Una variación anatómica: la desembocadura aberrante del conducto torácico

Abstract: En uno de los cadáveres disecados durante el primer semestre de 2006 en el anfiteatro del Departamento de Morfología de la Universidad del Valle en Cali (Colombia), se encontró una variación anatómica poco descrita en la literatura científica mundial. Se trata de la desembocadura aberrante del conducto torácico. Normalmente, este conducto linfático asciende en el tórax y se desvía hacia el lado izquierdo del cuello para desembocar en el confluente venoso yúgulo-subclavio izquierdo. En este cadáver masculino de… Show more

“…The thoracic duct may present some anatomic variations: a. Not crossing to the left side of the body at the T4 level, therefore having its final segment on the level IV on the right side rather than on the left side, which happens in less than 25% of the cases 1,16,17 ; b. Duplicating or triplicating at the level of the thoracic vertebrae, thus being present bilaterally 1,[18][19][20][21]23 ; c. Draining into places other than the confluence between the left internal jugular vein and the left subclavian vein, the most frequent drainage area.…”

“…Duplicating or triplicating at the level of the thoracic vertebrae, thus being present bilaterally 1,[18][19][20][21]23 ; c. Draining into places other than the confluence between the left internal jugular vein and the left subclavian vein, the most frequent drainage area. It has been reported that the thoracic duct may drain into the left subclavian vein 10,17,18,20,21 ; the left internal jugular vein 1,10,17,21,22 ; the brachycephalic vein 1,17,21 ; the left vertebral vein 1,21 ; right venous system 1,[16][17][18]20,21 ; azygous vein 21 ; transverse cervical vein 17 or the inferior vena cava 19,21 . The chyle fistula is a severe neck dissection complication and that the best treatment is its prevention.…”

“…In the lymphatic system, the thoracic duct is the main and largest vessel component, with approximately 3 mm caliber and approximate length between 38 and 45 cm from the upper abdomen to the base of the neck, where it opens into one of the large veins there present. It rises in the level of the second lumbar vertebra, on the right, and subsequently in relation to the abdominal aorta medially to the right pillar of the diaphragm from a dilatation called chyle cistern, which is formed by the junction of the lumbar and intestinal trunks (PEÑA and ZUNIGA, 2009); (GARDNER, GRAY and O'RAHILLY, 2008). Ascends in the posterior mediastinum, to the right of the aorta, between the aorta and vena ázigos (GARDNER, GRAY and O'RAHILLY, 2008); (MOORE, 2001); (GRAY, 2010).…”

“…In the base of the neck, makes a loop and crosses the subclavian artery. After that it goes forward and descends, ending in the left jugular vein 2 , or other large vein in the region (PEÑA and ZUNIGA, 2009) (Figure 1).…”
