Background The vascular anatomy of the supraclavicular artery island (SAI) flap has been investigated using both cadaveric anatomic dissections and angiographic studies. Accurate preoperative evaluation localization its pedicle confirms location, course, variation, improves success. objective this report is to demonstrate utility multislice computed tomography (CT) angiography for confirming presence SAI when planning head neck reconstruction. Methods Patients were studied 64-multislice CT (CTA) localize artery, including origin destination. Axial images, multiplanar reconstructions, 3D volume-rendered images analyzed on a Philips workstation. Radiologic image findings clinical experience will be described. Results was successfully performed in 15 patients (30 shoulders) ranging from ages 22 81 years. identification main achieved 14/15 patients. Location, length, variations reported 23 30 arteries. Mean vessel diameter found 1.49 mm (range, 0.8–2.0 mm) right 1.51 1.0–2.1 left. mean length 38.3 26.6–59.6 38.4 left 24.3–67.0 mm). In all patients, originated off transverse cervical artery—a branch thyrocervical trunk. Positioning patient’s upper extremities at side helpful distribution. Contrast injection site should contralateral needed if sidedness importance, secondary contrast bolus artifact. Conclusions Preoperative with feasible A radiologic study protocol developed which ability detect vessel. This technique provides noninvasive approach easily standardized/reproducible. can benefit surgical team during design flap; however, these optimize outcome.
