Placement of a Continuous Stellate Ganglion Block for Treatment of Refractory Ventricular Fibrillation in the Setting of Known Prinzmetal Angina During Pregnancy: A Case Report.

A patient with a history of Prinzmetal angina, refractory ventricular fibrillation, cardiac arrest with an implantable cardioverter-defibrillator, and obesity presented to the emergency department at 17 weeks gestational age with a chief complaint of angina and multiple episodes of defibrillation. A T3/4 thoracic epidural was placed to assess the effectiveness of a partial chemical sympathectomy in alleviating symptoms of angina as well as decreasing the amount of defibrillation episodes. Once this proved to be beneficial in accomplishing both of these goals, a more specific approach was designed. A continuous stellate ganglion block was then placed controlling both her angina and preventing further episodes of defibrillation long enough for her pregnancy to progress beyond 24 weeks gestational age.
