Similarly, watch this group of patients closely for the possibility of left pulmonary artery stenosis after reimplantation of the vessel. This can be assessed noninvasively with echocardiography but rarely may require follow-up pulmonary artery angiography. Patients hospitalized with significant stridor, in whom a vascular ring or pulmonary artery sling is suspected, should be transferred to a facility that can provide pediatric cardiology and pediatric cardiovascular surgery services. Left pulmonary artery stenosis may occur and can be progressive. With early diagnosis and surgical correction, prognosis is good.
Surgical mortality is increased by coexisting tracheal or bronchial stenosis.
Patients in the immediate postoperative period still may be at risk during respiratory illnesses because of increased secretions. Case report and collective review. Anomalous left pulmonary artery causing obstruction to the right main stem bronchus. The aortic arch and its malformations with emphasis on its angiographic features. Medicine is a constantly changing science and not all therapies are clearly established.
