Key result
Endoleaks occur in up to 30% of cases following endovascular repair of thoracic or abdominal aortic aneurysms, with diagnosis and treatment depending on the specific type among 5 categories.
This review summarizes the classification, imaging, and treatment options for endoleaks, a common complication occurring in up to 30% of TEVAR/EVAR procedures.
Endoleak type dictates post-EVAR/TEVAR management; review extends classification utility but leaves surveillance standardization open.
A common complication of endovascular repair of a thoracic or abdominal aortic aneurysm (TEVAR - EVAR) is an endoleak occurring in up to 30% of cases. Endoleak is defined as the persistence of blood flow outside the lumen of the endoprosthesis, but within the aneurysm sac and can be classified into 5 categories, depending on the blood flow into the aneurysm sac. Typical features of the different types of endoleaks are discussed as well as the imaging modalities to detect and classify an endoleak and the diverse (endovascular) treatment options.

Sam Heye (2013) conducted a review in Endoleaks after endovascular repair of thoracic and abdominal aortic aneurysms. Diagnosis and treatment of endoleaks was evaluated. Endoleaks occur in up to 30% of cases following endovascular repair of thoracic or abdominal aortic aneurysms, with diagnosis and treatment depending on the specific type among 5 categories.
