Brodie–Trendelenburg Percussion Test
The Brodie–Trendelenburg percussion test is a medical test to determine valvular incompetence in superficial veins. A finger is placed over the lower (distal) part of the vein being examined. The upper (proximal) part of the vein is then tapped (percussed). If the impulse is felt by the finger placed at the lower end, it indicates incompetence of valves in that vein. The test is used as part of the examination of varicose veins. It is named after Sir Benjamin Collins Brodie and Friedrich Trendelenburg Friedrich Trendelenburg (; 24 May 184415 December 1924) was a German surgeon. He was son of the philosopher Friedrich Adolf Trendelenburg, father of the pharmacologist Paul Trendelenburg and grandfather of the pharmacologist Ullrich Georg Tr ....

Vein
Veins are blood vessels in humans and most other animals that carry blood towards the heart. Most veins carry deoxygenated blood from the tissues back to the heart; exceptions are the pulmonary and umbilical veins, both of which carry oxygenated blood to the heart. In contrast to veins, arteries carry blood away from the heart. Veins are less muscular than arteries and are often closer to the skin. There are valves (called ''pocket valves'') in most veins to prevent backflow. Structure Veins are present throughout the body as tubes that carry blood back to the heart. Veins are classified in a number of ways, including superficial vs. deep, pulmonary vs. systemic, and large vs. small. * Superficial veins are those closer to the surface of the body, and have no corresponding arteries. * Deep veins are deeper in the body and have corresponding arteries. * Perforator veins drain from the superficial to the deep veins. These are usually referred to in the lower limbs and feet. * ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Superficial Vein
Superficial veins are veins that are close to the surface of the body, as opposed to deep veins, which are far from the surface. Superficial veins are not paired with an artery, unlike the deep veins, which are typically associated with an artery of the same name. Superficial veins are important physiologically for cooling of the body. When the body is too hot, the body shunts blood from the deep veins to the superficial veins to facilitate heat transfer to the body's surroundings. Superficial veins are often visible underneath the skin. Those below the level of the heart tend to bulge out, which can be readily witnessed in the hand, where the veins bulge significantly less after the arm has been raised above the head for a short time. Veins become more visually prominent when lifting heavy weight, especially after a period of proper strength training. Physiologically, the superficial veins are not as important as the deep veins (as they carry less blood) and are some ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Sir Benjamin Collins Brodie, 1st Baronet
Sir Benjamin Collins Brodie, 1st Baronet, (9 June 178321 October 1862) was an English physiologist and surgeon who pioneered research into bone and joint disease. Biography Brodie was born in Winterslow, Wiltshire. He received his early education from his father, the Rev Peter Bellinger Brodie; then choosing medicine as his profession he went to London in 1801 and attended the lectures of John Abernethy and attended Charterhouse School. Two years later he became a pupil of Sir Everard Home at St George's Hospital, and in 1808 was appointed assistant surgeon at that institution, on the staff of which he served for over thirty years. In 1810 he was elected a fellow of the Royal Society, to which in the next four or five years he contributed several papers describing original investigations in physiology. In 1834, he was elected a foreign member of the Royal Swedish Academy of Sciences. At this period he also rapidly obtained a large and lucrative practice and from time t ...

Friedrich Trendelenburg
Friedrich Trendelenburg (; 24 May 184415 December 1924) was a German surgeon. He was son of the philosopher Friedrich Adolf Trendelenburg, father of the pharmacologist Paul Trendelenburg and grandfather of the pharmacologist Ullrich Georg Trendelenburg. Trendelenburg was born in Berlin and studied medicine at the University of Glasgow and the University of Edinburgh. He completed his studies at the Charité - Universitätsmedizin Berlin under Bernhard von Langenbeck, receiving his doctorate in 1866. He practiced medicine at the University of Rostock and the University of Bonn. In 1895 he became surgeon-in-chief at the University of Leipzig. Trendelenburg was interested in the history of surgery. He founded the German Surgical Society in 1872. Trendelenburg was also interested in the surgical removal of pulmonary emboli. His student Martin Kirschner performed the first successful pulmonary embolectomy in 1924, shortly before Trendelenburg's death. He died in 1924 of cancer ...

Trendelenburg Test
The Trendelenburg Test or Brodie–Trendelenburg test is a test which can be carried out as part of a physical examination to determine the competency of the valves in the superficial and deep veins of the legs in patients with varicose veins. __TOC__ Procedure With the patient in the supine position, the leg is flexed at the hip and raised above heart level. The veins will empty due to gravity or with the assistance of the examiner's hand squeezing blood towards the heart. A tourniquet is then applied around the upper thigh to compress the superficial veins but not too tight as to occlude the deeper veins. The leg is then lowered by asking the patient to stand. Normally the superficial saphenous vein will fill from below within 30–35 seconds as blood from the capillary beds reaches the veins; if the superficial veins fill more rapidly with the tourniquet in place there is valvular incompetence below the level of the tourniquet in the "deep" or "communicating" veins.
