Lymphatic vessels around the uterus: D2-40 (podoplandin) immunohistochemistry using elderly cadavers
open access
Abstract
Using D2-40 immunohistochemistry, we examined the morphology of lymphatic vessels (LVs) in, along and around the uterus of 10 donated female cadavers (mean age, 85 years). All these women had 1 or 2 children with vaginal delivery, but the other obstetrics information was unknown. When compared with the bladder, vagina and the subperitoneal tissue, the percentage area of LVs in a 3 × 2 mm square including the hot spot was extremely high along the uterine artery and superficial uterine vein, in spite of the silent physiology of the elderly uterus. Notably, the LVs along the uterine artery and superficial uterine vein were highly dilated and embedded in the tight connective tissue around the artery and vein. In contrast, the LVs were separated from the artery and vein in the so-called vesico- -uterine ligament. Thus, surgical separation of the LVs from the artery and vein, i.e., skeletonisation, appears very difficult along the uterine artery and superficial uterine vein. This may become a major factor limiting the future application of robot-assisted surgery for uterine cancers.
