In the strictest sense, vascular surgery should be called peripheral vascular surgery. It is responsible for diseases that occur in the blood vessels of the circulatory system other than the heart, such as arteriosclerosis and occlusion, aneurysm or entrapment and other arterial dilatation diseases, venous thrombosis, varicose veins and various vascular malformations, and also includes diseases that can be treated by vascular interventions. If you have any of the following symptoms, it is recommended that you promptly visit the vascular surgery 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”, that is, painful and sore limb muscles after walking for a certain distance, which 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 the pain is obvious without activity, and even affects the night rest, it 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, you need to promptly seek medical vascular surgery. Limb swelling: especially the limb edema which is reduced in the morning after waking up and aggravated in the afternoon, or various sudden limb swelling, should be careful of venous thrombosis and need timely 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. Limb or toe ulceration: If an elderly person with previous combined hypertension or diabetes develops a limb or toe ulceration due to an accidental injury that does not heal even after 1-2 weeks, it may also be a manifestation of lower limb atherosclerosis occlusion or diabetic foot, and promptly seek medical attention for vascular surgery, otherwise the ulceration will continue to expand and even threaten the limb or even life. Weakened pulse disappearance: Healthy people can palpate obvious arterial pulsation on the wrist or foot surface, if the pulsation is weakened or disappeared, it indicates arterial stenosis or blockage and requires prompt medical attention. Pulsating mass: If a pulsating mass is felt in the neck, limbs or abdomen, and the frequency of pulsation is similar to the heartbeat, it may indicate the presence of an aneurysm, which may even rupture and endanger life if left untreated. Finding “arterial plaque”: A small plaque can cause an organ infarction if it is found by ultrasound during a physical examination. “Small strokes” and “strokes”: Sudden onset of symptoms such as blurred eye vision, upper or lower extremity movement disorders, aphasia, and foot and mouth distortion, which can recover on their own, are called “small strokes” and are often “Stroke” – a precursor and danger signal of cerebral infarction, regardless of “mini-stroke” or “stroke”, it is necessary to see Vascular surgery except for carotid, vertebral artery or cerebrovascular lesions. Varicose veins: bruising of the limbs, even itching, blackening, rupture, inflammation of veins, etc. Acute chest and back pain: acute chest and back pain may be caused by entrapment, with sudden onset and high risk. The lesion often extends rapidly proximally leading to pericardial tamponade and death of the patient, or extends distally blocking the branch vessels of the aorta with ischemia in the corresponding area, where Stanford type A aortic entrapment has a 24-hour mortality rate >35%, more than half of the patients die within 48 hours, and 30-day 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. When your chest pain changes from shoulder-back-thoracic-back-waist-abdomen-lower limbs, and combined with mediastinal widening in chest film + elevated D-dimer in laboratory tests, we suggest you to consult vascular surgery as soon as possible and improve CTA of thoracic aorta in an emergency to clarify whether there is aortic coarctation. These are the conditions you do not need to use vascular surgery: Patients often have difficulty distinguishing what department to go to for some symptoms, and sometimes need the assistance of a doctor to determine, if you can not distinguish, you can ask a vascular surgeon to help identify, but some diseases do not necessarily need to see vascular surgery, so as not to delay the diagnosis and treatment. Immune vasculitis: Some vasculitis involves small blood vessels, which is a manifestation of immune disease in the microcirculatory system, so it is recommended that you see a rheumatologist. For hemangiomas of special sites, such as intracranial or spinal cord hemangiomas, hemangiomas of the liver, and intravertebral hemangiomas, we recommend that you consult the appropriate department, such as neurosurgery, hepatic surgery, or orthopedics.
