Recurrent Ischemic Strokes in a Young Breast Cancer Patient Due to Interatrial Septal Perforation by a Chemotherapy Port Catheter.

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
Totally implantable venous access ports (PACs) are widely used in oncology and are generally considered safe. However, rare mechanical complications may lead to severe consequences. We report the case of a 27-year-old woman undergoing chemotherapy for breast cancer who developed recurrent ischemic strokes likely due to interatrial septal perforation by a PAC catheter. Transthoracic echocardiography revealed migration of the catheter into the left atrium, creating a direct pathway for systemic embolization. Early recognition and catheter removal prevented further events, and no recurrent ischemic events were observed during the three months of follow-up. This case highlights the importance of assessing catheter malposition when new neurological symptoms arise after PAC placement.
