Superior vena cava syndrome secondary to saphenous venous graft aneurysm with right atrial fistula

Abstract

Mega-aneurysms of saphenous vein grafts (SVGs) to coronary arteries are rare complications of bypass surgery. We report the development of superior vena cava syndrome secondary to an SVG mega-aneurysm with concomitant fistulous communication to the right atrium. Successful treatment was achieved by coil embolization and chronic anticoagulation.

Severe Dilatation of Saphenous Vein Grafts: A Late Complication of Coronary Surgery in Which the Diagnosis Is Suggested by Chest X-Ray

“…Our literature review identified 107 patients [1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30,31,32,33,34,35,36,37,38,39,40,41,42,43,44,45,46,47,48,49,50,51,52,53,54,55,56,57,58,59,60,61,62,63,64,65,66,67,68,69,70,71,72,73,74,75,76,77,78,79,80,81,82,83,84,85,86,87,88,89,90,91,92,93,94,95]. The demographic, clinical and pathological features are summarized in ...…”

Combined treatment of trans-catheter coil embolization and modified covered stent implantation for ruptured saphenous vein graft aneurysm in patient with recurrent congestive heart failure

“…Reported time interval of development of this complication is about 10-20 years postoperatively. Among them, the presence of a fistulous communication between the SVG aneurysm and one of the heart chambers is extremely rare and only 7 cases have been reported [1][2][3][4][5][6][7]. In six cases of them, the SVG aneurysms were connected to the right atrium, and in the seventh, it was connected to the To the best of our knowledge, this is the first report that the SVG aneurysm was connected to the LA.…”

Fistula From Aneurysmal Saphenous Vein Graft to Right Atrium Treated with Covered Stents

“…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][9][10][11], arrhythmias [7] and rupture [4,10,12-15] with haemothorax or cardiac tamponade [14].…”

“…Most reported cases have involved the right atrium [5,9,[16][17][18][19][20] and an adjacent right coronary artery (RCA) graft: communications with the right ventricle [ …”
