A Unique Case of Middle Aorta Syndrome With a "Corkscrew" Descending Aorta

Area of Science:

• Cardiovascular Medicine
• Pediatric Cardiology
• Vascular Surgery

Background:

• Middle aortic syndrome (MAS) is a rare congenital anomaly characterized by the narrowing of the descending aorta.
• It often presents with severe, difficult-to-manage hypertension, particularly in pediatric patients.
• The underlying pathophysiology involves abnormalities in aortic development.

Observation:

• This report details a unique case of middle aortic syndrome exhibiting a distinct "corkscrew" configuration of the affected aortic segment.
• The patient presented with significant hypertensive complications secondary to the aortic anomaly.
• The unusual morphology posed diagnostic and therapeutic challenges.

Findings:

• Advanced imaging modalities, such as computed tomography angiography (CTA) or magnetic resonance angiography (MRA), are essential for accurate diagnosis of MAS.
• The "corkscrew" appearance represents a specific, albeit rare, morphologic variant of this condition.
• Surgical intervention, including aortic reconstruction, is often necessary for definitive management.

Implications:

• Early and accurate diagnosis through advanced imaging is critical for timely surgical intervention in middle aortic syndrome.
• Effective management can prevent severe, long-term hypertensive complications and end-organ damage.
• This case underscores the importance of considering rare vascular anomalies in the differential diagnosis of pediatric hypertension.
