Summary
Thoracic endovascular aortic repair for aortic arch aneurysms can lead to complications like stent graft collapse. This case highlights the need for vigilance and prompt intervention following such procedures.
Area of Science:
- Cardiovascular Surgery
- Vascular Surgery
- Medical Device Complications
Background:
- Saccular aortic arch aneurysms pose significant risks.
- Thoracic endovascular aortic repair (TEVAR) is a treatment option for aortic arch aneurysms.
- Complications following TEVAR require careful monitoring and management.
Purpose of the Study:
- To report a rare complication of TEVAR.
- To highlight the importance of early diagnosis and intervention for stent graft failure.
- To discuss management strategies for TEVAR-related complications.
Main Methods:
- A case report of a 69-year-old male patient.
- TEVAR with a zone 0 landing for a saccular aortic arch aneurysm.
- Postoperative computed tomography (CT) scan to diagnose stent graft collapse.
- Emergency surgical intervention including total arch replacement and stent graft removal.
Main Results:
- The patient developed diminished consciousness and lower limb paralysis 7 days post-TEVAR.
- CT scan revealed complete collapse of the thoracic stent graft.
- Successful emergency total arch replacement and stent graft removal were performed.
Conclusions:
- Stent graft collapse is a potential, serious complication of TEVAR.
- Prompt diagnosis and surgical intervention are crucial for managing TEVAR complications.
- Further research into TEVAR device integrity and long-term outcomes is warranted.

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.

01:25Aortic Regurgitation III: Medical Management
24
Aortic regurgitation (AR) is when the aortic valve does not close or seal properly, leading to backward blood circulation from the aorta into the left ventricle during diastole. Common causes of AR include rheumatic heart disease, congenital valve defects, and aortic root dilation. Managing AR requires a multifaceted approach to alleviate symptoms, preserve left ventricular function, and address the underlying cause of the regurgitation. Patients with symptomatic AR or significant left...

The thoracic section of the aorta begins at the T5 vertebra and extends to the T12 level at the diaphragm, initially progressing through the mediastinum to the left of the spinal column. Throughout its course in the thoracic segment, the thoracic aorta emits various offshoots known collectively as visceral and parietal branches. The branches that predominantly supply blood to visceral organs are termed visceral branches and include bronchial, pericardial, esophageal, and mediastinal arteries,...
