Upon the patient's arrival to the ER, he showed right hemiparesis with brachial predominance and dysphasia that was recovered after the IV administration of nimodipine, fluid therapy, and noradrenaline. Twenty-four hours after admission, one coronary arteriography was conducted followed by the adequate embolization of the aneurysm. During the test, the presence of significant vasospasm was confirmed and it was treated with the local infusion of 2<span class="elsevierStyleHsp" style=""></span>mg of nimodipine in both anterior cerebral arteries and left middle cerebral artery (MCA), and in the left pericallosal artery where 2 additional mg of nimodipine were instilled followed by one balloon angioplasty with good final angiographic results.

On the third day, the angiography was repeated with a new infusion of 8<span class="elsevierStyleHsp" style=""></span>mg of nimodipine but this time with partial results. The computed tomography scan performed revealed the presence of one small left frontal ischemic lesion. Due to the lack of clinical improvement (right arm paralysis and dysphasia), the Pain Treatment Unit was contacted to perform one left cervical stellate ganglion block procedure that was conducted 4 days after admission and under X-ray imaging (<a class="elsevierStyleCrossRef" href="#fig0005">Fig. 1</a>). One bolus of 10<span class="elsevierStyleHsp" style=""></span>ml of bupivacaine at 0.5% was administered and one IV cannula was inserted for the repeated administration of the drug every 12<span class="elsevierStyleHsp" style=""></span>h. Thirty minutes after the block, the right arm partially recovered its strength and the naming of objects improved as well. At that time, the TCD confirmed that mean velocity was reduced 10% in the left MCA (<a class="elsevierStyleCrossRef" href="#fig0010">Fig. 2</a>A and B) and that it gradually decreased over the following hours. After 3 days on bupivacaine (6 doses), the patient showed minimum brachial claudication, and no speech disorder.

There are several factors associated with the appearance of vasospasm. Among the most important ones we find the volume of blood flow in the subarachnoid space (Fisher grading scale), the neurological status on admission (the Hunt–Hess scale or WFNS scales) and the size and location of the aneurysm.<a class="elsevierStyleCrossRef" href="#bib0070"><span class="elsevierStyleSup">4</span></a></p><p id="par0025" class="elsevierStylePara elsevierViewall">According to the last recommendations established by the AHA,<a class="elsevierStyleCrossRef" href="#bib0075"><span class="elsevierStyleSup">5</span></a> in the presence of focal symptoms indicative of vasospasm, treatment should be based on inducing hypertension (class I, level B) and using intravascular techniques through cerebral angioplasty and/or selective infusion of intraarterial vasodilators (class IIIa, level B). No study recommends the use of any other therapies with enough level of evidence. In cases of vasospasm refractory to these treatments, several different options have been suggested such as the intrathecal administration of vasodilating drugs, the use of a continuous perfusion of intraarterial nimodipine or the stellate ganglion block.<a class="elsevierStyleCrossRefs" href="#bib0080"><span class="elsevierStyleSup">6,7</span></a></p><p id="par0030" class="elsevierStylePara elsevierViewall">The stellate ganglion regulates the sympathetic tone of head, neck, and upper extremities; its anesthetic block is indicated to control neuropathic pain, in cases of phantom limb pain, hyperhidrosis or vascular failure of upper extremities such as Raynaud's phenomenon due to its vasodilating effect.<a class="elsevierStyleCrossRef" href="#bib0090"><span class="elsevierStyleSup">8</span></a> The stellate ganglion block has been used successfully for the management of refractory vasospasm in isolated cases or series of cases; these show that, after the stellate ganglion block using a local anesthetic (usually bupivacaine), there is clinical improvement with partial or complete recovery of neurologic deficit since there is more blood flow coming to the cerebral arteries that are ipsilateral to the block being this effect more significant in younger patients.<a class="elsevierStyleCrossRefs" href="#bib0095"><span class="elsevierStyleSup">9,10</span></a></p><p id="par0035" class="elsevierStylePara elsevierViewall">In order to perform this technique an adequate anatomical knowledge is essential.
