Endovascular treatment of aorta-iliac arterial pseudoaneurysm caused by Brucella.

ABSTRACT

We aimed to analyze the feasibility of endovascular treatment for brucellosis-related aorta-iliac artery pseudoaneurysm. We did a statistical analysis that among the 11 cases, the thoracic aorta was involved in 3 cases, the abdominal aorta was involved in 6 cases, and the iliac artery was involved in 2 cases. Five patients had a history of contact with cattle and sheep, 3 had a history of drinking raw milk, 10 patients had a fever before the operation, and 11 patients had positive serum agglutination test. Blood culture was positive in 2 patients. All patients were given anti-brucellosis treatment immediately after diagnosis. One died of aortic rupture 5 days after emergency endovascular gastrointestinal bleeding. Endovascular-covered stent implantation and active anti-brucellosis therapy were used to treat 10 patients. The follow-up period was 8 years without aortic complications or death for all patients. We think early diagnosis and a combination of anti-brucellosis drugs and endovascular therapy may be the first choice for treating the pseudoaneurysm caused by Brucella.
