“…In essence, any kind of surgical intervention within the neck levels III and IV (Neck Dissection ClassiWcation, 2001) [15] can lead to unintentional injury of an anomalous VA, even during a biopsy on neck tissues. The VA injury during tracheotomy is rare but can occur in cases when the VA anomaly coexists with anomalies of other arteries of the region [16].…”

In order to examine 'ultrasound' approach in detecting the course of the vertebral artery (VA) and its anomalies important for neck surgery. An observational study with retrospective analysis of ultrasound images. 500 VAs on 250 3D CT angiographies and 500 ultrasound images performed on the same set of patients were analyzed. The relationship between the extraosseous portions of the VA to the neck organs with a special emphasis to the thyroid gland area, and the abnormal position of the VA were detected. Ultrasound and CT 3D images were compared. Ultrasound detected that 29 out of 500 VAs were anomalous (5.8%), 3D CT detected 30 cases. These anomalies were found in 22 patients (8.8%) (23 for 3D CT; 9.2%), in 7 (31.8%) of them bilaterally. An abnormal level of entrance (C3, C4, and C5) was observed in all anomalous cases. An additional case detected by 3D CT indicated C7 level of entrance. The ultrasound data correspond the CT data in 96.7% of cases. In ten cases (33.3%) the anomalous VA run close to the thyroid gland even touching the lower pole (16.7%; n = 5) or the upper pole (10.0%; n = 3) of the gland. In ten cases (33.3%) the anomalous VA crossed common carotid artery and the internal jugular vein by a way of a median loop. The incidence of anatomic variations of the VA is significant. Preoperative ultrasound investigation allows precise identification of anomalous VAs. Radiation-free ultrasound investigation of blood vessels is as precise as CT 3D imaging.

“…Whereas absence of both inferior thyroid an. is rare, [1,13,29,34,39], lack of three or even all of the regular arterial vessels is an isolated phenomenon [10,29]. From a practical point of view it must be stressed that the thyroid aa.…”

During routine dissection of an 89-year-old female donor both inferior thyroid aa. as well as the left superior thyroid a. were found to be absent, whereas the right superior thyroid a. came from the right common carotid. A large lowest thyroid a. rose from the left internal thoracic a. at the level of the first intercostal space. Up to this point the internal thoracic a. was of immense diameter, almost reaching that of the lateral part of the subclavian. The lowest thyroid a. ascended in an oblique and sigmoid course to the thyroid gland. Slightly left of the median line it bifurcated into two branches. Both had a winding course in front of the trachea before entering the base of the thyroid gland. Other arterial variations of minor significance were also observed in this unique case. The clinical impact lies in the localisation, course and size of the lowest thyroid a. reported.

“…This inconstant artery, usually detected on the right side, may be given off from the BT (0.5-3%) [18,43], the RCCA (0.5-1%) [41,43], the aortic arch (0.1-2.22%) [35,43], the internal thoracic artery, the pericardiophrenic artery, the subclavian artery, the thyrocervical trunk, the inferior thyroid artery or the transverse scapular artery. An IMA replacing the left inferior thyroid artery [42] or an IMA arising from the BT associated with bilateral absence of the inferior thyroid arteries were detected [73]. In both cases the right and left recurrent laryngeal nerves (RLNs) had a typical course.…”
