The ovarian artery arises from which artery

Everyone should know that the ovaries are important reproductive organs of women, but in fact the ovaries are supplied by the ovarian arteries. The ovarian artery mainly refers to the artery below the renal artery, which branches out through the fallopian tube mesentery to supply the fallopian tube. The ovarian artery is generally of similar proportion to the mesentery. The things to note about the ovarian artery are generally that it is not well developed, etc.

The arteries supplying the ovaries are separated from the abdominal aorta (the left side may come from the left renal artery.

The left ovarian vein drains into the left renal vein, so left-sided pelvic varicose veins are more common). Behind the peritoneum, it runs forward and downward along the psoas major muscle to the pelvic cavity, crosses the ureter and the lower segment of the common iliac artery, passes through the pelvic infundibulum ligament, and runs inward and horizontally through the ovarian mesentery to enter the ovarian hilum. The ovarian artery branches out into several branches within the mesosalpinx to supply the fallopian tubes, and its distal end anastomoses with the ascending ovarian branch of the uterine artery near the uterine horn.

The positional relationship of the ovarian artery to the adjacent arterial openings.

Previous literature reports showed that OA often opened at the level below the renal artery. 2~35mm below the inferior mesenteric artery, some OA openings are lower than the superior mesenteric artery opening, some are lower than the renal artery opening, the left and right OA openings are higher than the inferior mesenteric artery and at the same level as the inferior mesenteric artery, and some are lower than the inferior mesenteric artery. The description of the relationship between OA and the opening of the inferior mesenteric artery is helpful for finding the opening of OA during catheterization.

The clinical significance of ovarian artery involvement in blood supply to pelvic diseases.

The results of this study showed that OA can participate in the blood supply of various pelvic tumors and bleeding diseases, including gynecological tumors. The following situations occur more frequently: (1) internal iliac artery angiography shows absence or hypoplasia of one or both uterine arteries; (2) uterine bleeding diseases related to pregnancy and childbirth, such as abnormal placental position, ectopic pregnancy, hydatidiform mole, etc.; (3) previous history of pelvic or gynecological surgery, especially after ligation of the internal iliac or uterine artery; (4) after uterine artery embolization; (5) uterine fibroids located at the bottom of the uterus; (6) any tumor originating from the pelvic structure, especially those with huge pelvic tumors and extensive infiltration.
