To establish the incidence of arterial corona mortis variant in angiographic studies being performed using a 64 slice CT scan machine in a series of patients.
This was a prospective cross-sectional study including 100 consecutive patients undergoing routine clinically indicated, standard protocol, CT-angiography for the abdominal aorta and/or lower limbs using a 64 slice CT scanner. 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.
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 (=0.034) and left sides (=0.046).
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.
在一系列患者中，利用64层CT扫描仪进行血管造影研究，确定动脉死亡冠变异的发生率。
这是一项前瞻性横断面研究，纳入100例连续接受常规临床指征、标准方案的64层CT扫描仪腹部主动脉和/或下肢CT血管造影的患者。患有严重动脉供血不足（CT血管造影4级狭窄）、盆腔感染和肿瘤、既往有盆腔创伤史以及既往有盆腔手术史的患者被排除在研究之外。总共对200个半骨盆进行了死亡冠存在与否的评估。
本系列共纳入100例患者，其中男性67例，女性33例，平均年龄40.1±2.3（22 - 74）岁。在100例研究患者中，有24例在0.625毫米厚的薄层图像上发现了动脉变异（20例为单侧，4例为双侧；在评估的200个半骨盆中有28个，发生率为14%）。我们发现，女性死亡冠动脉与耻骨联合的距离在右侧（=0.034）和左侧（=0.046）均显著大于男性。
在对比增强多排CT上可前瞻性地识别死亡冠，尤其是在盆腔创伤患者中，并有助于指导后续的血管内栓塞或手术干预。
