Bu ila\u00e7, i\u015flem sonras\u0131nda yeniden daralmaya yol a\u00e7abilen h\u00fccre \u00e7o\u011falmas\u0131n\u0131 azaltmay\u0131 ama\u00e7lar. Balon daha sonra s\u00f6nd\u00fcr\u00fclerek \u00e7\u0131kar\u0131l\u0131r; tedavi edilen b\u00f6lgeye yeni bir metal kafes yerle\u015ftirilmez.
\nBu \u00f6zellik, y\u00f6ntemi cazip k\u0131lar. Ancak stentin \u00f6nemli bir g\u00f6revi daha vard\u0131r: Damar\u0131 i\u00e7eriden destekleyerek a\u00e7\u0131k tutmak. \u0130la\u00e7 kapl\u0131 balon bu mekanik deste\u011fi sa\u011flamaz. Bu nedenle balonla geni\u015fletilen damar\u0131n yeterince a\u00e7\u0131k kalmas\u0131 ve kan ak\u0131m\u0131n\u0131n iyi olmas\u0131 gerekir.
\nStentin i\u00e7inde yeniden daralma varsa: Kan\u0131tlar\u0131n en g\u00fc\u00e7l\u00fc oldu\u011fu alan
\nStent tak\u0131lan bir b\u00f6lgede zaman i\u00e7inde yeniden daralma geli\u015febilir. B\u00f6yle bir durumda ila\u00e7 kapl\u0131 balon kullan\u0131lmas\u0131, mevcut stentin i\u00e7ine yeni bir metal katman eklemeden tedavi olana\u011f\u0131 sunar. Payla\u015f\u0131lan bilimsel veriler, stent i\u00e7i yeniden daralmada ila\u00e7 kapl\u0131 balonlar\u0131n ila\u00e7s\u0131z balonlara g\u00f6re daha etkili oldu\u011funu g\u00f6steriyor. Bununla birlikte, ila\u00e7 kapl\u0131 balon ile yeniden stent tak\u0131lmas\u0131 aras\u0131ndaki se\u00e7im her hastada ayn\u0131 de\u011fildir.
\n\u00d6zellikle ila\u00e7 sal\u0131n\u0131ml\u0131 stentin i\u00e7inde geli\u015fen yeniden daralmalarda, yeni bir ila\u00e7 sal\u0131n\u0131ml\u0131 stent uygulanmas\u0131, ayn\u0131 b\u00f6lgeye tekrar m\u00fcdahale gereksinimini azaltmak bak\u0131m\u0131ndan daha etkili olabilir. Buna kar\u015f\u0131l\u0131k, \u00fcst \u00fcste metal katmanlar\u0131ndan ka\u00e7\u0131nmak istenen hastalarda ila\u00e7 kapl\u0131 balon \u00f6nemli bir se\u00e7enektir.
\nBurada as\u0131l soru, \u201cHangi cihaz\u0131 kullanal\u0131m?\u201d sorusundan \u00f6nce gelir: Stent neden yeniden darald\u0131? Stentin yeterince a\u00e7\u0131lmam\u0131\u015f olmas\u0131 veya yap\u0131sal bir sorun bulunmas\u0131, yaln\u0131zca ila\u00e7 verilerek \u00e7\u00f6z\u00fclemez. Gerekti\u011finde damar i\u00e7i ultrason veya optik g\u00f6r\u00fcnt\u00fcleme ile nedenin belirlenmesi, do\u011fru tedavinin se\u00e7ilmesini sa\u011flar.
\n\u0130nce damarlarda: Uygun hastalarda g\u00fc\u00e7l\u00fc bir alternatif
\n\u0130nce kalp damarlar\u0131nda, k\u00fc\u00e7\u00fck miktarda yeniden daralma bile kan\u0131n ge\u00e7ti\u011fi alan\u0131 \u00f6nemli \u00f6l\u00e7\u00fcde azaltabilir. Bu nedenle damara yeni bir metal katman yerle\u015ftirmeden tedavi uygulanabilmesi \u00f6zellikle de\u011ferlidir.
