Abstract
Complications after implantation of articulated Palmaz-Schatz stents in coronary arteries of 3 patients are reported. In 1 patient, embolization of the stent occurred during the acute phase, and in the other 2 patients, we observed restenosis after 4 and 5 months, respectively. Late restenosis was located in the midportion and the distal end of the stent in 1 patient. In the other patient a severe subtotal occlusion was found 1 cm proximal to the stent. These findings suggest that adaptation of the stent delivery system is needed to prevent loss of the stent and scraping of the vessel wall.
