The CERAB technique: tips, tricks and results

Area of Science:

• Vascular Surgery
• Endovascular Interventions
• Aortic Disease Treatment

Background:

• Extensive aortoiliac and juxtarenal occlusive disease present significant treatment challenges.
• Traditional surgical options and other endovascular techniques have limitations in managing complex lesions (TASC II C&D).
• Preservation of visceral arteries is crucial in treating these conditions.

Purpose of the Study:

• To provide an overview of recent in vitro and in vivo study results for the CERAB and C-CERAB techniques.
• To detail tips and tricks for successful recanalization and revascularization in complex cases.
• To evaluate the safety, efficacy, and outcomes of CERAB and C-CERAB for aortoiliac and juxtarenal disease.

Main Methods:

• Literature review of the last 5 years on endovascular treatment of TASC II C&D aortoiliac/juxtarenal lesions.
• Retrospective analysis of specialized techniques for interventional recanalization.
• In vitro and in vivo study data analysis for CERAB and C-CERAB techniques.

Main Results:

• CERAB configuration demonstrates significant benefits with excellent 1- and 2-year patency rates and low mortality/morbidity.
• C-CERAB variant shows 100% technical success, proving feasible and safe for juxtarenal/aortic occlusive disease with visceral artery preservation.
• Both techniques offer anatomical and physiological reconstruction of the aortic bifurcation.

Conclusions:

• CERAB and C-CERAB techniques are safe, feasible alternatives with promising results for extensive aortoiliac occlusive disease.
• These endovascular approaches may alter future treatment algorithms, serving as valid alternatives to surgery and kissing stents.
• Further research is needed on cost-effectiveness, patient selection, technique optimization, and medical support.
