A 66-year-old man with an abnormal electrocardiogram during a health examination sought evaluation at the cardiology department. Contrast-enhanced computed tomography (CT) revealed the presence of aneurysms associated with aortopulmonary and left coronary artery-pulmonary artery fistulas. One of the identified aneurysms measured 20 mm. The patient was then referred to our department for surgical intervention. Although the patient was asymptomatic, surgery was planned due to the risk of rupture. Initially, coil embolization was performed to address the aortopulmonary fistula, which was followed by a median sternotomy. Intraoperatively, multiple tortuous abnormal vessels connecting both coronary arteries to the pulmonary artery were observed, along with aneurysms at the base of the pulmonary artery. The aneurysms were excised under cardiopulmonary bypass, and the opening of the pulmonary artery fistula was closed. Subsequent coronary angiography during surgery and postoperative cardiac CT confirmed the complete resolution of the abnormal vessels and aneurysms. The patient had an uneventful postoperative course and was discharged. We present the case of a patient with aneurysms associated with thoracic aortopulmonary and left coronary artery-pulmonary artery fistulas and review the relevant literature. The case was managed with a single-stage surgery involving coil embolization, aneurysm resection, and fistula closure.

We describe the case of a 1-year and 7-month-old girl who was born at 36 weeks and 6 days of pregnancy weighing 1,351 g. In addition to the diagnosis of Cornelia de Lange syndrome and Tetralogy of Fallot, we confirmed shunt blood flow from the lesser curvature of the aortic arch to the main pulmonary artery. Thus, we additionally diagnosed ectopic patent ductus arteriosus (PDA). Ultrasonography showed interruption and retrograde flow of the diastolic blood flow in the anterior cerebral artery. Therefore, we made a diagnosis of blood stealing due to an ectopic PDA, and we performed surgical intervention via a median sternotomy at 25 days. When we ligated the shunt blood vessel, the percutaneous oxygen saturation decreased from the high 90% range to the low 70% range, thus we temporarily released the ligation. We narrowed the ectopic PDA so that the percutaneous oxygen saturation could be maintained the high 80% range. Postoperative ultrasonography showed improvement of the pressure waveform in the anterior cerebral artery. After discharge, oxygen demand increased gradually with weight gain, and we performed intracardiac repair using a monocusp valve patch at 1 year and 7 months. We report a rare case of Cornelia de Lange syndrome wherein we achieved intracardiac repair of Tetralogy of Fallot after ectopic PDA banding in the neonatal period.

Objective:
To assess the noncontrast two-dimensional single-shot balanced turbo-field-echo magnetic resonance angiography (b-TFE MRA) features of the abdominal aortic aneurysm (AAA) status following endovascular aneurysm repair (EVAR) and evaluate to detect endoleaks (ELs).
Materials and Methods:
We examined four aortic stent-grafts in a phantom study to assess the degree of metallic artifacts. We enrolled 46 EVAR-treated patients with AAA and/or common iliac artery aneurysm who underwent both computed tomography angiography (CTA) and b-TFE MRA after EVAR. Vascular measurements on CTA and b-TFE MRA were compared, and signal intensity ratios (SIRs) of the aneurysmal sac were correlated with the size changes in the AAA after EVAR (AAA prognoses). Furthermore, we examined six feasible b-TFE MRA features for the assessment of ELs.
Results:
There were robust intermodality (r = 0.92–0.99) correlations and interobserver (intraclass correlation coefficient = 0.97–0.99) agreement. No significant differences were noted between SIRs and aneurysm prognoses. Moreover, “mottled high-intensity” and “creeping high-intensity with the low-band rim” were recognized as significant imaging findings suspicious for the presence of ELs (p < 0.001), whereas “no signal black spot” and “layered high-intensity area” were determined as significant for the absence of ELs (p < 0.03). Based on the two positive features, sensitivity, specificity, and accuracy for the detection of ELs were 77.3%, 91.7%, and 84.8%, respectively. Furthermore, the k values (0.40–0.88) displayed moderate-toalmost perfect agreement.
Conclusion
Noncontrast MRA could be a promising imaging modality for ascertaining patient follow-up after EVAR.
