Supraclavicular nerve entrapment by the external jugular vein: An unreported finding.

OBJECTIVE

We aim to describe the supraclavicular nerve's vascular entrapment by the external jugular vein as an unreported anatomical finding.

CASE DESCRIPTION: In a routine cadaveric dissection, the superficial emergence of the first division of the left supraclavicular nerve emerged along a duct formed through the external jugular vein. No other vascular or neural anatomical abnormalities were found in the surrounding structures.

CONCLUSION

This unreported vascular entrapment of the supraclavicular nerve by the external jugular may harbour clinical implications for surgical and endovascular procedures on the external jugular vein and in refractory thoracic and scapular waist pain.
