Acute symptomatic abdominal aortic aneurysm secondary to endovascular stent graft associated type II endoleak.
Endovascular abdominal aneurysm repair (EVAR) is popular because of its low invasiveness and feasibility for high-risk patients. Endoleak is common after EVAR and is characterized by blood flow within the aneurysm sac but outside the stent graft. Type II or collateral endoleak commonly results from retrograde filling of the aneurysm from collateral visceral vessels, lumbar, inferior mesenteric, accessory renal or sacral arteries. Collateral leaks are generally thought to be benign and over half of the early leaks will seal spontaneously. Sporadically, collateral endoleak could lead to aneurysm sac pressurization and place the patient at ongoing risk of rupture. Herein, we report an uncommon case of early post-stent graft placement symptomatic abdominal aortic aneurysm associated with type II endoleak.
