RESUMO

There is an infrequent disposition of the first metacarpal artery which results in an anastomosis with the common palmar digital artery of the second space, forming an anastomotic system between the deep radial system and the superficial ulnar system. The radial system in turn, through the first dorsal interosseous artery, anastomoses with a collateral of the common palmar digital artery of the second space, ending as the ulnar palmar digital artery of the thumb and establishing a second anastomotic system. A third anastomosis is established in one case, between the common palmar digital artery of the fourth space and the fourth metacarpal artery. To this may be added the classic anastomosis between the superficial branch of the ulnar artery and the deep branch of the radial artery, i.e. the deep palmar arch.

RESUMO

El arco palmar superficial (APS) resulta de la unión de la arteria ulnar y la rama palmar superficial de la arteria radial. Por su convexidad nacen las arterias digitales comunes. Esta descripción es la única que distintos autores han tomado como válida, por lo que se espera encontrarla durante la disección con mayor frecuencia. Esto no ha sido verificado en nuestra experiencia. Nos proponemos llevar a cabo una revisión de la descripción del APS poniéndolo en contraposición con las disecciones realizadas. Se disecaron y analizaron 61 manos cadavéricas. Estudio del arco palmar superficial: Variante clásica del APS: 23 casos (37,7 %). Variante no clásica del APS: 15 casos (24,6 %). Tipo A: 13 casos (86,7 %). Anastomosis entre arterias ulnar y metacarpiana dorsal del primer espacio. Tipo B: 2 casos (13,3 %). Anastomosis entre arterias ulnar y satélite del nervio mediano. Ausencia del arco: 23 casos (37,7 %) Tipo A: 19 casos (82,6 %). La arteria ulnar es la única estructura en el plano del APS. Tipo B: 3 casos (13 %). La arteria ulnar y la rama palmar superficial de la arteria radial están en el plano del APS sin anastomosarse entre sí. Tipo C: 1 caso (4,4 %). La arteria ulnar y la satélite del nervio mediano están en el plano del APS sin anastomosarse. Estudio de la quinta arteria digital palmar común: La quinta arteria digital palmar común se originó de las distintas variantes en 41 casos (67,2 %). Recomendamos al momento de la disección considerar que: la variante clásica no es la más frecuente de hallar; la ausencia del arco se verifica en el mismo porcentaje que la variante clásica; incluso cuando se comprueba la presencia del APS, el porcentaje de la variante no clásica es contundente; la quinta arteria digital palmar común es una rama colateral constante del APS.


The superficial palmar arch (SPA) is formed by the union of the ulnar artery and the superficial palmar branch of the radial artery. From its convexity four branches emerge, known as the common palmar digital arteries. We propose to carry out a review of the description of the SPA in contrast to the dissections carried out. Sixty-one hands were dissected and studied. Analysis of the SPA: Classic variant of the SPA: 23 cases (37.7 %). Nonclassic variant of the SPA: 15 cases (24.6 %). Type A: 13 cases (86.7 %). Anastomosis between the ulnar artery and the first dorsal metacarpal artery. Type B: 2 cases (13.3 %). Anastomosis between the ulnar artery and the satellite artery of the median nerve. Absence of the arch: 23 cases (37.7 %) Type A: 19 cases (82.6 %). The ulnar artery is the only one present in the plane of the SPA. Type B: 3 cases (13 %). The ulnar artery and the superficial palmar branch of the radial artery are in the plane of the superficial palmar arch, there is no anastomosis between them. Type C: 1 case (4.4 %). The ulnar artery and the satellite artery for the median nerve are in the plane of the SPA, there is no anastomosis between them. Analysis of the fifth common palmar digital artery: The fifth common palmar digital artery originates from the different variants in 41 cases (67.2 %). Based on the results, we recommend at the time of dissecting consider that: The classic variant is not the most frequent to find. The absence of the arch is verified in the same percentage rate as the classic variant. Even when the SPA is present, the percentage rate of the non-classic variant is significant. The fifth common palmar digital artery is a constant collateral branch of the superficial palmar arch.

RESUMO

A persistent median artery is a rare anomaly. It accompanies the median nerve along its course in the forearm and is of variable origin. It is associated with other local anatomical variations and may contribute significantly towards formation of the superficial palmar arch. In embryos, it is responsible mainly for the blood supply to the hand. The objective of this study was to research the frequency, type (forearm or palmar) and origin of the median artery in fetuses, correlating its presence with sex and body side. Red-colored latex was injected into 32 brachial arteries of human fetuses until its arrival in the hand could be seen. Twenty-four hours after the injection, the median arteries were dissected without the aid of optical instruments. Among the 32 forearms dissected, the median artery was present in 81.25 % (26) of the cases, and it was found more frequently in females and on the left side. Regarding origin, most of the median arteries originated in the common interosseous artery (38.5 %) and anterior interosseous artery (34.6 %). The mean length of the median arteries was 21.1 mm for the palmar type and 19.8 mm for the forearm type. The median artery has a high rate of persistence. It is important to be aware of this anatomical variation, since its presence may give rise to difficulties during routine surgical procedures on the wrist. Its presence may cause serious functional complications in the carpal tunnel, anterior interosseous nerve, round pronator syndromes, and ischemia of the hand.

RESUMO

La irrigación de la palma de la mano es proporcionada por arcos arteriales (superficial y profundo) que están conformados más frecuentemente por las arterias ulnar y radial estableciendo un patrón descrita como clásico. Se describen variaciones anatómicas en la conformación de ambos arcos, más frecuentemente en el arco palmar superficial; pudiendo ser los mismos completos o incompletos. Es objetivode este trabajo, la descripción anatómica de los arcos palmares, de sus diferentes patrones y variaciones de conformación, y sus implicancias clínico-quirúrgicas. Se llevó a cabo un estudio descriptivo, observacional y morfométrico de las arterias que participan en la formación de los arcos palmares; se utilizaron 100 preparaciones cadavéricas fijadas en solución de formol, de la Tercera Cátedra de Anatomía - Facultad de Medicina- Universidad de Buenos Aires. Se realizó además un análisis retrospectivo de casos con lesiones de la/sarteria/s principal/es que conforman los arcos palmares, en el Servicio de Emergencias del Hospital de Morón, entre 2015-2016. La arteria radial conforma el arco arterial profundo con la arteria cubito palmar más frecuentemente en el 100 % de los casos. El arco arterial superficial es el más variable. Fue completo en el 56 % y la presentación más frecuente (83 %) es aquella que se conforma por la anastomosis de la arteria ulnar y la arteria radiopalmar. El resto de las anastomosis son: entre arteria ulnar y arteria mediana (9 %),entre rama profunda de arteria radial y arteria ulnar (5 %); triple anastomosis entre arteria ulnar, arteria mediana y arteria radiopalmar (2 %), y anastomosis entre la arteria mediana y la arteria radiopalmar, sinparticipación de la arteria ulnar (1 %). El resto de la muestra (44 %) se lo puede denominar como incompleto. Los subtipos B1a y B1b fueron los más encontrados. Se describen dos casos clínicos, uno con sección completa de la arteria radial a nivel de la muñeca y el otro con sección completa de arteria ulnar con compromiso del nervio ulnar. Resulta esencial un correcto conocimiento de los arcos palmares para un adecuado abordaje quirúrgico de la mano. La importancia de la presencia o ausencia, así como de las distintas variaciones de los arcos arteriales palmares radica en su aplicación clínica quirúrgica como punto departida en el tratamiento del trauma como de otras patologías en las que existe compromiso de estos vasos.


The irrigation of the palm is provided by arterial arches (shallow and deep) that are made more frequently by the ulnar or radial arteries described as setting a classic pattern. Anatomical variations are described in shaping both arches, most often in the superficial palmar arch; may be the same complete or incomplete. The objective of this work is the anatomical description of the palmar arches, their different patterns and variations in conformation, and their clinical and surgical implications. A descriptive, observational and morphometric study of the arteries involved in the formation of the palmar arches was done in the Faculty of Medicine, University of Buenos Aires. One hundred 1(00) cadaveric preparations fixed in formalin solution, of the Third Chair of Anatomy were used. A retrospective analysis of cases with lesions / s artery /main / s that make the palmar arches in the Emergency Hospital of Moron, between 2015-2016 s was alsocarried out. Most frequently the radial artery forms the deep palmar arch with the deep palmar branch ofthe ulnar artery. Superficial palmar arch is the most variable. It was complete in 56 % and the most common presentation (83 %) is one that is formed by the anastomosis of the ulnar artery and the superficial palmar branch of the radial artery. The rest of the anastomosis are between ulnar artery and median artery(9%), between deep branch of radial artery and ulnar artery (5 %); triple anastomosis between ulnar artery,median artery and superficial palmar branch of the radial artery (2 %), and anastomosis between the median artery and superficial palmar branch of the radial artery without participation of the ulnar artery (1%). The rest of the sample (44 %) can be termed as incomplete. The B1a and B1b subtypes were the mostfound. Two cases, one entire section of the radial artery at the wrist and the other with complete section ofulnar artery with involvement of the ulnar nerve are described. It is essential to a proper understanding ofthe palmar arches for a suitable surgical approach to hand. The importance of the presence or absence, aswell as different variations of palmar arterial arch lies in its clinical application as surgical starting point in the treatment of trauma and other diseases in which there is engagement of arteries.

RESUMO

Introducción: La irrigación palmar ha sido investigada en diferentes grupos poblacionales mediante la disección anatómica directa. Sin embargo, no existe una clasificación estandarizada de arcos palmares superficiales, lo cual conduce a que diferentes autores diseñen clasificaciones propias. Objetivo: Determinar los diferentes patrones del arco palmar superficial y la relevancia tanto clínica como quirúrgica de las diversas variantes anatómicas asociadas a esta estructura. Metodología de búsqueda: Se realizó una búsqueda de literatura en las bases de datos Medline, Ovid, Proquest, Cochrane, SciELO, Lilacs y Hinary, además de textos clásicos de anatomía y cirugía. Se seleccionaron estudios retrospectivos y transversales en especímenes cadavéricos realizados en diferentes grupos poblacionales entre 1987 hasta 2014. Resultados: Se utilizó la clasificación de arco palmar superficial establecida por Lippert y Pabst, que presentó el arco palmar superficial completo como el patrón vascular más común, con una prevalencia del 56,7%, en la que el subtipo más frecuente fue el radio-ulnar clásico con un 64%. La prevalencia del arco palmar superficial incompleto fue de 48,8%, con un subtipo de patrón ulnar reportado en el 24,7% de las muestras evaluadas. Conclusiones: El adecuado conocimiento de los diferentes patrones de la irrigación palmar es esencial para realizar abordajes exitosos en cirugías de mano y para la comprensión de la fisiopatología de enfermedades de carácter laboral como el síndrome de martillo hipotenar.

Introduction: The palmar irrigation has been the subject of research in different population groups using direct anatomical dissection. However, there is no standardized classification of superficial palmar arches, which leads the different authors to design own classifications. Objective: to determine the different patterns of superficial palmar arch, and the clinical and surgical revelance of the various anatomical variants associated with this structure. Research methodology: A literature search was performed in data bases Medline, Ovid, Proquest, Cochrane, Scielo, Lilacs and Hinary, besides classical texts of anatomy and surgery. Retrospective and cross-sectional studies were selected in cadaveric specimens made in different population groups between 1987 to 2014. Results: It was used the superficial palmar arch classification established by Lippert and Pabst, that presented the complete superficial palmar arch as the most common vascular pattern, with a prevalence of 56.7%, in which was the most common subtype the classic radio-ulnar (64%). The prevalence of incomplete surperficial palmar arch was 48.8%, with a subtype of ulnar pattern reported in 24.7% of the samples tested. Conclusions: Adequate knowledge of the different patterns of palmar Irrigation is essential for successful approaches in hand surgery, and for understanding the pathophysiology of diseases related to employment as hypothenar hammer syndrome.

RESUMO

The classic description of the hand's superficial palmar arch is based on the anastomosis among the ulnar and radiopalmar arteries, a branch of the radial artery. However, the arch formation is highly variable regarding the size of the arteries that make it up and due to the existence of branches coming from other arteries and adding up as tributary to it. The objective of this paper is to classify these possible varieties, to define the formation of the arch, the reasons for its variable arrangement and the importance of its clinical and surgical applications. 86 formalized hands were dissected at 40 percent. There is prevalence concerning the size of the ulnar artery, with or without an arch. The anatomic knowledge of the variability in the arch formation becomes important in the application of surgical techniques that can help treating pathologies of the hand.


La descripción clásica del arco palmar superficial de la mano se basa en la anastomosis entre las arterias ulnar y radiopalmar, rama de la arteria radial. Igualmente, la formacion del arco es altamente variable desde el punto de vista del tamaño de las arterias que lo conforman y a la existencia de ramas provenientes de otras arterias y que se suman a las anteriores como tributarias del arco. El objetivo de este trabajo fue clasificar estas posibles variaciones, para definir la formacion del arco, las razones de su composicion variable y la importancia de sus aplicaciones clínicas y quirúrgicas. Fueron disecadas 86 manos, formolizadas al 40 por ciento. Existía prevalencia de la arteria ulnar respecto a su tamaño, con o sin la formación de arco. El conocimiento anatómico de la variabilidad de la formación del arco palmar superficial es de fundamental importancia en la aplicación de técnicas quirúrgicas que pueden ayudar en el tratamiento de diversas patologías de la mano.
