Successful endovascular stenting of a bleeding external iliac vein mycotic aneurysm in an oncologic patient: 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. 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, in an oncologic patient without alternative therapeutic options. 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, particularly as a last resort in patients without surgical treatment options.

Open aneurysmorrhaphy for repair of a massive iliac vein aneurysm and review of the recent literature

“…Three patients were conservatively managed (11.5%), and 11 (42.3%), 3 (11.5%), and 9 (34.6%) underwent open, hybrid, or endovascular repair, respectively. 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 …”

“… 15 Several patients undergoing endovascular or hybrid repair (5 of 12; 41.7%) required reintervention or demonstrated stent thrombosis on follow-up imaging. 12 , 13 , 14 , 20 , 23 …”
