Infants with vascular rings typically present before 12 months with respiratory or esophageal symptoms like stridor, wheezing, cough, dysphagia, or difficulty feeding. The stridor improves with neck extension, differentiating from laryngomalacia which is relieved by prone or upright positioning, and will not be relieved with corticosteroids or ...
In the absence of imaging, either invasive (e.g. laryngoscopy) or non-invasive (e.g. computed tomography scan), congenital VFP can be detected in infants through the presence of stridor (i.e. a high-pitched wheezing resulting from a blockage in the larynx or trachea), difficulties feeding, an abnormal sounding cry or excessive hoarseness. [8]
It is the most serious in young children, possibly because of the relatively small size of the trachea that gets easily blocked by swelling. The most frequent sign is the rapid development of stridor. It is occasionally confused with croup. If it is inflamed, a condition known as tracheitis can occur.
Symptoms can be mild to severe. [citation needed] Symptoms inside the lung include noisy breathing that may get better when you change your baby's position or while he or she is asleep. Breathing problems that get worse during coughing, crying, feeding or colds. High-pitched sound during breathing (stridor). High-pitched cough.
The main difference between VCD and asthma is the audible stridor or wheezing that occurs at different stages of the breath cycle: VCD usually causes stridor on the inhalation, while asthma results in wheezing during exhalation. [5] [6] [7] Patients with asthma usually respond to the usual medication and see their symptoms resolve.
Respiratory sounds, also known as lung sounds or breath sounds, are the specific sounds generated by the movement of air through the respiratory system. [1] These may be easily audible or identified through auscultation of the respiratory system through the lung fields with a stethoscope as well as from the spectral characteristics of lung sounds. [2]
Some infants have feeding difficulties related to this problem. Rarely, children will have significant life-threatening airway obstruction. The vast majority, however, will only have stridor without other more serious symptoms such as dyspnea (difficulty breathing). [citation needed]
Respiratory symptoms and signs that may be present include shortness of breath, wheezes, or stridor. [4] The wheezing is typically caused by spasms of the bronchial muscles [19] while stridor is related to upper airway obstruction secondary to swelling. [18] Hoarseness, pain with swallowing, or a cough may also occur. [15]
