Ανατομικές Παραλλαγές των άνω (STA) και κάτω (ITA) θυρεοειδικών αρτηριών.

Anatomical variations of upper (STA) and inferriors (ITA) thyroid arteries

The thyroid gland is the largest and most vascular endocrine gland that surrounds the anterior and lateral folds of the pharynx, larynx, esophagus and trachea as a shield.
In addition to its important endocrine functions, it retains a basic metabolic rate and is susceptible to many human diseases, such as thyrotoxicosis, hypothyroidism, cretinism, malignant tumors, infertility, etc.
The main thyroid blood supply is derived from two pairs of left and right upper thyroid artery vessels (STA) derived from the external carotid artery and the left and right lower thyroid artery (ITA) derived from the subclavian map.
Changes in the pattern of thyroid artery distribution, especially the upper thyroid artery, assume primary knowledge for neck surgeons because of the vital and topographical relationship with the external laryngeal nerve on the one hand and the avoidance of involuntary injuries in patients with thyroid disease due to excessive and uncontrolled haemorrhage.
In addition, a seven-dimensional knowledge of these variants is extremely useful in carrying out procedures such as carotid artery angiography in throat anatomy and thyroid abnormalities.
Variations in the thyroid vasculature are often documented in classic anatomical surgical manuals. Several reports have also published earlier studies of the incidence of STA from common carotid at 5-45%.
Research has determined that STA was more common than the ITA lower thyroid artery, and that the position of the arteries may be affected by anthropological factors.
Researchers have realized that STA is a stable "pot" whereas ITA does not exist in many mammals. Contrary views argue that the absence of any thyroid artery that feeds the thyroid gland may be beneficial for the

surgeon who has many problems in blood loss during any thyroid gland surgery.
The purpose of this study is to detail the changes in the origin of the upper and lower thyroid arteries.
