Revascularization options for left subclavian salvage during TEVAR.

Area of Science:

• Vascular Surgery
• Cardiovascular Interventions
• Thoracic Surgery

Background:

• Revascularization of the left subclavian artery is crucial during thoracic endovascular aortic repair (TEVAR) to maintain upper extremity perfusion.
• Traditionally, open surgical revascularization has been the standard approach for managing left subclavian artery issues in TEVAR.

Purpose of the Study:

• To review and compare available solutions for left subclavian artery revascularization in the context of TEVAR.
• To evaluate the evolving landscape of endovascular techniques versus established open surgical methods.

Main Methods:

• Comprehensive literature review of studies on left subclavian artery revascularization.
• Analysis of technical aspects and outcomes for both open surgical and endovascular approaches.
• Synthesis of current evidence regarding the efficacy and safety of different revascularization strategies.

Main Results:

• Open surgical revascularization remains a predominant technique with established results.
• Emerging endovascular revascularization techniques offer potential alternatives with promising early outcomes.
• The choice between open and endovascular revascularization depends on patient-specific factors and procedural complexity.

Conclusions:

• Both open and endovascular revascularization strategies have a role in managing the left subclavian artery during TEVAR.
• Advancements in endovascular technology may lead to increased utilization of these less invasive techniques.
• Further research is needed to fully elucidate the long-term comparative effectiveness of these approaches.
