Analysis of 5 cases of PICC removal difficulty caused by fibroblastic sleeve.

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
objectiveTo explore the difficulties and solutions encountered during the removal of PICC catheters in five patients with a fibroblastic sleeve formation.
methodsThis study includes five cases of PICC (peripherally inserted central catheter) removal difficulty caused by the formation of a fibroblastic sleeve. The patients were selected from a cohort with two cases involving the basilic vein in the right elbow fossa, two cases involving the brachial vein in the right elbow fossa, and one case involving the right cephalic vein. All patients underwent ultrasonography to exclude phlebitis and thrombosis.
resultsThe fibroblastic sleeve was identified as wrapping around the catheter's tip, leading to significant resistance during removal. The treatment approach involved thrombolysis, specifically using urokinase slowly injected into the catheter, combined with the application of a tourniquet. This method successfully facilitated catheter removal.
conclusionFor patients with fibroblastic sleeve formation or catheter adhesion to the vessel wall, applying a tourniquet 11-15 cm above the puncture site may assist in successful PICC removal.
