第 3 題
男嬰出生時立即發生呼吸窘迫及發紺症狀，身體診察發現腹部扁平、最強心尖搏動點（point of maximal impulse）在右胸，下列何者為最可能的診斷？
- A 先天性橫膈膜疝氣（congenital diaphragmatic hernia）
- B 食道閉鎖氣管食道瘻管（esophageal atresia with tracheoesophageal fistula）
- C 後鼻孔閉鎖（choanal atresia）
- D 胃扭轉（gastric volvulus）
思路引導 VIP
請從臨床解剖學的角度思考：若新生兒出現「腹部扁平（scaphoid abdomen）」且心臟搏動點發生位移，這暗示原本應位於腹腔的臟器可能經由發育缺陷處進入了哪一個解剖空間，進而壓迫肺部並造成縱隔腔（mediastinum）的機械性偏移？
