INTRODUCTION: The descending thoracic aorta (DTA) has been used as inflow mostly as a secondary option for revascularization after either graft failure/infection or other intra-abdominal pathologies contraindicating a standard abdominal aortic approach. The objective of this review is to summarize current evidence on the use of this inflow site for revascularization procedures. METHODS: A comprehensive electronic literature search was performed, using PubMed and Embase databases. All literature published in English in the last 30 years was considered. The main goal was to assess the feasibility and practicality of implementing this approach in cases of severe and complex aortoiliac lesions. RESULTS: Our review comprised 11 articles. DTA has been used predominately as a secondary option. The 30-day mortality rate was 4% (9/222). Secondary graft patency at 5-years was generally high across all studies. The use of DTA as inflow has been shown to be a safe and effective option for aorto-iliac reconstruction. CONCLUSION: DTA can be used safely as an inflow for lower-limb revascularization and it remains an important tool in the vascular surgeon's armamentarium.
