Percutaneous abscess drainage is a safe and effective procedure; however, the techniques used can vary considerably between facilities owing to a lack of standardization. In this report, we aimed to describe the imaging modalities, devices, and techniques implemented in our department to provide useful information on how to perform percutaneous abscess drainage successfully and safely. Our technique of percutaneous abscess drainage includes ultrasound (US)- or computed tomography (CT)-guided abscess puncture, switching to fluoroscopy guidance, contrast medium injection into the abscess cavity, hydrophobic guidewire (GW) insertion, and the advancement of a drainage catheter and metal stiffening cannula without the use of a dilator.
