Stellate Ganglion Block (cervical sympathetic chain block) with ultrasound guidance; in-plane or out of plane?

Assuming one starts at C6 or C7, Seems to me using an out of plane approach makes a lot of sense, for the following reasons: 1. easier to avoid vessels 2. If standing at head, and needle trajectory is from cranial to caudal trajectory, could push meds further caudal to stellate ganglion. thoughts and preferences?
