Endovascular Treatment of a Mycotic Subclavian Artery Aneurysm Using Stent-graft

Abstract 

We report a case of an immuno-suppressed 49-year-old man with mycotic aneurysm of left subclavian artery. The aneurysm was diagnosed by computed tomography and digital subtraction angiography. Our choice for treatment was endovascular stent-graft implantation. After stent-graft implantation, type I endoleak was present because of the aneurysm had broad neck and, so, we implanted second stent-graft proximally to the first stent. The end of the procedure, there was a minimal type III endoleak into the aneurysm sac. The patient was well and free of symptoms after 1 week. A control CT angiography, after 5 months, showed a completely thrombosed aneurysm without an endoleak. Endovascular repair of a mycotic subclavian artery aneurysm may be an alternative to open surgery.
