No statistically significant differences were found between the two endovascular approaches for pararenal aortic pathologies in terms of 30-day mortality, renal impairment, or endoleak. These findings support the assumption that chimney grafts may be a reliable alternative in the treatment of pararenal aortic pathologies.

Moderate-size CIA aneurysms (<30 mm) can be safely and effectively treated using the bell-bottom technique. The risk of distal type I endoleak is low. Iliac-related complications can be successfully treated by endovascular techniques.

Open surgery for common femoral artery stenosis is safe and effective in the long-term. Endovascular therapy will need to compete with these excellent results.

The 2-year outcome of our series underscores the value of infrapopliteal nitinol stent placement as a durable bailout treatment option in high-risk CLI patients with suboptimal angioplasty.
