Article Abstract
Background: The obturator artery (OA) often presents multiple anatomical variations. These can be an atypical origin, variable anastomosis, or abnormal course within the pelvis.
Methods: This study aimed to report a rare arterial variation in a Puerto Rican female cadaver that showed two abnormal obturator arteries with multiple pelvic branches. The OA emerged from the anterior branch of the internal iliac artery, which typically runs anteroinferior along the lateral wall of the pelvis to the upper part of the obturator foramen.
Results: The atypical OA described in this report provided two variant branches. Abnormal obturator artery I (AOAI) emerged first and gave rise to three additional branches, while abnormal obturator artery II (AOAII) emerged second and gave rise to two other branches.
Conclusions: Identifying these accessory arteries is essential for surgical interventions, particularly within the field of gynecology and urogynecology. Knowledge regarding anatomical variations within this region must be assessed preoperatively to decrease the risk of iatrogenic injury.

Introduction: The profunda femoris artery (PFA) is the largest branch of the femoral artery supplying the thigh. The study reports a rare occurrence of bilateral double profunda artery in a male cadaver, aiming to inform surgeons of such variations to avoid complications during surgical interventions.
Methods: This study was conducted during routine dissections using 5-10% formalin-fixed lower limbs of a male cadaver at the Department of Anatomy, College of Medicine and Health Sciences, United Arab Emirates University, UAE.

BackgroundDelivery assist catheters are a new class of devices designed to better navigate tortuous segments and reach the clot interface in mechanical thrombectomy. The RED 72 aspiration catheter with SENDit technology is one such example. SENDit is a novel tapered obturator used instead of a microcatheter to bring up the RED 72.

Introduction: The corona mortis (CM) artery or ("crown of death") is a vascular anastomosis between the obturator artery and either the external iliac or inferior epigastric artery. An anastomosis is defined as one or more vessels that merge with other vessels before dividing. The CM's clinical significance arises from its potential of bleeding you can have if injured while performing any pelvic or acetabular surgeries.

Background: The aim of this study was to provide a detailed analysis of the topographical anatomy of the inferior epigastric artery (IEA), including its origin pattern, morphometric parameters, spatial relationships to anatomical landmarks and perforating branches.
Materials And Methods: Data from 75 patients who underwent computed tomographic angiography of the abdomen and pelvis were analyzed. A total of 142 sides that met the eligibility criteria were evaluated.
