A double aortic arch is a relatively uncommon anomaly occasionally associated with congenital heart disease or the chromosome 22q11 deletion. We report a case of prenatal diagnosis of a double aortic arch in which the sonographic features in the 3-vessel and trachea view are highlighted. A PubMed-based search was made to retrieve all cases of prenatal diagnosis of double aortic arch. A total of 13 articles and 35 cases were found. The average gestational age at diagnosis was 29 weeks. Six cases had associated cardiac anomalies. Only 1 case had the 22q11 deletion, showing extracardiac anomalies without cardiac defect. The postnatal evolution was characterized by symptoms of tracheoesophageal compression in 72.4% of the cases. Detection of a double aortic arch should be followed by a thorough fetal scan and echocardiography, and a chromosomal study should be considered when the sonographic findings are consistent with the 22q11 deletion.

Hybrid repair of complex aortic arch disease typically requires aortic debranching to create a proximal landing zone for completion arch endografting. Despite advances in endograft technology, physician-modified endografting may be required to customize a prosthesis for challenging anatomy. We present a case of a complex distal arch aneurysm after a prior coarctation repair with a pediatric interposition graft several decades earlier, treated with hybrid repair by double transposition for arch debranching and physician-modified arch endografting for complete aneurysm exclusion.

According to the Japanese Association for Thoracic Surgery annual surgery survey, the number of aortic surgery has been increasing constantly in the last two decades, with the rates approximately doubling in each decade (5,167, 11,956, and 22,708 cases in 1999, 2009, and 2019, respectively). In 2019, aortic surgery was performed for 11,036 (49%) nondissecting unruptured aneurysm, 730 (3%) ruptured aneurysm, 6,351 (28%) acute type A aortic dissection, 1,412 (6%) chronic type A aortic dissection, 2,385 (11%) acute type B aortic dissection, and 703 (3%) chronic type B aortic dissection cases. The outcomes have been improving annually.

Objective: Iron supplementation may reduce postoperative anemia, blood transfusions, and infections in patients undergoing surgery. We sought to assess efficacy and safety of prophylactic intravenous iron supplementation in patients without anemia undergoing cardiac surgery.

Methods: In this investigator-initiated industry-sponsored single-center randomized double-blind parallel group trial, we enrolled patients undergoing coronary bypass, aortic or mitral valve or ascending aortic surgery who fulfilled prespecified iron blood test safety criteria.

Double outlet right ventricle (DORV) is a rare congenital heart defect where both the aorta and pulmonary artery originate from the right ventricle, often accompanied by additional cardiac anomalies to mitigate circulatory imbalance, though such compensations usually fail. We report a 15-month-old infant with recurrent respiratory infections and poor weight gain, referred for computed tomography angiography. Physical examination showed a small, non-syndromic infant with pallor, tachypnea, irritability, and finger clubbing.

Spinal cord ischemia and injury pose significant challenges in spinal surgery and traumatic events. Cerebrospinal drains are considered a potential intervention to mitigate these risks, although their efficacy and safety are uncertain. We conducted a comprehensive systematic review and meta-analysis to evaluate the efficacy and safety of cerebrospinal drains in preventing and managing spinal cord ischemia and injury.
