We read with great interest the recently published article about cervical sympathetic block.1 The authors state that a cervical anesthetic injection performed at the level of the middle cervical ganglion, or C6 level, will inhibit both superior preganglionic fibers and the stellate ganglion at the C7 level by spreading both upwards and downwards. At this level, they considered that both the preganglionic fibers that enervate the anterior circulation and the postganglionic fibers that enervate the posterior circulation would be blocked. Additionally, the authors have stated that there is evidence that nerve blocks performed with ultrasound guidance are superior in terms of effectiveness and have fewer reported minor complications.2 The aim of this letter is to describe a new sympathetic chain block approach in the supraclavicular fossa and explain its advantages.
