Unusual infra-clavicular venous circle - A case report

Currently, numerous invasive procedures are preferred in cephalic vein (CV) and axillary vein (AV) than other veins in the neck. Anatomical variations of these veins in the axilla and delto-pectoral region may result in failure and postoperative complications of the procedures. A thorough knowledge of possible variations of AV and CV may immensely contribute to the success of any such procedures where the veins are involved. We report the variations of the CV, tributaries of AV and median cubital vein. We observed a venous circle formed by the tributaries of AV in the infra-clavicular region, deep to the pectoral muscles. Cephalic vein joined proximal end of venous circle just before ending into AV. Further, duplication of the median cubital vein was observed.
