Pulmonary arterial sling (PAS) is a relatively rare congenital anomaly in which left pulmonary artery branch originates abnormally from the right pulmonary artery, eventually resulting with respiratory symptoms, due to airway obstruction. In this report, we present a PAS in a neonate who showed progressive respiratory distress in the second week following delivery. At 25 days of age, the patient underwent total surgical correction of the anomaly, during which left pulmonary artery reimplantation to main pulmonary artery without the use of cardiopulmonary bypass was employed. Following an uneventful recovery, the patient was discharged eighteen days after surgery.

Pulmonary Artery Sling (PAS) is a rare congenital heart disease due to abnormal origin of Left Pulmonary Artery (LPA) from the Right Pulmonary Artery (RPA), then encircling the distal part of the trachea. The treatment is a surgical repair consisting of reimplantation of the LPA on the main pulmonary artery over cardiopulmonary bypass. The authors report a clinical case of PAS in a 5.5 years old boy diagnosed in Senegal then successfully operated in France.Cardiovasc. j. 2017; 10(1): 94-96

Cardiovascular Anomalies

Pulmonary artery sling (PAS) is a rare congenital cardiovascular abnormality. In typical PAS patients, the left pulmonary artery (LPA) arises from the right pulmonary artery and passes between the trachea and esophagus, which possibly causes tracheal stenosis and some respiratory symptoms. PAS typically associates with other cardiovascular anomalies, which may cause difficulties to the treatment of patients. This report described a rare case of a two-month-old boy with PAS, VSD, and tracheal stenosis simultaneously and underwent procedures without tracheoplasty.

Systemic Arterial Supply

AbstractIn a girl suffering from “Scimitar syndrome”, a rerouting of the scimitar vein was performed at the age of 6 years, but no embolisation of the aberrant systemic vessel was done. She presented with recurring respiratory problems 13 years later. An angiography revealed an invert flow from the aberrant systemic vessel via the right pulmonary artery into the left pulmonary artery. After pneumonectomy, she recovered well.

AbstractMajor abnormalities of pulmonary circulation are uncommon in the patient with pulmonary atresia and intact ventricular septum. Non-confluent pulmonary arteries have only rarely been described in this setting. In this case report, we describe a patient in whom the pulmonary arteries are non-confluent, with the right pulmonary artery supplied through a right-sided arterial duct, and the left pulmonary artery most likely through a fifth aortic arch, thus providing a systemic-to-pulmonary arterial connection. We discuss the various forms of non-confluent pulmonary arteries in the setting of pulmonary atresia and intact ventricular septum.

We report a case of a partial anomalous left pulmonary artery sling in an adult patient as an incidental finding on computed tomography. There is a normal bifurcation of the pulmonary trunk into right and left pulmonary arteries with anomalous origin of the left upper lobe pulmonary artery from the right pulmonary artery. The anomalous vessel passes between the trachea and esophagus forming a partial left pulmonary artery sling without airway compression.

The purpose of these experiments was to quantify stagnant intrapulmonary blood caused by a pulmonary arterial occlusion (PAO). The hypothesis was that the diffusing capacity of the lung for CO (DLCO) would be altered little by PAO when measured with the usual inspired concentrations (0.3%) of CO, since stagnant blood distal to the occlusion takes up CO for 20 s or more before significant CO backpressure would develop. However, higher levels of CO (i.e., greater than or equal to 3%) would equilibrate faster with capillary blood (within 5-10 s), and DLCO measured 10-20 s subsequent to the high CO exposure would reflect only the DLCO in the unoccluded regions. Thus the fractional reduction in DLCO measured with 3% CO, with respect to that measured with 0.3% CO, should be related to the fractional occlusion of the pulmonary artery in a predictable way. We occluded the right pulmonary artery (RPAO), the left pulmonary artery (LPAO), or the left lower lobar artery (LLPAO) and found that DLCO measured during rebreathing a 0.3% CO mixture was 80, 87, and 94%, respectively, of the preocclusion value, whereas the DLCO measured during rebreathing a 3.3% CO mixture was 59, 73, and 87% of the preocclusion value. A computer model was developed to predict the reduction in DLCO at different levels of CO exposure that would be caused by varying fractions of PAO. Our data indicated that RPAO corresponded to a 42% vascular occlusion, LPAO a 35% occlusion, and LLPAO a 20% occlusion. Measurement of DLCO using low and high concentrations of CO might be useful in assessing the fraction of vascular bed occluded and in following noninvasively the course of vascular occlusion in a variety of pulmonary diseases.

In-vitro pulsatile flow visualization studies were conducted in an adult-sized pulmonary artery model to observe the effects of valvular pulmonic stenosis on the flow fields of the main, left and right pulmonary arteries. The flow patterns revealed that as the degree of stenosis increased, the jet-type flow created by the valve became narrower, and it impinged on the far (distal) wall of the left pulmonary artery further downstream from the junction of the bifurcation. This in turn led to larger regions of disturbed turbulent flow, as well as helical-type secondary flow motions in the left pulmonary artery, compared to the right pulmonary artery. The flow field in the main pulmonary artery also became more disturbed and turbulent, especially during peak systole and the deceleration phase. The flow visualization observations have been valuable in helping to conduct further quantitative studies such as pressure and velocity field mapping. Such studies are important to understanding the fluid mechanics characteristics of the main pulmonary artery and its two major branches.

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.
