Segmental splenic arteries originate outside the spleen, offering surgical access for ligation. This anatomical understanding aids in splenic dearterialization for hemostasis and spleen preservation.

Area of Science:

  • Anatomy
  • Vascular Surgery
  • Surgical Anatomy

Background:

  • The spleen's segmental vasculature is crucial for targeted surgical interventions.
  • Understanding the extracapsular course of splenic arteries is vital for splenic preservation techniques.

Purpose of the Study:

  • To anatomically characterize the extracapsular branching patterns of human splenic segmental vessels.
  • To evaluate the feasibility of surgical access to splenic segmental arteries for dearterialization.

Main Methods:

  • Analysis of 102 human spleen autopsy specimens.
  • Application of corrosion casting and post-mortem arteriography techniques.

Main Results:

  • Superior terminal splenic branches averaged 2.8 divisions; inferior branches averaged 2.3 divisions.

  • Extracapsular segmental branches ranged from 4.0-16.7 mm in length and 0.4-2.2 mm in caliber.
  • Polar arteries were identified in 31.3% (superior) and 20.6% (inferior) of specimens.

    • Conclusions:

    • Segmental splenic arteries exhibit an extrasplenic origin and course.
    • The defined anatomical features support surgical access for ligation and segmental dearterialization.
    • This facilitates splenic preservation during hemostatic procedures.
