Pinch-off syndrome-related port catheter migration requiring surgical extraction combined with coronary artery bypass grafting.
Article in Journal of surgical case reports, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Pinch-off syndrome is a rare but potentially serious complication of subclavian venous port systems, resulting from mechanical compression between the clavicle and first rib and leading to catheter fracture and embolization. A 63-year-old man with lung cancer presented with a fractured port catheter that had migrated into the left main and lower lobe pulmonary arteries. Endovascular retrieval was attempted but was unsuccessful due to firm endothelial adhesion. Preoperative coronary angiography revealed concomitant significant coronary artery disease. The patient subsequently underwent successful surgical catheter extraction combined with coronary artery bypass grafting. This case illustrates a Grade 3 pinch-off syndrome and highlights the limitations of percutaneous techniques in chronically embedded catheters. It also demonstrates that a combined surgical approach can be a safe and effective strategy in selected patients.
