deep venous thrombosis
Diagnosis and treatment of deep venous thrombosis
Deep vein thrombosis is a blood does not normally in the deep vein deep venous lumen condensation, leading to partial or complete blockage. Good hair on the lower limbs, can cause lower extremity pain, swelling and a series of symptoms. The disease may be residual limb edema, secondary veins,Cable manufacturer dermatitis, pigmentation, stasis ulcers, venous gangrene, serious damage to people's health and labor. And it is a high recurrence and mortality risk of the disease. Beijing Hospital Ministry of health in Corran.
Accepted venous thrombosis three pathogenic factors: blood stasis, vein wall damage and high coagulation state, especially in the" blood stasis" in venous thrombosis plays a key role in the process of.
Deep venous thrombosis of lower extremities occurred in the human body, mainly because of the blood from the heart to start, the arterial system to lower extremity venous system, by reinfusion of blood back to the heart, which flows through the distance is the longest, the heart's pumping force to this region become relatively weak. And because of the gravity, easy occurrence of blood in the lower extremities of slow blood flow, in the vein stasis. If this time, has the" second heart" reputation of the calf muscles in resting condition, in all parts of the body to the same state, is easy to form the thrombus of lower limb vein relative.
Bilateral lower extremity, left lower limbs is more easily to the deep venous thrombosis, which is related to its anatomical position. The left common iliac vein was caught in the right common iliac artery and the gap between the sacrum, easy to make the left common iliac vein in front and back wall of the contact status, not only makes the left common iliac venous obstruction, but also the formation of venous intraluminal adhesions.
Deep venous thrombosis in high-risk population: operation after prolonged bed rest or inactivity; trauma, obesity, high blood lipids or over the age of 40 years old; myocardial infarction, heart failure, stroke, in patients with nephritic syndrome; patients with malignant tumor; with oral contraceptives, pregnancy, varicose veins or previous history of thrombosis, etc.. Operation and trauma patients especially complicated with lower limb deep venous thrombosis, acute thoracic abdominal large operation and a hip or knee replacement operation, hip fracture, severe trauma and acute spinal cord injury patients, is at a very high risk population of thromboembolism.
During pregnancy, increased uterine oppression in abdominal cavity, hinder the return of lower extremity blood, exacerbation of lower limb blood stasis condition. At the same time, during pregnancy, the body's blood secondary high condensate. Two factors synergies, lower the incidence rate of DVT greatly increases.
Deep vein thrombosis have any risk
Approximately 80% of patients with deep venous thrombosis without any clinical symptoms, but the sudden death is often the disease symptom and the sole clinical manifestation, causes of sudden death is "pulmonary embolism: in 70-90% patients with pulmonary embolism can check to the deep venous thrombosis. In the United States of America statistics: pulmonary embolism mortality rate is second only to cancer, coronary heart disease, in third. So deep vein thrombosis is referred to as a" silent killer".
In our country, with the structure of people's diet and lifestyle changes, deep venous thrombosis incidence increases by degrees every year. But the medical community to the understanding of the disease is far from enough, about 70% of the patient with pulmonary embolism were missed diagnosed or misdiagnosed as myocardial infarction, coronary heart disease, lung disease, about 30% of the patients died due to not timely diagnosis and treatment. Deep vein thrombosis of the lower extremity has what symptom
Lower limb swelling, pain and varicose veins of lower extremity DVT is three big symptoms, pain is falling down from pain or dull pain, varicose veins for the chronic stage of establishment of collateral circulation performance.靜脈曲張
