Summary

The posterior interosseous artery is a viable source for arterial grafts used in thumb and finger reconstruction. Harvesting this vessel does not cause functional deficits, making it ideal for revascularization and nerve transfers.

Background:

Autogenous arterial grafts are crucial for revascularizing digits in cases of trauma or vascular compromise.
The posterior interosseous artery has been explored as a potential donor site for these grafts.

Observation:

The posterior interosseous artery, ranging from 1 to 1.5 mm in caliber, can be harvested in lengths of 8 to 10 cm from the dorsal ulnar forearm.
This artery can be harvested with a concomitant lateral branch of the posterior interosseous nerve, enabling vascularized nerve transfer.
Careful dissection is required to avoid injury to the motor branches of the posterior interosseous nerve.

Findings:

Successful harvesting of the posterior interosseous artery for arterial grafting was demonstrated.

The procedure did not result in peripheral perfusion deficits or functional impairment in the donor limb.

The harvested graft was successfully utilized in a clinical case, as reported.

Implications:

This technique offers a reliable method for obtaining arterial grafts for digital revascularization and replantation.
The ability to perform simultaneous vascularized nerve transfer enhances reconstructive options.
The safety and efficacy of using the posterior interosseous artery as a donor site are supported by this case report.
