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 are the symptoms of varicocele?

The symptoms of varicocele vary depending on the severity of the patient's condition. Clinically, most varicocele patients have no obvious symptoms or no symptoms at all, and varicocele is often discovered during physical examinations. A small percentage of varicocele patients exhibit noticeable symptoms. The primary symptom is a feeling of heaviness or discomfort in the testicles, especially after prolonged walking or standing. The pain becomes more pronounced, but it will decrease or even disappear after lying down and resting. Some varicocele patients may not show symptoms but present with infertility. Varicocele is then discovered through physical examinations or related medical tests.

What is the cause of pain in varicose veins?

Varicose veins can sometimes cause localized pain, and there are several reasons for this pain. One reason is the formation of blood clots in the varicose veins, which can cause very obvious pain. Additionally, the affected area feels harder, not soft. When we say soft, it's like the softness of one’s lips; if it feels like the tip of the nose or the forehead, then it's considered very hard. In such cases, it indicates that the vein is not empty but contains a solid blood clot, which can cause pain. Another situation is if there is poor venous return in the proximal segment, causing the veins to fill significantly in a short time. This can also pull on the nerves outside the vein wall, leading to a sensation of pain.

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.

What are the symptoms of varicocele?

If the patient has mild varicocele, they often have no symptoms and it is not easily detected; in such cases, no special treatment is needed. However, with moderate or severe varicocele, the patient may experience a dragging pain in the testicles, especially after intense physical activity, prolonged sitting, or standing, which makes the pain more pronounced. During a physical examination, twisted, worm-like clusters of veins can be felt within the scrotum. Patients with varicocele should undergo further routine semen analysis to assess if the semen quality is affected. If sperm quality is impacted, it could lead to a decline in male fertility, and surgical treatment should be considered when necessary.
