| description |
The thoracic duct (TD) is the largest infradiaphragmatic collector of lymphatic vessels in the body. It forms from mesodermal endothelial cells during the sixth week of gestation. In the different stages of its development, differentiated atrophies of the ducts can be observed. In the adult individual, there is a wide variability in the anatomical arrangement of the origin, path and drainage into the venous system of the duct in question. Given that in the international bibliography the studies published on the subject are limited, especially regarding fetal specimens, this research is proposed for the purpose of determining the anatomical varieties of the thoracic duct in fetuses.
Twenty-four fetuses were dissected, 14 male and 10 female, from 13 to 24 weeks of gestation, from the Misericordia and Provincial Maternity Hospital of the city of Córdoba. The mediastinum and retroperitoneum regions were dissected in order to find and expose the TD. The results obtained are tabulated in a table.
The TD was found in 21 of the 24 fetuses (87.5%), with 15 cases (63%) of TD with a path similar to the one described in the bibliography (variety a), among which, 9 had the cisterna chyli with a saccular appearance, except for one case in which it was possible to describe it as a "pearl necklace", i.e. a succession of dilations. The TD venous drainages were right in 12.5% and left in 87.5% of the fetuses. In the rest of the specimens, varieties were found and classified as: (b) TD of right drainage (12.5%), (c) absence of TD (12.5%), (d) TD of left origin and drainage (4.17%), (e) TD of anterior path to the esophagus (4.17%) and (f) TD of an anterior path to the aorta in a curved shape (4.17%).
Due to the clinical and surgical implications of injuries in the TD, knowledge of its diverse anatomical varieties is important in order to avoid diagnostic or therapeutic errors. |

El conducto torácico (CT) es el colector más voluminoso de los vasos linfáticos infra-diafragmáticos del cuerpo. Su desarrollo embrionario comienza a partir de células endoteliales mesodérmicas durante la sexta semana de gestación. En los diferentes estadíos de maduración son observables atrofias diferenciadas de los conductos. En el individuo adulto, existe una amplia variabilidad en la disposición anatómica del nacimiento, trayecto y desembocadura en el sistema venoso del conducto en cuestión. Dado que en la bibliografía internacional los estudios publicados sobre el tema son escasos y aún más respecto a especímenes fetales, se propone la realización de esta investigación, con el objetivo general de determinar las variedades anatómicas del conducto torácico en fetos. Se disecaron 24 fetos, 14 masculinos y 10 femeninos, de 13 a 24 semanas de gestación, provenientes del Hospital Misericordia y Maternidad Provincial de la ciudad de Córdoba. Se disecaron las regiones del mediastino y retroperitoneo para así hallar y exponer el CT. Los resultados obtenidos se tabulan en una tabla registro. La presencia del CT fue hallada en 21 de los 24 fetos (87,5%). Se encontraron 15 casos (63%) de CT de trayecto identificable con el descrito en la bibliografía (variedad a), dentro de los cuales, en 9 se identificó la cisterna del quilo de aspecto sacular, a excepción de un caso en el cual fue posible describirla como un “collar de perlas”, una sucesión de dilataciones. Las desembocaduras venosas del CT fueron derechas en el 12,5% e izquierdas en el 87,5%. En el remanente se encontraron variedades que fueron clasificadas como: (b) CT de desembocadura derecha (12,5 %), (c) ausencia del CT (12,5%), (d) CT de nacimiento y desembocadura izquierda (4,17%), (e) CT de trayecto anterior al esófago (4,17%) y (f) CT de trayecto anterior a la aorta en forma curva (4,17%). Debido a las implicancias clínicas y quirúrgicas de lesiones en el CT, se destaca la importancia del conocimiento de las diversas variedades anatómicas del mismo para así evitar errores diagnósticos o terapéuticos.
