[Endovascular treatment of descending aortic dissection (type B)]

Area of Science:

• Cardiovascular Surgery
• Vascular Medicine
• Interventional Radiology

Background:

• Aortic dissection is a life-threatening condition with potential for rupture and fatal complications like ischemia.
• Type A aortic dissection typically requires open surgery, while Type B is managed medically unless complicated.
• Complicated Type B aortic dissection presents a surgical challenge, with stentgraft placement emerging as a viable option.

Observation:

• The patient presented with Type B aortic dissection, marked by rapid expansion and peri-aortic leakage.
• The dissection involved the descending aorta, necessitating urgent intervention.
• The clinical presentation indicated a high risk of rupture or further ischemic complications.

Findings:

• Successful treatment of Type B aortic dissection with thoracic aortic stentgraft placement.
• The stentgraft effectively excluded the dissected segment and controlled the leakage.
• The procedure was performed in a hybrid operating room, integrating surgical and interventional radiology capabilities.

Implications:

• Thoracic aortic stentgraft placement is an effective alternative to open surgery for complicated Type B aortic dissection.
• Hybrid operating rooms facilitate complex endovascular procedures for aortic diseases.
• This approach may improve outcomes and reduce morbidity in patients with complex aortic dissections.
