Modifications morphologiques dans l'hydrosalpinx expérimental.

Hydrosalpinges were mechanically induced in rabbits by ligation of the proximal and distal ends of the oviduct. Isthmic and ampullary biopsies were obtained at 2, 4 and 6 months after ligation. Deciliation and decrease of epithelial height were observed in the ampulla, but not in the isthmus. Microstereological study shows a decrease of both the number and the relative volume of capillaries in the ampullary muscularis. Considering the parallelism of time and localization between deciliation and reduction of vascularization, we suggest that epithelial deciliation is caused by vascular disorders. Our study shows also adrenergic denervation occurring in the muscularis.
