A study of the arrangement of the superficial veins of the cubital fossa was made on 300 students and staff of the Military Medical College and the AlMustansiriya College of Medicine. Six types of variations of arrangement of the veins were found, two of which have not been mentioned before. The commonest type was that the median vein of the forearm divides in the cubital fossa into 2 veins, one of which joins the basilic vein, and the other the cephalic vein, although in a few cases this joining (or arrangement), occurred above the cubital fossa. The arrangements which have not been mentioned before were that the communication between basilic and cephalic veins was through a horizontal venous connection between 1 of the tributaries of these 2 veins and the basilic vein, and that the median vein of the forearm divides into median cephalic and median basilic, and a vein from the front of the forearm drains into the median basilic vein.

Structures passing through the triangular space of the human upper limb have been studied in 50 upper limbs from 25 cadavers. In all the specimens used in this study, a branch of the circumflex scapular artery with an accompanying vein was found to pass through this space.
