    en.wikipedia.org/wiki/Pelvic_congestion_syndrome

    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]

  3. Endovenous laser treatment - Wikipedia

    en.wikipedia.org/wiki/Endovenous_laser_treatment

    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 This causes the vein to contract, and the optical fiber is slowly withdrawn.

  4. Varicocele - Wikipedia

    en.wikipedia.org/wiki/Varicocele

    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.

    Getting blood back up through a tight 90 degree turn isn’t easy, and so blood backs up, and the back up of venous blood around the testicle causes the testicular vein to enlarge and get tortuous where it starts to loop back and forth on itself - and it makes the scrotum look like a bag of worms which gets larger with standing and smaller when ...

    en.wikipedia.org/wiki/Telangiectasia

    Pregnancy: Pregnancy is a key factor contributing to the formation of varicose and spider veins. Changes in hormone levels are one of the most important reasons women are more likely to develop varicose veins during pregnancy. There is an increase in progesterone, which causes the veins to relax and potentially swell more easily. [6]

  8. Sclerosing lymphangitis - Wikipedia

    en.wikipedia.org/wiki/Sclerosing_lymphangitis

    The condition involves the hardening of a lymph vessel connected to a vein in the penis. It can look like a thick cord and can feel like a hardened, almost calcified or fibrous, vein, however it tends to not share the common blue tint with a vein. It can be felt as a hardened lump or "vein" even when the penis is flaccid, and is even more ...

  9. Ultrasonography of chronic venous insufficiency of the legs

    en.wikipedia.org/wiki/Ultrasonography_of_chronic...

    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).
