摘要

AIM:To determine which modification to a vascular puncture needle results in increased visualization during ultrasound(US)-guided vascular puncture.METHODS:We evaluated US images of a phantom made of degassed gelatin and each of the following four modified versions of a commercially available vascular puncture needle(18 G):re-cut needle,dimple needle,rough-surface needle(rough over the sections of needle located 3-6 mm from the tip),and a needle with four side holes(side holes covered by the sheath).An unmodified commercially available puncture needle was used as a control.Five interventional radiologists evaluated image quality according to the following classification grade:Ⅰ,invisible;Ⅱ,poor;Ⅲ,moderate;Ⅳ,good;Ⅴ,excellent.RESULTS:The highest score for needle visualization was obtained for the needle with four side holes.The re-cut needle scored the same as the control.Multiple comparisons were conducted using overall evaluation scores among the commercially available needle,dimple needle,rough-surface needle(3-6 mm),and the needle with four side holes.A significantly higher score was obtained for the needle with four side holes(P 【 0.05/6).CONCLUSION:The needle with four side holes was prominently visualized and gained a significantly higher score(compared with the other needles) in a phantom evaluation.
