Insights
This study details the human spleen
Area of Science:
- Anatomy
- Vascular Surgery
- Radiology
Background:
- The splenic artery's branching pattern is crucial for understanding spleen vascularization.
- Previous anatomical studies provide a basis for systematizing splenic vasculature.
- Accurate anatomical knowledge aids surgical interventions and diagnostic imaging.
Purpose of the Study:
- To systematically map the branches of the human splenic artery.
- To define the vascular territories supplied by each splenic artery branch.
- To compare findings with existing anatomical literature.
Main Methods:
- Corrosion casting technique applied to human spleen specimens.
- Detailed analysis of the splenic artery's primary and secondary branching patterns.
- Identification and mapping of vascular territories irrigated by arterial branches.
Main Results:
- Confirmation of two primary (lobar) branches of the splenic artery.
- Identification of an average of six secondary (segmental) branches.
- Defined vascular territories corresponding to lobar and segmental branches.
Conclusions:
- The human spleen exhibits a consistent pattern of two primary vascular divisions.
- An average of six segmental territories are supplied by secondary branches.
- These findings contribute to a refined anatomical understanding of splenic vascularization.
Abstract:
The authors have conducted a corrosion cast study of the human spleen to systematize the branches of the splenic artery and the vascular territories irrigated by them. The existence of two primary divisional or lobar branches of the splenic artery and their respective territories or lobes is confirmed. The secondary or segmental branches and their vascular territories were studied; an average of 6 segmental territories was found. These findings are compared with those reported in the literature.
