses using a combination of sonography and fluoroscopic guidance. METHODS: From April 2005 to December 2006, under sonography and fluoroscopic guidance, sixteen patients with deep pelvic abscess underwent percutaneous paracoccygeal drainage. The causes of pelvic abscesses were post-operative complications. The patient was in prone position; the puncture site was first evaluated with sonography. After local anesthesia, a thin needle (22 G) was positioned along the lateral margin of the coccyx to avoid an eventual injury of sciatic nerve or vessels into the deep pelvic abscess under sonography guidance. Small dose of contrast was injected under fluoroscopy to verify the needle. With Seldinger technique catheters were placed for drainage. Catheter drainage was maintained for 9-40 days. Patients underwent clinical follow-up and subsequent imaging as necessary. RESULTS: Neither significant complications nor technical failures were observed. A complete resolution of the abscess was achieved in 14 patients, and significant resolution of abscess was also observed in the other 2 patients. CONCLUSIONS: Sonography and fluoroscopic guided percutaneous paracoccygeal drainage is safe, feasible and efficient approach in the treatment of deep pelvic abscess.
