A Case of Pediatric Supracondylar Humerus Fracture Requiring Vascular Reconstruction for Brachial Artery Injury: The Importance of Rapid Vascular Assessment.

Supracondylar humeral fractures are the most commonly observed pediatric fractures in clinical practice. Associated brachial artery injuries are rare complications; however, published case reports documenting the need for vascular reconstruction are limited. An eight-year-old boy presented with pain in the left elbow after he fell. Radiograph revealed a severely displaced supracondylar humeral fracture. Initially, the radial pulse was absent; nonetheless, the fingers remained perfused. However, the rapid onset of digital pallor required urgent open reduction and vascular reconstruction. Bone union was achieved within seven weeks postoperatively, with restoration of symmetrical radial pulses. In this case, the risk of rapid vascular deterioration in pediatric supracondylar humeral fractures was emphasized. Frequent vascular assessments are essential, as vigilant monitoring and prompt intervention can mitigate complications, prevent long-term sequelae, and ensure better patient outcomes.
