Patients having severe arterial insufficiency (Grade 4 stenosis on CT angiography), pelvic infections and tumours, patients with past pelvic trauma and those who had previous pelvic surgery were excluded from the study. In total 200 hemi-pelvises were evaluated for the presence or absence of corona morti.Results: Overall, we included 100 patients in this series including 67 men and 33 women with mean age of 40.1±2.3 (ranging from 22-74) years. The arterial variant was identified on thin, 0.625-mm-thick images in 24 out of 100 patients studied (unilateral in 20 patients and bilateral in 4 patients; 28 out of 200 hemipelvises evaluated, having an incidence of 14%). We found that the distance of corona mortis artery from the symphysis was significantly greater for women compared to men, both on right (p=0.034) and left sides (p=0.046).Conclusion: Corona mortis may be prospectively identified at contrast-enhanced multidetector CT especially in pelvic trauma patients and help guide subsequent endovascular embolization or surgical interventions.}, keywords = {Pelvic fracture,Trauma,Haemorrhage,Vascular intervention,Embolization}, url = {https://beat.sums.ac.ir/article_46771.html}, eprint = {https://beat.sums.ac.ir/article_46771_8207367b42de33793f01f6a9bd8c1e04.pdf} }
