A baby presented at term with respiratory distress was managed with extracorporeal membrane oxygenation. Bronchoscopy revealed tracheal hypoplasia, complete tracheal rings, and agenesis of the right main bronchus. Echocardiography showed a left pulmonary arterial sling arising from the proximal part of the right pulmonary artery. Cardiac catheterization demonstrated abnormal pulmonary vasculature in the left lung which would have prevented survival, even after surgical repair. Diagnostic catheterization was important in delineating the anatomy, and aided in the decision not to proceed with surgical repair.

Abstract Background Primary graft dysfunction (PGD) remains a major obstacle after lung transplantation. Ischemia–reperfusion injury is a known contributor to the development of PGD following lung transplantation. We developed a novel approach to assess the impact of increased pulmonary blood flow in a large porcine single-left lung transplantation model. Materials Twelve porcine left lung transplants were divided in two groups (n = 6, in low- (LF) and high-flow (HF) group). Donor lungs were stored for 24 h on ice, followed by left lung transplantation. In the HF group, recipient animals were observed for 6 h after reperfusion with partially clamping right pulmonary artery to achieve a higher flow (target flow 40–60% of total cardiac output) to the transplanted lung compared to the LF group, where the right pulmonary artery was not clamped. Results Survival at 6 h was 100% in both groups. Histological, functional and biological assessment did not significantly differ between both groups during the first 6 h of reperfusion. injury was also present in the right native lung and showed signs compatible with the pathophysiological hallmarks of ischemia–reperfusion injury. Conclusions Partial clamping native pulmonary artery in large animal lung transplantation setting to study the impact of low versus high pulmonary flow on the development of ischemia reperfusion is feasible. In our study, differential blood flow had no effect on IRI. However, our findings might impact future studies with extracorporeal devices and represent a specific intra-operative problem during bilateral sequential single-lung transplantation.

AbstractMowat–Wilson syndrome is a genetic condition due to a mutation in the ZEB2 gene; it affects many systems including the cardiovascular system. The pulmonary arterial sling originates from a failure of development of the proximal portion of the left sixth aortic arch, resulting in an anomalous left pulmonary artery origin from the posterior wall of the right pulmonary artery and the left pulmonary artery crossing to the left lung between the trachea and the oesophagus. We present a 4-month-old infant with Mowat–Wilson syndrome and left pulmonary arterial sling, and discuss the association of these two rare conditions. Pulmonary arterial sling is significantly more frequent in patients with Mowat–Wilson syndrome than in the general population.

We present the case of a 4-year-old girl, bronchofiberscopy (scope diameter 2.8mm): one third below oftrachea, which was divided into two orifices. The orifice on the right side was larger and divided into twosuborifices. The left orifice was stenosis and could not pass the bronchoscope. Whole trachea mucosa was redand edema, and could not observe the cartilage ring of trachea. Chest X-ray: infiltration of right lower lobe.Chest CT multiple probes with contrast injection confirmed that: At the sixth to seventh thoracic vertebral level,the left pulmonary artery was arisen from the right pulmonary artery then passed in between the behindtrachea and anterior oesophagus to reach the left lung hilar. And at the fourth to fifth thoracic vertebral level,the right upper bronchus was arisen from trachea and then the trachea was shrunk diameter to reach the leftlung hilar, at the end, the trachea divided 2 bronchi: left main bronchus and “bridging bronchus”. Thatbronchus from left lung hilar returned to the right lung.This patient was diagnosed birth defect: Left pulmonary artery sling with trachea stenosis, type IIA.
