Pelvic congestion syndrome, also known as pelvic vein incompetence, is a long-term condition believed to be due to enlarged veins in the lower abdomen. [1] [7] The condition may cause chronic pain, such as a constant dull ache, which can be worsened by standing or sex. [1] Pain in the legs or lower back may also occur. [1]
The straight angle between the ovarian vein (or testicular vein in males in the case of varicocoele) and the renal vein has been proposed as a cause of decreased blood return. [citation needed] A related diagnosis is nutcracker syndrome where the left renal vein is described as being compressed between the aorta and the superior mesenteric ...
The uterine vein is found in the cardinal ligament of the uterus. It travels through the broad ligament of the uterus to the lateral abdominal wall. [1] It drains into the internal iliac vein. [1] [2] The uterine vein forms a venous plexus around the cervix. [2] It follows a similar course to the uterine artery. [3] Lymphatic vessels are ...
There's also a significant increase in the blood volume during pregnancy, which tends to distend veins, causing valve dysfunction which leads to blood pooling in the veins. Moreover, later in pregnancy, the enlarged uterus can compress veins, causing higher vein pressure leading to dilated veins.
The arcuate vessels of the uterus are a component of the blood supply of the uterus. They are arteries and veins that branch from the uterine arteries and veins, respectively, with additional anastomoses from the ovarian arteries and veins, [ 2 ] and penetrate and assume a circumferential course in the myometrium .
The uterine plexuses lie along the sides and superior angles of the uterus between the two layers of the broad ligament, and communicate with the ovarian and vaginal plexuses. They are drained by a pair of uterine veins on either side: these arise from the lower part of the plexuses, opposite the external orifice of the uterus, and open into ...
The pampiniform plexus (from Latin pampinus 'tendril' and forma 'form') is a venous plexus – a network of many small veins found in the human male spermatic cord, and the suspensory ligament of the ovary. In the male, it is formed by the union of multiple testicular veins from the back of the testis and tributaries from the epididymis.
Uterine Compression of IVC and Pelvic Veins. Displacement of PMI by Uterus. Uterine enlargement beyond 20 weeks' size can compress the inferior vena cava, which can markedly decrease the return of blood into the heart or preload. As a result, healthy pregnancy patients in a supine position or prolonged standing can experience symptoms of ...
