Ankle pitting edema

Introduction When there is excessive accumulation of body fluid in the subcutaneous tissue space, the skin is pale, swollen, wrinkles become shallow, the local temperature is low, and the elasticity is poor. Use a finger to press the skin (such as the internal hemorrhoids, anterior or anterior region), if present. The depression is called pitting edema or frank edema. Edema refers to excessive accumulation of body fluids in the extravascular tissue space, which is one of the common clinical symptoms. Unlike obesity, edema is characterized by a significant depression when the finger presses a small area of the subcutaneous tissue (such as the anterior side of the calf).

Cause

After the edema of the depression is released, the depression will take a few seconds to resolve. This is due to the depression of edema, there is more free water in the subcutaneous tissue space, because the local pressure is increased, the free water is moved to the lower pressure, so the depression occurs, the finger is released, the free water The time to return to the original place is the time for the depression to recover.

Cardiac edema, edema begins with the sagging part of the body and gradually develops into systemic edema. In general, the lower extremity can be depressed edema, which is most obvious. Pregnancy-induced hypertension syndrome can initially manifest as an abnormal increase in body weight (recessive edema), more than 0.5 kg per week. If there is too much fluid in the body, it will lead to clinically visible edema. The edema is mostly caused by the sacral part, and gradually extends to the calf, thigh, genital area, and abdomen, and the depression is called "depression edema".

Differential diagnosis

Non-recessed edema is caused by deposition of protein in the interstitial space. It is also called mucinous edema. It is more common in hypothyroidism. In severe cases, it is mucinous edema, so it is also called "mucus edema". In coma, it is called "mucus edema." Sexual coma, the clinical manifestations of the milder are not obvious, severe cases may appear characteristic non-depressed edema caused by the infiltration of mucopolysaccharide in the skin, such as characteristic mucous edema, facial expression, apathy, unresponsiveness, rough skin, pale complexion Eyelids, face edema, narrow eye cracks, blinking effort, thick lips, thin hair, dry and shedding, 1/3 of the eyebrows fall off, hoarseness, monotony such as frog sound, hearing loss, chills, cold, intelligence Decreased, drowsiness or loss of eye, dizziness, bradykinesia, dysregulation, loss of appetite, constipation, shortness of breath, fatigue, thickening of nails, non-depression edema of both lower extremities, weight gain, slow Achilles tendon reflex, loss of libido, impotence , women with irregular menstruation or amenorrhea, infertility and other symptoms of reduced metabolism. Depressed edema is generally a diffuse distribution of liquid in the interstitial space of the body, so the pressure is concave, the mechanism is that tissue interstitial fluid production is greater than recovery. Most of the edema is this, such as renal edema, cardiogenic edema. Cardiac edema and edema begin with the ptosis of the body and gradually develop into systemic edema. In general, the lower extremity can be depressed edema, which is most obvious. Pregnancy-induced hypertension syndrome can initially manifest as an abnormal increase in body weight (recessive edema), more than 0.5 kg per week. If there is too much fluid in the body, it will lead to clinically visible edema. The edema is mostly caused by the sacral part, and gradually extends to the calf, thigh, genital area, abdomen, and the depression is called depression edema.
