Experience has shown that cerebral protection during carotid angioplasty and stenting is technically feasible and appears to be effective in preventing procedure-related neurologic complications. Further investigation is warranted.

In this model, intrasac pressures were significantly higher than systemic pressures in the presence of all endoleaks, even the smallest ones. Intrasac pressures higher than systemic pressure may pose a high risk for aneurysm rupture. Although patent side branches significantly reduce these pressures, the aggressive management of an endoleak should be pursued.

The efficacy and safety of carotid angioplasty and stenting with PAES are confirmed. This innovative protection device may prevent the debris released by angioplasty from entering the cerebral circulation. Further investigation is warranted.

The endoluminal approach of the diffusely atheromatous aorta (DAA) is an emerging tool to prevent further embolization. We treated one symptomatic patient with DAA. We designed a catheter with a balloon at the tip for occlusion of both common iliac arteries through which the antegrade flow was allowed by an iliac to femoral arterio-arterial shunt connected to an in-line filter. Filter wires were also placed in the superior mesenteric and both renal arteries' take-off, keeping their antegrade flow. The endograft was then introduced through these tubes. Endoluminal treatment of the primary source of atheromatous embolization is feasible, representing a new approach to be considered.
