Lower extremity atherosclerosis occlusive disease is a group of chronic ischemic diseases caused by atherosclerosis that leads to narrowing and occlusion of the arterial lumen, the main causative factors include diabetes, hypertension, hyperlipidemia, obesity, smoking, etc. Among them, the lower extremity atherosclerosis occlusive disease caused by diabetes is called diabetic foot. The traditional treatment method is amputation, which affects the quality of life of patients and brings great pain and burden to their families and society. How to achieve good results The interventional department of our hospital uses modern interventional techniques to treat lower limb atherosclerosis and diabetic foot, including CT angiography (CTA), digital subtraction angiography (DSA) to check the location and degree of arterial stenosis and occlusion, lower limb arterial thrombolysis through femoral artery placement, intra-arterial plaque spinotomy, long micro balloon dilation, stent implantation and other interventional We have achieved satisfactory results by opening and dilating narrowed or occluded blood vessels through femoral artery placement, intra-arterial plaque spinning, long micro balloon dilation, stent implantation and other interventional techniques, combined with drug treatment, to improve the ischemic state of the lower limbs, prolong the distance of painless walking, promote ulcer healing and prolong the survival time of limbs. What is lower extremity deep vein thrombosis and pulmonary embolism Lower extremity deep vein thrombosis is a condition in which blood clots abnormally in the deep veins of the lower extremities causing blockage of the blood vessels and affecting the venous return to the heart. The thrombus dislodged into the pulmonary artery can cause pulmonary artery obstruction called pulmonary embolism, and the two together are called venous thromboembolism. It is mostly seen in patients after major surgery or trauma, prolonged bed rest, limb braking, patients with advanced tumors or those with significant family history. What are the clinical manifestations of lower extremity deep vein thrombosis and pulmonary embolism? The affected extremity is swollen, the skin may be blue-purple in severe cases, the skin temperature may rise, the pain may be aggravated after activity, which may be improved by elevating the affected extremity, and occasionally there are symptoms such as fever and accelerated heart rate, etc. If pulmonary embolism occurs, it may manifest as chest tightness, chest pain, difficulty in breathing or even endanger the patient’s life. How to prevent and treat quickly and effectively The Department of Interventional Medicine of our hospital adopts the most advanced interventional treatment technology to treat venous thromboembolism. A retrievable filter is placed in the inferior vena cava to prevent fatal pulmonary embolism, which ensures the smooth implementation of orthopedic surgery and thrombolysis of the deep vein and pulmonary artery of the lower limbs. At the same time, we use deep vein catheter to remove and dissolve the thrombus in the vein, and pulmonary artery catheter to remove and dissolve the thrombus in the pulmonary artery, so as to open the deep vein of the lower extremity in the shortest time, preserve the function of the venous valve to the maximum extent, dissolve the thrombus in the pulmonary artery, relieve the symptoms of pulmonary embolism, and prevent the patient from life threatening, and combine with anticoagulation and blood circulation treatment to make the patient recover in a short time, shorten the hospitalization time, and improve the The combination of anticoagulation and blood circulation treatment enables patients to recover within a short period of time, shortens hospitalization time, improves clinical efficacy and reduces recurrence rate.
