A case of the bilateral superficial brachial arteries which continued to the radial arteries in the forearms.

During the dissection course of Kobe University School of Medicine, we found the bilateral superficial brachial arteries that continued to the radial arteries in a 90-years-old female cadaver. Each superficial brachial artery is classified Arteria brachialis superficialis lateralis inferior. This artery directly continued to the radial artery in the forearms on each side. Anomalous branching patterns of the (proper) brachial artery in this case belong to the type 7 of Adachi's classification. The incidence and embryological aspects of this anomalous arterial branching are discussed.
