VIDEO: Preoperative CT Angiography for Scapula Osteocutaneous Free Flap Reconstructions.

ABSTRACT

OBJECTIVE. The objective of this video article is to discuss the use of the scapular osteocutaneous free flap in reconstructive procedures. We attempt to discuss normal and variant vascular anatomy, image acquisition via CT angiography, and image interpretation as well as computer-assisted design and manufacturing. CONCLUSION. The scapular osteocutaneous free flap is commonly used for maxillary and mandibular reconstructive surgery. The complex vasculature supplying the scapular region allows flap versatility. There are anatomic variations in the origin of the circumflex scapular and angular arteries. Our method of performing and reporting CT angiography for patients scheduled to undergo scapular osteocutaneous free flap procedures provides a reliable and reproducible means of communicating important elements of vasculature to surgeons. This in turn can facilitate the manufacturing of custom scapular cutting guides and improve surgical outcomes.
