Case Report: Successful primary sutureless repair of common pulmonary vein atresia in a neonate

Figures

  Figure 1. Chest x-ray soon after birth in a neonate with CPVA shows indistinct vascular markings, reduced pulmonary translucency, and normal cardiac silhouette. CPVA, common pulmonary vein atresia.

• 

  Figure 2. Cardiac CTA (A) with three-dimensional reconstruction (B) demonstrates a CPVC (blue arrow) and ascending vertical vein (white arrow), forming a tortuous vascular mass (orange arrow) anterior to the trachea and posterior to the SVC (green arrow) in the patient. CTA, computed tomographic angiography; CPVC, common pulmonary venous chamber; SVC, superior vena cava.

  Figure 3. Schematic illustration of the sutureless technique for repair of CPVA. (A) A transverse incision was made across the CPVC, and a longitudinal incision was performed along the left atrial appendage. (B, C) The pericardial tissues surrounding the CPVC and left atrium were anastomosed to create a wide, tension-free opening without direct suturing of the pulmonary vein. AO, aorta; CPVA, common pulmonary vein atresia; CPVC, common pulmonary venous chamber; IVC, inferior vena cava; LA, left atrium; LIPV, left inferior pulmonary vein; LPA, left pulmonary artery; LSPV, left superior pulmonary vein; LV, left ventricle; MPA, main pulmonary artery; RIPV, right inferior pulmonary vein; RPA, right pulmonary artery; RSPV, right superior pulmonary vein.

  Figure 4. Two-dimensional echocardiography in the immediate postoperative period after sutureless repair of CPVA shows unobstructed pulmonary venous drainage into the left atrium. CPVA, common pulmonary vein atresia; RA, right atrium; LA, left atrium.
