With increasing incidence ofstent deployment, theproblemoJISR "the
Achilles heel ofsterding" is becoming increasingly prevalent and remains
the major limitation of coronary catheter based interventions. Aim of the
work: To evaluate the mid-term clinical outcome after PCIfor treatment of
differentpatterns oflSR and to make angiographicfollow-upfor pdtients
with clinical restenosis. Thirty patients with ISR underwent successful
PCIfromSeptember 2002 inNasr City InsuranceHospital and werefollowed-
up clinically and by exercise stress testingfor sixmontlrs after the
procedure: Angiographic follow-up was done for patients with recurrent
symptoms (one patient) or with positive stress test results at follow-up
(onepatient). 80% ofourpatients underwent successfulPCI using conven
tional balloon and in the remaining 20% cutting balloon was used. We
found no difference between bothfor treatment ofISR at six monthsfol
low-up (P=0.66). In the current study, only two patients (6.7%) had clini
cal and angiographic ISR. The remaining (93.3%) had afavorable clinical
outcome. In conclusion: Repeat balloon angioplasty for the treatment of
ISR is an easy and safeprocedure with high procedural success, but it s
worthy to say that best management ofISR is not completely established.
So, prevention ofISR at the outset should be tire ultimate aimand in this
issue drug-eluting stents (DES) may be an outstanding option. |
