Postoperative rupture of bronchial stump inducing severe hemorrhage from pulmonary artery trunk: a case report.
Article in Journal of cardiothoracic surgery, 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
Surgical resection constitutes the cornerstone of treatment for lung cancer, a disease with high global incidence. Among postoperative complications, delayed fatal hemorrhage occurring beyond 30 days postoperatively has garnered scant attention in clinical and research settings. Notably, there are no documented cases of vascular rupture and bleeding induced by chronic mechanical friction between the bronchial stump and pulmonary artery trunk to date. Following pulmonary lobectomy, the anatomical proximity between the bronchial stump and pulmonary artery trunk creates a potential risk of delayed pulmonary artery hemorrhage secondary to bronchial stump-related pathology. Herein, we report a case of a 53-year-old male patient who presented with sudden massive hemoptysis on the 40th day after right upper lobectomy. Bronchial artery embolization was initially performed but failed to control the bleeding. Emergency thoracotomy revealed a 3-mm rupture with active bleeding in the right pulmonary artery trunk, accompanied by a 2-mm fistula at the right upper lobe bronchial stump. Intraoperatively, the vascular rupture was repaired using a pericardial patch, and both the repaired vessel and the bronchial stump were wrapped with an intercostal muscle flap, achieving successful hemostasis. The patient experienced an uneventful postoperative recovery and remained alive and well at the 3-month follow-up. Written informed consent was obtained from the patient for the publication of this case report and the accompanying clinical images.
