ABSTRACT
The inferior epigastric artery usually arises from the external iliac artery. It may arise from different origin. The aim of current study is to provide sufficient date of the inferior epigastric artery for clinician, radiologists, surgeons, orthopaedic surgeon, obstetricians and gynaecologists. The current study includes 171 dissected cadavers (92 male and 79 female) to investigate the origin and branch of the inferior epigastric artery in United Kingdom population (Caucasian) as well as in male and female. The inferior epigastric artery found to be a direct branch arising independently from the external iliac artery in 83.6 %. Inferior epigastric artery arises from common trunk of external iliac artery with the obturator artery or aberrant obturator artery in 15.1 % or 1.3 %. Further, the inferior epigastric artery gives obturator and aberrant obturator branch in 3.3 % and 0.3 %. Therefore, the retropubic connection vascularity is 20 % which is more in female than male. As the retropubic region includes a high vascular variation, a great precaution has to be considered prior to surgery such as hernia repair, internal fixation of pubic fracture and skin flap transplantation. The radiologists have to report treating physicians to decrease intra-pelvic haemorrhage due to iatrogenic lacerating obturator or its accessory artery.
La arteria epigástrica inferior se origina generalmente de la arteria ilíaca externa, pudiendo presentar diferentes orígenes. El objetivo del presente estudio es proporcionar suficiente información de la arteria epigástrica inferior de su importancia para los clínicos, radiólogos, cirujanos, cirujanos ortopédicos, obstetras y ginecólogos. El estudio incluyó 171 cadáveres disecados (92 masculinos y 79 femeninos) pertenecientes a individuos caucásicos de Arabia Saudita con la finalidad de investigar el origen y las ramas de la arteria epigástrica inferior. La arteria epigástrica inferior fue hallada como rama directa independiente de la arteria ilíaca externa en un 83,6 %. La arteria epigástrica inferior se originaba de la arteria iliaca externa en un tronco común con la arteria obturatriz o arteria obturatriz accesoria en el 15,1 % y 1,3 %, respectivamente. La arteria epigástrica inferior daba una rama obturatriz y una obturatriz accesoria en el 3,3 % y 0,3 %, respectivamente. De esta manera, la vascularización retropúbica fue del 20 %, siendo mayor en mujeres que en hombres. Como la región retropúbica incluye una elevada variación vascular, esta arteria tiene que ser considerada antes del acto quirúrgico, como en los casos de la cirugía de hernia, la fijación interna en fracturas del pubis y el trasplante de colgajo de piel. Los radiólogos tienen que informar a los médicos tratantes de estas variaciones para contribuir en la disminución de la hemorragia intra-pélvica debido a la lesión iatrogénica de la arteria obturatriz o su arteria accesoria.

<p><b>OBJECTIVE</b>To evaluate the efficacy and advantages of personalized 3D printing-guided template of lateral superior ramous of pubic intramedullary lag screw.</p><p><b>METHODS</b>From July 2015 to December 2016, 20 patients with the superior and inferior ramous of pubis fracture were treated with lag screws placement. All the patients were divided into test group(with guided template) and control group(with general operation). There were 7 males and 3 females with an average age of (46.20±3.03) years old in test group and 6 males and 4 males with (48.50±2.25) years old in control group. There were 6 cases and 5 cases of superior and inferior branches fractures of pubic on the left side and 4 cases and 5 cases on the right side in two groups respectively. The operation time, perspective times and bleeding loss were compared between two groups.</p><p><b>RESULTS</b>The test group and the control group had no statistically significant relative to gender, age, fracture classification. The average time of surgery, average intraoperative fluoroscopy times, mean blood loss in test group were (31.0±5.3) min, (3.5±2.1) times, (75.6±10.5) ml respectively, and in control group were(55.0±6.8) min, (27.6±3.2) times, (85.5±12.5) ml respectively. There were significant Statistical differences between two groups(<0.05) in average operation time and average fluoroscopy times, however, mean blood loss had no significant differences between two groups(>0.05).</p><p><b>CONCLUSIONS</b>The personalized guide template based on 3D printing technology could realize precise placement of the lateral intramedullary lag screw fixation in the superior branch of pubic, also could save the operation time and reduce the times of radiation exposure of patients and surgeons.</p>
