Giant coronary aneurysm management with Viabahn covered stent
چکیده انگلیسی
A 68 year old female patient underwent coronary artery bypass surgery (CABG) 1 year previously. At that time she had a giant coronary artery aneurysm (CAA) of the proximal right coronary artery and severe 3 vessel disease including a severe ostial right coronary artery stenosis, severe stenosis of the proximal and mid left anterior descending artery (LAD) and a totally occluded left circumflex artery. She underwent CABG including left internal mammary artery to LAD, aorto-saphenous venous graft (ASVG) to posterior descending artery and ASVG sequential to the first diagonal and obtuse marginal branch. Subsequent computed tomography and invasive angiography demonstrated increasing size of the aneurysm (from 42 by 37 mm to 50 by 42 mm) which was now fed retrograde via the graft to the posterior descending artery in addition to being fed antegrade by the native vessel through a high grade stenosis. Percutaneous covered stent insertion was planned. The aneurysm was traversed with a guide wire, but passage of Viabahn covered stents was difficult due to the 8 Fr guide catheter and the bulky and rigid structure of the Viabahn stent. Using a distal anchoring technique and dual guide catheters, successful passage of two Viabahn stents (two of 5 by 50 mm) was accomplished. The technique utilized is described.
