Undescribed Breast Blood Supply from the Brachial Artery: Circumflex Mammary Artery.
Article in Cardiovascular and interventional radiology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
purposeRecent advancements in medical technologies have made trans-arterial treatment of breast cancer feasible. Consequently, understanding the vascular anatomies of breast cancers and axillary lymph node metastases has become indispensable for sophisticated treatments. The aim of this study was to determine the vascular anatomy of the breast, which is crucial for trans-arterial chemoembolization in patients with breast cancer. MATERIALS AND
methodsA total of 126 treatment-naive breast cancer patients were investigated to evaluate the arteries supplying breast tissues, tumours, and axillary lymph node metastases. The breast-supplying arteries were identified via angio-CT scans performed in the same examination room.
resultsAs described in anatomical textbooks, the main arteries supplying breast tissues and tumours are mammary branches arising from the internal thoracic artery and lateral thoracic artery. However, an undescribed serpiginous artery arising from the brachial artery distal to the subscapular artery and circumflex humeral artery was discovered in 46.0% of patients. This artery partially supplied breast tumours in 30.2% of the patients. The circumflex mammary artery is presumed to be a normal variant that is not pathologically enlarged due to tumour angiogenesis. Axillary lymph node metastases are supplied mainly by the lateral thoracic artery and thoracodorsal artery.
conclusionWe identified an undescribed serpiginous artery arising from the brachial artery distal to the subscapular artery or circumflex humeral artery, and we named this the circumflex mammary artery.
