【背景】動脈管開存症(PDA)に対するカテーテル治療は,使用するデバイスが増えたことで様々な形態やサイズにも対応できるようになった.2020年に保険収載されたAmplatzer® Piccolo Occluder(Piccolo)は,製造中止となったFlipper® PDA Closure Detachable Coil(Flipper PDA coil)に変わる役割も期待される.

【対象と方法】2020年10月から2022年9月までの2年間に当院でPiccolo留置を行なった22例を対象とした.年齢,体重,PDAサイズ・形態について,Piccolo導入以前の2017年1月から2019年12月までの3年間にFlipper PDA coilを留置した23例と比較した.


【結論】Piccoloは比較的細い(主に2 mm以下)PDAに安全に留置することができ,Flipper PDA Coilに代わり,その役割を十分果たすと考える.

【Background】 Catheter intervention for patent ductus arteriosus (PDA) has become possible to close various shapes and sizes of PDA due to the increased number of available devices. The Amplatzer® Piccolo Occluder (Piccolo) is expected to replace the discontinued Flipper® PDA Closure Detachable Coil (Flipper PDA Coil).

【Subjects and Methods】 Twenty-two patients who underwent Piccolo implantation at our hospital from October 2020 to September 2022 were included. Age, body weight, PDA size, and morphology were compared with twenty-three patients who had a Flipper PDA Coil implanted from January 2017 to December 2019.

【Results】 There were no significant differences in age, body weight, PDA size and morphology between the two devices, suggesting that they were used in similar cases. No complications or residual shunt were observed with Piccolo implantation.

【Conclusion】 Piccolo can be safely implanted in small PDA (less than 2 mm) and may replace the Flipper PDA Coil.
