Transverse Cervical Artery

The transverse cervical artery arises from the subclavian in about 61% of cases and from the thyrocervical trunk in about 38%.

When it arises from the subclavian, it is usually behind or lateral to scalenus anterior.

When it is absent, it is compensated for by branches from the dorsal scapular, superficial cervical, costocervical trunk, or the distal or third part of the subclavian or even the axillary artery.

If the artery arises medial to scalenus anterior it is, without exception, a branch of the thyrocervical trunk. It may arise from the dorsal scapular (possibly as high as 20%). In addition, it sometimes arises from the inferior thyroid, internal thoracic, costocervical trunk, or the first part of the subclavian.

According to Röhlich the transverse cervical artery arose in common with the suprascapular artery from the thyrocervical trunk. Right side, 41 cases (45.5%); Left side, 33 cases (39.2%); total, 74 cases (42.6%); in Men, 49 cases (44.5%); in Women, 25 cases (39%).

The transverse cervical arose from the inferior thyroid, which arose from a common stem with the suprascapular and the internal thoracic arteries. Right side, 2 cases (2.2%); Left side, 6 cases (7.1%); total, 8 cases (4.5%); in Men, 4 cases (3.6%); in Women, 4 cases (6.2%).

The transverse cervical arose from the thyrocervical trunk. Right side, 41 cases (45.5%); Left side, 36 cases (42.8%); total 77 cases (44.2%); in Men, 44 cases (41.8%); in Women 31 cases (48.4%).

The transverse cervical arose from the inferior thyroid, which arose from a common stem with the ascending cervical and suprascapular arteries. Right side, 3 cases (3.3%); Left side, 5 cases (5.9%); total, 8 cases (4.5%); in Men, 6 cases (4.5%); in Women, 2 cases (3.1%).

The transverse cervical arose from the thyrocervical trunk from which the ascending cervical and internal thoracic arteries arose from a common stem. Left side , 1 case (1.1%); total 1 case (0.5%); in Men, left side, 1 case (1.9%); total 1 case, (0.9%).

The transverse cervical artery was absent. Right side, 4 cases (4.4%); Left side, 5 cases (5.9%); total 9 cases (5.1%); in Men, 7 cases (6.3%); in Women, 2 cases (3.1%)
