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.

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.

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 Background Unilateral pulmonary artery discontinuity is a rare malformation that is associated with other intracardiac abnormalities. Cases accompanied by other cardiac abnormalities are often missed on prenatal echocardiography. The prenatal diagnosis of isolated unilateral pulmonary artery discontinuity can also be delayed. However, undiagnosed this malformation would have an effect on further prognosis. We report our case of a prenatal diagnosis of pulmonary atresia with ventricular septal defect and left pulmonary artery discontinuity. Case presentation A 33-year-old Asian woman visited our institution at 24 weeks of gestation because of suspected fetal congenital heart disease. Fetal echocardiography revealed a small atretic main pulmonary artery giving rise to the right pulmonary artery without bifurcation and the left pulmonary artery arising from the ductus arteriosus originating from the left subclavian artery. The neonate was delivered by cesarean section at 376/7 weeks of gestation. Postnatal echocardiography and multidetector computed tomography showed a right aortic arch, with the small right pulmonary artery originating from the atretic main pulmonary artery and the left pulmonary artery originating from the left subclavian artery. Patency of the ductus arteriosus from the left subclavian artery was maintained with prostaglandin E1. Right ventricular outflow tract reconstruction and pulmonary angioplasty with Gore-Tex graft patch was performed 25th day after birth. Unfortunately, the neonate died because of right heart failure 8 days postoperation. Conclusion There is a possibility that both pulmonary arteries do not arise from the same great artery (main pulmonary artery or common arterial trunk). Therefore, clinicians should check the origin of both pulmonary arteries.

We studied the detailed profiles of blood flow in the right and left pulmonary arteries using 20 MHz pulsed Doppler ultrasound equipment in a lamb model. Fourteen lambs aged four to six weeks were selected. In six lambs, monocrotaline pyrrole was injected parenterally to create pulmonary hypertension (PH group). Eight other lambs served as unaltered controls (control group). The blood flow velocities were sampled in 1mm increments along the anterior—posterior axis of the branch arteries. The maximum velocity of the forward flow in the left pulmonary artery was higher than that in the right pulmonary artery in the control group (71.7 ± 15.9cm/s vs 60.2 ± 13.5; p < 0.05). The fastest backward flow was located at the posterior position of the vessel in the right pulmonary artery in the control group. No significant bias in location was shown in the left pulmonary artery. Using indices of P90, acceleration time, P90*AcT, the velocity waveforms in the PH group were compared with those in the control group. In the left pulmonary artery, every index in the control group showed a significantly greater value that in the PH group. On the other hand, no significant differences were found between either group in the right pulmonary artery.

Detachable Coils

Transcatheter closure of patent ductus arteriosus using controlled-release coils was performed in 16 patients weighing < 10 kg. No embolization occurred. Procedure-related complications occurred in 3 patients (18.8%): massive femoral hemorrhage in 1 and femoral artery thrombosis in 2. The ductus recanalized in 1 of them because of mechanical hemolysis caused by streptokinase treatment. This was the only patient who underwent another occlusion procedure. Complete occlusion was achieved in 7 patients (43.8%) immediately, in 13 (81.2%) the following day, and in all 15 patients who had completed the 6-month follow-up. During follow-up, flow velocities between the left and the main pulmonary arteries and between the descending and the ascending aortae did not differ significantly. Flow velocity was > 2 m·sec−1 in 3 patients in the left pulmonary artery and in 1 in the descending aorta. Protrusion of the coil was seen in 3 of these patients. Flow velocity was also high in the main pulmonary artery in the 4th patient. In conclusion, coil occlusion of ductus arteriosus is feasible in the small child, but no more than half a loop of the coil should be left at the pulmonary site. High flow velocity does not always mean obstruction.

Left pulmonary artery (LPA) surgical arterioplasty done for juxtaductal pulmonary artery coarctation is a challenging technique that has often produced unsatisfactory outcomes because of poor outcome later and incomplete understanding of the evolution of structural changes in these vessels. We report a unique technique for LPA plasty involving main pulmonary artery (MPA) swing back, in a toddler who presented with history of increased work of breathing, cyanosis and failure to thrive since birth, where the MPA was detached and was swung back cranially to be anastomosed to LPA. This technique can be done, especially in univentricular heart (future Fontan candidate), since MPA needs to be interrupted. The patient had heterotaxy syndrome, left atrial isomerism, hypoplastic pulmonary valve with severe sub-valvar stenosis, duct dependent pulmonary circulation, good sized confluent branch pulmonary arteries with LPA narrowing at ductal insertion site, interrupted IVC with hemiazygous continuation and left SVC draining into coronary sinus. Initially underwent right modified Blalock taussig (BT) shunt, atrial septectomy, LPA plasty and PDA ligation at 6 months of age. Upon follow up after a year, diagnostic angiogram confirmed good flow in BT shunt and LPA re-stenosis with malpositioned great arteries. Redo sternotomy and Kawashima procedure was performed. BT shunt and MPA stump were divided. To conclude, the detached MPA segment was swung cranially and anstomosed to LPA (end to end) inferiorly and left SVC-LPA anstomosed superiorly onto this by end to side fashion. The early outcome was satisfactory, however long-term outcome needs to be followed up

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.
