“…This case also demonstrated the results of pulmonary perfusion and pulmonary function in a patient with PAS before and after left lower lobectomy. The preoperative pulmonary perfusion of this patient revealed a mildly asymmetric flow to the left lung (31.4%) and right lung (68.8%), which is similar to a previously reported case ( 8 ). After the left lower lobectomy, the predicted left pulmonary perfusion of the total pulmonary perfusion was 16.6% and the actual left pulmonary perfusion accounted for 18.0%.…”

IntroductionPulmonary artery sling (PAS) is a rare congenital vascular anomaly that results when the left pulmonary artery arises from the right pulmonary artery. There is little relevant literature on lobectomy for the treatment of lung cancer in patients with PAS, and the prognosis is unknown.Case DescriptionA 54-year-old asymptomatic man was found to have a nodule on the left lower lobe of the lung, which measured 2.5 cm. The patient also had PAS. Three-dimensional computed tomography angiography confirmed that the left pulmonary artery arose from the right pulmonary artery and passed between the main trachea and the esophagus toward the left thorax. No obvious contraindication was found in the preoperative examination, and the patient successfully underwent lobectomy of the left lower lobe by video-assisted thoracoscopic surgery. Histological examination of the lesion revealed invasive adenocarcinoma. The postoperative course was uneventful, and no complications occurred in the subsequent 3 years of follow-up.ConclusionsLobectomy in a lung cancer patient with PAS did not increase perioperative risk and had no significant effect on prognosis.

“…Other clinical manifestations may include dysphagia (which is not much common) due to compression of the esophagus, failure to thrive, and recurrent chest infections [4]. In some reports, pulmonary artery sling remained asymptomatic until childhood [14]. Indeed, patients may just complain of mild symptoms/signs and present in late childhood or adulthood with nonspecific respiratory symptoms like chest pain, cough, orthopnea, and exertional symptoms [15][16].…”

Pulmonary artery sling is a rare cause of neonatal respiratory distress. Most patients with pulmonary artery sling present in early infancy with stridor and signs of respiratory distress. Diagnosis of pulmonary artery sling, like other vascular ring anomalies, can be made using various imaging modalities, and management encompasses urgent surgical repair as a definitive treatment. This is the first paper to report a successfully managed case of an early detected left pulmonary artery sling during the first week of life in a term male patient and to evaluate the diagnostic characteristics in alliance with it. CAse REports (CARE) guidelines were followed for reporting our case. In brief, a case of full-term baby boy was born by normal vaginal delivery and shortly after birth, the baby started to have respiratory distress not improving on O 2. Chest X-ray revealed right upper lobe atelectasis which persisted despite mechanical ventilation and antibiotics. A thoracic CT scan showed developmental malformation of left main pulmonary artery, confirming the diagnosis of "left pulmonary artery sling." The baby was immediately operated. One week later, chest X-ray showed gradual improvement and the baby was discharged home with no postoperative complications. Hence, we suggest that pulmonary artery sling should be suspected in any neonate with respiratory distress and unilateral lung field opacification. The fact that there are only very few reports on this disease raises a need to establish and implement well-defined guidelines and criteria for early diagnosis and management of pulmonary artery sling among newborns.

Background Left pulmonary artery (LPA) sling is a rare anomaly characterized by the origin of the LPA from the right pulmonary artery with a course between the trachea and esophagus. It is often associated with airway and cardiac anomalies. Methods This is a retrospective case series of consecutive patients who underwent LPA sling repair (LPASR) at a tertiary care center over a 35-year period with a focus on tracheal and/or LPA reinterventions and survival. Results Between June 1983 and July 2018, 42 patients were identified: isolated LPASR was performed in 16 (38%), LPASR/intracardiac repair in 10 (24%), and LPASR/tracheal repair in 16 (38%). There were 5 (12%) in-hospital and 4 (10%) late deaths. Survival rates (15 years) were as follows: 100% (isolated LPASR), 65% (concomitant intracardiac repair), and 52% (concomitant tracheal surgery). Preoperative intensive care unit (ICU) hospitalization was associated with future intervention on the LPA/trachea (61%, 11/18). The median distribution of blood flow to the left lung post-index surgery was 38%. Freedom from isolated LPA intervention was 100% after isolated LPASR, 93% after LPASR/tracheal surgery, and 69% after LPASR/intracardiac repair. Freedom from isolated tracheal intervention was 92% after isolated LPASR, 73% after LPASR/tracheal surgery, and 78% after LPASR/intracardiac repair. Conclusions ICU hospitalization prior to index surgery may indicate the severity of associated cardiac/tracheal abnormalities as this is associated with increased morbidity and mortality. Patients who underwent LPASR/intracardiac surgery were more likely to undergo isolated LPA intervention and those who underwent LPASR/tracheal surgery were more likely to undergo isolated tracheal intervention.
