Endovascular Treatment of Renal Artery Dissection with a Goal of Sustained Blood Pressure Normalisation
Renal artery dissection calls for a precise interventional strategy aimed at restoring arterial integrity and achieving durable haemodynamic control. This protocol defines the procedural approach and the blood pressure outcome that marks treatment success.
Treatment Approach
Management is centred on an endovascular repair strategy carried out under local anesthesia, with stent placement in the renal artery selected according to the specific anatomy of the dissection.
The full procedural algorithm — including anticoagulation, stent type selection, and deployment criteria — is available in the complete protocol.
Clinical Target
The primary measure of success is cured hypertension, defined as a sustained systolic/diastolic blood pressure below 140/90 mmHg without the use of any antihypertensive medication.

- Endovascular repair was performed under local anesthesia.
- Heparin (100 units/kg) was intravenously administered.
- A covered stent or bare stent was advanced over the guidewire and deployed in the desired position.
- Covered stents were used only in the main trunk without involving the surrounding branches based on the length of the dissection.
- Otherwise, bare stents were selected.
- After endovascular treatment, cured hypertension was defined as a systolic/diastolic blood pressure of <140/90 mm Hg without the use of any antihypertensive drugs.
