Utilizing flat-panel detector parenchymal blood volume imaging (FD-PBV) for quantitative kidney perfusion analysis during the process of percutaneous transluminal renal angioplasty (PTRA): A case report.

ABSTRACT:

Rationale

Traditional digital subtraction angiography (DSA) provides lumen morphology of renal artery as indicators for vascular patency in patients with renal artery stenosis (RAS). It, however, lacks hemodynamic information toward target kidney. To solve this shortcoming, a novel technique, flat-panel detector parenchymal blood volume imaging (FD-PBV), is introduced, which is able to evaluate hemodynamic changes of target kidney intraoperatively.

Patients concerns

A 77-year-old female presented with hypertension, intermittent dizziness, nausea, and fatigue.

Diagnoses

Ninety-nine percent stenosis of left RAS was found.

Interventions

Percutaneous transluminal renal angioplasty was performed, along with FD-PBV acquisition protocol.

Outcomes

Her symptoms r
