Endovascular therapy for transplant renal artery stenosis based on anatomical foundations and three-dimensional digital subtraction angiography: A retrospective, single-center study

ObjectiveEndovascular recanalization is the preferred treatment for peripheral vascular diseases. This study evaluated the short-term outcomes of endovascular therapy for transplant renal artery stenosis (TRAS) administered based on anatomical foundations and three-dimensional digital subtraction angiography (3D-DSA).MethodsPatients with TRAS treated with endovascular therapy at a single center between October 2022 and October 2023 were retrospectively analyzed. The primary endpoint was the 12-month primary patency rate, defined as uninterrupted vessel patency without reintervention. Secondary endpoints included secondary patency rate (patency maintained after reintervention), blood pressure, and serum creatinine (Scr) levels.ResultsThe study included 23 patients (mean age: 41.1 ± 11.5 years; 9 females). All patients underwent successful plain old balloon angioplasty (POBA); 13 underwent POBA plus balloon-expandable bare-metal stent (BMS) deployment. The procedure-related complication rate was 13.04%. Technical success was defined as
