症例は生後5 時間の女児で,子宮内胎児発育遅延のため在胎32 週1 日に帝王切開で出生した極低出生体重児である。出生時に左前胸部に血管腫を,心臓エコー検査にて動脈管開存症,心室中隔欠損症を認めた。日齢1 より経管栄養を開始したところ高アンモニア血症を認め,同時期より左前胸部の血管腫が徐々に増大した。これらのことから門脈体循環短絡の存在を疑い,腹部エコー,腹部造影CT にて門脈低形成・静脈管開存による門脈体循環短絡との診断に至った。また,マス・スクリーニング検査にて高ガラクトース血症を認めた。経過中,心不全の増悪や高アンモニア血症を繰り返し,治療に難渋した。新生児で皮膚血管腫,高アンモニア血症,高ガラクトース血症を認めた場合は,門脈異常症,門脈体循環短絡の存在の可能性があり注意が必要である。 |

A female infant was born at 32 weeks and 1 day of gestation by Caesarean section because of the intrauterine growth
retardation. She had a hemangioma on the left anterior chest at birth. Echocardiography revealed the patent ductus
arteriosus and ventricular septal defect. Hyperammonemia was observed after the tube feeding since the 1 day of age. A
hemangioma of the left anterior chest became enlarged gradually at the same time. Abdominal echo and computed
tomography(CT)demonstrated the shunt circulation from portal vein, suggesting short-circuit due to patent ductus
portosystemic venous with portal vein hypoplasia. A mass screening examination revealed the galactosemia. Repeated
exacerbation of heart failure and hyperammonemia were refractory and difficult to control. The portosystemic shunt and
portal vein anomalies may be considered in a case with a skin hemangioma accompanied by the hyperammonemia, and
galactosemia in the newborns. |
