Objectives: To measure pulmonary artery and aortic calibers, and calculatingmain pulmonary artery to ascending aorta ratio in healthy children, to verify the adult ratio of1:1. Study Design: Observational study. Place and duration of study: Radiology Department,Combined Military Hospital, Peshawar from 15 July 2015 to 14 July 2016. Methodology:Chest CT cans of 283 healthy children, with no history or predisposing causes of pulmonaryhypertension, performed between July 2015 and July 2016, were retrospectively studied.Diameters of pulmonary artery and aorta were measured on CT chest, at the level of bifurcationof the main pulmonary artery, and the ratio of pulmonary artery to ascending aorta wascalculated. Results: The average diameter of the main pulmonary artery, right pulmonary arteryand left pulmonary artery were 19 mm, 12.1 mm and 12.2 mm respectively. The diameter of theascending aorta was determined to be 12.2 mm and descending aorta was 13.67 mm. Ratio ofthe main pulmonary artery to ascending aorta was 1.06, which was higher than the adult ration,usually taken as <0.9. Conclusion: The measurement criteria devised for early detection ofpulmonary hypertension have different set of values when considering pediatric population ascompared to adults. Main pulmonary artery to ascending aorta ratio is significantly higher inhealthy children of all ages as compared to adults. CT scan is an excellent minimally invasivemodality in evaluation of the mediastinal vasculature.

Abstract Objective: This study is designed to explore the dual-source computed tomography (DSCT) imaging manifestations of the origin of three rare pulmonary artery abnormalities, and to improve the understanding and diagnosis of the disease.Methods: Collected 30 cases of patients diagnosed by DSCT with pulmonary artery abnormal origins, and retrospectively analyzed their imaging data and postoperative pathological data.Results: Among the 30 patients with abnormal pulmonary artery origin, 16 patients were with unilateral pulmonary artery absence (UAPA), 8 patients were with anomalous origin of unilateral pulmonary artery (AOPA), and 6 patients were left pulmonary artery suspension (LPAS). The diagnosis rate of DSCT is significantly higher than that of echocardiography. The results of DSCT imaging showed that the inner diameter of the ascending aorta, the aortic arch and the descending aorta of UAPA patients were significantly larger than those of LPAS patients (P<0.05). Compared with AOPA patients, the left pulmonary artery diameter, the ratio of the left main pulmonary artery diameter to the main pulmonary artery diameter, and ratio of the left main pulmonary artery diameter to the right main pulmonary artery diameter were significantly increased in UAPA patients (P<0.05). There was no significant difference in the ratio of the inner diameter of the ascending aorta to the descending aorta in patients with UAPA, AOPA and LPAS. Compared with UAPA patients, AOPA patients had no significant changes in the inner diameter of the main pulmonary artery, the inner diameter of the right main pulmonary artery, and the ratio of the inner diameter of the right main pulmonary artery to the main pulmonary artery.Conclusion: DSCT can be used to diagnose the origin of pulmonary artery abnormalities and distinguish its types.

A B S T R A C T Objective: To investigate the relationship between gastric wall fat halo sign and potentially associated cardiovascular disease (CVD) in thoracic computed tomography (CT). Material and Methods: Between October 2018 and June 2019, 62 patients with gastric wall fat halo sign and 97 controls were prospectively evaluated. Patient height, weight, body mass index (BMI), sex, age, ascending aorta, descending aorta, main pulmonary artery, right and left pulmonary artery, long and short cardiac axis and maximum transverse thorax diameters; and ascending, arcus, descending aorta and coronary artery calcium scores were recorded for the two groups. Results: No significant differences were found in sex, age, height, body weight or BMI between the two groups (p > 0.125). Patients with gastric wall fat halo sign had significantly larger diameters of the ascending aorta, the descending aorta, the main pulmonary artery, the right and left pulmonary arteries, and the short and long cardiac axes and a higher cardiothoracic ratio (CTR) than the control group (p < 0.001). Additionally, the calcium scores of the ascending, arcus, and descending aortas and the coronary arteries were significantly higher detected in patients group (p < 0.001). Conclusion: The gastric wall fat halo is the result of excessive fat accumulation and can be observed in overweight people, especially those with increased visceral fat tissue. Additionally, patients with a gastric wall fat halo have a higher cardiovascular risk because of increased vascular diameters, CTR, heart sizes and calcium scores.

Background Anomalous origin of the left pulmonary artery (ALPA) from the ascending aorta (AA) is a rare congenital heart malformation. Aim To give some of our embryological considerations of ALPA from the AA. Methods We present a patient with ALPA from the AA, right-sided aortic arch, right-sided ductus arteriosus (DA), and aberrant left subclavian artery (LSCA). Results The distal end of ALPA was cut off, the proximal end was sutured, and the distal end was directly anastomosed to the left wall of the main pulmonary artery (MPA). Conclusion The failure of migration and differentiation of cardiac neural crest cells at the fourth and sixth archs result in unilateral arch agenesis or failure of detachment of the left sixth arch from the aortic sac, which form ALPA the AA.

Echocardiographic Findings

Anomalous pulmonary artery arising from the aorta is a rare congenital anomaly. The midterm results of repair of this malformation by Gore-Tex graft interposition were examined in 5 patients: 3 with anomalous right pulmonary artery and 2 with anomalous left pulmonary artery from the ascending aorta. Echocardiography was adequate in 4 cases for diagnosis, planning the operation, and follow-up. Angiography was needed for diagnosis in one case where the echocardiographic findings were unclear. The mean follow-up period was 4 years. One patient with tracheoesophageal fistula and cardiac malformation died 2 months after the operation due to multi-organ failure. Three patients needed re-operation because of graft narrowing, and one was without problems 5.2 years postoperatively. In anomalous pulmonary artery from the ascending aorta, repair should be performed as early as possible to prevent pulmonary hypertensive changes. When the anomalous pulmonary artery cannot be anastomosed directly to the main pulmonary artery, an interposition graft can be placed safely without cardiopulmonary bypass. With appropriate follow-up, this can be a satisfactory solution, although it carries the risk of re-operation due to graft narrowing.

Severe Aortic Regurgitation

Background: The presence of a bicuspid aortic valve (BAV) might be associated with a progressive dilatation of the aortic root and ascending aorta. However, involvement of the aortic arch and descending aorta has not yet been elucidated. Patients and methods: Magnetic resonance angiography (MRA) was used to assess the diameter of the ascending aorta, aortic arch, and descending aorta in 28 patients with bicuspid aortic valves (mean age 30 ± 9 years). Results: Patients with BAV, but without significant aortic stenosis or regurgitation (n = 10, mean age 27 ± 8 years, n.s. versus control) were compared with controls (n = 13, mean age 33 ± 10 years). In the BAV-patients, aortic root diameter was 35.1 ± 4.9 mm versus 28.9 ± 4.8 mm in the control group (p < 0.01). The diameter of the ascending aorta was also significantly increased at the level of the pulmonary artery (35.5 ± 5.6 mm versus 27.0 ± 4.8 mm, p < 0.001). BAV-patients with moderate or severe aortic regurgitation (n = 18, mean age 32 ± 9 years, n.s. versus control) had a significant dilatation of the aortic root, ascending aorta at the level of the pulmonary artery (41.7 ± 4.8 mm versus 27.0 ± 4.8 mm in control patients, p < 0.001) and, furthermore, significantly increased diameters of the aortic arch (27.1 ± 5.6 mm versus 21.5 ± 1.8 mm, p < 0.01) and descending aorta (21.8 ± 5.6 mm versus 17.0 ± 5.6 mm, p < 0.01). Conclusions: The whole thoracic aorta is abnormally dilated in patients with BAV, particularly in patients with moderate/severe aortic regurgitation. The maximum dilatation occurs in the ascending aorta at the level of the pulmonary artery. Thus, we suggest evaluation of the entire thoracic aorta in patients with BAV.
