OBJECTIVE: Our objective was to describe the technique and outcome of CT-guided injection of botulinum toxin into the diaphragmatic crus in a patient with hypertension caused by left diaphragmatic crus compression of the left renal artery. CONCLUSION: After the procedure, the patient's hypertension disappeared. We propose this technique, which directly targets inhibition of overactivity of the diaphragmatic crus, for treatment of hypertension caused by diaphragmatic compression of the renal artery as an alternative to surgery and renal artery stenting.
