Summary
This study presents an emergency endovascular technique for thoracoabdominal aortic aneurysm (TAAA) using a modified device, enabling rapid treatment for patients unsuitable for open repair. This approach successfully preserved visceral artery flow and excluded the aneurysm.
Area of Science:
- Vascular Surgery
- Endovascular Interventions
- Aortic Aneurysm Repair
Background:
- Customized branched or fenestrated devices are established for elective thoracoabdominal aneurysm (TAAA) repair.
- Device customization is time-consuming, causing treatment delays exceeding one month.
Observation:
- An 80-year-old patient with TAAA presented with abdominal pain and refused open repair.
- An emergency endovascular treatment was performed using a modified Gore C3 Excluder device.
Findings:
- The modified device incorporated branches to facilitate emergency endovascular TAAA treatment.
- The technique successfully preserved visceral artery flow and excluded the aneurysm.
Implications:
- This novel technique offers a viable alternative for emergency TAAA management.
- It enables timely endovascular repair, avoiding delays associated with device customization.
- This approach is crucial for patients who are not candidates for open surgical repair.

Aneurysm management involves either conservative medical therapy or surgical intervention, depending on the size and symptoms of the aneurysm. Conservative management is generally reserved for smaller, asymptomatic aneurysms, while larger or symptomatic aneurysms often necessitate surgical repair.Conservative Medical TherapyFor small, asymptomatic aneurysms, particularly abdominal aortic aneurysms (AAA) less than 5.5 centimeters in diameter, conservative medical therapy is recommended.

Vigilant monitoring for aneurysm rupture is essential for patients undergoing aortic surgery.Preoperative Nursing ManagementContinuously monitor the patient for manifestations of aneurysm rupture, such as pallor, weakness, tachycardia, hypotension, abdominal, back, groin, or periumbilical pain, changes in consciousness, and a pulsating abdominal mass. Regularly assess the patient's peripheral pulses.Instruct the patient to consume a clear liquid diet the day before surgery and administer...
