The superior thyroid artery shows a great variability in what concerns its origin. Most often, it appears as an independent branch of the external carotid artery, as its first collateral branch, or directly from the common carotid or at its terminal level. The superior thyroid artery origin was evaluated on 144 cases, using as study methods the dissection (39 cases), the plastic injection (22 cases) and the CT angiography evaluation (83 cases). It was studied, by percentage, the originating artery of the superior thyroid artery, the relation to the bifurcation of the common carotid artery, the neighboring arterial branches and the surface of the external carotid on which originated, the caliber of the external carotid artery before and after the origin of the superior thyroid artery. Most commonly, in 89 cases (61.80%), we describe the origin of the superior thyroid artery from the external carotid artery; from the common carotid artery originated 31 superior thyroid arteries (21.53%); at the level of the bifurcation of the common carotid artery, the superior thyroid artery had its origin in 21 cases (14.58%); in 2 cases (1.39%) we encountered the superior thyroid artery originating from a thyro-lingual trunk and in one case (0.69%), we met a thyro-linguo-facial trunk. The superior thyroid arteries may originate as an independent artery or as arterial trunks in varying proportions. When the origin of the superior thyroid artery is from the terminal common carotid, we propose to use the expression of terminal branching or the common carotid artery trifurcation. The results of our study are similar to those found in international literature, with statistical differences that may be attributed primarily to the total number of cases on which we worked and also working methods or may be attributed to other causes, such as the geographic area where the study was conducted and the amount of time the results were obtained.

Abstract the methods of dissection and analysis of angioCT’s. Each of the details was analyzed comparatively on both sides of the body assessing: the origin of the superior thyroid artery in relation to the carotid bifurcation, the face of the external carotid artery that gives origin and the traject of the artery from the origin to the glandular parenchyma. The origin of the superior thyroid artery was evaluated on a number of 64 cases, most frequently having its origin from the external carotid artery, an aspect met 53.125 % of cases, at a distance that was between 1-18 mm. In 28.125 % of cases the superior thyroid artery had its origin in the common carotid trunk at a distance of 1-10 mm caudal to the terminal bifurcation of the common carotid. In 18.75 % of cases, the thyroid artery originated from the carotid bifurcation, which thus ends up by trifurcation. The side of the vessel that emerges the superior thyroid artery was assessed on 42 cases; most commonly the superior thyroid artery having its origin on the medial face, an aspect found in 66.67 % of cases; in 23.81 % of cases originated from the posterior medial and only two cases (4.76 % of cases), both on the left side(8.70 % of cases on the left), the origin of the superior thyroid artery was located on the anterior, respectively faces of the common carotid artery. The traject of the superior thyroid artery was followed on 53 cases, in most cases the artery showing initially a horizontal traject (transverse) towards medially for 1-4 cm, then became obliquely downward, an aspect met in 28.30 % of cases and in 22.64 % of cases, the artery was obliquely downward from its origin. In 11.32 % of cases the traject was obliquely ascending and in 9.43 % of cases the artery was initially obliquely upward for 2-3 cm, after which became transverse. For the remaining 28.30 % of the cases we have met a number of other 5 different patterns of traject but in a small percentage for each of them (5.66% of cases).

Abstract Background The major arterial supply to the thyroid gland is from the superior and inferior thyroid arteries, arising from the external carotid artery and the thyrocervical trunk respectively. The external laryngeal nerve runs in close proximity to the origin of the superior thyroid artery in relation to the thyroid gland. The superior thyroid artery is clinically important in head and neck surgeries. Objectives To locate the origin of the superior thyroid artery, because wide variability is reported. To provide knowledge of possible variations in its origin, because it is important for surgical procedures in the neck. Methods The origin of the superior thyroid artery was studied by dissecting sixty adult human hemineck specimens from donated cadavers in a Department of Anatomy. Results The highest incidence observed was origin of the superior thyroid artery from the external carotid artery (88.33%), whereas origin from the common carotid bifurcation only occurred in 8.33%. However, in 3.33% of cases, the superior thyroid artery originated from the common carotid artery and in a single case, the external laryngeal nerve did not cross the stem of the superior thyroid artery at all, but ran ventral and parallel to the artery. Conclusions It is important to rule out anomalous origin of superior thyroid artery and verify its relationship to the external laryngeal nerve prior to ligation of the artery in thyroid surgeries, in order to prevent iatrogenic injuries. Moreover, because anomalous origins of the superior thyroid artery are only anatomic variants, thorough knowledge of these is decisive for head and neck surgeries.

AbstractDevelopmental anomalies in the origin and branching pattern of the external carotid artery are not common. The level of the bifurcation of the common carotid artery and also the variations in the origin/branching pattern of the external carotid artery are well known and documented. During a routine dissection of middle aged male cadaver in department of Anatomy in BP Koirala Institute of Health Sciences (BPKIHS) The clinically-relevant variations to be noted were the high origin and anomalous course of the facial artery, superior thyroid artery arising as a branch of Common Carotid artery, high origin of ascending pharyngeal artery, posterior auricular artery and direct glandular branches to the Submandibular gland. Such anatomical variations of external carotid artery are important for surgeons in surgeries of head and neck region and also for radiologists in the image interpretation of the face and neck region.

Unusual Origin

Thyroid surgeries are most common neck surgeries; hence thorough knowledge of the variations in blood supply of this gland to the surgeons is very important to prevent any alarming hemorrhage or iatrogenic damage. We found a variation in origin of superior thyroid artery on right side during routine dissection on an adult male cadaver in the Department of Anatomy, A.I.I.M.S, NewDelhi. Left superior thyroid artery was normal. Right side, superior thyroid artery was arising from common carotid artery instead of external carotid artery, just proximal to the bifurcation of common carotid artery. This variant branching pattern of superior thyroid artery is very rare. The inferior thyroid arteries did not show any unusual origin. Knowledge of such arterial variations related to the thyroid gland is immensely helpful to the surgeons to avoid damage of the vital organs in this region.

Las anomalías en el origen y patrón de ramificación de la arteria carótida externa (ACE) son comunes. El nivel de la bifurcación de la arteria carótida común (ACC) y las variaciones en el origen / patrón de ramificación de la arteria carótida externa están bien documentados. En el hallazgo de las arterias occipitales y posteriores surgían de un corto tronco común de la ACE en el lado izquierdo. El conocimiento de las variaciones en el origen y curso de las ramas de la ACE  son de suma importancia en la cirugía. Los cirujanos deben ser conscientes de la posibilidad de encontrar estas variaciones, ya que pueden conducir a dificultades en la distinción de las ramas de la arteria carótida externa. Este conocimiento es también importante para los radiólogos en la interpretación de las imágenes de las regiones de la cara y el cuello.  Anomalies in the origin and branching pattern of the external carotid artery (ECA) are common. The level of the bifurcation of the common carotid artery (CCA) and the variations in the origin/branching pattern of the external carotid artery are well documented. In the present finding occipital and posterior auricular arteries were arising by a short common trunk from ECA on the left side. Knowledge of variations in the origin and course of branches of ECA is of importance in surgery. Surgeons need to be aware of the possibility of encountering such variations, as they may lead to difficulties in differentiating the branches of external carotid artery. This knowledge is also important for radiologists in the image interpretation of the face and neck regions.

Abstract OBJECTIVE We designed a new external shunt system and evaluated its indications and efficacy in patients undergoing carotid endarterectomy (CEA). METHODS In 8 of 332 CEA procedures, external shunts were placed between the common carotid artery and the internal carotid artery (ICA). This procedure was implemented for one of two indications: 1) a change in electroencephalographic and/or somatosensory evoked potential readings immediately after ICA occlusion, or 2) elongation of the ICA made safe insertion of an internal shunt impossible. In addition, a shunt was placed between the common carotid artery and the external carotid artery to establish collateral circulation from the external carotid artery to the intracranial circulation, which is essential during ICA occlusion. RESULTS All external shunts were functional, and electroencephalography and somatosensory evoked potentials demonstrated no significant abnormalities during the CEAs. All patients awoke from surgery without manifestation of new neurological deficits. CONCLUSION Our new external shunt device proved safe and efficacious in cases that did not permit the placement of an internal shunt.

Background: Arterial myointimal hyperplasia (MIH) has a significant impact on the long-term outcomes of vascular procedures such as bypass surgery and angioplasty. In this study, we describe a new and innovative technique to induce MIH using a dental flossing cachet in Wistar rats. Methods: The intimal damage in the common carotid artery was induced by inserting the tip of the dental flossing cachet through the external carotid artery into the common carotid artery and turning it on for 3 rounds of 20 s each (n = 10). After 2 weeks, the rats were anesthetized and the common carotid arteries of the experimental side and the contralateral side (control) were harvested and preserved for histopathological studies. Results: The experimental carotid arteries showed significant intimal proliferation and thickening compared to the controls. The intima/media ratio of the experimental and normal (control) common carotid arteries were 1.274 ± 0.162 and 0.089 ± 0.023 (mean ± SEM), respectively (p < 0.001). Conclusion: This technique is simple, inexpensive, and highly reproducible and it induces sufficient MIH to study this phenomenon in animal models.

ABSTRACTCommon carotid artery (CCA) usually does not have any branches in the neck and divides into internal and external carotid artery. Superior thyroid and lingual artery (commonly called as thyro lingual trunk) are the branches of external carotid artery. We report a case of rare origin of thyrolingual trunk from the CCA in a case of ruptured intracranial aneurysm.
