目的 探討動脈導管未閉(PDA)合并重度肺動脈高壓(PH)患者外科手術治療與介入封堵治療的適應證和治療效果。 方法 回顧分析1998年5月至2008年5月我科收治的30例PDA患者的臨床資料，其中男14例，女16例；年齡14～41歲，平均年齡25.8歲。18例行外科手術治療，12例行介入封堵治療。 結果 經外科手術和介入封堵治療患者術后即刻的肺動脈收縮壓(608±120 mm Hg vs. 100.2±14.2 mm Hg; 60.3±11.6 mm Hg vs. 108.4±17.6 mm Hg)和平均肺動脈壓(401±98 mm Hg vs. 76.1±11.3 mm Hg; 40.2±10.5 mm Hg vs. 79.5±13.6 mm Hg)均較術前明顯降低（Plt;0.05）。術后4例手術患者中有2例出現聲音嘶啞，2例殘余分流；介入封堵治療患者術后未出現明顯并發癥。隨訪29例，隨訪時間3個月~2年；1例失訪。隨訪期間患者無明顯胸悶、氣促等，超聲心動圖檢查大動脈水平未探及殘余分流，1例術前伴有心房顫動的患者在封堵術后2個月時猝死，死亡原因不明。28例患者術后90 d復查超聲心動圖提示：肺動脈收縮壓均較術前明顯降低（Plt;0.05），兩種治療方法的療效差異無統計學意義（Pgt;0.05）。 結論 介入封堵治療PDA合并重度PH的患者與外科手術治療相比較具有創傷小、風險小、并發癥少和恢復快等優點，尤其是介入封堵治療可行試驗性封堵，對鑒別動力性和阻力性PH具有不可替代的優越性。但一些特殊類型的PDA患者仍需外科手術治療。
Objective To investigate clinical outcomes of complete video-assisted thoracoscopic lobectomy and summarize our preliminary experience. Methods Clinical data of 60 consecutive patients who underwent complete video-assisted thoracoscopic lobectomy in General Hospital of Chengdu Military Command from March 2010 to August 2011 were retrospectively reviewed. There were 37 male patients and 23 female patients with their median age of 52.1 （17-77） years. There were 7 patients undergoing left upper lobectomy， 19 patients undergoing left lower lobectomy， 12 patients undergoing right upper lobectomy， 3 patients undergoing right middle lobectomy， 17 patients undergoing right lower lobectomy， and 2 patients undergoing combined right middle and lower lobectomy. Results The average operation time was 161 （50-270） minutes， average intra-operative blood loss was 310 （50-800） ml， average number of lymph node dissection was 13.4 （6-29）， average postoperative thoracic drainage was 950 （250-2 800） ml， average duration of thoracic drainage was 4.6 （3-11） days， average intensive care unit stay was 1.2 （1-3） days， and average postoperative hospital stay was 7.7（4-14） days. None of the patients had any severe postoperative complication. Fifty-two patients were followed up for 7 to 24 months， and 8 patients were lost during follow-up. During follow-up， 5 patients had lung cancer metastases， including 2 patients with mediastinal lymph node metastases and 3 patients with distant metastases. After chemoradiotherapy，3 patients lived well but 2 patients died. None of the other patients had any severe complication during follow-up. Conclusion Complete video-assisted thoracoscopic lobectomy is a safe and effective surgical strategy for patients with benign or malignantpulmonary disease.
