Since 1976, we have operated on 4 children with pulmonary vascular sling. They were 5, 12, 19, and 54 months old. All patients were seen initially with severe stridor. Diagnosis was made by barium swallow in all 4. Each child was operated on through a left thoracotomy; the left pulmonary artery was dissected deep between the trachea and esophagus. Systemic heparinization and microsurgical techniques were used. All patients improved after operation. Radioisotope pulmonary ventilation/perfusion scans were performed 9, 9, 14, and 21 months after operation. Decreased ventilation was noted in the right upper lobe of one scan; the other three ventilation scans were normal. Perfusion scans showed good patency of both pulmonary arteries in all 4 patients. It is concluded that pulmonary vascular slings should be treated surgically as soon as diagnosed. Delayed operation can lead to severe tracheomalacia, as demonstrated in our 54-month-old patient.
自1976年以来，我们已为4例患有肺血管吊带的儿童进行了手术。他们的年龄分别为5个月、12个月、19个月和54个月。所有患者最初均表现为严重的喘鸣。4例患者均通过吞钡检查确诊。每个孩子都通过左胸切口进行手术；在气管和食管之间深部解剖左肺动脉。采用全身肝素化和显微外科技术。所有患者术后均有改善。术后9个月、9个月、14个月和21个月进行了放射性核素肺通气/灌注扫描。其中一次扫描显示右上叶通气减少；其他三次通气扫描正常。灌注扫描显示所有4例患者的双肺动脉通畅良好。结论是，肺血管吊带一经诊断应立即进行手术治疗。延迟手术可导致严重的气管软化，正如我们54个月大的患者所显示的那样。
