BACKGROUND/AIMS: The goal of our study was to assess the use of real-time computed tomography-fluoroscopy guidance for percutaneous drainage of abnormal thoracic, abdominal, and pelvic fluid collections. METHODOLOGY: The subjects were 32 patients who underwent 36 percutaneous computed tomography-fluoroscopy guided thoracic, abdominal, and pelvic drainage procedures to drain abscess (n=29), fluid collection after pancreatitis (n=3), lymphocyst after gynecological surgery (n=3), and the gallbladder transhepatically (n=1) between September 1997 and August 2003. The patient population was 28-86 years old and consisted of 19 men and 13 women. The drainage methods included a Seldinger's technique with a guidewire and serial dilators in every case. The procedures were guided by using a helical computed tomography scanner that provided real-time fluoroscopy reconstruction. RESULTS: Percutaneous drainage under real-time computed tomography-fluoroscopy guidance was successfully performed in every procedure. Real-time computed tomography-fluoroscopy allowed rapid assessment of needle, guidewire, dilator, and catheter placement. The only drainage-induced complication encountered was a subcutaneous hematoma after one procedure (2.8%). No patients had serious complications. The average procedure time was 32 minutes. CONCLUSIONS: Computed tomography-fluoroscopy is a useful method for guiding the accurate and safe drainage of abnormal thoracic, abdominal, and pelvic fluid collections.
