Accessory Saphenous Vein
The anterior accessory saphenous vein is a special anterior tributary of the great saphenous vein (GSV), draining the antero-lateral face of the thigh. It becomes very often insufficient, causing important varicose veins with an autonomous course and often is the only insufficient vein present on a patient. Structure Usually it joins GSV very near the saphenous-femoral junction at the saphenous arch or can drain directly in the femoral vein. It can drain below the saphenous arch or in a GSV tributary. Sometimes it can drain in the external pudendal vein (which can communicate with an ovarian vein) and be the reason of a varicose disease of the thigh secondary to pelvic varicose disease. At the superior 1/3 of the thigh it is located under the superficial fascia, like the GSV, but becomes very superficial below this level. In contrast with other tributaries, its wall is histologically saphenous-type with a thick media, running parallel and external to the GSV. The vein can be ...

Great Saphenous Vein
The great saphenous vein (GSV, alternately "long saphenous vein"; ) is a large, subcutaneous, superficial vein of the leg. It is the longest vein in the body, running along the length of the lower limb, returning blood from the foot, leg and thigh to the deep femoral vein at the femoral triangle. Structure The great saphenous vein originates from where the dorsal vein of the big toe (the hallux) merges with the dorsal venous arch of the foot. After passing in front of the medial malleolus (where it often can be visualized and palpated), it runs up the medial side of the leg. At the knee, it runs over the posterior border of the medial epicondyle of the femur bone. In the proximal anterior thigh inferolateral to the pubic tubercle, the great saphenous vein dives down deep through the cribriform fascia of the saphenous opening to join the femoral vein. It forms an arch, the saphenous arch, to join the common femoral vein in the region of the femoral triangle at the sapheno-femoral ...

Varicose Veins
Varicose veins, also known as varicoses, are a medical condition in which superficial veins become enlarged and twisted. These veins typically develop in the legs, just under the skin. Varicose veins usually cause few symptoms. However, some individuals may experience fatigue or pain in the area. Complications can include bleeding or superficial thrombophlebitis. Varices in the scrotum are known as a varicocele, while those around the anus are known as hemorrhoids. Due to the various physical, social, and psychological effects of varicose veins, they can negatively affect one's quality of life. Varicose veins have no specific cause. Risk factors include obesity, lack of exercise, leg trauma, and family history of the condition. They also develop more commonly during pregnancy. Occasionally they result from chronic venous insufficiency. Underlying causes include weak or damaged valves in the veins. They are typically diagnosed by examination, including observation by ultrasound ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Femoral Vein
In the human body, the femoral vein is a blood vessel that accompanies the femoral artery in the femoral sheath. It begins at the adductor hiatus (an opening in the adductor magnus muscle) as the continuation of the popliteal vein. It ends at the inferior margin of the inguinal ligament where it becomes the external iliac vein. The femoral vein bears valves which are mostly bicuspid and whose number is variable between individuals and often between left and right leg.

Ovarian Vein
The ovarian vein, the female gonadal vein, carries deoxygenated blood from its corresponding ovary to inferior vena cava or one of its tributaries. It is the female equivalent of the testicular vein, and is the venous counterpart of the ovarian artery. It can be found in the suspensory ligament of the ovary. Structure It is a paired vein, each one supplying an ovary. * The right ovarian vein travels through the suspensatory ligament of the ovary and generally joins the inferior vena cava. * The left ovarian vein, unlike the right, often joins the left renal vein instead of the inferior vena cava.Lampmann LE, Smeets AJ, Lohle PN.

Mickey Mouse Sign
Mickey Mouse sign is a medical sign resembling the head of Mickey Mouse, the Walt Disney character. Presented for the very first time at the CHIVA's Meeting, Berlin 2002 by Dr. Lurdes Cerol, this sign has been described as the image at the groin when a dilated accessory saphenous vein (ASV) exists: the common femoral vein (CFV) represents the head of Mickey Mouse while the great saphenous vein (GSV) and the dilated accessory saphenous vein (ASV) represent the ears. The presence of a Mickey Mouse sign has been a great diagnostic clue to check ASV insufficiency. Some authors, inspired by this sign, described an ecographic "Mickey Mouse View" at the saphenofemoral junction in the groin: the common femoral vein (CFV) represents the head of Mickey Mouse while the great saphenous vein (GSV) and the femoral artery (CFA) represent the ears. But it can be seen in different regions of the body: * Midbrain of progressive supranuclear palsy (PSP). * Polyostotic Paget's disease (Paget's diseas ...

Ultrasonography
Ultrasound is sound waves with frequencies higher than the upper audible limit of human hearing. Ultrasound is not different from "normal" (audible) sound in its physical properties, except that humans cannot hear it. This limit varies from person to person and is approximately 20 kilohertz (20,000 hertz) in healthy young adults. Ultrasound devices operate with frequencies from 20 kHz up to several gigahertz. Ultrasound is used in many different fields. Ultrasonic devices are used to detect objects and measure distances. Ultrasound imaging or sonography is often used in medicine. In the nondestructive testing of products and structures, ultrasound is used to detect invisible flaws. Industrially, ultrasound is used for cleaning, mixing, and accelerating chemical processes. Animals such as bats and porpoises use ultrasound for locating prey and obstacles. History Acoustics, the science of sound, starts as far back as Pythagoras in the 6th century BC, who wrote on ...
