Clinical implications of anatomic variations of the splenic artery
Surgery, Gynecology & Obstetrics
|January 1, 1989
Insights
An unusual path of the proximal splenic artery was found in 9 of 26 cadavers. This anatomical variation increases the risk of surgical injury during procedures in the lesser omentum.
Area of Science:
- Anatomy
- Surgical Anatomy
- Vascular Anatomy
Background:
- The lesser omentum is a critical surgical area.
- Understanding vascular anatomy is crucial for preventing iatrogenic injury.
- Aberrations in major arteries can pose significant surgical risks.
Purpose of the Study:
- To document the prevalence of aberrant splenic artery courses.
- To highlight the potential for iatrogenic injury due to splenic artery variations.
- To inform surgeons about anatomical risks in the lesser omentum.
Main Methods:
- Dissection of 26 adult cadavers.
- Detailed anatomical mapping of the lesser omentum and associated vasculature.
- Documentation of splenic artery course and variations.
Main Results:
- An aberrant course of the proximal splenic artery was identified in 9 out of 26 dissected cadavers (34.6%).
- These aberrant courses render the splenic artery more susceptible to accidental damage during surgery.
- The findings indicate a significant prevalence of this specific vascular anomaly.
Conclusions:
- The prevalence of splenic artery aberration warrants attention.
- Surgeons operating in the lesser omentum must be aware of potential splenic artery anomalies.
- Awareness and careful surgical technique can mitigate the risk of iatrogenic injury to the splenic artery.
Abstract:
An aberrant course of the proximal splenic artery was observed in nine of 26 adult cadavers dissected for mapping of the lesser omentum. Such an aberrant course makes the artery vulnerable to iatrogenic injury. In view of this relatively high prevalence of splenic artery aberration, it is suggested that surgeons operating in the area of the lesser omentum should keep in mind the possibility of its occurrence and the dangers that it may present.
