Delayed-Onset Postsurgical Myofascial Pain Following Axillary Artery Cannulation: A Case Report.
Article in Cureus, 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
Chronic postsurgical pain (CPSP) is often attributed to neuropathic, genetic, or psychosocial factors, whereas musculoskeletal causes, such as myofascial pain syndrome (MPS), are frequently overlooked. We report a case of delayed-onset MPS as a musculoskeletal manifestation of CPSP following axillary artery cannulation, aiming to raise awareness of this potential etiology. A 48-year-old man developed persistent right anterior chest pain one year after total arch replacement surgery. Physical examination revealed postural asymmetry, atrophy of the right pectoralis major muscle, mechanical allodynia, and myofascial trigger points (MTrPs) near the cannulation site and scapula. Ultrasonography demonstrated the disrupted architecture of the pectoralis major and adjacent connective tissue. Based on clinical and sonographic findings, MPS was diagnosed. Treatment included pregabalin, ultrasound-guided trigger point injections (TPIs) with levobupivacaine and triamcinolone, and type II pectoral nerve blocks. Five biweekly sessions led to significant pain relief, resolution of allodynia, and improved posture. This case highlights the importance of recognizing delayed-onset MPS as a musculoskeletal manifestation of CPSP following axillary artery cannulation, likely related to localized muscle trauma and pectoral nerve injury, and supports the value of multimodal management.
