Abstract:

Objective     To observe the corona mortis in inguinal hernia patients under laparoscopic surgery with CT angiography (CTA), and investigate the anatomic features and clinical significances of this variant vascular anastomosis in patients with different types of hernia. Methods      A total of 48 patients with inguinal hernia (direct hernia or oblique hernia) admitted in our department between June 2015 and October 2016 were enrolled in this study. They were 33 males and 15 females, at a mean age of  61.0±15.5 years. CTA scanning was performed before the operation. All patients underwent laparoscopic hernia repair. The conditions of corona mortis were collected, and analyzed with clinical data and radiological results. Results     Among the 48 cases, there were totally 56 sides involved (21 sides of direct hernia and 35 sides of oblique hernia). The occurrence rate of corona mortis was 58.9% (33/56). The distance from the blood vessels to pubic symphysis midpoint was 54.4±6.9 mm. The average diameter of arteries in the corona mortis was 2.2±0.8 mm, obviously smaller than that of the veins (2.8±1.1 mm, P<0.05). The occurrence of corona mortis was significantly lower in the patients with direct hernia than those with oblique hernia (P<0.05), so were that of corona mortis in arteries (P<0.05). The males had significantly higher occurrence of corona mortis in veins than the females (P<0.05), while older onset age, larger blood vessel diameter, older in those with direct than oblique hernia were found in male patients (P<0.05). Conclusion     The occurrence rate of corona mortis is higher in the oblique than direct hernia patients, and in the males than the females. The blood vessels of corona mortis are involved in blood supply of the abdominal wall and can slow its degradation.
