Preoperative simulation results and intraoperative image fusion guidance for transjugular intrahepatic portosystemic shunt placement: a feasibility study of nineteen patients.

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
purposeThe purpose is to evaluate the feasibility and efficacy of preoperative simulation results and intraoperative image fusion guidance during transjugular intrahepatic portosystemic shunt (TIPS) creation.
methodsNineteen patients were enrolled in the present study. The three-dimensional (3D) structures of the bone, liver, portal vein, inferior vena cava, and hepatic vein in the contrast-enhanced computed tomography (CT) scanning area were reconstructed in the Mimics software. The virtual Rosch-Uchida liver access set and the VIATORR stent model were established in the 3D Max software. The puncture path from the hepatic vein to the portal vein and the release position of the stent were simulated in the Mimics and 3D Max software, respectively. The simulation results were exported to Photoshop software, and the 3D reconstructed top of the liver diaphragm was used as the registration point to fuse with the liver diaphragmatic surface of the intraoperative fluoroscopy image. The selected portal vein system fusion image was overlaid on the reference display screen to provide image guidance during the operation. As a control, the last 19 consecutive cases of portal vein puncture under the guidance of conventional fluoroscopy were analyzed retrospectively, including the number of puncture attempts, puncture time, total procedure time, total fluoroscopy time, and total exposure dose (dose area product).
resultsThe average time of preoperative simulation was about 61.26 ± 6.98 minutes. The average time of intraoperative image fusion was 6.05 ± 1.13 minutes. The median number of puncture attempts was not significantly different between the study group (n = 3) and the control group (n = 3;
conclusionThe use of preoperative simulation results and intraoperative image fusion to guide a portal vein puncture is feasible, safe, and effective when creating a TIPS. The method is cheap and may improve portal vein puncture, which may be valuable for hospitals lacking intravascular ultrasound and digital subtraction angiography (DSA) equipment equipped with a CT-angiography function.
