The angular vein is a blood vessel in the head. It is a branch of the facial vein ( vena facialis ). The angular vein runs in the corner of the eyelid on the side of the nose , on the side of the artery of the same name and can shimmer through the skin in thin-skinned people.
The blood vessel is of clinical importance in the development of sinus thrombosis , as it is connected to the superior ophthalmic vein . During surgical interventions on the eyelid it must be spared, as its injury leads to bleeding that is difficult to stop .
