To describe the anatomy of the transverse cervical artery and to prove its perfusion to the clavicle using indocyanine green fluorescence angiography as an alternative vascularized bone for head and neck reconstruction.
Cadaveric dissection.
Anatomy lab.
Twenty-two necks and shoulders from 11 fresh-frozen cadavers were dissected. The transverse cervical artery diameter, length, emerging point, and the length of clavicle segment harvested were described. Photographic and near-infrared video recordings of the bone's medial and longitudinal cut surfaces were taken prior to, during, and after indocyanine green injection.
The transverse cervical artery originated from the thyrocervical trunk and emerged at the level of the medial one-third of the clavicle in 22 of 22 (100%) specimens. The average length of the pedicle was 3.6 cm (range, 2.2-4.4 cm), and the mean diameter was 2.5 mm (range, 1.8-3.4 mm). The harvested bone had a mean length of 5.1 cm (range, 4.3-5.8 cm). After injecting the indocyanine green, 22 of 22 (100%) specimens showed enhancement in the periosteum, bony cortex, and medulla.
The middle third of the clavicle can be reliably harvested as a vascularized bone with its perfusion solely from the transverse cervical artery pedicle, as shown by the near-infrared fluorescence imaging. The pedicle was sizable and constant in origin.
描述颈横动脉的解剖结构，并使用吲哚菁绿荧光血管造影术证明其对锁骨的灌注情况，以作为头颈部重建的一种替代带血管骨。
尸体解剖。
解剖实验室。
对11具新鲜冷冻尸体的22个颈部和肩部进行解剖。描述颈横动脉的直径、长度、发出点以及所获取锁骨段的长度。在注射吲哚菁绿之前、期间和之后，对骨骼的内侧和纵向切面进行摄影及近红外视频记录。
在22个（100%）标本中，颈横动脉均起自甲状颈干，并在锁骨中内1/3交界处发出。蒂的平均长度为3.6厘米（范围2.2 - 4.4厘米），平均直径为2.5毫米（范围1.8 - 3.4毫米）。所获取骨骼的平均长度为5.1厘米（范围4.3 - 5.8厘米）。注射吲哚菁绿后，22个（100%）标本的骨膜、骨皮质和骨髓均显示增强。
如近红外荧光成像所示，锁骨中1/3可作为一种仅由颈横动脉蒂供血的带血管骨可靠获取。该蒂大小合适且起源恒定。
