Peripheral vascular lesions include lesions such as peripheral vascular stenosis, occlusions, and pseudoaneurysms. Atherosclerosis is a common cause of symptomatic vascular stenosis. The causative factors are similar to coronary artery disease and include factors such as by family history, smoking, diabetes, hypertension, age, and lack of exercise. Clinical symptoms include pain in the extremities, chills, intermittent claudication, ulceration, and gangrene. In addition multiple aortitis can also cause peripheral vascular stenosis and occlusion, often involving the subclavian, renal, and iliac arteries causing the corresponding clinical symptoms. Pseudoaneurysms are often associated with trauma and can cause local masses and bleeding. Interventional endovascular therapy is a method of treating vascular lesions by inserting a specially designed catheter into the diseased vessel under the guidance of X-ray television (DSA) and performing vasodilatation and shaping or implanting a vascular stent or special embolic material. Advantages: Angioplasty for peripheral vascular stenosis or occlusive lesions has become the first-line treatment option for peripheral vascular stenosis and occlusion, and endovascular angioplasty is clinically and patient-acceptable because of its small trauma, precise efficacy, high safety, few complications, rapid recovery, short hospital stay, and ease of repeat treatment. For patients with diabetic foot requiring amputation, angioplasty can often improve the amputation plane. For patients with brain theft caused by subclavian artery stenosis and hypertension caused by renal artery stenosis, angioplasty can effectively improve the clinical situation. Clinical Applications: Angioplasty is commonly used to treat segmental stenosis or occlusion of the peripheral vasculature and stenosis or occlusion of the renal arteries. Vascular stents may be implanted as appropriate in patients with poor vasodilatation results. Interventional treatment of peripheral vascular pseudoaneurysms can be treated by occlusion of the artery or lumen supplying the pseudoaneurysm. At present, dozens of peripheral vascular lesions have been treated with balloon dilation and angioplasty (PTA) and stent implantation in our hospital, and good clinical results have been achieved.
