Double aortic arch
Clinical Classification Guidelines
Inclusion Terms
- Vascular ring of aorta
Medical Intelligence & Overview
Double aortic arch is a rare congenital vascular condition where the aorta, the main artery carrying blood from the heart to the rest of the body, forms a ring around the trachea and esophagus. This ring, known as a vascular ring, can compress the airway and esophagus, leading to breathing and swallowing difficulties. Recognized under ICD-10 code Q25.45, this condition is usually diagnosed in infancy or early childhood but can sometimes remain undetected until adulthood. Proper understanding of its causes, symptoms, and treatment options is essential for managing the condition effectively.
Causes & Symptoms
Clinical Causes: Congenital malformation during fetal development, particularly during the transformation of the aortic arch arteries. Incomplete regression of certain embryonic vascular structures that typically disappear or remodel early in fetal development. Genetic factors that may influence cardiovascular development, although specific genetic causes are not well-established.
Key Symptoms: Difficulty breathing, especially during feeding in infants. Stridor — a high-pitched noise during breathing caused by airway compression. Swallowing problems or choking episodes. Persistent cough or recurrent respiratory infections. Cyanosis, or a bluish tint to the skin, particularly during exertion. Feeding difficulties and poor weight gain in infants.
Diagnostic & Treatment
Diagnosis Path: Echocardiography (ultrasound of the heart) to evaluate heart and major vessels. Chest X-ray to identify abnormal vascular shadows or patterns. CT angiography or magnetic resonance angiography (MRA) providing detailed images of the vasculature and confirming the presence of a vascular ring. Endoscopy may be used to assess airway compression if symptoms suggest tracheal involvement. Cardiac catheterization in some cases, to precisely delineate vascular anatomy.
Treatment Protocols: Surgical division of the smaller of the two arches forming the ring, often via a thoracotomy or minimally invasive techniques. Postoperative monitoring for airway and esophageal function. Additional supportive care for respiratory or feeding difficulties. Long-term follow-up to assess for residual or recurrent symptoms and manage complications.
