Variation in Branching Pattern of Splenic Artery - A Cadaveric Study

Abstract

Background: The spleen receives its only circulation from the splenic artery. The biggest branch of the celiac axis, its trajectory is one of the most intricate in the body. It travels in the opposite direction of the superior border of the pancreas. It operates in several rotational motions or circles. Due to the spleen's importance in preventing infections, spleen-preserving procedures such segmental resection and partial spleen removal are now being explored. Therefore, the present study's goal was to look at the characteristics of the polar and major segmental branches (number, size and lengths).

Methodology: The study's focal point was the department of Anatomy the Krishna Institute of Medical Sciences, karad. To remove the spleens from the abdominal cavity, they were separated from their various associations and the splenic courses were cut off, no less than 5 cm from the spleen's hilum. The overall number of major segmentation and polar branching of the splenic arteries was recorded. The outside diameter of segmentation branching and polar arteries was measured at an offset of a centimetre from the branch's origin. The measures were taken using the Digital Vernier Calliper. The average, the range, and percentage for each parameter were calculated.

Results: We counted the principal segmental branch within the splenic artery in 119 cadaver spleens and found that there were just two main segmentations branching in 70.6% of the spleens. In 40.3% of the spleens from human deceased people, the inferior polar artery was identified, and in 22.7% of the spleens, the superior polar artery. The spleen from the studied human cadaver had dimensions ranging from 1.28±0.54 m for the superior and 1.21±0.45 mm for the inferior polar arteries.

Conclusion: This investigation improves the present data of the morphological characteristics of the splenic artery's segmentation subsidiaries, which is significant since various splenic saving exercises depend on a superior comprehension of the vascular engineering of the spleen..
