Study of anatomical variations of the superficial palmar arch of fetuses in Córdoba, Argentina

The blood supply to the hand depends on the superficial palmar arch (SPA) and the deep palmar arch (DPA), both formed by the radial artery (RA) and ulnar artery (CA). According to the description in anatomy textbooks, the superficial palmar arch is formed by the anastomosis between the superficial p...

description The blood supply to the hand depends on the superficial palmar arch (SPA) and the deep palmar arch (DPA), both formed by the radial artery (RA) and ulnar artery (CA). According to the description in anatomy textbooks, the superficial palmar arch is formed by the anastomosis between the superficial palmar branch of the radial artery (SPB) and the cubital artery. This is the “normal” version of the SPA. However, during the performed dissections, various types of SPA conformations were observed, different from the “normal or classic” model. When performing the bibliographic search, it was confirmed that there are various anatomical variations described in international literature, which led to deepening this research with a greater number of dissected pieces. Since this study began a few weeks ago, it was not possible to obtain a larger sample to include in this presentation. The objective of this work is to record which are the variations of the constitution of the superficial palmar arch resulting from native fetal anatomical dissections, in this environment, Córdoba, and to serve as a guide for professionals involved in the diagnosis and treatment of the hand region. Ten palmar regions were dissected corresponding to five fetuses weighing less than 500 grams, from 16 to 24 weeks, 3 female and 2 male. Microdissection instruments and binocular magnifying glasses were used. The variations found were: 1 - anastomosis between the ulnar artery and the superficial palmar branch of the radial artery (40%); 2 - ulnar artery as the only structure, without the existence of a superficial palmar arch (40%); 3 - ulnar artery and superficial palmar artery, without forming SPA, nor anastomosing with each other (20%). Based on these results, it is observed that the “normal or classic” type (40%) of the description in anatomical study books or atlases is less frequent than the sum of the atypical variations found together (60%). Knowing the possible anatomical variations of the superficial palmar arch becomes important in surgical procedures performed on the hand.

La irrigación sanguínea de la mano depende del arco palmar superficial (APS) y del arco palmar profundo (APP), ambos formados por la arteria radial (AR) y arteria cubital (AC). Según la descripción de los libros de texto de anatomía el arco palmar superficial se forma por la anastomosis entre la rama palmar superficial de la arteria radial (RPS) y la AC. Esta es la versión “normal” del APS. Sin embargo, durante las disecciones realizadas se observaron diferentes tipos de conformación del APS, diferentes al modelo “normal o clásico”. Al realizar la búsqueda bibliográfica se constata que existen diversas variedades anatómicas descriptas en la literatura internacional, lo cual llevó a profundizar esta investigación con mayor cantidad de piezas disecadas. Dado que este estudio comenzó hace pocas semanas no se logró alcanzar una muestra mayor para incluir en esta presentación. El objetivo de este trabajo es registrar cuales son las variedades de la constitución del arco palmar superficial resultantes de las disecciones anatómicas fetales autóctonos, en este medio, Córdoba, y que sirva como guía para los profesionales que intervienen en el diagnóstico y tratamiento de la región de la mano. Se disecaron 10 regiones palmares correspondientes a 5 fetos menores a 500 gramos, de 16 a 24 semanas, 3 femeninos y 2 masculinos. Se utilizó instrumental de microdisección y lupas binoculares. Las variedades encontradas fueron: 1 - anastomosis entre arteria cubital y rama palmar superficial de la arteria radial (40%); 2 - arteria cubital como única estructura, sin existencia de arco palmar superficial (40%); 3 - arteria cubital y la arteria palmar superficial, sin formar ACS, ni anastomosarse entre sí (20%). Basándose en estos resultados, se observa que el tipo “normal o clásico” (40%) de la descripción de los libros de estudio o atlas anatómicos es menos frecuente que la suma de las variedades atípicas halladas en conjunto (60%). Conocer las posibles variedades anatómicas del arco palmar superficial adquiere importancia en los procedimientos quirúrgicos que se realicen en la mano.  Universidad Nacional Córdoba.
