Abstract

Few cases of aortocoronary saphenous vein (SV) graft aneurysm have been reported. These have been limited primarily to pseudoaneurysms occurring at either the proximal or distal anastomosis, although at least 6 cases of true aneurysmal change of the vein conduit itself have been reported in English.1–5 This report reviews an unusual case of acute rupture of an autogenous SV graft aneurysm, which presented initially as acute right hemothorax after a brief period of cardio-pulmonary resuscitation.

    The cause of SVG aneurysm after CABG remains unclear from the published reports. Suggested causes include systemic hypertension, infection (mycotic),5 poor vein quality or varicosity at the time of the first operation, and poor handling of the vein.6,7 Atherosclerosis is an important underlying pathologic mechanism.

    However, in the present cases, no clinical signs of local or systemic infection were observed. There are some reports of cases of aneurysmal change in the vein graft in the coronary artery after bypass grafting.3–5 According to these reports, the period between initial surgery and diagnosis of an aneurysm was between 4 and 6 months, and the authors speculated that the cause of aneurysmal change could be an inherent weakness of the venous wall or injury at the time of harvesting.

    This complication was first reported in 1975 [1]. Severe SVG dilatation within arterialized autologous veins can lead to many complications, including fistulas, compression of the right atrium or superior vena cava or pulmonary artery, rupture, and death [2–4]. Most authors refer to this as an aneurysm or pseudoaneurysm, if there is no pathological tissue.

    SVG aneurysms may be noted incidentally as a hilar or mediastinal mass on imaging [6]. Clinical sequelae may include thrombotic emboli producing myocardial ischaemia [2], compression of the right atrium [7], pulmonary artery or superior vena cava [8–11], arrhythmias [7] and rupture [4,10,12–15] with haemothorax or cardiac tamponade [14]. Fistulae between SVGs and cardiac chambers are very rare.
