An operative case of pseudocoarctation with chronic dissection

Area of Science:

• Cardiovascular Surgery
• Vascular Surgery
• Aortic Diseases

Background:

• Pseudocoarctation of the aorta is a rare congenital or acquired condition characterized by aortic arch narrowing.
• Chronic aortic dissection, particularly in the context of pseudocoarctation, presents unique diagnostic and therapeutic challenges.
• Surgical management for this specific pathology is infrequently documented.

Observation:

• A 47-year-old male with hypertension presented with a prominent aortic knob on chest X-ray.
• Computed tomography angiography revealed severe proximal descending aorta flexion with chronic type B dissection localized to this region.
• The patient exhibited signs suggestive of aortic arch pathology.

Findings:

• The patient was diagnosed with chronic dissection associated with distal aortic arch pseudocoarctation.
• Surgical intervention involved graft replacement of the distal aortic arch.
• The procedure successfully addressed the complex aortic pathology.

Implications:

• This case underscores the importance of considering pseudocoarctation in the differential diagnosis of aortic abnormalities.
• Successful surgical management demonstrates a viable therapeutic strategy for this rare condition.
• Further case reports and studies are needed to refine surgical approaches for chronic dissection of distal aortic arch pseudocoarctation.
