Due to the general overnutrition, lack of exercise, and love to drink sugary Drinks, and many people have the habit of smoking, which has caused a significant increase in the number of patients suffering from blockage of the cardiovascular and peripheral arteries. Not only the cardiovascular and cerebrovascular blocks are blocked, but even the arteries of the lower limbs are blocked.
A 67-year-old Mr. Zhang had abnormal throbbing pain in his right leg. It was believed that the cold weather caused rheumatic soreness. He wanted to massage , Hot compress and painful ointment to relieve, but on the third day, the right foot began to numb, and the soles of the feet also felt cold, so I had to be sent to the hospital for emergency with the company of my family, and the result was diagnosed as lower limb arterial obstruction.
Seriously blocked arteries of the lower extremities are "foot stroke"
Mr. Zhang’s lower limb arteries Obstruction is commonly known as "foot stroke". It is more common in patients who smoke, are older than 60, suffer from hypertension, diabetes, etc. In particular, smoking and diabetes are the most harmful. According to clinical statistics, the incidence of lower limb arterial obstruction caused by these two reasons is higher than that of ordinary people.3 to 4 times higher. Therefore, poor eating habits, excessive intake of high-fat and high-calorie foods, and people who drink and smoke are all high-risk groups for "foot stroke".
What are the symptoms of lower limb arterial obstruction?
Lower limb artery obstructionIn the early stage of the disease, it may just be that the lower limbs often feel cold and numb, and the leg muscles will spasm, which is commonly known as foot cramps, but these symptoms are not It is not serious and is often ignored by patients or mistaken for lower limb fatigue caused by excessive exercise.
However, if the ischemic condition persists and does not improve, then the patient will experience intermittent pain in the thigh, calf or foot after walking a long distance or exercising for a period of time Limp situation. This is because the patient has barely enough blood supply to the lower limbs, but after exerciseIncreased oxygen demand of the tissues and insufficient blood supply will cause symptoms such as claudication.
and As the condition worsens, the patient may later experience foot pain even when walking a short distance, but numbness and pain in the legs and feet>Especially at night and when the weather is cold, the pain will be more intense, requiring a lot of painkillers to relieve. At this time, the color of the leg skin changes, there is no blood color, or even turns purple or black. If the condition is more serious, it may occur such as cold lower limbs, weakened pulse, edema of the affected limb, or skin wounds that do not heal for a long time > And other symptoms, and eventually become so severe that lower limbs are blackened, necrotic, and even co-infected, facing the fate of amputation.
What check should be done for lower limb arterial obstruction?
Usually patients with lower extremity arterial obstruction may have diseases in other parts such as heart coronary artery, cerebral blood vessel and renal artery, so they should be examined by other systems. The inspection items for lower limb movement obstruction include:
1, Inspection: Check the upper and lower limbs Temperature difference, chromatic aberration, and hair growth.
2. Blood vessel pulse palpation: From the dorsal foot artery, posterior tibial artery, popliteal artery to femoral artery pulse, you can roughly know the vascular blockage Part)
3. Check the blood pressure ratio of the upper and lower limbs.
4. B-ultrasound and exercise volume test of peripheral blood vessels in the affected area.
In addition, further examinations include angiography and magnetic resonance imaging.
How to treat lower limb arterial obstruction?
When the arteries of the lower extremities are blocked to intermittent claudication, it is necessary to start active treatment, and the treatment method is not only taking In addition to drugs such as vasodilators, platelet inhibitors, metabolite scavengers, and prostaglandin E1 (PGE1) to relieve symptoms, when the patient's intermittent claudication cannot be improved by drugs or the symptoms worsen, or when diabetes has been ill for more than 10 years Therefore, surgical procedures such as balloon dilation, arterial plaque removal, stent placement, or dorsal artery bypass surgery should be considered.
Regardless of the type of treatment, there is the possibility of bleeding or re-embolization after the operation, so continue to take anticoagulant or antiplatelet therapy.
