“…In our study, the most common pulmonary artery anomalies were atresia, stenosis, and hypoplasia. Liu et al [16] stated that pulmonary atresia is a rare anomaly with a prevalence of approximately 1 in 200,000, but in our study, it was the most common anomaly with 16 cases; it may be because our hospital is a tertiary referral. Leonard et al [17] classified pulmonary atresia into three types, pulmonary atresia with the intact interventricular septum, pulmonary atresia with VSD, and complex pulmonary atresia.…”

Background: Congenital pulmonary artery anomalies are variable and need proper diagnosis and treatment. CT angiography with multiplanar reconstruction has the main role in the assessment of these anomalies and this noninvasive method should be the method of choice for preoperative planning and postoperative follow up. The aim of the study is to assess the value of MDCT in the detection of pulmonary arteries anomalies in the pediatric population with complex congenital heart disease in conjunction with echocardiography as an alternative to conventional angiography and to determine the superiority of MDCT in the assessment of other abnormalities such as airway anomalies. Results: In our retrospective study, 52 patients (28 male and 24 females, aged 1 day to 4 years: mean age 2 years) were examined with contrast-enhanced CT. CT examinations were done using a 128-section CT scanner (Siemens Somatom Definition AS) using non-ionic iodinated contrast media. 2D and 3D reconstructions were performed. The correlation was made with echocardiograms. All imaging studies were reviewed. The echo was done to all patients. Surgery and/or catheter angiography performed to all patients, their findings were reviewed and compared to CTA findings. Other abnormalities such as congenital airway anomalies are detected using axial MDCT images and reconstructed imaging techniques. MDCT was accurate in revealing pulmonary artery anomalies. The commonest pulmonary artery anomaly was atresia, stenosis then hypoplasia. These anomalies may be isolated or associated with other congenital heart diseases. In the current study, MDCT could diagnose all cases of pulmonary arterial anomalies with 96% sensitivity, 100% specificity, 98% accuracy, 100% positive, and 94% negative predictive values. CT scans provide accurate information to assess complex spatial relationships of vascular airway compression frequently associated with CHD in the pediatric population. Conclusion: MDCT scanner can be an alternative to diagnostic conventional angiography for the non-invasive assessment of the pulmonary artery. Higher quality multiplanar and 3D reconstruction achieved by the MDCT scanners offer a rapid, reliable and non-invasive technique that can be used for the evaluation and preoperative assessment of thoracic vascular and extra-vascular anatomy in infants and children with suspected congenital heart disease. CT technologies are constantly developing collaboration between radiologists, pediatric cardiologists, and anesthesiologists, which is essential for improving CT performance.

“…In asymptomatic patients, some clinicians adopt con-servative management with close follow-up. Others seek to restore physiological pulmonary functionality via early revascularization of the interrupted pulmonary artery and embolization of any ruptured collateral vessels, if symptoms warrant it (5,7,8,10).…”

A 42 year old lady presented with dyspnea and 3 episodes of hemoptysis since 1 day. Her chest radiograph revealed mild peripheral fibrosis & volume loss in right lung, subsequent HRCT confirmed the findings with additional diagnosis of absence of the right main pulmonary artery. This was further confirmed on digital subtraction angiography and the right lung was solely supplied by the systemic circulation. The conventional angiography did not demonstrate any active extravasation or blush to suggest active bleeder. Empirical embolization was not attempted due to a risk of pulmonary infarction. Patient was managed symptomatically and conservatively.This condition is important to recognize in the list of differential diagnoses for pulmonary artery abnormalities and any acquired causes of pulmonary vasculature obstruction must be ruled out on imaging modalities.

“…Left-sided interruption of the pulmonary artery is often associated with concurrent congenital cardiac anomalies like tetralogy of Fallot, right aortic arch, aortic coarctation, patent ductus arteriosus, septal defects, and transposition of great arteries. [81][82][83] Right-sided defects are usually present in isolation. 18 The affected lung is supplied by systemic collateral vessels formed mainly by branches of the bronchial arteries but also by collaterals from the intercostal, internal mammary, subclavian, subdiaphragmatic, or innominate arteries.…”

“…84 The incidence of PH in this condition is variable and reportedly varies from 19 to 44%. 81,83 UPPA is often suspected after a chest radiograph is obtained for other purposes and shows abnormalities suspicious of this condition. On a plain chest radiograph, the mediastinum is shifted to the affected side, the ipsilateral hemidiaphragm may be elevated and there is compensatory hyperinflation of the lungs on the unaffected side.…”

Chronic thromboembolic pulmonary hypertension (CTEPH) is caused by mechanical obstruction of large pulmonary arteries secondary to one or more episodes of pulmonary embolism. Ventilation perfusion scan is the recommended initial screening test for this condition and typically shows multiple large mismatched perfusion defects. However, not all patients with an abnormal ventilation perfusion scan have CTEPH since there are other conditions that be associated with a positive ventilation perfusion scan. These conditions include in situ thrombosis, pulmonary artery sarcoma, fibrosing mediastinitis, pulmonary vasculitis and sarcoidosis, among others. Although these conditions cannot be distinguished from CTEPH using a ventilation perfusion scan, they have certain characteristic radiological features that can be demonstrated on other imaging techniques such as computed tomography scan and can help in differentiation of these conditions. In this review, we have summarized some key clinical and radiological features that can help differentiate CTEPH from the CTEPH mimics.
