71-year-old zhang aunt diabetes more than 30 years.two years ago, she suffered leg cramps;after walking a distance, the lower extremities and tired and tired, also pins and needles, acid bilges;often consciously toes or plantar have ants in climbing, tingling in the occasional.
it was not long before, aunt zhang's left foot is always cold, cold to the touch, feel is not as sensitive as normal skin.went to the hospital to see a doctor, the doctor told her, this is caused by diabetes vascular lesions, commonly known as diabetic foot.
the doctor gave her medicine, but didn't improve much after taking this medicine.later left toes began to burst out stench ichor, left foot to a dark, numb.
she is very anxious, ask around.someone said to do surgery amputation, someone says to do surgery vascular bypass surgery, others say feasible minimally invasive angioplasty of the lower limbs.she didn't mind at the moment.
zhang aunt these symptoms, how did this happen?
lower limb cold, blood vessels could be blocked 50%
diabetic foot is caused by diabetic lower limb nerve damage or vascular injury, is a more severe atherosclerotic lesions, developing very quickly.
as you know, if the blood supply to the brain of the carotid artery problems occur, the consequences will be very serious, have life risk.and there is something wrong with the lower extremities vascular, although less dangerous, but has a very big impact on the quality of life.
, for example, if a side lower limb vascular stenosis of about 50%, the patient can appear the lower limb chills;again development bottom go to, there will be intermittent claudication, go after 50 or 100 meters, feet began to pain, sit down and rest and get better;to continue resting pain will occur and awake at night.if not treated, that can appear on foot gangrene, wound is not healing and face the possibility of amputation.
a high incidence of diabetic foot, gangrene of opportunity in the aftermath of the disease are also much higher than normal people.so, diabetes patients have feet, feet hemp, cold symptoms such as pain, it should be checked to the hospital for treatment.
like to blow the balloon through the blood vessel
in case of diabetic foot, it should be treated as soon as possible.amputation just to save lives and to adopt the method that is used in other treatment is invalid.
like zhang aunt this kind of situation, the first thing to do is to strictly control blood sugar, reducing sugar, the damage to the blood vessels and nerves to improve limb ischemia symptoms, prevent gangrene.foot have burst, should be sterile surgical dressing, cooperate external use gangrene series paste, promote wound healing.
for there has been a narrow lower limb blood vessels, there are two ways, namely the vascular bypass and intracavitary plasty.what is the difference between?
- <p>vascular bypass surgery(arterial revascularization)</p>
is in the lesions and normal blood supply artery segments distal vascular stenosis artery between the erection of a self or hematopoietic pipeline bridge, to improve the body distal blood flow.the vascular patency rate is about 60%, but the implementation is the premise of distal vessels must be unobstructed;in addition, the operation on the patient injury is bigger, now is not in the first place.
- <p>(percutaneous valvuloplasty intracavitary minimally invasive treatment)</p>
is a root in the patient's thigh femoral artery do the size of a grain of puncture point, under the x-ray to intravascular into thread, and finally make it through the blood vessels;then along the balloon over the guidewire system, balloon expansion, like blowing balloons blow the occlusion of blood vessels, the blood flowing, ultimately achieve the goal of expanding lesion blood vessel.for appropriate lesion blood vessel parts, still can put bracket, so we can ensure long-term patency.
currently, intracavitary plasty is especially suitable for older, physical condition is not very good, accompanied by other complications of the patients.
in general, when a patient with vascular lesions(narrow or blocked), we try to select simple solutions, can rely on drug treatment, not the preferred invasive treatment;but if the drug therapy, you should consider the treatment of invasive, and it should start from the simple.
