Varicose veins of the arm are divided into two cases, which are treated as follows: 1. Primary: The majority of patients have primary varicose veins, which are caused by venous valve insufficiency and poor venous return, resulting in obvious, even tortuous and dilated arm vessels, which do not require special treatment because varicose veins of the arm do not cause serious consequences. 2. Secondary: Secondary varicose veins are Due to the blockage of deep veins or other veins, it leads to the tortuous and dilated superficial veins in the arm, which compensates for the venous reflux. In case of deep vein blockage or thrombosis, regular and systematic treatment is needed, and if necessary, vascular surgery is required to release the deep vein stenosis or even thrombosis. Therefore, the majority of varicose veins in the arms that appear in clinical practice are primary varicose veins, which can be observed regularly and do not require special treatment. If the varicose veins are secondary, they must be treated systematically in a specialized vascular surgery department.
