Introduction

Introduction The ankle is prone to uncontrollable ankle infection, which is the symptom of the lower extremity arteriosclerosis obliteration stage 1 (slightly complaining period). The patient only feels that the skin temperature of the affected limb is lower than cold, or mildly numb, and fatigue is easy after exercise. The extremities are prone to foot and foot infections and are not easy to control. Atherosclerotic plaque is formed on the inner wall of the arterial vessel, and as the plaque increases, the lumen is narrow, the patency of the tube is affected, the blood flow to the lower limb is reduced, and the stenosis is to a certain extent or even completely blocked. If the blood flow can not meet the needs, there will be symptoms of lower limb ischemia.

Most patients with suspected lower extremity arteriosclerosis obstruction are advised to go to the vascular surgery of a regular hospital for a definitive diagnosis. Usually, the specialist will ask for detailed medical history and physical examination, such as pulse palpation of the limb and abdominal and femoral-? Auscultation is necessary for diagnosis. Depending on the strength or disappearance of the pulse and the appearance of murmurs, the doctor may also make preliminary symptoms based on symptoms such as rest pain, paresthesia or numbness, as well as dystrophy, ulcers or gangrene in the limbs. Diagnosis of lower extremity arteriosclerosis obliterans. However, in order to further clarify the lesion and determine the treatment plan, the following main auxiliary examinations need to be improved.

Lower extremity vascular color ultrasound: This test is non-invasive, painless, and can basically determine the location of the lower extremity vascular lesions, the degree of stenosis, and blood flow in the blood vessels.

/ index: This test is very simple and has the advantages of non-invasive, tolerable, and repeatable. We generally think that the / index 0.9 considers the presence of lower limb ischemia.

Multi-slice spiral CT angiography: Through the three-dimensional reconstruction technique after examination, blood vessel filling in the lower extremity can be understood through revascularization, and the location and stenosis of the lower extremity vascular stenosis can be understood to guide the determination of the clinical treatment plan.

Lower extremity angiography: It is a "golden indicator" for the diagnosis of vascular diseases, especially for vascular diseases with more complicated conditions, but it is not easy to accept because of its invasive examination.

Diagnosis

Differential diagnosis

It is easy to be confused with the following diseases: Due to peripheral vascular neuropathy, the skin of diabetic patients is easily damaged, and it is not easy to find and heal itself. Therefore, diabetic patients are prone to various skin and soft tissue infections, clinically with sputum, sputum, and folliculitis. Bacterial infections such as sweat gland inflammation and papillary dermatitis are common, and various purulent infections can occur; fungi are also common pathogens of skin infections in diabetic patients, manifested as athlete's foot, handcuffs, and women's genital candida albicans. Infection, etc. In the case of minor trauma such as pressure ulcers on the soles of the feet, the construction of the toenails is too short, and improper treatment of the ankles can cause secondary infections, and it is difficult to control after infection.

Athlete's foot is the most common superficial fungal pathogen caused by fungal infection of the foot. It is called athlete's foot or moisture in China. The main pathogens of this disease are Trichophyton rubrum, Fusarium oxysporum, Gypsum-like Trichophyton and Trichophyton rubrum. In addition, it is reported frequently by Candida albicans. The majority of the disease is caused by young and middle-aged people. Older children are less common in children, which may be related to the less activity of these people and the drier between the toes.

The doctor may make preliminary decisions based on the strength or disappearance of the pulse and the occurrence of murmurs, as well as symptoms such as resting pain, paresthesia or numbness, as well as dystrophies, ulcers or gangrene of the limbs.
