Why the study?

Long-term prognosis after TEVAR for Stanford type B aortic dissection remains critically dependent on sustained blood pressure control, with refractory hypertension perpetuating disease progression.

Key Points

Evaluate the clinical rationale and feasibility of combining thoracic endovascular aortic repair with renal denervation to treat type B aortic dissection complicated by refractory hypertension.
Evaluated a case report detailing a single-stage intervention integrating thoracic endovascular aortic repair with bilateral renal denervation.
Assessed anatomical risk stratification using the Nagamine classification for renal artery involvement alongside clinical trial evidence for catheter-based denervation.
Bilateral renal denervation was completed without vascular complications in complex anatomy exhibiting mixed true- and false-lumen perfusion (Nagamine subtype III-a).
Addressing sympathetic drive and the renin-angiotensin-aldosterone system simultaneously disrupts the cycle of severe hypertension, wall stress, and false-lumen pressurization.

Stanford type B aortic dissection (TBAD)

I

Intervention / Comparator

TEVAR with bilateral renal denervation (RDN)

Limitations

Whether bilateral RDN was truly necessary remains an open question.
Uncertain whether the independent antihypertensive contribution of RDN can be separated from the improvement following TEVAR itself.
A staged approach might have been equally effective while reducing procedural duration, contrast exposure, and radiofrequency manipulation.
