Pulmonary vascular sling: Report of seven cases and review of the literature

  • Betty M. Gikonyo

A total of 130 cases of pulmonary vascular sling, including seven new cases in our collection, were studied. The sex distribution was 60% male and 40% female. The age at presentation was in the first year of life in ∼90% of cases. Barium-esophagraphy showing anterior indentation was diagnostic in most of the cases. Bronchoscopy and tracheobronchography were useful in detecting associated tracheobronchial anomalies preoperatively. The analysis of 68 autopsied cases revealed associated tracheobronchial anomalies in 40% of the cases. Anomalies of the tracheobronchial tree took three major forms: abnormal distribution of cartilage in the walls of the trachea and major bronchi, intrinsic stenosis, and abnormal branching, the latter being that ofbronchus suis. Acquired changes secondary in the sling resulted in compression of the major respiratory pathway by the anomalous left pulmonary artery. Major associated cardiovascular anomalies were present in 30% of the cases. These were represented by ventricular septal defect, atrial septal defect, patent ductus arteriosus, tetralogy of Fallot, common ventricle, and coarctation of the aorta.
