Abstract No. 500 Patterns of clinical history and angiography in hypothenar hammer syndrome: a case series

Abstract

needles were placed in complex IR cases using this new needle guidance technology: 9 liver or kidney ablations, 2 sacroplasties and 1 pleural based lesion biopsy. Needle 3D position was verified 37 times, with Stereo3D used 22 times and full CBCT used 15 times, and re-adjusted 16 times. 10 needle positions were verified with both Stereo3D and CBCT. Stereo3D reconstruction inaccuracy was 2.8mm (±6.3) in depth and 4.4mm (±3.4) off the center of the needle tract. For bone lesions the error was 2mm. Using Stereo3D reduced the procedure air kerma (Gy) and DAP (Gy.cm 2 ) by 27% and 35% on average. Conclusions: Using needle guidance tools enables to significantly reduce the radiation dose exposure to patients during complex interventional radiology procedures while ensuring accurate planning, guidance and position assessment.
