Linfadenectomia laparoscópica em cadela com neoplasia mamária

Linfadenectomia inguinoilíaca laparoscópica, após impregnação linfática com diferentes marcadores em cadelas hígidas

“…Another possibility is that there are micro lymph nodes, but as they were not reactive or were located for inclusion in the histological sections. These results emphasize the importance of further studies to better define the regions referred for collection, and the comparison of the lymphatic drainage mechanisms of healthy animals and those with mammary neoplasms, since the existence of micro lymph nodes in this region has been previously demonstrated (SOUZA et al, 2013).…”

“…There were no lymph nodes or lymphocytic accumulations in any of the samples. SOUZA et al (2013) performed the same technique of pelvic lymphadenectomy; however, this was performed only on the left side of a dog presenting mammary tumors in the abdominal and inguinal glands. Intradermal application of methylene blue dye 1% was performed on the largest tumor located in the inguinal mammary gland.…”

“…In these situations, the lymphatic system plays an important role in local tumor control as well as in cellular transport mechanisms, associated with the onset of metastasis in many types of cancer (HAIGH & GIULIANO, 2000). The formation of new lymphatic vessels resulting from lymphangiogenesis is also related to tumorigenesis (SOUZA et al, 2014).…”

Identification of intra-abdominal lymphatics in canine carcasses by laparoscopic fluorescence lymphography with intradermal and intrapopliteal ICG administration

“…The lymphatic dyes used in dogs included octafluoropropane-filled lipid microspheres [ 4 ], patent blue V [ 5 ], patent blue plus technetium [ 6 ], methylene blue [ 7 , 8 ], isosulfan blue [ 9 ], hemosiderin plus technetium [ 6 ], iopamidol [ 3 , 10 ], indocyanine green (ICG) [ 3 ], and ICG plus methylene blue [ 3 ]. The use of ICG as a direct near-infrared fluorescent marker in video surgery is still under investigation in dogs.…”
