About this trial
The aim of this pilot study is to assess the efficacy of amiloride in reducing wall enhancement in vertebrobasilar dolichoectasia(VBD) on high-resolution magnetic resonance vessel wall imaging(HR-VWI) via anti-inflammatory mechanisms, clarify the efficacy of amiloride in delaying the progression of VBD, evaluate the safety of amiloride in the treatment of VBD.

Treatments tested in this trial
Amiloride hydrochlorothiazide
DrugAmiloride, a potassium-sparing diuretic, also an mTORC2 inhibitor, has been widely utilized in clinical settings. It can be employed as an adjunctive agent for hypertension management and has been investigated in completed clinical trials targeting resistant hypertension.
Treatment groups
Trial outcomes
Primary outcomes
Longitudinal changes of CAWE on 5T HR-VWI in VBD following 3 and 6 months of amiloride treatment.
Using 5T HR-VWI, we quantify longitudinal changes of vascular CAWE (3D circumferential arterial wall enhancement: mean signal intensity in T1+Gd images) at 3 and 6 months following initiation of amiloride therapy. The primary objective of this study is to determine whether amiloride exerts an anti-inflammatory effect on the diseased vertebrobasilar arterial wall in patients with VBD.
Longitudinal changes of SAWE on 5T HR-VWI VBD following 3 and 6 months of amiloride treatment.
Using 5T HR-VWI, we quantify longitudinal changes of vascular SAWE (specific contrast uptake arterial wall enhancement: the difference in mean signal intensity between T1 and T1+Gd) at 3 and 6 months following initiation of amiloride therapy. The primary objective of this study is to determine whether amiloride exerts an anti-inflammatory effect on the diseased vertebrobasilar arterial wall in patients with VBD.
Longitudinal changes of FAWE in VBD on 5T HR-VWI 3 and 6 months of amiloride treatment.
Using 5T HR-VWI, we quantify longitudinal changes of vascular FAWE (focal arterial wall enhancement: areas of the diseased artery with increased AWE) at 3 and 6 months following initiation of amiloride therapy. The primary objective of this study is to determine whether amiloride exerts an anti-inflammatory effect on the diseased vertebrobasilar arterial wall in patients with VBD.
Longitudinal changes of WEVR on 5T HR-VWI in VBD following 3 and 6 months of amiloride treatment.
Using 5T HR-VWI, we quantify longitudinal changes of vascular WEVR (3D arterial wall enhancement volume rate) at 3 and 6 months following initiation of amiloride therapy. The primary objective of this study is to determine whether amiloride exerts an anti-inflammatory effect on the diseased vertebrobasilar arterial wall in patients with VBD.
Secondary outcomes
Longitudinal changes of CAWE on 5T HR-VWI in VBD following 12 months of amiloride treatment.
Using 5T HR-VWI, we quantify longitudinal changes of vascular CAWE (3D circumferential arterial wall enhancement: mean signal intensity in T1+Gd images) at 12 months following initiation of amiloride therapy. The primary objective of this study is to determine whether amiloride exerts an anti-inflammatory effect on the diseased vertebrobasilar arterial wall in patients with VBD.
