Abstract

Innominate vein aneurysms originating from the mediastinum are very rare. Previous treatments for this condition often required thoracotomy. We report a case of a 43-year-old male who presented a mediastinal mass by chest radiography. Contrast-enhanced CT and venography confirmed the diagnosis of left innominate vein aneurysm. The patient underwent endovascular treatment with stent placement and coil embolization of the left innominate vein. The patient remains well 18 months after surgery. The objective of this report is to discuss the diagnosis and endovascular treatment results of innominate vein aneurysm and to review the relevant literature to enhance and expand the pool of knowledge for this abnormality.

Keywords: Endovascular treatment; Innominate vein aneurysm; Literature review.

Post-stent placement angiogram showing that significant blood flow did not reappear in the lumen of the aneurysm (a); CT scan obtained 1 month post-treatment showing a complete thrombus within the aneurysm sac (b); CT scan obtained 3–6 months post-treatment showing an additional increase of blood flow in the aneurysm sac (c and d); complete thrombosis within the aneurysm and intraluminal thrombus around the stents found at 12 months (e); significant reduction of the aneurysm and a further increase in the intraluminal thrombus were observed at 18 months.
