Objective:To sum up the experience of surgical repair for infants with absence of right pulmonary artery(ARPA) in our hospital to improve the treatment of ARPA.Methods:From February 2019 to April 2019, 3 infants with ARPA underwent surgical repair in our hospital, aged from 33-day to 20-month. We took enhanced CT scan with three-dimensional reconstruction and pulmonary vein wedge angiography(PVWA) to confirm the diagnosis and to assess the surgical indications. We explored to mobilize the atresia patent ductus arteriosus(PDA) and adopted "two-segment" technique to reconstruct the absent pulmonary artery. The blood flow in the "neo" pulmonary artery, the improvement of the pulmonary hypertension and anticoagulant therapy were followed up closely after the operation.Results:There were particular traces on CT reconstruction images which were very important cues for cardiac surgeons inferring potential approaches during the operation, such as the aberrant "diverticulum" or "bud" in the position of the base of the innominate artery in all 3 infants which were confirmed as one end of the atresia PDA connecting the right pulmonary hilum; PVWA which can clearly show the development and distribution of the pulmonary vessels within the lung was taken in one patient. Significant alleviation of pulmonary hypertension happened immediately after the RPA reconstruction; 3 patients recovered smoothly. During early follow-up, RPA thrombosis happened in one patient was cured by continuous pumping anticoagulation with heparin. Now warfarin or aspirin was used with close follow-up.Conclusion:ARPA is not "no-fly zone" for surgical correction. Earlier diagnosis and pulmonary reconstruction in infant could get excellent early result. Some particular aberrant "diverticulum" on CT reconstruction images are important cues with PVWA still being the golden standard for diagnosis and assessment.

Objective Retrospectively analyze surgical correction supracardiac total anomalous pulmonary venous con-nection (TAPVC) using sutureless technique to prevent post-repair pulmonary vein stenosis. Methods Between December 2007 and December 2008, 25 children cases of total anomalous pulmonary venous connection underwent primary surgical cor-rection. The anatomic types of TAPVC were supra cardiac in nine patients, inha cardiac in one, mixed in 3 and intra cardiac in 12. Five of nine supra cardiac TAPVC underwent correction using sutureless technique. There were 2 male and 3 female. Their age at surgeries ranged from 2 months to 13 years, and the body weight were from 4.5 kg to 2.1 kg with an average of (7.9±6.4) kg. After median sternotomy and opening the pericardium, the heart was arrested by delivering cold crystal ear-dioplegia. The heart was then positioned toward the patient' s right and under the right henri sternum. A generous incision across the posterior wall of the left atrium and one on the common pulmonary vein was made. The latter was extended upwards to the midpoint of the vertical vein. The left atrium was subsequently connected to the pulmonary venous confluence by suturing the edge of the atrium to the posterior mediastinal pericardium that surrounding the common pulmonary vein and the vertical vein with 7-0 PDS. The vertical vein was partially ligated after conclusion of CPB, leaving a diameter of 5mm shunt. Routine follow-up with echocardiogram were at diacharging, 3 months, 6 months and 1 year after surgery. Results All 5 cases survived uneventfully excopt 1 baby on ventilation over 7 days after surgery, who had bilateral lung consolidation before the operation. Echocardiogram showed satisfactory results with maxium velocity acrossing the anastomosis of 0.65 -0.85 m/s. Conclusion Sutureleas technique can avoid trauma to the pulmonary venous endothelium and minimize the tension of anastomasis. It may play an important role to prevent post-repair pulmonary vein stenosis. More patients with long-term follow-up are necessary to draw a definite conclusion of this technique.
