Varicose veins
Can you run if you have varicose veins in your lower legs?
Patients with simple varicose veins can run. The movement of muscles, especially during running when the calf muscles are active, can compress the deep veins, facilitating the emptying of these veins. This benefits the flow of blood in the superficial veins through the communicating veins back to the deep venous system, thus participating in the systemic circulation. Therefore, patients with varicose veins in the calves can still run in the majority of cases. However, there are exceptions. If a person experiences significant muscle pain, it is important to be cautious as there may be a thrombus in the muscle veins. If there is a thrombus in the muscle veins, and the return flow in the deep veins is obstructed, this may also cause varicose veins. In cases of fresh thrombosis, running might lead to the detachment of the thrombus. Thus, patients in such conditions are advised not to run until further evaluation is confirmed by an ultrasound examination.
Can venous varicosity be measured by CT?
Venous varicosities can undergo CT imaging, but generally, it's best to avoid injecting medication into the varicose veins. If the varicosities are in the lower limbs, a routine ultrasound examination is usually sufficient. To perform venous imaging with CT, medication is typically administered through the upper limbs. It moves through the general circulation, enters the arteries, reaches the peripheral tissues, and then flows back through the veins to allow imaging of the lower limb veins. This process is time-consuming, laborious, and costly; therefore, CT is generally not used to detect lower limb venous varicosities. However, CT can be used to examine venous abnormalities in other areas, such as problems with abdominal veins.
What does it mean when varicose veins occasionally have blocked blood flow?
The so-called varicose veins are caused by blood circulation blockages, which likely refers to local thrombus formation, leading to feelings of congestion in lower limbs, or caused by compression from above, such as tight clothing, exacerbating the obstruction of blood flow. This might result in increased surface tension of varicose veins in the lower extremities. Additionally, there might be some pain upon pressing, or even spontaneous pain. In such cases, differentiated treatment is required. For instance, if the issue is due to compressive clothing, like tight-knee socks or pants legs that are too tight, simply relieving the pressure should suffice. However, if a thrombus has formed causing increased local tension, pressing or massaging must be strictly avoided, as there is a risk the thrombus might dislodge and potentially lead to pulmonary embolism.
How should young people deal with varicose veins in the lower legs?
Firstly, for young people with varicose veins in the lower leg, it is recommended to go to the hospital for an ultrasound examination to check the condition of the deep veins. Additionally, consult a professional vascular surgeon to assess the severity. If the deep veins are unobstructed and the superficial varicose veins in the lower leg are not too severe, the doctor will suggest the patient wear medical compression stockings and continue with normal life activities. If the condition is more serious or there are certain issues with the deep veins, the doctor might recommend surgery. For such patients, it is important in daily life to avoid standing or sitting for long periods, and to avoid letting the legs dangle for too long. If standing, one can also step in place appropriately, which helps alleviate varicose veins. Also, when resting, take any opportunity to elevate the legs and avoid soaking feet in hot water.
Can varicose veins be detected by ultrasound B?
Ultrasound is currently the main examination method for varicose veins. It is non-invasive, safe, and affordable, making it one of the standard methods for assessing varicose veins. Besides viewing the superficial veins, it also allows visualization of the deformed deep veins within the muscles, enabling a basic assessment of the causes of varicose veins. Ultrasound now plays a crucial role in the treatment of varicose veins. Many new treatment methods, such as blood flow modulation techniques like wrist flexing, require high precision in ultrasound use. It is essential to locate the reflux points using ultrasound, and then specifically target these points for ligation.
How is varicocele treated?
The treatment of varicocele depends on the severity of the condition. Clinically, some varicocele patients do not exhibit obvious symptoms, or show no symptoms at all and are only diagnosed during physical examinations. These patients can generally be treated conservatively by avoiding standing for long periods, avoiding prolonged walking, and by wearing tight underwear to alleviate symptoms of varicocele. However, some patients with varicocele do exhibit clear symptoms, including discomfort and pain in the scrotum on the affected side, especially after long periods of walking. These symptoms can become more severe and may also be accompanied by abnormalities in semen quality. These patients generally require surgical intervention, such as high ligation of the veins.
What should I do about varicocele?
The treatment methods for varicocele vary based on the severity of the condition. Clinically, some patients with varicocele show no obvious symptoms and it is only discovered during a physical examination. These patients can generally be observed temporarily, and can also wear tight underwear or use a scrotal support to alleviate the condition. However, some patients do exhibit clear symptoms, such as a significant sensation of heaviness in the scrotum, especially after standing or walking for long periods, where the pain becomes more pronounced. These patients generally need to consider surgical treatment, where the main procedure involves high ligation of the spermatic vein. This can help alleviate symptoms and also improve the quality of semen.
Why does varicose veins sometimes feel like needle pricks?
In cases of varicose veins, the blood flow in the varicose veins is relatively slow. This blood, having undergone gas exchange, contains less oxygen and more carbon dioxide. If such blood remains in a local area for an extended period, it can potentially stimulate the nerves to some extent. Sometimes, including in varicose veins, if the blood flow pressure within these veins increases, it can also stimulate the nerves in the outer membrane of the blood vessels, leading to abnormal nerve discharges. Such incidents can manifest as brief, pin-like pain, not particularly intense, resembling the sensation of a needle prick. This condition is quite common and generally holds no special significance.
Can varicose veins cause leg swelling?
Varicose veins are a broad concept that is clinically divided into seven grades, from 0 to 6. Grade 0 is normal, grade 1 involves some capillary dilation, grade 2 is marked by clear varicose veins, and from grade 3 onwards, edema can occur. Generally, the causes of varicose veins vary. Some people suffer from what is called simple superficial varicose veins, primarily due to problems with the valves in the superficial veins. These patients may experience mild edema, limited to the ankle area. Others suffer from secondary varicose veins, following dysfunction of the valves in the deep veins or communicating veins. In deep veins, there can be reflux or obstruction. In such cases, it is possible to cause compressible edema in the front of the lower leg, commonly known as shinbone area.
Can varicose veins occasionally be invisible?
When varicose veins are mild in their early stages, if you wear compression stockings during winter, it's possible that the varicosities are not very noticeable occasionally when you take off the stockings. However, in more advanced stages, when there are clearly widespread and clustered varicose veins, they are difficult to conceal. However, if deep vein thrombosis occurs, causing tissue edema, the swollen surrounding tissues may obscure the varicose veins, making them less visible. Therefore, we need to judge based on the specific circumstances. Generally, just because varicose veins are occasionally not visible does not mean that the condition has healed.
