Protruding blood vessels in the thighs should be referred to vascular surgery, which is the best place to consult for problems with all blood vessels in the body, except for those in the heart and brain. The protruding blood vessels in the thighs are more likely to be considered varicose veins, which appear on the surface of the body as tortuous and dilated blood vessels, sometimes accompanied by edema and changes in skin color, and should be seen by vascular surgery followed by ultrasound, which can determine the function of the lower extremity venous valves, including deep and superficial valves, and whether there is incompetence, and based on the results, determine the patient’s staging, and further treatment options.
