SURGERY FOR VASCULAR DISORDERS:
There are many causes of vascular problems. They can be classified into 5 groups:
Traumatic
Compressive
Occlusive
Tumors/malformations
Vasospastic (spasm of the artery, which reduces its diameter and thus its blood flow).
Vascular problems may occur more commonly in individuals with certain diseases such as diabetes, hypertension, or kidney failure, or in dialysis patients. Occupational exposure (vibrating tools, cold) can be a factor, and smoking also can aggravate and cause vascular disease.
