RESUMO
Abdominal aortic aneurysm (AAA) is a common medical condition with the feared, and often fatal, complication of rupture. The risk of rupture has been well documented to correlate with aneurysm size. It is exceedingly rare for an AAA less than 5 cm to rupture. This case report demonstrates an asymptomatic 4.3 cm AAA that ruptured while admitted to the hospital with COVID-19 pneumonia. The patient was successfully managed with an endovascular aortoiliac stent graft. Although rare, in patients with small AAA, rupture must remain in the differential diagnosis in the setting of acute onset abdominal or back pain. Furthermore, when quickly recognized, these patients can be safely managed with an endovascular approach.

Aortoenteric fistula is a rare complication after endovascular stent grafting. In the present report, we have described the case of a 69-year-old man 3 years after endovascular repair of an abdominal aortic aneurysm who had presented with worsening back pain and fever. Computed tomography had demonstrated dilated bowel and a thickened aortic wall, with air foci within the native aneurysm sac. He underwent emergent right axillary-bifemoral bypass with explantation of the aortic endograft and primary repair of the duodenal fistula. Tissue cultures grew Streptococcus anginosus, Prevotella denticola, and Parvimonas micra, and he was discharged home with 6 weeks of intravenous ceftriaxone and oral metronidazole after an 18-day hospital admission.
