Successful Endovascular Stenting of a Bleeding External Iliac Vein Mycotic Aneurysm: A Case Report

Abstract Background: Mycotic aneurysms are rare vascular lesions, occurring in 0.6-2% of arterial aneurysms but with no reported venous cases. Venous aneurysms unrelated to an underlying infectious process have been previously described and are typically surgically repaired due to risk of thromboembolic events. Only a few reported cases have been successfully treated with endovascular repair. Case presentation: This case reports a bleeding external iliac vein mycotic aneurysm secondary to erosion of a chronic pelvic abscess, successfully treated with endovascular stenting. Conclusion: Venous aneurysms are uncommon vascular lesions which have historically been treated with open surgical repair. Given the lower degree of procedural morbidity, endovascular management of these lesions may be an effective option in the appropriate setting.
