Abstract
According to clinical features and ultrasonic imaging features of patients with absence of pulmonary artery, it is necessary to analyze ultrasonic imaging features of absence of pulmonary artery to provide clinical basis for improving the diagnostic value and prognosis. The data and
color Doppler echocardiography of 45 patients with absence of pulmonary artery are collected, who are confirmed by cardiac catheterization, CTA and operation, and the clinical features and ultrasonic imaging features are studied. The research results show that 57% of the patients have left
absence of pulmonary artery and 91% of them have other cardiovascular malformations, where ASD/PFO is the most common, PDA and VSD are the second. Patients with UAPA have changes of pulmonary artery, the incidence of pulmonary artery abnormalities in multiple malformations, changes of ASD/PFO,
PDA and VSD are mainly pulmonary hypertension. The ejection fraction of patients with UAPA is normal. The main manifestation of pulmonary hypertension is the increase of right cardiac volume load, and the main manifestation of pulmonary stenosis is the increase of collateral circulation. Pulmonary
hypertension and its associated cardiovascular malformations may be related to the prognosis of patients. Ultrasound doctors should understand such diseases to improve the diagnosis rate and the prognosis.
