Anterior tibial acupressure edema
Introduction
Introduction Pre-temporal edema is one of the clinical manifestations of primary deep venous insufficiency of the lower extremity. Primary deep venous insufficiency is a new category of venous lesions first proposed by Kistner (1980). Mainly due to the free edge of the valve in the deep vein, elongation, sagging, sagging, so that under the action of gravity, the two opposite leaflets can not be tightly aligned in the middle of the lumen, resulting in deep vein reflux lesions. Causes congestion and high pressure in the venous system of the lower extremities resulting in a series of clinical signs and symptoms.
Cause
Cause
Weak vein wall, venous valve defects, and elevated superficial vein pressure are the main causes of superficial varices. Weak vein walls and venous valve defects are a manifestation of weak systemic support tissues and are associated with genetic factors. The gravity of the blood column, as well as any acquired factors that enhance the effect of gravity, such as long-term standing work, heavy physical labor, pregnancy, chronic cough, habitual constipation, etc., can subject the valve to excessive pressure, gradually relax, and the valve is normally closed. Damaged. When the circulating blood volume often exceeds the load of reflux, it can also cause an increase in pressure and a dilated vein. As a result, the free edge of the leaflets cannot be closed when closed, thereby forming a relative insufficiency. When the great saphenous vein valve at the junction of the sacral femoral vein is destroyed and closed, the valve of the distal and traffic veins can be affected. Even the small saphenous vein is affected by the branch.

Clinical manifestations:
Symptoms and signs similar to simple superficial varices appear, but the larger saphenous veins are more pronounced and severe.
1. Shallow varicose veins This is the earliest pathological change. Most of the superficial veins along the anatomical distribution of the saphenous vein and/or small saphenous vein are dilated and elongated, and the stroke is distorted, and some spherical expansion may occur. The varicose veins can be combined with infection due to slow blood flow leading to thrombotic superficial phlebitis.
2. Swelling, pain and swelling This is a characteristic manifestation of deep venous insufficiency. There are obvious weakness, soreness, discomfort or pain in the lower limbs. Sometimes there may be twitching of the calf muscles, uniform swelling of the calves, and shiatsu edema before sputum. Symptoms are aggravated in the afternoon and walking. It can be relieved in the morning, rest, and raising the affected limb. Symptoms occur more frequently during the summer hot season.
3. Skin Nutritional Changes Skin nutrient changes include skin atrophy, desquamation, pigmentation, skin and subcutaneous tissue induration, eczema and ulceration. If combined with venous insufficiency in the ankle, these changes can be accelerated. Highly dilated Superficial veins are easily caused by mild trauma or self-piercing and are difficult to stop by themselves.
Diagnosis
Differential diagnosis
Hard non-recessed edema plaques in the anterior and posterior tibia: the hard non-depressed edema of the anterior and posterior tibia is a diffuse type of mucinous edema before the iliac crest. Edema plaque.
Pre-temporal black spot: Pre-ankle black spot is one of the complications of diabetes, itchy skin, prone to long lice, and a characterization of the pre-anterior dark spot. When you touched a black piece on your leg, it quickly disappeared. It has not disappeared yet, and it is black. The front of the legs is black. Many people with diabetes have this kind of performance.
