STUDY ON ORIGIN, COURSE, BRANCHING PATTERN AND MORPHOMETRY OF SPLENIC ARTERY AND ITS BRANCHES SUPPLYING THE SPLEEN-A CADAVERIC STUDY
Author: Gangadhara, Rajasekhar P., Hemasankar C.
Objectives: 1.To measure the length of splenic artery and its branches supplying the spleen till they enter the hilum. 2. To note the origin and course of the splenic artery. 3. To note type of branching pattern of the splenic artery and occurrence of polar artery. Methods: Splenic artery & its branches supplying spleen were dissected neatly, traced till the hilum and measured with the digital vernier calliper. Other branches of splenic artery were not considered in the study. Results: Mean length of the splenic artery trunk was 7.45cms (Range: 2-11cm), lobar artery 3.24cms (Range: 1.2-8cms), segmental artery 1.21cms (Range: 0.4- 3cms), trabecular artery 0.59cm (Range: 0.3-2.5cms). The splenic artery trunk was bifurcated in 80 %( 24), trifurcated in 16.66 % ( 5) and quadrifurcated in 3.3 %( 1). Lobar artery was bifurcated in 63.33%, trifurcated in 33.33% and quadrifurcated in 3.33%. Segmental artery was bifurcated in 93.33% and trifurcated in 6.66%. In All the specimens the splenic artery was arising from coeliac trunk. 63.3 %( 19) of specimens showed supra-pancreatic course and 36.6 % (11) showed retro-pancreatic course of splenic artery. 26.6 %( 8) of specimens showed only superior polar artery, 36.6 %( 11) showed only inferior polar artery, 16.6 %( 5) showed both polar arteries and 20 %( 6) of specimens has no polar artery. Conclusions: knowledge of vascular supply for the spleen is very important for the surgeons during partial resections of spleen and it is also important for radiologist for performing preoperative arteriography and splenic artery embolization..
