Detailed explanation-1: -The stellate ganglion is a collection of sympathetic nerves found anterior to the neck of the first rib. It may occasionally extend to being anterior to the transverse process of the C7 cervical vertebra.
Detailed explanation-2: -What is Stellate Ganglion Block? The stellate ganglion block (SGB) is a procedure in which an injection of a long-acting local anesthetic, using ultrasound or fluoroscopic guidance, is made in the right side of the neck around the main nerve that controls the “fight or flight” response (the sympathetic nervous system).
Detailed explanation-3: -These results suggest that the left stellate ganglion contributes more sympathetic tone to the myocardium than the right. This explains why most human studies use unilateral left SGB for treatment of ventricular arrhythmias [7••, 13••].
Detailed explanation-4: -A stellate ganglion block (sympathetic block) is an injection of local anesthetic into the front of the neck. It is typically used for pain located in the head, neck, chest or arm that is caused by: Sympathetically maintained pain (reflex sympathetic dystrophy)
