RESUMO

Two angiographic instances of anomalous external carotid artery (ECA) and internal carotid artery (ICA) anastomosis are described, each occurring at the C2-3 level and bearing remnants of proximal ICA. The ICA remnant of one patient (identifiable immediately upon bifurcation of the common carotid artery) was hypoplastic, and that of the other patient was an occluded arterial stump. These features are not typical of non-bifurcating ICA. The occipital artery originated from an anomalous connection in one instance and from the main trunk of the ECA (just past the ECA-ICA connection) in the other.

RESUMO

The variations in the origin of the facial and lingual arteries are very important in maxillofacial, head and neck surgery procedures. This study is a case report in which the common origin is described in the facial and lingual artery in a lingual-facial trunk (LFT) on the left side of a female corpse from Spain. In the examination, a diameter of 2.17 mm and a length of 8.84 mm are shown. It was located 12.04 mm from the carotid bifurcation and 9.31 mm from the origin of the superior thyroid artery. The variation in biometric values shown, are anatomical findings in the neck dissection of a corpse. Moreover, taking into account the surgical procedures, which involve the origin of facial and lingual artery, because it is the most common variation and could cause complications.


Las variaciones del origen de la arteria facial y lingual son importantes en los procedimientos de cirugía maxilofacial y de cabeza y cuello. Reportamos un caso en el que se describe el origen común de las arterias facial y lingual en un tronco linguofacial en el lado izquierdo en el cadáver de una mujer de origen español. En la examinación, el tronco presentó un diámetro de 2,17 mm y una longitud de 8,84 mm. Se ubicó a 12,04 mm de la bifurcación carotidea y a 9,31 mm del origen de la arteria tiroidea superior. La variación en los valores biométricos presentados constituyen un hallazgo anatómico en una disección de cuello de un cadáver, además ser tomada en cuenta en los procedimientos quirúrgicos que involucren el origen de la arteria facial y lingual, pues al ser la variación más común podría generar complicaciones.

RESUMO

Variations of vessels and nerves in the left neck side, of 65 year old male cadaver, during the routine dissections, were detected. It was observed that the linguofacial trunk originated from external carotid artery and that the ascending pharyngeal artery originated from the occipital artery. It was determined that after the laryngeopharyngeales rami originated from the superior cervical ganglion, the branch wound around the origin of the superior thyroid artery. As an additional variation, the internal jugular vein divided. The cervical ansa and the inferior belly of the omohyoid muscle passed through the parts of the vein. We think that these type of variation can entail important difficulties during radiologic and surgical procedures of the neck region. To know these anatomical variations, is important for the anatomist and surgeons.


Durante una disección de rutina, fue observada en el lado izquierdo del cuello de un cadáver de sexo masculino de 65 años de edad variaciones anatómicas vasculares y nerviosas. Se observó que el tronco linguofacial se originaba de la arteria carótida externa y que la arteria faríngea ascendente se origina en la arteria occipital. Se determinó que los ramos laringofaríngeos originadas desde el ganglio cervical superior, giraban en torno al origen de la arteria tiroidea superior. Como una variación adicional, la vena jugular interna se encontró dividida. El asa cervical y el vientre inferior del músculo omohioideo pasaban a través de las partes de la división de la vena. Creemos que este tipo de variaciones supone dificultades importantes durante procedimientos radiológicos y quirúrgicos de la región del cuello, y por tanto, es importante que los cirujanos conozcan estas variaciones.
