ABSTRACT

SUMMARY: In an investigation of 92 female and 79 male cadavers persistent sciatic and axial arteries were identified and classified based on their origin and location. Sciatic arteries were observed to arise from a number of different arteries in 68 specimens: anterior trunk of the internal iliac artery (12 specimen); internal pudendal artery (1 specimen); posterior trunk of the internal iliac artery (44 specimens); anterior and posterior trunks as a double artery (4 specimens); superior gluteal artery (7 specimens). In addition, the sciatic arteries were observed to give the superior and inferior gluteal arteries (12 and 9 specimens respectively). It is of note that a persistent sciatic artery was observed to give the superior or inferior gluteal artery rather than the superior or inferior gluteal artery giving the persistent sciatic artery: a persistent sciatic artery was also observed to exist with the superior or inferior gluteal artery. This questions the general embryological origin of a persistent sciatic artery. The embryological origin of the proximal part of the axial artery and whether it forms the superior or inferior gluteal artery is discussed, together with the general arrangement of the internal iliac and femoral arterial systems. Presentation of the sciatic artery is also discussed with respect to existing embryological theories and from a new perspective. A number of embryological vascular anomalies are also discussed.


RESUMEN: En este studio se identificaron y clasificaron las arterias ciáticas y axiales persistentes según su origen y ubicación en 92 cadáveres femeninos y 79 masculinos, Se observó que las arterias ciáticas surgían de varias arterias diferentes en 68 especímenes: tronco anterior de la arteria ilíaca interna (12 especímenes); arteria pudenda interna (1 espécimen); tronco posterior de la arteria ilíaca interna (44 especímenes); troncos anterior y posterior como una arteria doble (4 especímenes); arteria glútea superior (7 especímenes). Además, se observó que las arterias ciáticas daban las arterias glúteas superior e inferior (12 y 9 especímenes respectivamente). Cabe señalar que se observó que una arteria ciática persistente daba lugar a la arteria glútea superior o inferior en lugar de que la arteria glútea superior o inferior diera lugar a la arteria ciática persistente: también se observó que existía una arteria ciática persistente con la arteria glútea superior o inferior. Esto cuestiona el origen embriológico general de una arteria ciática persistente. Se discute el origen embriológico de la parte proximal de la arteria axial y si forma la arteria glútea superior o inferior, junto con la disposición general de los sistemas arteriales ilíaco interno y femoral. También se observó desde una nueva perspectiva la presentación de la arteria ciática con respecto a las teorías embriológicas existentes. Además se discuten varias anomalías vasculares embriológicas.

ABSTRACT

SUMMARY: The inferior epigastric artery (IEA) is a major blood vessel that supplies the anterior abdominal wall. The aim of the current study was to provide clinicians, surgeons, and obstetricians with sufficient anatomical data on the inferior epigastric artery, such as its origin and branching pattern. The study included 20 embalmed cadavers, these cadavers were dissected, and the inferior epigastric artery and vena comitans/venae comitantes were identified and traced downwards to the external iliac vessels. The origins, caliber, course and pedicle length of both the artery and the vein(s) were studied. The inferior epigastric artery arose independently from the distal external iliac artery deep to the inguinal ligament in 19 (95 %) cadavers. The artery entered the rectus abdominis muscle at its middle third in 13 (65 %) cases and at its lower third in the remaining specimens. In this study, we found that the artery divided into two branches in 18 (90 %) of the cases; in the remaining two cases, it continued as one trunk. The average pedicle length was 7.2 cm. The mean caliber of the IEA was 3.7 mm. In 18 (90 %) dissections, the venous drainage consisted of a pair of venae comitantes that united to form a common vessel at their draining point on the external iliac vein. The average diameter was 3.9 mm. The current study focuses on the anatomical features of the inferior epigastric artery to increase the success rate of abdominal and pelvic operations in clinical practice.


RESUMEN: La arteria epigástrica inferior (AEI) es un vaso sanguíneo principal que irriga la pared abdominal anterior. El objetivo del presente estudio fue proporcionar a los médicos, cirujanos y obstetras suficientes datos anatómicos sobre la arteria epigástrica inferior, como su origen y patrón de ramificación. El estudio incluyó 20 cadáveres embalsamados, los que se disecaron y se identificó la arteria epigástrica inferior y la vena concomitante y se siguieron hasta los vasos ilíacos externos. Se estudiaron los orígenes, calibre, trayecto y longitud del pedículo tanto de la arteria como de la (s) vena (s). La arteria epigástrica inferior surgió independientemente de la arteria ilíaca externa profunda al ligamento inguinal en 19 (95 %) cadáveres. La arteria ingresó al músculo recto del abdomen en su tercio medio en 13 (65 %) casos y en su tercio inferior en las muestras restantes. En este estudio, encontramos que la arteria se dividió en dos ramas en 18 (90 %) de los casos; en los dos casos restantes, continuó como un tronco. La longitud media del pedículo fue de 7,2 cm. El calibre medio del AEI fue de 3,7 mm. En 18 (90 %) disecciones, el drenaje venoso consistió en un par de venas concomitantes las que formaron un vaso común en su punto de drenaje en la vena ilíaca externa. El diámetro medio fue de 3,9 mm. El estudio actual se centra en las características anatómicas de la arteria epigástrica inferior con el propósito de mejorar la tasa de éxito de las cirugías abdominales y pélvicas en la práctica clínica.

ABSTRACT

Current study describes possible alterations of the terminal branches of dogs' abdominal aorta to determine their origin and compare them with other species. Thirty specimens of dogs (race not defined), 20 females and 10 males, varying in age and size, were used. The corpses were retrieved from previous practical classes at the veterinary anatomy laboratory of the Universidade de Sorocaba (UNISO), Sorocaba, Brazil. The dogs' femoral artery was dissected and catheterized by 10% formaldehyde injection and submerged for at least 48 hours in formalin-fixed vats for fixation. All animals were submitted to abdominal cavity access through the abdominal and lateral abdominal wall and later removed from the abdominal viscera to visualize the abdominal aorta and its terminal branches. Most of the animals under analysis presented, right and left external iliac artery, right and left internal iliac artery and a median sacral arteryas terminal branches of the abdominal aorta, whereas 9 dissected specimens showed a common trunk with internal iliac artery and medial sacral artery. Results show that there are variations among mammals with regard to the origins of terminal branches of the abdominal aorta.


Esse estudo teve o objetivo de descrever as possíveis alterações dos ramos terminais da aorta abdominal dos cães determinando a sua origem e comparando com as demais espécies. Foram utilizados 30 exemplares de cães SRD com idade e portes variados, sendo destes 20 fêmeas e 10 machos, todos os cadáveres provenientes de aulas práticas anteriormente ministradas no laboratório de anatomia veterinária da universidade de Sorocaba-UNISO. Os cadáveres tiveram sua artéria femoral dissecada em seguida cateterizada para injeção de formaldeído a 10% e posteriormente foram mantidos submersos por no mínimo 48 horas em cubas com formol para fixação. Todos os animais foram submetidos ao acesso da cavidade abdominal através da retirada da parede abdominal ventral e lateral e posteriormente retirada das vísceras abdominais para visualização da aorta abdominal e seus ramos terminais. A maioria dos animais estudados apresentou como ramos terminais da aorta abdominal, artéria ilíaca externa direita e esquerda, artéria ilíaca interna direita e esquerda e uma artéria sacral mediana, enquanto 9 espécimes dissecados apresentaram um tronco comum onde surgiu a artéria ilíaca interna e artéria sacral mediana, concluindo-se que existem variações das origens dos ramos terminais da aorta abdominal entre os mamíferos.

ABSTRACT

During the routine dissection, a rare anomaly was observed in left lower limb of a female cadaver. The external iliac artery continued as femoral artery, branched on lateral side as the lateral circumflex femoral artery and on medial side as profunda femoris artery. On tracing the lateral circumflex femoral artery, the ascending branch towards the spinous anastomosis was very thin and coursed behind the rectus femoris muscle. The transverse and descending branches were not observed, however, the artery coursed along the vastus lateralis towards the knee. The femoral artery had its normal course and continued as popliteal artery. The profunda femoris artery originated from the medial side of the external iliac artery, initially superficial to the femoral vein, coursed downwards and posteriorly, relating posteromedial to femoral artery. The medial circumflex femoral artery originated as thin branch, which further divided into two divisions. The profunda femoris gave origin of 3 perforators and continued as 4th perforator. The unusual branching pattern was observed to be novel and not reported in the literature.


Durante una disección de rutina, se observó una rara anomalía en el miembro inferior izquierdo de un cadáver de sexo femenino. La arteria ilíaca externa dio origen en el lado lateral ala arteria circunfleja femoral lateral y en el lado medial a la arteria femoral profunda. En el recorrido de la arteria circunfleja femoral lateral, la rama ascendente era muy delgada y corría detrás del músculo recto femoral. No se observaron ramas transversales y descendente, sin embargo, la arteria descendió hacia la rodilla a lo largo del músculo vasto lateral. La arteria femoral tuvo su curso normal y continuó como arteria poplítea. La arteria femoral profunda, inicialmente superficial a la vena femoral, se dirigió inferior y posteriormente colocándose posteromedial a la arteria femoral. La arteria circunfleja femoral medial se originó como una rama delgada, que otorgó dos arterias. La arteria femoral profunda dio origen a tres ramas perforantes y continuó como cuarta perforante. Este patrón de ramificación inusual es una descripción nueva no reportada en la literatura.

ABSTRACT

Variations of the external iliac artery are very rare. We found a rare variation in the left external iliac artery. The artery was long and formed a characteristic loop. The loop was found in the lesser pelvis in close relation to the obturator nerve. This loop may compress obturator nerve and vessels. The knowledge of this loop might be important for gynaecologists, orthopaedic surgeons and urologists since it may be involved in surgeries of hip, ovary and prostate...


Las variaciones de la arteria ilíaca externa son raras. Se encontró una variación poco frecuente en la arteria ilíaca externa izquierda. La arteria era larga y formaba un bucle característico. El bucle se encontró en la pelvis menor en estrecha relación con el nervio obturador. Este circuito puede comprimir el nervio obturador y los vasos circundantes. El conocimiento de este circuito podría ser importante para los ginecólogos, cirujanos ortopédicos y urólogos, ya que pueden estar involucrados en las cirugías de cadera, ovario y próstata...

ABSTRACT

An abnormal artery arising from external iliac artery was found during routine dissection class for medical undergraduates. The artery took its origin from the external iliac artery midway between its origin from common iliac and termination as femoral artery. The abnormal artery divided into two branches; an ascending and a descending. The ascending branch supplied iliacus and iliac crest. The descending branch entered the femoral triangle by passing behind the femoral sheath. It supplied the muscles of femoral triangle and anastomosed with medial circumflex femoral artery. The knowledge of this variation may be of use for surgeons doing surgery of femoral hernia.


Una variación arterial proveniente de la arteria ilíaca externa fue encontrada durante una disección de rutina en Medicina de pregrado. La arteria se originaba de la arteria ilíaca externa a mitad de camino entre su origen desde la arteria ilíaca común y su terminación, la arteria femoral. La arteria se dividía en dos ramas: ascendente y descendente. La rama ascendente suministraba la irrigación al músculo ilíaco y a la cresta ilíaca. La rama descendente entraba en el trígono femoral pasando por detrás de la vaina femoral y daba la irrigación a los músculos del trígono femoral, anastomosándose con la arteria circunfleja femoral medial. El conocimiento de esta variación puede ser de utilidad para los cirujanos que realizan cirugía de hernia femoral.
