Navigating complexity: ruptured pulmonary artery dissection originating from type B aortic dissection via a...

Area of Science:

• Cardiovascular Medicine
• Thoracic Surgery
• Vascular Imaging

Background:

• Pulmonary artery dissection (PAD) is a rare and life-threatening condition.
• Ruptured PAD can arise from aortic dissection, posing significant diagnostic and therapeutic challenges.

Purpose of the Study:

• To report a unique case of ruptured left pulmonary artery dissection.
• To highlight the successful endovascular treatment of a complex cardiovascular emergency.

Main Methods:

• Presentation of a clinical case involving a 29-year-old male with ruptured left PAD.
• Successful treatment using thoracic endovascular aortic repair (TEVAR).

Main Results:

• The patient presented with symptoms of ruptured left PAD secondary to acute type B aortic dissection (aTBAD) via a persistent ductus arteriosus Botalli (PDA).
• TEVAR successfully addressed the primary aortic entry, leading to complete symptom resolution and observed vascular remodeling.
• This approach resolved the cardiovascular emergency without further intervention.

Conclusions:

• This case demonstrates a rare etiology of PAD originating from aTBAD.
• TEVAR targeting the primary aortic pathology is an effective treatment for this rare condition.
• Interdisciplinary collaboration is crucial for managing complex cardiovascular emergencies.
