Real-time Fluoroscopic Fusion Imaging Guidance Using Angio-computed Tomography for Percutaneous Drainage of a Difficult-to-access Liver Abscess: A Case Report.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
A liver abscess developed in the left subphrenic space in a 42-year-old man with liver metastases from gastric cancer. Because ultrasound did not detect the abscess, percutaneous drainage was planned with real-time fluoroscopic fusion imaging guidance using angio-computed tomography. A computed tomography scan was obtained, and the abscess cavity was manually delineated using dedicated software. On the basis of pre- and intra-procedural computed tomography images, the transhepatic epigastric approach was selected. The delineated area was overlaid onto fluoroscopy, and a needle was advanced toward the overlaid target. A drainage catheter was inserted using the Seldinger technique. No adverse events occurred, and the inflammatory markers improved after drainage. This case reveals the potential utility of real-time fluoroscopic fusion imaging guidance using angio-computed tomography for abscess drainage in anatomically challenging locations.
