“…During the embryonic development, there is the formation of four ventral splenic vessels, where after its maturation two central roots disappear, thus, remaining the first and fourth roots that originate the anastomoses of the celiac trunk and SMA. If there is a bifurcation between these arteries at a level different than normal, there may be displacement of some vessel from the celiac trunk to SMA 20 , generating the possibility of variations involving vessels of origin or destination of the celiac trunk and the SMA 6 .…”

Introduction: Superior mesenteric artery (SMA) usually arises from the abdominal aorta, just below the celiac trunk and it supplies the midgut-derived embryonic structures. Anatomical variations in this vessel contribute to problems in the formation and/or absorption of this part of the intestine and its absence has been recognized as the cause of congenital duodenojejunal atresia. Objective: To analyze SMA anatomical variations in humans and the possible associated clinical and surgical implications. Methods: This is a systematic review of papers indexed in PubMed, SciELO, Springerlink, Science Direct, Lilacs, and Latindex databases. The search was performed by two independent reviewers between September and December 2018. Original studies involving SMA variations in humans were included. SMA presence/absence, level, place of origin and its terminal branches were considered. Results: At the end of the search, 18 studies were selected, characterized as for the sample, method to evaluate the anatomical structure and main results. The most common type of variation was when SMA originated from the right hepatic artery (6.13%). Two studies (11.11%) evidenced the inferior mesenteric artery originating from the SMA, whereas other two (11.11%) found the SMA sharing the same origin of the celiac trunk. Conclusion: SMA variations are not uncommon findings and their reports evidenced through the scientific literature demonstrate a great role for the development of important clinical conditions, making knowledge about this subject relevant to surgeons and professionals working in this area.

“…Total n=22203 Tabla I. Distribución de las variantes de la arteria hepática común (AHC) según casos reportados previamente en la literatura. (Fonseca et al, 2017;Gomes et al, 2014;Hiatt et al, 1994;Michels, 1966;Noussios et al, 2017;Ottone et al, 2012;Rodríguez y Fallas, 2011;Saiz et al, 2017;Skórzewska et al, 2014) En la actualidad, se ha identificado que cerca del 40% de los pacientes presenta variantes anatómicas en la circulación hepática (Doherty, 2014). Omitir la presencia de estas, ha generado un aumento en complicaciones quirúrgicas tales como: aumento en el riesgo de lesión vascular intraoperatoria (que cause sangrado, isquemia o necrosis), disfunción hepática postoperatoria (con elevación de enzimas hepáticas), ligadura accidental de variantes anatómicas, fístulas anastomóticas e inclusive fugas biliares anastomóticas.…”

Introducción: Las variantes de la arteria hepática común han sido estudiadas y descritas desde la antigüedad, con la subsecuente aparición de clasificaciones anatómicas para su correcta identificación. Se ha descrito que hasta un 40% de la población presentan dichas variantes. Metodología: Se realizó una revisión sistemática de la literatura utilizando los descriptores “arteria hepática”, “variación anatómica” y “anatomía” donde se obtuvo un registro de 22203 que habían sido reportados por diferentes investigadores anteriormente y se analizaron en conjunto. Resultados: La variantes anatómicas de la AHC fueron estudiadas y clasificadas por Michels, Lippert y Pabst, y Hiatt. Según la clasificación de Hiatt, 80,46% de los individuos se agrupan dentro del grupo I, 6,46% dentro del grupo II, 6,10% en el grupo III, 1,50% en el grupo IV, 1,32% en el grupo V y 0,02% en el grupo VI. El grupo X de Michels, no contemplado en la clasificación de Hiatt, representó el 0,04% de la muestra. Conclusiones: Se recomienda realizar estudios de imagen preoperatorios cuando se considere apropiado puesto que podría incidir en la disminución de complicaciones quirúrgicas y postquirúrgicas y se debería considerar realizar estudios descriptivos para determinar la incidencia de variantes anatómicas en la población local. Introduction: Variants of the common hepatic artery have been studied and described since ancient times, with the subsequent appearance of anatomical classifications for their correct identification. It has been reported that up to 40% of the population present these variants. Methodology: A systematic review of the literature was carried out by using the key words “hepatic artery”, “anatomic variation” and “anatomy”, resulting in a registry of 2203 individuals previously reported by various researchers which was analyzed as a whole. Results: Anatomical variants were studied and described by Michels, Lippert & Pabst, and Hiatt. According to the Hiatt classification, 80,46% of individuals were sorted in group I, 6,46% in group II, 6,10% in group III, 1,50% in group IV, 1,32% in group V and 0,02% in group VI. Michels’ group X, not included in Hiatt’s classification, represented 0,04% of the sample. Conclusions: Preoperative imaging studies are recommended when appropriate since it could result in a decrease in surgical and post-surgical complication. Descriptive studies that determine the incidence of anatomical variants in the local population should be considered.
