Radiological follow-up after endovascular aortic repair - review of surveillance modalities.

Abstract

Objective: Aim: This review aims to present diagnostic modalities suitable for monitoring patients after endovascular aortic repair.

Patients and methods: Materials and Methods: A literature search was conducted across electronic databases from January 2024 to May 2025 using a combination of keywords and Boolean operators.

Conclusion: Conclusions: While computed tomography angiography remains the reference standard for monitoring after endovascular aortic repair, with 92% sensitivity for endoleak detection, magnetic resonance imaging and ultrasonography offer viable alternatives that eliminate radiation exposure and may reduce contrast agent requirements. Magnetic resonance imaging detects twice as many endoleaks as computed tomography angiography, whereas contrast-enhanced duplex ultrasonography achieves 98% sensitivity and 88% specificity. Treatment of abdominal aorta aneurysm with endovascular aortic repair offers a significant opportunity for a carefully selected patient population. The selection of surveillance modalities should be tailored to individual patient characteristics.
