Acute right brachial artery embolism after left upper division segmentectomy with suspected pulmonary vein stump thrombus.

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
Systemic arterial embolism is an uncommon but potentially serious complication after lung resection. A 63-year-old woman underwent thoracoscopic left upper division segmentectomy for lung adenocarcinoma. On postoperative day (POD) 2, she developed sudden pain, numbness, and weakness of the right upper limb. Bedside ultrasonography showed right brachial artery occlusion, and contrast-enhanced computed tomography (CT) confirmed a distal brachial artery filling defect. A small filling defect was also observed at the pulmonary vein stump, but the embolic source could not be established. Emergency thrombectomy using a Fogarty catheter restored arterial perfusion ~4 h after symptom onset, followed by anticoagulation. Contrast-enhanced CT on POD 28 showed resolution of the pulmonary vein stump filling defect, and no recurrent embolism or bleeding occurred during 3 months of follow-up. This case highlights that sudden upper-limb symptoms after left upper division segmentectomy should prompt immediate vascular assessment, timely revascularization, and evaluation of possible embolic mechanisms.
