ABSTRACT
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 gradeâ 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.
