Utility of Intra-operative Cone Beam Computed Tomography in Endovascular Treatment of Aorto-iliac Occlusive Disease.

Summary, in English

Endovascular treatment of aorto-iliac occlusive disease (AIOD) is well established, but to maintain long-term patency, secondary interventions are common. Multiple stents and iliac artery tortuosity often make it difficult to evaluate stent compression intra-operatively and this might be a cause for later failure. Completion angiography (CA) and pressure gradient (PG) measurement are often used to assess the final intra-operative result. The purpose of this study was to evaluate the role of intra-operative cone beam computed tomography (CBCT) to optimize the primary operation results.
