Why is the internal mammary artery used for grafts?
The internal mammary artery (IMA) grafts have been associated with long-term patency and improved survival as compared to saphenous vein grafts (SVGs). Early failure of IMA is attributed to poor surgical technique and less with thrombosis.
Does everyone have intramammary lymph nodes?
Normal intramammary lymph nodes are no exception and can vary in size, but they are generally smaller than lymph nodes encountered in the axilla (armpit).

The internal thoracic vein arises from the superior epigastric vein. It forms venae comitantes to the internal thoracic artery and accompanies it in its course, before uniting to form a single vein 1. After uniting, each internal thoracic vein drains into its respective brachiocephalic vein 2.
What are the tributaries of internal thoracic vein?
