Vascular surgery is responsible for diseases that occur in the blood vessels of the circulatory system throughout the body except the heart, such as arteriosclerotic stenosis and occlusion, arterial dilatation diseases such as aneurysms or clips, 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. 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 arteriosclerosis occlusion of the lower limbs or diabetic foot, and prompt medical attention should be sought 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: Pulsating masses can be felt in the neck, limbs or abdomen, and the frequency of pulsation is similar to the heartbeat, suggesting the possible existence of an aneurysm, which may even rupture and endanger life if left untreated. Discovery of “arterial plaque”: Vascular “plaque” is found through ultrasound examination during physical examination. A small plaque dislodged may cause organ infarction and should not be taken lightly. “Small stroke” and “stroke”: Sudden onset of symptoms such as blurred eye vision, upper or lower extremity movement disorders, aphasia, crooked mouth and feet, etc., 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. Venous thrombosis: Ultrasound examination reveals venous thrombosis of the limb should be promptly seen in vascular surgery to avoid dislodging of the thrombus down the blood stream to the pulmonary artery and fatal pulmonary embolism, and venous thrombosis can also leave incurable sequelae if not treated in time. Patients often find it difficult to distinguish between some symptoms and what department they should go to, sometimes they need a doctor’s help to determine, if you can’t 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 diagnosis and treatment. 1.Special site hemangioma: such as intracranial or spinal cord hemangioma, liver hemangioma, intravertebral hemangioma, we recommend you to go to the appropriate department such as neurosurgery, liver surgery or orthopedics. 2.Immune vasculitis: some vasculitis involves small blood vessels, which is a manifestation of immune disease in the microcirculatory system, so we suggest you to go to rheumatology and immunology department for consultation.
