Long-Term Blood Pressure Control Effect of Celiac Plexus Block with Botulinum Toxin.

Celiac plexus block (CPB) is one of the main treatment options for patients resistant to conventional antihypertensive drugs. We present a case of resistant hypertension (RHTN) that was treated with CPB using botulinum toxin. An 18-year-old male patient with RHTN, who suffered from persistent hypertension even after combination therapy and a renal denervation procedure, was referred to our pain center for CPB. CPB using botulinum toxin following the use of only local anesthetics resulted in control of systolic blood pressure (BP) at ~150 mmHg for at least three months.
