Proximal interruption of the pulmonary artery with systemic bronchial/intercostal aneurysm formation: a case report.
Article in CVIR endovascular, 2025. 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
Proximal Interruption of the Pulmonary Artery (PIPA) is a rare congenital condition with an incidence of 1 in 200,000-300,000 individuals. We report the case of a 67-year-old woman with PIPA who presented with massive haemoptysis. Imaging revealed a small calibre right main pulmonary artery, absence of upper/middle lobe pulmonary arteries, and tortuous right systemic collateral arteries. A multidisciplinary meeting favoured bronchial artery embolisation over right pneumonectomy, due to the bleeding risk associated with extensive transpleural systemic collateral arteries. The patient underwent two staged bronchial artery embolisation and remained free of haemoptysis at the most recent 13-month follow-up. This case highlights the potential for bronchial artery embolisation to serve as a first-line treatment in managing PIPA, as a less invasive alternative to surgery.
