Abstract 16184: Impact of Aortorenal Morphology in Renal Artery Intervention: Procedural Significance of Abdominal Aorta Tortuosity and Renal Artery Derivation
Objectives: There has been limited information of classification of aortorenal morphology and its impact on renal artery interventional procedures.
Methods: This study included a total of 142 consecutive renal artery stenting procedures performed for de novo atherosclerotic renal artery stenosis. All procedures were implemented via a transfemoral approach without distal protection. We classified aortorenal morphology into the 3 types on the basis of the relationship between abdominal aorta tortuosity and renal artery derivation (Figure1 and Table). We also evaluated the technical success rate, the procedure time between the initiation of guide catheter engagement technique and the completion angiography, and any adverse events.
Results: Type1 was observed in 91 cases, type2 in 30 and type 3 in 21, respectively. The procedure time significantly (P<0.001) differed among the 3 groups (Figure2), although all cases were successfully treated. No technical complications, major in-hospital cardiovascular events, or deaths occurred.
Conclusions: The complex of aortorenal morphology was significantly associated with the procedure time. The present novel classification of aortorenal morphology could be of help for stratifying the degree of difficulty in renal artery intervention including stenting and ablation procedures.
