Appears smaller, because the vein contracts and there is no blood flowing through it. This is what a varicose vein looks like after it is removed by phlebectomy. The needle points to the ballooning of the vein (dilatation). This commonly occurs just after the valve, which is not functioning properly. The bulges you see under the skin, in many instances are the dilated areas the needle is pointing to.
