Insights
The corona mortis, an anastomosis between obturator and external iliac vessels, was found in 84% of cadaver dissections. This vascular connection, crucial for pelvic surgery, occurred in the majority of specimens studied.
Area of Science:
- Anatomy
- Vascular Surgery
- Surgical Anatomy
Background:
- The corona mortis is a significant vascular anomaly in the pelvic region.
- Understanding its prevalence and location is critical for preventing surgical complications.
Purpose of the Study:
- To determine the occurrence and anatomical location of the corona mortis.
- To quantify the incidence of arterial and venous connections within the corona mortis.
Main Methods:
- Dissection of fifty human cadaver halves.
- Identification and measurement of anastomoses between the obturator and external iliac vascular systems.
Main Results:
- Anastomoses (corona mortis) were present in 84% of the dissected specimens.
- Venous connections (70%) were more common than arterial connections (34%).
- The average distance from the symphysis to these anastomotic vessels was 6.2 cm.
Conclusions:
- The corona mortis is a frequent finding, with a high prevalence of venous connections.
- Awareness of this vascular network's common occurrence and location is essential for surgeons operating in the pelvic area.
Abstract:
Fifty cadaver halves were dissected to determine the occurrence and location of the corona mortis. Anastomoses between the obturator and external iliac systems occurred in 84% of the specimens. Thirty-four percent had an arterial connection, 70% had a venous connection, and 20% had both. The distance from the symphysis to the anastomotic vessels averaged 6.2 cm (range, 3-9 cm).
