A ruptured thoracoabdominal aortic aneurysm managed endovascularly using the telescoping chimney technique

Area of Science:

• Vascular Surgery
• Endovascular Techniques
• Aortic Aneurysm Repair

Background:

• Endovascular repair of aortic aneurysms often requires adequate proximal and distal landing zones.
• Techniques like chimney, top-fenestration, and snorkel grafts extend the proximal landing zone.
• The periscope technique has been described for extending the distal landing zone.

Observation:

• A patient with a ruptured Crawford type III thoracoabdominal aortic aneurysm presented with pre-existing renal failure and an occluded superior mesenteric artery.
• This complex anatomy posed significant challenges for standard endovascular repair.

Findings:

• The study successfully employed an extended chimney technique, termed the "telescoping technique," to manage the aneurysm.
• This innovative approach allowed for successful endovascular repair despite the challenging anatomical features.

Implications:

• The telescoping technique represents a viable and effective strategy for treating complex thoracoabdominal aortic aneurysms, particularly in patients with short proximal necks.
• This technique may expand endovascular treatment options for high-risk patients with challenging aortic pathologies.
• Further research is warranted to evaluate the long-term outcomes and applicability of the telescoping technique.
