The posterior humeral circumflex artery (arteria circumflexa humeri posterior, PHCA) stems from the AA at the distal border of the subscapularis (musculus subscapularis) from the proximal segment of the infrapectoral (last, third) part of the AA and runs dorsally into the quadrangular space (foramen humerotrici-pitale, spatium axillare laterale) together with the axillary nerve (nervus axillaris).

Such variant can be denominated as the subtendinous posterior humeral circumflex artery (arteria circumflexa humeri posterior subtendinea), conjoint with the profundocircumflex trunk (truncus profundocircumflexus) to describe all the peculiarities and to avoid any possible misnomers.
