![]() Ultrasound is a very useful modality in the diagnosis of varicose veins and has revolutionized the treatment and management of venous insufficiency syndrome. After several months the body has absorbed the vein and it is not visible on ultrasound anymore. This is how venous disease is diagnosed.Ī week or so after the procedures another ultrasound is performed, this time to check for vein closure and to make sure there are no complications or blood clots. The sonographer has the patient reproduce this through the Valsalva movement (bearing down) multiple times throughout the procedure. In ultrasound, this is an easy, important way to distinguish varices from the GSV and SSV because tortuous. This phenomenon can be visualized on ultrasound by using doppler, which can tell what direction the blood is flowing. Varicose veins are often dilated and tortuous. When you have chronic venous insufficiency syndrome, the valves have stopped working and every time there is increased abdominal pressure, the valves won’t hold the blood where it is, and it all rushes towards the feet. There are valves throughout the veins, and when there is increased pressure on the veins, the valves will stop the blood from going back to the feet. Venous testing for reflux is highly dependent on. When there is increased abdominal pressure, for instance, taking a deep breath, the diaphragm presses down on the lower venous system, decreasing flow, just for a moment, and when breath is exhaled, the pressure is released from the lower venous system, and the blood rushes back to the heart. Gastrocnemius vein perforators often connect to the SSV or GSV varicosities complicating the treatment of vein. The amount of blood returning to the heart varies at any moment, as this is achieved by breathing. The heart pumps the blood from the arteries to the Reflux in a vein identified using color doppler.Įxtremities, and the veins take the blood back to the heart. Reflux in the veins is when blood is going in the wrong direction (towards the feet) when it should be flowing up towards the heart. The starting and ending point of all the veins are evaluated, and the flow checked for reflux. The legs are checked for any superficial or deep blood clots. The sonographer evaluates all the deep and superficial veins in the legs. The patient does stand for part of the ultrasound when the back of the legs are being evaluated. This simulates standing, which increases venous pressure on the legs, and the blood flow patterns can be evaluated more accurately than laying down flat on a bed, which creates 0% hydrostatic pressure and the flow patterns would be minimalized. ![]() When the exam is started, the sonographer adjusts the bed to what’s referred as the reverse Trendelenburg position, which is with the foot of the bed much lower than the head of the bed. Patients can expect to have an ultrasound at all of their appointments. ![]() Ultrasound is excellent for diagnosing varicose veins and is used throughout the treatment plan. Some very common questions new patients have when they come in for their first appointment are “What are you looking for? How can you tell if I have varicose veins?”. ![]()
