Giant aneurysm of saphenous vein graft to coronary artery compressing the right atrium

Aneurisma gigante de ponte de safena para coronária direita após angioplastia

“…Aneurysm of aortocoronary bypasses is a rare and potentially fatal complication of coronary artery bypass grafting surgery [1][2][3][4] . Its true incidence is unknown and it is believed to be underestimated.…”

“…And despite some ambiguities in the literature, the first has a late presentation and involves the whole vessel wall, presenting as an enlargement of more than 1.5 times the normal size of the vessel 1,4 . On the other hand, the pseudo-aneurysm is not formed by all the structures of the vascular wall and it can occur earlier 7 , presenting usually near the proximal or distal anastomosis.…”

“…On the other hand, the pseudo-aneurysm is not formed by all the structures of the vascular wall and it can occur earlier 7 , presenting usually near the proximal or distal anastomosis. Several mechanisms are involved in the formation of true aneurysm, such as hyperlipidemia 1 , atherosclerosis, smoking, weakness of the venous endothelium (veins prone to varicose veins). In contrast, the problems with the surgical technique or vein preparation, trauma and infections are related to the pseudoaneurysma 4 .…”

Substantive incidental cardiac findings revealed by non-cardiac CT examination of the thorax

“…The distinction is academic as surgical resection and revascularisation are the preferred treatment for both. [3] Case 3…”

Aneurysm of a coronary vein graft

“…1 Aneurysms are often asymptomatic and detected incidentally on chest radiography, but may present with an acute coronary syndrome, heart failure, acute rupture or from local pressure complications. 2 Management strategies include ligation, coil embolisation and implantation of a covered stent.…”
