Abstract
Background: Now a days, Internal thoracic artery (ItA) is being widely used in coronary artery bypass grafting(CABG) and in breast reconstructive surgeries. In addition, the area around its origin is also used for subclavianvein catheterization and introducing a pacemaker.Aim: Aim of the study was to know the normal and variant anatomy of internal thoracic artery in Indian subjectsin order to provide useful data to thoracic surgeons, so as to prevent iatrogenic complications in ItA dissections.Clinical applications related to variations were analysed.Material and Methods: 30 cadavers were dissected to see the mode of origin of internal thoracic artery, diameterat its origin and relation with phrenic nerve and thyrocervical trunk.Results: 55 arteries were showing normal origin and tend to arise opposite the root of thyrocervical trunk.Remaining 5 were arising in common with one or two branches of thyrocervical trunk. Average diameter at itsorigin was 2.8cm on left and 2.6cm on right. Relation with phrenic nerve was variable.Conclusion: During CABG surgery, Breast reconstructive surgery and various interventional procedures, it isimportant to know the variant pattern of ItA so as to avoid iatrogenic complications
