Outline of Final Research Achievements

The lymphatic drainage pattern of normal canine and feline organs in the body cavity was investigated in an anatomical study using Indian ink, and usefulness of three dimensional computed tomographic analysis (3D-CT) and Laparoscope with contrast media for visualization of sentinel lymph nodes was examined in clinical setting. The CT analysis showed that the lymphatic pathways draining directory from the injection sites of small dose of contrast medium were quickly and sufficiently topographic 3D-CT lymphography provided detailed anatomical information on individual lymphatic channels and nodes without overlaps with the surrounding structures. Thus, visualization of lymph drainage using simple, noninvasive 3D-CT is useful for easy identification of the lymph drainage route and is necessary not only to determine the most appropriate surgical treatment of mammary tumors, but also to determine an accurate postsurgical prognosis.
