Background: Anomalous systemic arterial supply to the left basal segment of the lung is a rare congenital pulmonary vascular malformation, historically classified as a variant of intra-lobar pulmonary sequestration. The standard surgical approach has typically involved ligation of the anomalous artery in combination with lobectomy or segmentectomy.
Case Description: We present three cases of anomalous systemic arterial supply to the left basal segment of the lung, all successfully treated with thoracoscopic anomalous arterial ligation alone. In one case, indocyanine green was used to assess the blood supply, enhancing procedural safety.
Conclusion: Thoracoscopic ligation of the anomalous artery alone may be a safe and lung-preserving surgical option for patients with this rare anomaly. The use of indocyanine green can further improve the safety of the procedure.

Outcomes of the lateral caval flap and conventional techniques for repair of right-sided partial anomalous pulmonary venous connection in adults.

Objective: In an effort to overcome limitations of conventional techniques for surgical repair of partial anomalous pulmonary venous connection (PAPVC), we developed the lateral caval flap (LCF) technique, which leverages a native endocardial surface to create unobstructed recruitment of the anomalous pulmonary veins to the left atrium. In this study, we report the long-term outcomes of the LCF and conventional techniques for repair of right-sided PAPVC.
Methods: In total, 109 adult patients (mean age 48 years; 57% male) who underwent right-sided PAPVC repair (53 LCF, 34 single-patch, 13 double-patch, 7 pericardial roll, and 2 Warden procedure) from 1997 to 2022 were retrospectively reviewed.

Obstructed infracardiac total anomalous pulmonary venous connection with patent ductus venosus: possibility of emergency palliation.

Background: Patients with obstructed infra-cardiac total anomalous pulmonary venous connection (TAPVC) require urgent intervention to relieve the obstruction, with or without restoration of anatomical continuity between the pulmonary veins and the left atrium. In cases of infra-cardiac TAPVC draining into the inferior vena cava (IVC) or hepatic vein, the obstructed channel can be accessed via the systemic venous approach for endovascular palliation. However, in cases of infra-cardiac TAPVC draining into the portal venous system, an endovascular approach to the obstructed channel is not possible via the transfemoral route and may require direct percutaneous puncture of the splenoportal axis.

We present an interesting case of a 17-year-old boy who experienced shortness of breath while playing. He was diagnosed to have an aberrant artery supplying the right lower lobe of the lung arising from the descending thoracic aorta on imaging. Thoracoscopic ligation of the aberrant vessel was done.

Background: Anomalous origin of the right pulmonary artery (AORPA) from the ascending aorta is a rare congenital anomaly, representing approximately 0.12% of all congenital heart defects. Early diagnosis and timely intervention are essential to prevent severe complications such as heart failure and pulmonary vascular disease.
