Prolonged luminal narrowing of internal mammary artery graft after percutaneous transluminal angioplasty.
The authors describe a case with an internal mammary artery (IMA) graft that demonstrated prolonged, but reversible, luminal narrowing persisting > twenty-four hours following percutaneous transluminal angioplasty. Luminal narrowing disappeared spontaneously, however, at the time of follow-up angiography one week after the angioplasty. Since haziness at the dilation site had been shown on preprocedural angiogram, suggestive of intraluminal thrombus, this phenomenon may be attributed to either prolonged vasospasm or distal embolization of the IMA graft.
