Diseases of arteries, veins, and lymphatic vessels throughout the body (except for those in the heart and brain) fall under the scope of vascular surgery treatment. What diseases need to be seen in vascular surgery? 1.Arterial diseases: acute arterial embolism, acute arterial thrombosis, lower extremity atherosclerosis occlusion, carotid stenosis and occlusion, carotid body aneurysm, carotid aneurysm, thoracoabdominal aortic aneurysm, thoracoabdominal aortic coarctation aneurysm, abdominal aortic aneurysm, multiple aortitis, pulselessness, renal artery stenosis, Raynaud’s syndrome, etc.; 2.Venous diseases: lower extremity primary deep vein valve insufficiency, deep vein thrombosis sequelae, acute deep vein thrombosis, Bou-ga syndrome, inferior vena cava obstruction syndrome, portal hypertension syndrome, etc.; 3, combined arteriovenous diseases: vaso-occlusive vasculitis, thoracic outlet syndrome, N vascular trapping syndrome, etc.; congenital vascular diseases; 4, congenital arteriovenous fistula, congenital vascular malformation, congenital limb venous malformation-skin hemangioma-osteo-soft tissue hypertrophy syndrome ( KTS), congenital deep vein anomaly of the lower extremity, congenital deep vein valve hypoplasia of the lower extremity, hemangioma, etc.; 5. Vascular injury: arterial injury, venous injury, pseudoaneurysm, traumatic aneurysm, etc. How to see that you have vascular disease? 1, unexplained or after surgery or long-term bed rest in a relatively short period of time appeared on one or both lower limbs swelling, to be alert to deep vein thrombosis; 2, patients with heart disease atrial fibrillation or ventricular wall tumor, etc. suddenly appear limbs cool, numb, pain, pale, ischemia, or suddenly appear severe abdominal pain, nausea, vomiting, abdominal distension, etc., is likely to appear arterial embolism; 3, the elderly, diabetic patients gradually appear limb pulse weak, No pulse, calf cramps and pain after walking a short distance, relieved after rest, recurring after walking; some directly manifested as cold, numb, painful limbs, pain can cause sleepless nights, and then serious limbs will appear blue, black necrosis, likely to have atherosclerosis occlusive disease or diabetic atherosclerosis limb ischemia; 4, young people, especially male smokers appear limb phlebitis, weak pulse, no pulse or cold, numb, painful, 5, young women with weak pulse, no pulse, dizziness, hypertension, cataracts may have aortitis (pulseless disease); 6, abdomen, neck or limbs to feel the throbbing mass may be aneurysms or arteriovenous fistula; 7, the abdominal wall varicose veins starting from the root of the thigh combined with cirrhosis, ascites patients to exclude Bu-plus syndrome; 8, varicose veins, some easy to see Vascular protrusions and blood-containing masses may be vascular disease; 9. Patients with small strokes should look at the carotid artery for stenosis.
