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]
Endovenous laser treatment treats varicose veins using an optical fiber that is inserted into the vein to be treated, and laser light, normally in the infrared portion of the spectrum, [1] shines into the interior of the vein. This causes the vein to contract, and the optical fiber is slowly withdrawn.
Produces abdominal collateral veins to bypass the blocked inferior vena cava and permit venous return from the legs. Determine the direction of flow in the veins below the umbilicus. After pushing down on the prominent vein, blood will: flow toward the legs → caput medusae; flow toward the head → inferior vena cava obstruction.
In the male varicocele, this plexus of veins drains blood from the testicles back to the heart. The vessels originate in the abdomen and course down through the inguinal canal as part of the spermatic cord on their way to the testis. Varicoceles occur in around 15% to 20% of all men. [3] [4] The incidence of varicocele increase with age ...
Lower extremity varicose veins is the condition in which the superficial veins become tortuous (snakelike) and dilated (enlarged) to greater than 3 mm (0.12 in) in the upright position. [24] Incompetent or faulty valves are often present in these veins when investigated with duplex ultrasonography.
In the cases of veins or arteries, traumatic fistulas usually occur between artery and vein. Portacaval anastomosis , by contrast, is a veno-venous anastomosis between a vein of the portal circulation and a vein of the systemic circulation , which allows blood to bypass the liver in patients with portal hypertension , often resulting in ...
It results when the vein dilates secondary to a vein wall disease or when normal functioning of the valves, which serve to keep blood flowing to the heart and to prevent reflux, become damaged and/or incompetent (the dilation of a vein will prevent valves from closing properly).
The external iliac vein is crossed by the ureter and internal iliac artery which both extend towards the middle. In males it is crossed by the vas deferens and in females the round ligament and ovarian vessels cross it. Psoas major lies to its side, except where the artery intervenes. [4] The external iliac vein may have one valve, but often ...
