[MO-53] Detection of Ruptured Plaques in the Superficial Femoral Artery Using Angioscopy.
Little is known about the plaque characteristics of the superficial femoral artery (SFA) by angioscope observation. A 75-year-old woman had intermittent claudication of her left leg. Diagnostic angiography revealed severe stenotic lesion of left SFA, and subsequently endovascular treatment was performed. Angioscopic findings showed yellow plaques at mid portion of SFA and dissection at proximal portion of SFA. We performed balloon dilation for 10 minutes and used drug coated balloon after we confirmed that no severe flow limitation. Final angioscopic findings of the target lesions showed that the particle of the drug attached every to the intima, clot attached partly, the dissection was remained. However, particularly interesting views are to have revealed ruptured plaques in the proximal lesion which was not a target lesion. The characteristic views that blood gushed out of the lesion had few reports, and we named the phenomenon ‘erupting ulcer (EU)’ so that a volcano totally erupted. It will be necessary to repeat examination in future what kind of clinical significance this EU has.
