ANALYSING ANATOMICAL MORPHOMETRY AND MORPHOLOGY OF FISSURES ON THE SURFACE OF LIVER

Abstract

Background: There are fissures on the liver's many surfaces, including the porta hepatis, ligamentum venosum fissure, 
and/or ligamentum teres hepatis, which are frequently observed on the liver's visceral surface.  
Aim: The objective is to evaluate the morphology and anatomical morphometry of the liver's surface fissures in cadaveric 
sections. 
Methods: Thirty liver specimens from cadavers frozen in 10% formalin were obtained from regular undergraduate 
dissection sessions for the study. The depth, breadth, and length of the fissures were measured for morphometry, while 
the shape, content at the base of the fissure, and any other related characteristics were measured for morphology. A scale, 
divider, and thread were used for each measurement. 
Results: The ligamentum teres hepatis fissure's average depth, breadth, and length were 1.9 cm, 4.5 mm, and 5.1 cm, 
respectively, and were positioned either linearly or occasionally obliquely. The ligamentum venosum fissure was 
curvilinear and positioned vertically, with typical dimensions of 2.5 cm for depth, 7 mm for breadth, and 6.1 cm for length. 
The porta hepatis's circumference measured 10.6 cm and had an oval to elliptical shape. Rouviere's sulcus, also known as 
Gan's fissure, was curvilinear and observed in 76.6% of the individuals. Other accessory fissures were observed as 
variations on the posterior surface of the right hepatic lobe, aside from Gan's fissure. 
Conclusion: The current study comes to the conclusion that fissures on the liver's surface are essential markers for 
evaluating and identifying the vascular systems during various surgical operations and imaging examinations. During 
radiological evaluations and surgical procedures, radiologists and surgeons can benefit from the morphometric and 
morphological differences seen.
