Treatment of native coronary and saphenous vein graft aorto-ostial stenoses with balloon angioplasty is associated with lower procedural success rates and more complications compared with percutaneous transluminal coronary angioplasty of nonostial stenoses. A patient with totally occluded ostial left anterior descending artery at ostium following aortocoronary bypass developed ostial stenosis at the saphenous vein graft in the descending aorta. The aorto-ostial lesion of saphenous vein graft was successfully stented and was followed by retrograde dilatation of the left anterior descending artery, and the totally occluded ostial lesion was reopened. The ischemia was eliminated following the procedure.
与非开口处狭窄的经皮腔内冠状动脉成形术相比,球囊血管成形术治疗天然冠状动脉和隐静脉移植血管开口处狭窄的手术成功率较低,并发症更多。一名患者在主动脉冠状动脉搭桥术后,左前降支动脉开口处完全闭塞,降主动脉隐静脉移植血管出现开口处狭窄。成功对隐静脉移植血管的主动脉开口处病变进行了支架置入,随后对左前降支动脉进行逆行扩张,完全闭塞的开口处病变重新开通。术后缺血症状消除。
