Summary
This study reveals the human spleen has two main venous lobes and 5-8 segments, each with distinct draining veins. Understanding this splenic venous system aids surgical planning and anatomical knowledge.
Area of Science:
- Anatomy
- Vascular Biology
- Surgical Anatomy
Background:
- The splenic venous system's detailed anatomical structure is crucial for surgical interventions and understanding splenic physiology.
- Previous studies have provided foundational knowledge, but a comprehensive description of intrasplenic venous territories is lacking.
Purpose of the Study:
- To investigate and delineate the anatomical organization of the human splenic venous system.
- To identify distinct venous territories, segments, and their drainage patterns within the spleen.
- To describe the modes of confluence of intrasplenic vessels forming the splenic vein.
Main Methods:
- Corrosion casting technique was employed to visualize the intricate vasculature of the human splenic venous system.
- Detailed anatomical dissection and analysis of the cast specimens were performed.
Main Results:
- Confirmation of two primary venous territories (lobes) within the spleen, separated by an avascular plane.
- Identification of 4-8 smaller venous territories (segments) within each lobe, also demarcated by avascular planes, with a mean of five segments.
- Description of four distinct patterns of intrasplenic vessel confluence contributing to the formation of the splenic vein.
Conclusions:
- The human spleen exhibits a segmented venous architecture, organized into distinct territories and sub-territories.
- This detailed anatomical understanding of the splenic venous system is vital for precise surgical approaches and anatomical education.
