[A case of coronary artery bypass grafting using patch mounted graft technique for aortitis syndrome with left
1Department of Cardiovascular Surgery, Hiraka General Hospital, Yokote, Japan.
Insights
Coronary artery bypass grafting (CABG) using a patch-mounted graft technique effectively treated aortitis syndrome with coronary ostial stenosis. This method demonstrated excellent graft patency one year post-operation, reducing late occlusion risks.
Area of Science:
- Cardiovascular Surgery
- Vascular Surgery
- Thoracic Surgery
Background:
- Aortitis syndrome can cause coronary ostial stenosis, necessitating surgical intervention.
- Coronary artery bypass grafting (CABG) is a standard treatment, but late graft occlusion remains a concern, especially in aortitis patients.
Observation:
- A 36-year-old female with aortitis syndrome underwent CABG for left coronary ostial stenosis.
- The procedure involved anastomosing the left anterior descending artery to the left internal thoracic artery and the circumflex artery to a saphenous vein graft.
- A gelatin-sealed knitted Dacron graft patch was used for the proximal anastomosis to the ascending aorta to mitigate intimal proliferation.
Findings:
- Graft angiography at 40 days and one year post-CABG confirmed good patency of both the arterial and venous grafts.
- The patch-mounted graft technique proved effective in preventing late occlusion, a common complication in this patient population.
Implications:
- The patch-mounted graft technique is a suitable and potentially superior option for CABG in patients with aortitis syndrome.
- This approach may improve long-term outcomes by reducing the incidence of late graft occlusion due to intimal proliferation.
Abstract:
Coronary artery bypass grafting (CABG) was performed on a 36-year-old female for treatment of aortitis syndrome with left coronary ostial stenosis. The left anterior descending artery was anastomosed with the left internal thoracic artery. The circumflex artery was anastomosed with the saphenous vein. In the proximal anastomosis, the ascending aorta was sutured with a gelatin sealed knitted Dacron graft patch and anastomosed with the saphenous vein to prevent late occlusion due to intimal proliferation. Graft angiography 40 days and one year after the operation showed good patency of both grafts. Patch mounted graft technique seemed to be suitable for CABG in aortitis patients with the high incidence of late occlusion.
