Life threatening acute complication after routine catheter exchange-The importance of planning and preparedness in risk cases.
Article in Radiology 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
Endovascular procedures after abdominal surgery may carry risks for serious complications. Radical nephrectomy is preferred for renal cell carcinomas but carries risks including hemorrhage (1.2%), abscesses (0.7%-6.1%). Percutaneous abdominal drainage procedures carry hemorrhagic risks in 1%-2% of cases. An 88-year-old male with recent left sided nephrectomy developed a retroperitoneal abscess requiring drainage. During routine catheter upsizing, massive hemorrhage occurred due to injury of the left renal artery stump by the larger catheter. Emergency endovascular intervention was performed. Initial aortic stent graft placement alone proved insufficient due to anatomical constraints. Complete hemostasis was achieved through adding coil embolization of the arterial stump, while the partial stent coverage prevented coil migration. This case emphasizes that routine interventional procedures can precipitate life-threatening complications even in experienced hands.
