The Department of Peripheral Vascular Intervention, which is responsible for diseases occurring in the blood vessels of the circulatory system throughout the body except the heart, such as arteriosclerotic stenosis occlusion, arterial dilatation diseases such as aneurysm or entrapment, venous thrombosis, varicose veins and various vascular malformations, also includes diseases that can be treated by vascular interventional means, etc. If you have any of the following symptoms, it is recommended that you promptly visit the vascular intervention department to investigate whether there is vascular disease. Cold, numb and painful limbs: including cold, numbness and pain after limb activity. Pain after limb activity is also called “intermittent claudication”, which means that the painful limb muscles appear after walking for a certain distance and can be relieved by standing and resting for a while, and then the pain is repeated after walking for a certain distance. In addition, if there is no activity that appears obvious pain, and even affect the night rest, may indicate the development of serious disease, the above symptoms suggest that you may have lower limb atherosclerosis occlusion, if not timely treatment may even develop to amputation, need to seek medical attention. Acute thoracic back pain: Acute thoracic back pain may be caused by clamping, sudden onset, high risk, the lesion often extends rapidly to the proximal end leading to pericardial tamponade and death of the patient, or to the distal extension blocking the branch vessels of the aorta with corresponding parts of ischemia, in which Stanford type A aortic clamping 24-hour mortality rate > 35%, more than half of the patients die within 48 hours, 30 days The mortality rate is >95%. Therefore, early management and selection of appropriate treatment is the key to save lives. single medical conservative treatment of TAAD is not effective, and once diagnosed, active surgical treatment should be performed. Acute thoracic back pain: Acute thoracic back pain may be caused by entrapment, with sudden onset and high risk. The lesion often extends rapidly proximally leading to pericardial tamponade and causing death of the patient, or extends distally blocking the branch vessels of the aorta with ischemia in the corresponding area. The mortality rate is >95%. Therefore, early management and selection of appropriate treatment is the key to save lives. single medical conservative treatment of TAAD is not effective, and once diagnosed, active surgical treatment should be performed. Limb swelling: especially limb edema that manifests itself as decreasing in the morning after waking up and worsening in the afternoon, or various sudden limb swelling, beware of venous thrombosis and need prompt medical consultation. Deep vein thrombosis mostly occurs in the lower limbs. The clinical manifestation is often unilateral (left side is more common) swelling and pain in the lower limbs. Prolonged sitting, long flights, major surgical procedures, tumors, prolonged bed rest, and trauma are all factors that contribute to venous thrombosis. The dangers of venous thrombosis (especially deep vein thrombosis) include pulmonary embolism, post-thrombotic sequelae, and femoral bruising.
