Variation of the Lateral Sacral Artery in relation to Sciatic Neuropathy

The lateral sacral artery usually originates from the posterior trunk of the internal iliac artery. The current study of 342 specimens from 171 cadavers (79 male, 92 female) investigated the origin and course of the lateral sacral artery. It was observed to arise from the posterior trunk in 79.1%. Occasionally it originated from the anterior trunk that occurred in 1%. It arose from the sciatic artery in 8.8%, from the superior gluteal artery in 16.8%, and from the inferior gluteal artery in 5.4%. Conversely, the lateral sacral artery is congenital absence in 0.3%. In addition, the lateral sacral artery was single, double, triple, and quadruple in 77.2%, 19.8%, 2.3%, and 0.3%, respectively. Consequently, variability of the lateral sacral artery origin is due to vascular demand as the lateral sacral artery plexus does arise from the earlier trunk development. With variability of the lateral sacral artery origin, there is a variability of the sciatic nerve supply. Knowing the variability of origins, surgeons have to avoid prolonged ligation of the internal iliac artery or its posterior trunk during surgical procedures which may lead to sciatic neuropathy. Therefore, the lateral sacral artery origin, course, and branches are important for clinicians to improve their knowledge and patient management.

En estudios anteriores de la arteria ilíaca interna se la ha clasificado en cinco tipos; sin embargo en base a una revisión de estos estudios parece que no hay una clasificación asociada en coexistencia con una arteria ciática. En este estudio, basado en la disección de 171 cadáveres (92 hombres y 79 mujeres), en 65 especímenes del tipo de la arteria ilíaca interna no podía ser clasificada debido a la presencia de una arteria ciática o ausencia de la arteria glútea inferior. Por lo tanto, se propone un sistema de clasificación modificado, ya que es esencial para los radiólogos, cirujanos ortopédicos, obstetras, ginecólogos y urólogos, para ser capaces de reconocer la organización de las principales ramas de las ramas ilíacas internas y evitar el trauma iatrogénico y las complicaciones postquirúrgicas, así como mejorar el manejo del paciente. In previous studies the internal iliac artery has been classified into five types; however based on a review of these studies it does not appear a classification associated with the coexistence of the sciatic artery. In this study, based on 171 dissected cadavers (92 male, 79 female), in 65 specimens the type of internal iliac artery could not be classified due to the presence of a sciatic artery or absence of the inferior gluteal artery. A modified classification system is therefore proposed as it is essential for radiologists, orthopedics, surgeons, obstetricians, gynecologists and urologists to be able to recognize the organization of the major branches of the internal iliac branches to avoid iatrogenic trauma and postsurgical complications, as well as to improve patient management.

Objetivo: Estudiar el patrón de ramificación de la arteria ilíaca interna del feto y que son equivalentes a la disposición de las ramas ilíacas internas en los adultos. Métodos: Veinticuatro mitades de pelvis fueron utilizados como muestras. Que se obtuvieron de fetos nacidos muertos, de 5 a 9 meses de edad gestacional. Resultados: la arteria ilíaca interna está en consonancia con la arteria ilíaca común y más grande que la arteria ilíaca externa. Tres tipos de ramificación se observaron sobre la base de las grandes ramas, a saber, la arteria glútea inferior, la arteria pudenda interna y la arteria glútea superior. Los resultados se correlacionaron con los patrones de ramificación descriptos por Piersol (1930). Conclusión: La disposición más común, tenía dos grandes troncos procedentes de la arteria iliaca interna, la posterior era la arteria glútea superior y la anterior se dividía en arterias pudenda y glútea inferior. Los otros patrones conducen variables en los adultos que son de importancia embriológicos y quirúrgicos. Objective: To study the branching pattern of fetal internal iliac artery and to correlate with the arrangement of the internal iliac branches in adults. Methods: Twenty four pelvic halves were used as specimens. They were obtained from the dead born fetuses of 5 to 9 months of gestational age. Results: Internal iliac artery was in line with the common iliac artery and larger than the external iliac artery. Three types of branching were observed based on the large branches namely inferior gluteal artery, internal pudendal artery and superior gluteal artery. The findings were correlated with the patterns of branching described by Piersol (1930). Conclusion: The most common arrangement had two large trunks originating from internal iliac artery, the posterior one being superior gluteal artery and the anterior one divided into internal pudendal and inferior gluteal arteries. The other patterns lead to variable branching patterns in adults that are of embryological and surgical significance.

Internal Iliac

AbstractMost commonly, the Obturator artery arises from the anterior trunk of internal iliac artery. However, origin of the Obturator artery from external iliac artery was reported at 25% by Missankov et al. [3], 1.1% by Bergman et al. [1], 1.3% by Jakubowicz and Czerniawska- Grzesinska [2].Due to its high frequency of variations in course and origin, Obturator artery had drawn the attention of anatomists, surgeons and radiologists. In this case report, we are presenting an anomalous origin of right Obturator artery from right external iliac artery. The knowledge of this variation is important anatomically, radiologically and surgically.
