Some people have bruises on their calves that look like bunches of green earthworms, which is typical of varicose veins in the lower extremities. This disease is a common vascular disease, the incidence rate is as high as 30% and mostly seen in middle and old age; the main manifestations are: the leg veins are tortuous and dilated, bulging in the shape of earthworms, lumps, early may only have cosmetic changes, late will appear various symptoms, such as: calf soreness, edema, skin becomes melanin deposition, chronic eczema itching, varicose veins rupture and bleeding, and even lower limb ulcers for a long time (commonly known as “old rotten leg”). The underlying cause: high venous pressure in the lower extremities Veins are the conduits for blood return, and there are many “one-way switches (venous valves)” to ensure that blood flows only in the direction of the heart and does not flow backwards. If the long-term venous pressure in the lower extremities destroys this “one-way switch”, the blood will reflux, and the huge pressure will cause the veins of the lower extremities, which were originally straight, to bulge and bend and form varicose veins. Special reminder: varicose veins are never just unsightly. If varicose veins are allowed to develop, a vicious cycle will eventually arise – varicose veins will be produced by elevated venous pressure in the lower limbs, and varicose veins will in turn aggravate venous hypertension by poor blood flow back to the lower limbs. This vicious circle eventually causes skin nutrient disorders, resulting in itching, eczema, and even chronic skin ulcers that do not heal over time. Teachers, salesmen, traffic police, medical personnel and other people are prone to varicose veins in their middle and old age due to long-term standing, so it is especially important to pay attention to vascular health care and prevention of varicose veins. Preventive measures: decompressing the veins of the lower extremities Everything that can help reduce the pressure in the veins of the lower extremities can prevent the occurrence of varicose veins in the lower extremities. The calf muscles are known as the “second heart” of the human body and contract like a huge pressure pump to squeeze the blood from the lower extremities back to the heart. Sitting or standing for a long time makes the blood flow in the lower limbs poor, while walking or flexing and extending the ankle joint can make the calf muscles contract to help the blood flow back. Middle and old age people should avoid sitting or standing for a long time, and should move their lower limbs after standing or sitting for a while to promote blood return. Patients with early manifestations of varicose veins should elevate their lower limbs as much as possible when resting, and they can also wear sequential decompression elastic stockings to promote blood return, reduce the pressure in the veins of the lower limbs, and slow down the development of varicose veins. Effective treatment: “Drugs to cure varicose veins” cannot be believed It is important to choose a reasonable and effective treatment plan for varicose veins in the lower limbs. There are no drugs that can straighten varicose veins, so it is not advisable to blindly believe in those drugs that claim to “fundamentally treat varicose veins in the lower limbs”. The most effective treatment is to improve circulation in the lower extremities by diverting blood to the deeper, larger veins, and under this premise, the more minimally invasive the treatment option, the more acceptable it is to the public. The following minimally invasive treatment options are worth using: 1) foam sclerotherapy, using polyglactin foam sclerotherapy to inject varicose veins; 2) endovenous closure treatment, including laser and radiofrequency, such as endovenous laser closure performed by the imported laser generator of the vascular disease center; 3) spot stripping, using imported surgical instruments to remove varicose veins through an incision as large as the eye of a needle.
