Pseudocoartación aórtica en niños con ductus arterioso persistente: dos casos de una patología extremadamente infrecuente en menos de 48 horas / Aortic pseudocoarctation in children with persistent ductus arteriosus: two cases of an extremely uncommon pathology in less than 48 hours

Introducción: mientras la persistencia del ductus arterioso (PDA) es la cardiopatía congénita más frecuente, encontrar una pseudocoartación aórtica es muy poco frecuente y lo es más hallarlo en niños y solo hay unos cuantos casos reportados de este hallazgo en niños asociado a PDA. Material y Métodos: se describen los casos de 2 pacientes (1 con diagnóstico preoperatorio y otro sin él) con esta asociación: tanto los datos preoperatorios, los hallazgos transoperatorios, y su manejo trans y postoperatorio que operamos en menos de 48 horas.

Introduction: while the persistence of ductus arteriosus (PDA) is the most frequent congenital heart disease, finding an aortic pseudocoarctation is very rare and more find it in children and there are only a few reported cases of this finding in children associated with PDA. Material and Methods: we describe the cases of 2 patients (1 with preoperative diagnosis and another without it) with this association: the preoperative data, the transoperative findings, and their trans and postoperative management that we operated on in less than 48 hours.

Single-Stage Repair of Thoracic Aortic Aneurysm Associated with Aortic Stenosis and Pseudocoarctation by Means of the Clamshell Approach / 日本心臓血管外科学会雑誌

A 64-year old man was admitted to our hospital with a diagnosis of aortic stenosis. Pre-operative chest CT revealed pseudocoarctation of the aorta with a hypoplastic aortic arch, elongation and kinking of the aortic arch and proximal descending aorta. There was also a large aneurysm from the distal arch to descending aorta. We performed a single-stage repair of the aortic lesion from the ascending to the descending aorta with aortic valve replacement. For the surgical approach, transverse clamshell incision was applied safely. Concomitant aortic valve replacement in surgical repair of pseudocoarctation and thoracic aneurysm was rare, and clamshell incision seemed beneficial in such single-stage repair from the aortic root to the descending aorta.

Síndrome de Moebius, comunicación interventricular asociado a exposición prenatal a misoprostol / Moebius Syndrome, ventricular septal defect due to prenatal exposure to misoprostol

Introducción: El síndrome o secuencia de Moebius se caracteriza por la afectación del nervio facial y nervio abducens y puede estar asociado a defectos congênitos orofaciales y de las extremidades. Adicionalmente en las dos últimas décadas se han reortada una posible asociación con exposición prenatal a misoprostol. Objetivo: Presentar un caso de síndrome de Moebius con cardiopatía compleja (comunicación interventricular y pseudocoartación de aorta) asociado a exposición prenatal a misoprostol. Caso clínico: Paciente de 5 años quien consulta por antecedente de retardo en el desarrollo psicomotor, anomalías craneofaciales, cardiacas y de las extremidades, con antecedente de exposición prenatal a misoprostol, a quien se le diagnóstica síndrome de Moebius. Conclusiones: Aunque la etiología de este síndrome no es clara, un mecanismo fisiopatológico involucrado es el de la hipoxia que puede ser secundario a la exposición prenatal a misoprostol.

Introduction: Moebius syndrome/sequence is characterized by facial and abducens nerve damage and may be associated with congenital orofacial and limb defects. Additionally, in the last two decades, a possible association with prenatal exposure to misoprostol has been reported. Objective: To present a case of Moebius Syndrome with complex heart disease (ventricular septal defect and pseudocoarctation of the aorta) associated with prenatal exposure to misoprostol. Case report: A 5 year old patient diagnosed with Moebius Syndrome who consulted specialists due to psychomotor retardation, craniofacial, heart and limb defects, and with a history of prenatal exposure to misoprostol is presented. Conclusions: Although the etiology of this syndrome is not clear, hypoxia is a pathophysiological mechanism involved, which can be secondary to prenatal exposure to misoprostol.

Pseudocoarctation of the Aorta Associated with the Anomalous Origin of the Left Vertebral Artery: a Case Report

Pseudocoarctation of the aorta is a rare congenital anomaly of the aortic arch, and it has been described as an elongation of the aortic arch with "kinking" at the level of the ligamentum arteriosum without a pressure gradient across the lesion. The treatment for this condition is controversial. We report here on an unusual case of pseudocoarctation of the aorta associated with the anomalous origin of the left vertebral artery and we include a review of the medical literature.
