[Emergency stent placement after descending aortic replacement with chronic aortic dissection]

Area of Science:

• Cardiovascular Surgery
• Vascular Surgery
• Interventional Cardiology

Background:

• A 49-year-old male patient with a history of ascending aortic replacement for type A aortic dissection presented with asymptomatic chronic aneurysmal dissection.
• The patient underwent a descending aortic replacement for the chronic aneurysmal dissection.

Observation:

• Postoperatively, the patient developed renal dysfunction.
• Contrast-enhanced computed tomography revealed severe compression of the true lumen by a false lumen, leading to occlusion of the renal artery origins.

Findings:

• Emergency endovascular stent placement was performed to dilate the compressed true lumen.
• The procedure promptly resolved the renal ischemia, and the patient's postoperative course was uneventful.

Implications:

• Endovascular stent placement using a bare stent is a viable, less invasive, and prompt treatment option for renal ischemia secondary to aortic dissection.
• This approach can significantly improve outcomes in patients experiencing acute kidney injury following aortic dissection repair.
