Case in brief
A 64-year-old woman presented with a right diaphyseal clavicle fracture and ipsilateral rib fractures following a cycling accident. During open reduction and internal fixation of the clavicle, an anomalous external jugular vein was discovered coursing anterior to the clavicle. The surgery proceeded without complications, highlighting the importance of preoperative imaging.
What made this case unusual
The presence of an anomalous external jugular vein anterior to the clavicle is a rare finding that can pose a risk of significant hemorrhage during surgical intervention.
Diagnostic / clinical pearl
Surgeons should be vigilant for anomalous vascular anatomy in the vicinity of clavicle fractures, as identified through preoperative imaging, to prevent intraoperative complications.
Why it matters
Recognizing and planning for anomalous vessels can enhance surgical safety and outcomes in clavicle fracture repairs.
