Key result
Percutaneous embolization of an iatrogenic high-flow fistula restores drug responsiveness in severe systolic hypertension.
Why the study?
Does closure of an iatrogenic high-flow fistula with percutaneous embolization improve drug-resistant severe systolic hypertension?
Does closure of an iatrogenic high-flow fistula with percutaneous embolization improve drug-resistant severe systolic hypertension?
Percutaneous embolization of an iatrogenic high-flow fistula can resolve severe, drug-resistant systolic hypertension.
Alerts clinicians to occult fistulas in resistant hypertension; leaves open whether closure warrants prospective evaluation.
In summary, long-term exposure to a large, iatrogenic highflow fistula caused very severe systolic hypertension to develop, which was resistant to standard treatment. Closure of the fistula with percutaneous embolization resulted into a marked improvement of the hypertension, which became responsive to drug treatment.

Maiolino et al. (2019) studied this question. Percutaneous embolization to close an iatrogenic high-flow fistula markedly improved severe, drug-resistant systolic hypertension, making it responsive to standard drug treatment.
