Embolization of the Major Aorto-Pulmonary Collateral Artery in Tetralogy of Fallot: Report of One Case

以動脈栓塞法堵塞主動脈-肺動脈側支血管:一病例報告

摘要


發紺性先天性心臓病的病人常衍生出一些主動脈肺動脈側支血管,在開刀矯治同時必須將這些側支血管結紮,以避免術後血流量過多,反而引起心衰竭。但是有些側支血管位在外科手術所不能及或不易操作之深部,若勉強行之可能延誤開刀時間甚至造成危險。本文報告利用動脈栓塞法成功地阻絕深部主動脈且動脈側支血管,縮短了隨後心手術的時間並降低其危險性。 病人爲一5歲3個月大男童,於嬰兒期即經診斷患有法洛氏四合症,並曾經歷二次鎖骨下動脈一肺動脈分流術。爲施行全矯治術,他於80年6月接受心導管檢查,結果發現一大側支血管由降主動脈分出供應右上部份肺葉。鑑於此血管太過後面深部,外科醫師進行心臓全矯治時恐不易結紮,因此於術前2個月施行動脈栓塞法將此側支血管堵塞;結果成效良好,病童並未出現發紺或其它不適。兩個月後病童接受心臓全矯治療。

A boy with tetralogy of Fallot diagnosed in infancy, presented for definitive correction at the age of 5 years and 3 months. He had undergone bilateral Blalock-Taussig shunts twice at 1 and 2 years of age, respectively. Cardiac catheterization and angiography prior to total correction revealed a major aorto-pulmonary collateral artery arising from the thoracic aorta and supplying the right upper lung. Embolization of the collateral artery with two platinum coils (via catheterization) was performed. The successful embolization exempted the patient from the risky ligation of the deeply located collateral artery.
