Percutaneous endovascular tissue sampling of endoluminal tumors using directional atherectomy

ConclusionPreliminary results in a limited number of patients proved directional atherectomy beneficial as a safe and feasible technique for endoluminal tissue sampling of vascular masses. Additional large-scale studies are necessary and worthy for further evaluation in clinical practice.Key Points• Endovascular masses pose a challenge to appropriate clinical management.• Off-label directional atherectomy proved to be a safe and feasible technique for endoluminal tissue sampling of vascular masses. Furthermore, directional atherectomy was superior to aspiration or forceps biopsy in our small study cohort.• Directional atherectomy may represent the last or only option for tissue probing as a prerequisite for further treatment decisions.
