The wall of a varix is notably thickened, so that when cutacross the vein gapes like a divided artery. The intima is thickenedand shows longitudinal strise. Sometimes it is atheromatous, or evencalcified. The thickening of the intima may be general, or especiallymarked at one part of the circumference of the vein (Fig. 165). Itprobably has an important influence in the production of Fig. 163.—A Varicose Vein.(Middlesex HospitalMuseum.) 572 DISEASES OF BLOOD-VESSELS.
