The cisterna chyli is the abdominal origin of the thoracic duct, and it receives the bilateral lumbar lymphatic trunks. Anatomically and surgically the cisterna chyli is an important structure but very fewer studies reported in literature,so that we undertake this study. In this study we observed the presence, position with respect to the vertebral bodies and the main lymphatic tributaries forming the cisterna chyli in 45 cadavers from 3 different medical colleges in costal Andhra, of these 15 were female and 13 were male cadavers. We found Cisterna chyli was present in
6(40%) out of 15 female bodies, and 14 (46.6%) out of 30 male bodies. To sum up cisterna chyli was present in 20
(44.4%) out 45 cadavers dissected (44.4%). The position of the cisterna chyli was at L1-T12vertebrae in 10 adult
cadavers. The position of the cisterna chyli was at T12-T11 vertebrae in 6 adult cadavers. The position of the
cisterna chyli was at L2-L1 vertebrae in 4 adult cadavers, the main lymphatic tributaries forming the cisterna chyli based on M.Loukas Types In 9 cadavers (20%) the thoracic duct arose from the confluence of the lumbar and intestinal trunk (Type I) . In 27 cadavers (60%) it was formed by the confluence of two ascending lumbar lymph trunks and intestinal trunk joined the thoracic duct (Type II). In 9 cadavers (20%) the thoracic duct ascended from a plexus formed by the lumbar and intestinal trunks (Type III). The reports documented in this study were different compare to the literature. The variations in the presence, positions and the main lymphatic tributaries forming the cisterna chyli are important for anatomists, surgeons and radiologists during their diagnosis and surgeries related to
the cisterna chyli.
