Understanding thrombophlebitis
When someone has thrombophlebitis, blood clots within the vein and this irritates the vein wall. A thrombus or blood clot is formed in the vein and as part of the healing process, the vein wall becomes inflamed. Together these factors cause the vein to become hard, tender, red and hot. Professor Mark Whiteley tells us exactly what thrombophlebitis is and the different types that exist.
