Fig. 6

A schematic view of efferent mammary lymphatic cannulation. The sketch indicates the cannula placement location in the efferent mammary lymphatic vessel relative to the locations of the lymphatic ligation and a mammary lymph node adjacent to the right mammary gland. A segment of the efferent mammary lymphatic vessel near to the mammary lymph node was ligated using suture. The external pudendal vessels and lymphatics can show curved segments in the deep inguinal region, not demonstrated on this diagram. The efferent lymphatic vessels of the mammary lymph nodes (on both sides) enter the iliofemoral lymph node(s). The cannula was inserted into the lymphatic upstream from the ligation and secured with ligations (only one ligation is shown in this schematic picture). The sketch is superimposed over a photograph of a ewe post-surgery. The image is positioned with cranial to the right
