Acute cerebral infarction is extremely important to reduce the occurrence of hemiplegia if it is detected in time and treated with timely intracatheter thrombolysis. Cerebral artery stenosis is one of the main causes of cerebral infarction. Cerebral artery stenting for cerebral artery stenosis is an efficient and minimally invasive method to prevent ischemic stroke and improve function. Cerebral aneurysms are a major cause of cerebral hemorrhage, and endoluminal embolization treatment can lead to the cure of more than 80% of intracranial aneurysms. Interventional treatment is the method of choice when cerebral arteriovenous malformations are located in important functional areas of the brain or are inoperable at depth. Arterial occlusion of the extremities can lead to ischemic necrosis of the limbs, even requiring amputation, with a high rate of disability. Interventional treatment achieves the goal by opening the narrowed or occluded blood vessels, allowing patients to avoid amputation or reduce the scope of amputation. Diabetic foot is actually also the result of poor blood supply to the lower limbs caused by stenosis or occlusion of blood vessels, which further develops into ulceration and necrosis. Since open wounds in diabetic patients do not heal easily, treatment is difficult. Interventional minimally invasive treatment just overcomes the above difficulties, controls the degree of necrosis and infection in the lower limbs, and avoids extensive amputation. In addition to causing intractable hypertension, renal artery stenosis also leads to ischemic nephropathy and eventually renal insufficiency, the incidence of which is increasing year by year with a trend toward younger patients. Therefore, it is recommended that patients with unexplained intractable hypertension undergo CT or MRI examination to exclude renal artery stenosis. Deep vein thrombosis of the lower extremities causes swelling of the lower extremities. If high-dose thrombolytic therapy is given without knowing the extent of the thrombus, it is highly likely to cause thrombus dislodgement causing pulmonary embolism. Many unexplained deaths may be pulmonary embolism. Bleeding after trauma can be cured and recovered by finding the bleeding point through angiography (DSA) and embolizing the bleeding artery. Congenital vascular disease is a common pediatric condition that occurs at birth or shortly after birth as bright red or purplish neoplasms of varying sizes on the face and extremities. Treatment and consequences vary between vascular lesions. The preferred treatment for giant hemangiomas or vascular malformations is intravascular embolization or local injection sclerotherapy. What tests are needed for vascular disease? Color ultrasound can be used as a preliminary examination, CTA and MRA can provide a more detailed picture of the vasculature, and the most accurate is digital subtraction angiography (DSA).
