Uterine venous drainage network during hysterosalpingography

A 43-year-old women, G3P1, present to the hospital for a history of infertility for
2 years. During a hysterosalpingography using meglumine diatrizoate, the uterus appeared
normal, and bilateral distal tubal obstruction was seen (Figure 1). Besides, intravasation of the contrast revealed the drainage of arcuate vessels
into the ascending branch of uterine vein and deep uterine vein, and then into the
ovarian vein and internal iliac vein separately. The film also demonstrated the communicating
branches in uterine wall, the numerous branches of internal iliac vein, and an accompanying
vein of ovarian vein draining into the renal vein (Figure 2). The patients experienced mild pelvic pain during the procedure, and it resolved
spontaneously later.
