Summary
Real-time computed tomography-fluoroscopy (CT-F) guided percutaneous drainage effectively and safely manages thoracic, abdominal, and pelvic fluid collections. This imaging guidance ensures accurate catheter placement with minimal complications.
Area of Science:
- Interventional Radiology
- Medical Imaging
- Surgical Procedures
Background:
- Percutaneous drainage is essential for managing abnormal fluid collections.
- Real-time imaging guidance is crucial for procedural accuracy and safety.
Purpose of the Study:
- To evaluate the efficacy of real-time computed tomography-fluoroscopy (CT-F) guidance for percutaneous drainage.
- To assess the safety and accuracy of CT-F guided drainage of thoracic, abdominal, and pelvic fluid collections.
Main Methods:
- 32 patients underwent 36 CT-F guided percutaneous drainage procedures.
- Procedures targeted abscesses, pancreatitis fluid collections, lymphocysts, and gallbladder drainage.
- Seldinger's technique with serial dilators was employed under helical CT with real-time fluoroscopy.
Main Results:
- Successful percutaneous drainage was achieved in all 36 procedures.
- CT-F enabled rapid assessment of instrument placement.
- A single minor complication (subcutaneous hematoma) occurred (2.8%); no serious complications were reported.
Conclusions:
- Real-time CT-F guidance is a valuable tool for percutaneous drainage.
- The method facilitates accurate and safe management of thoracic, abdominal, and pelvic fluid collections.
