Introduction: Severe ilio-femoral occlusive disease can limit the endovascular treatment of aorto-iliac aneurysms. In high surgical risk patients, inventive and staged hybrid interventions can be the answer to achieve definitive treatment.
Clinical Case: A 68-year-old male, with multiple comorbidities, presented with simultaneous occurrence of bilateral common iliac aneurysms and severe ilio-femoral occlusive disease associated with right critical limb-threatening ischemia. In order to exclude the iliac aneurysms, preserve pelvic flow and revascularize the threatened limb we decided for a three-staged hybrid intervention. First, we began with a right external iliac angioplasty with femoral endarterectomy to create adequate arterial access. In a second intervention, we implanted a bifurcated aortoiliac endograft through this access. In order to prevent pelvic ischemia, contralateral leg outflow was directed to the left internal iliac artery with a combination of self-expandable and balloon-expandable covered stents. Finally, a right femoro-posterior tibial artery bypass completed the revascularization. At 1,5-year follow-up, no complications are reported and the patient is asymptomatic.
Conclusion: In patients with poor medical condition and complex aorto-iliac aneurysmal and occlusive disease, a staged hybrid approach like the one described in this case-report can be feasible and associated with durable midterm patency and excellent clinical outcome.
