[Restenosis after coronary angioplasty].

Abstract

Angiography of 169 patients who had been treated successfully with PTCA showed restenosis in 61. Of these, 38 were successfully treated with a new PTCA, and six developed a new restenosis. Restenosis usually appears during the first four months after PTCA in vessels with a diameter less than three millimeters. The authors emphasize the importance of careful clinical follow-up.
