1Department of Surgery, University of Missouri, Columbia, MO.
Insights
Revascularizing the left subclavian artery during thoracic endovascular aortic repair is recommended to reduce stroke and spinal cord ischemia risks. This article reviews methods for preserving left subclavian artery flow in these procedures.
Area of Science:
- Vascular Surgery
- Cardiovascular Interventions
- Thoracic Aortic Disease
Background:
- Left subclavian artery (LSAA) revascularization during thoracic endovascular aortic repair (TEVAR) is a debated topic.
- Current evidence suggests LSAA revascularization may mitigate perioperative stroke, spinal cord ischemia, and upper extremity dysfunction.
- Optimal management strategies for LSAA coverage during TEVAR remain under investigation.
Purpose of the Study:
- To review traditional and novel techniques for LSAA revascularization during TEVAR.
- To discuss the benefits of preserving LSAA flow in TEVAR procedures.
- To provide an overview of current options for LSAA management.
Main Methods:
- Review of existing literature on LSAA revascularization and TEVAR.
- Description of established surgical and endovascular revascularization techniques.
- Presentation of emerging technologies and approaches for LSAA flow preservation.
Main Results:
- LSAA revascularization is associated with reduced risks of stroke and spinal cord ischemia.
- Various methods exist, ranging from traditional bypass to advanced endovascular techniques.
- The choice of method depends on patient anatomy and procedural complexity.
Conclusions:
- Preserving LSAA flow during TEVAR is increasingly favored to improve patient outcomes.
- A range of techniques are available, allowing for tailored approaches.
- Further research may refine indications and techniques for LSAA revascularization.
Abstract:
Left subclavian artery revascularization at the time of thoracic endovascular aortic repair has been the subject of discussion for over a decade. Contemporary viewpoints suggest that revascularization should be performed where possible to decrease the risk of perioperative stroke, spinal cord ischemia, and, to a lesser degree, loss of upper extremity function. In this article, we present traditional methods as well as descriptions of newer options and technology for preservation of left subclavian artery flow during thoracic endovascular aortic repair.
