Serial optical coherence tomography assessments at 2- and 4-month follow-up after paclitaxel-eluting stenting of the superficial femoral artery

A 71-year-old man underwent endovascular therapy (EVT) with a paclitaxel-eluting stent in superficial femoral artery (SFA). Optical coherence tomography (OCT) of SFA at 2 months after EVT revealed that several struts were not covered with neointima. Moreover, some mural thrombi were detected within the stent. Although OCT revealed that the frequency of stent strut coverage was improved at the 4-month follow-up, uncovered stent strut still remained and some mural thrombi were observed within the stent even at 4 months after EVT. This is the first report to demonstrate the vascular response after paclitaxel-eluting stent placement for the lesion using serial OCT examinations. © 2014, Japanese Association of Cardiovascular Intervention and Therapeutics.
