Final answer:
Varicose veins most often occur in saphenous veins and are caused by incompetent valves from damage or venous dilation. They are commonly found in the lower limbs and can be painful and itchy. Treatment options include wearing support hose, elevating the feet and legs, laser surgery, interventional radiologic procedures, or conventional surgery.
Step-by-step explanation:
Varicose veins most often occur in the saphenous veins and are caused by incompetent valves from damage or venous dilation, AV fistula, and congenital venous malformations. Varicose veins are commonly found in the lower limbs, especially in the superficial veins of the legs.
This disorder arises when defective valves allow blood to accumulate within the veins, causing them to distend, twist, and become visible on the surface of the integument. Varicose veins may occur in both sexes, but are more common in women and are often related to pregnancy. They are more than simple cosmetic blemishes, as they can be painful and sometimes itchy or throbbing. Without treatment, they tend to worsen over time. Support hose and elevating the feet and legs whenever possible may help alleviate this condition. Laser surgery, interventional radiologic procedures, or conventional surgery may be necessary to treat varicose veins depending on the severity of the case.
