Abstract

The number of patients treated with abdominal aortic aneurysm (AAA) increased considerably in the last decades. Even though open surgery remains the gold standard for AAA treatment, endovascular techniques like Chimney grafts (CGs) showed to be reliable to treat patients with contraindications for conventional surgery and hostile neck aneurysms.
CGs are off-the-shelf stents which are accessible and useful for urgent/emergent cases.
This work reports a case of a 67 years-old caucasian male with a symptomatic infrarenal aortic aneurysm having a 2.5mm short neck and a maximum diameter of 67 mm. Due to patient comorbidities and after ruling out other causes for the pain, he was treated in urgency with chimney technique to prevent rupture.
