Vascular ring anomaly with a right patent ductus arteriosus and a left aortic arch in a juvenile cat

Abstract

This paper reports the clinical findings and surgical treatment of feline right patent ductus arteriosus (RPDA) with a left aortic arch. A two-month-old female Maine Coon was referred for an investigation of regurgitation after weaning. RPDA with a left aortic arch was diagnosed based on the echocardiographic and computed tomography (CT) findings. A right-fourth intercostal thoracotomy was found to be an appropriate approach to the duct. Preoperative diagnosis is crucial and diagnostic imaging, including radiography, echocardiography, and cardiac CT examination, is essential for determining if the aortic arch is right or left.

A case report of patent ductus arteriosus in a Brazilian longhair female kitten

“…3,9 In this case report, the Doppler study and color flow mapping indicate continuous turbulent flow in the pulmonary artery, characterizing the persistence of patent ductus arteriosus. 10,11 Treatment consists of surgical correction, an efficient and safe procedure in up to 95% of cases. Among the complications associated with surgical correction of the patent ductus arteriosus, rupture of the ductus arteriosus may occur during dissection, infection, pneumothorax, cardiac arrhythmia, cardiac arrest, heart failure, thrombosis, pulmonary hypertension, and recanalization in cases of recurrence.…”
