All surgeons operating in the retropubic region should have a thorough understanding of the anatomical characteristics and surgical implications of a corona mortis.Ĭorona mortis Hernia repair Obturator vessels Pelvic fracture Pelvic lymphadenectomy Retropubic region Vascular anatomy.Ĭopyright © 2017 Elsevier Ltd. The corona mortis is more common in Asia (59.3%) than in Europe (42.8%) and North America (44.3%).Īs a corona mortis is present in an about half of all hemi-pelvises, it is important to consider the possibilities of its presence when undertaking surgical procedures and plan accordingly to avoid injuries. A venous corona mortis is more prevalent than an arterial corona mortis (41.7% vs. This review highlights key mechanisms that have been. Although the clinical and laboratory characteristics of COVID-19 patients have been well characterized, the pathophysiological mechanisms underlying disease severity and progression remain unclear. The overall prevalence of the corona mortis in hemi-pelvises is high (49.3%). The global epidemiology of coronavirus disease 2019 (COVID-19) suggests a wide spectrum of clinical severity, ranging from asymptomatic to fatal. Data extracted included investigative method, prevalence of the corona mortis vessels among hemi-pelvises (overall, arterial only, venous only, and combined), distance from the corona mortis to pubic symphysis, and assessment of gender, side, laterality, and ethnicity subgroups.Ī total of 21 studies (n=2184 hemi-pelvises) were included in the meta-analysis. The aim of our meta-analysis was to provide comprehensive data on the prevalence, anatomical characteristics, and ethnic variations of the corona mortis vessel.Īn extensive search was conducted through the major electronic databases to identify eligible articles. Due to the significant variation in this collateral circulation, detailed anatomical knowledge of the corona mortis is vital to enhance the prevention of possible iatrogenic errors in hernia repair and other pubic surgical procedures. Corona mortis is a highly variable vascular connection between the obturator and external iliac or inferior epigastric arteries or veins located behind the superior pubic ramus in the retropubic space (space of Retzius).
