Coronary Ostial Patch Angioplasty with Femoral Artery in Takayasu Arteritis.

Abstract Takayasu arteritis (TA) occasionally involves the coronary ostium leading to myocardial ischemia. Although surgical coronary ostial angioplasty is desirable for the ostial stenosis, the patch materials and long-term results are controversial. We have used femoral artery (FA) as a patch material for coronary ostial angioplasty in three TA patients. Coronary ostial enlargement with longitudinal incision and following rectangular-shaped FA patch augmentation was made to extend the narrowing coronary ostium. In all patients, coronary ostial stenosis was successfully repaired. Ostial angioplasty using FA patch would be a reasonable surgical strategy to treat coronary ostial stenosis in TA. Takayasu arteritis (TA) is a non-specific inflammatory disease of unknown etiology and commonly associated with resultant luminal narrowing and TA occasionally involves coronary ostium [1]. Although surgical coronary ostial angioplasty is desirable for the ostial stenosis without distal coronary lesion, the patch materials and long-term results are controversial. We have previously reported a case of coronary ostial angioplasty with superficial femoral artery (SFA) in TA [2] and obtained splendid long-term results, since then we applied this method for another two patients.
