Parallel intravascular lithotripsy catheters technique for calcified atherosclerotic abdominal aortic stenosis

Blog Article

BACKGROUND: Calcified atherosclerotic abdominal aortic stenosis is a rare and challenging condition, with heavily annular calcification limiting the effectiveness of traditional endovascular treatments.METHODS: A 66-year-old female with severe abdominal aortic stenosis underwent treatment using a parallel intravascular lithotripsy (IVL) catheter technique.Bilateral femoral access and arterial embolization were followed by parallel IVL angioplasty, stent implantation, and postdilation.A swine model was used 5 Piece Queen Platform Bedroom to assess vascular injury after parallel IVL.RESULTS: The parallel IVL technique significantly relieved the stenosis without complications, as confirmed by angiography.

In the swine 4 Piece Large Entertainment Wall model, histological analysis showed no significant vascular injury, except for expected intimal disruption and elastic lamina stretching.CONCLUSION: Parallel IVL catheter angioplasty is a feasible and safe approach for heavily calcified abdominal aortic stenosis, warranting further studies to validate its long-term outcomes.
