Left Innominate Vein Aneurysm Finding during Pacemaker Lead Insertion

Abstract

Thoracic vein aneurysms are very rare vascular lesions, usually detected as incidental findings. We describe the case of a patient with an advanced atrioventricular block who underwent definitive pacemaker implantation. In order to explain the difficult advancement of a pacemaker lead, vein angiography was performed during the procedure and a large innominate vein aneurysm was observed. Successful lead placement was then performed without further complications. (PACE 2008; 31:627-629)

Diagnosing thoracic venous aneurysm: A contemporary imaging perspective

“…Etiology of the venous aneurysm has been largely unknown, with proposed mechanisms attributed to changes in vessel wall secondary to trauma, inflammation, and degeneration. [ 7 ] In our case, the histopathology of the resected dilated sac was normal, with no evidence of degeneration or inflammatory changes seen in vessel wall. Most of the mediastinal venous aneurysms are managed conservatively.…”

Brachiocephalic vein aneurysm: a systematic review of the literature

“…Two cases (17%) of antiplatelet therapy for brachiocephalic vein aneurysm have been described (15,38). One case was treated with ASA at 160 mg/day (15) the antiplatelet drug and dosing regimen for the other case is not available (38).…”

“…Two cases (17%) of antiplatelet therapy for brachiocephalic vein aneurysm have been described (15,38). One case was treated with ASA at 160 mg/day (15) the antiplatelet drug and dosing regimen for the other case is not available (38). One patient was lost to follow-up (38) and the other was on antiplatelet treatment for 15 years and remained asymptomatic (15).…”
