Perkütan Koroner Girişim Sırasında Gelişen Stent Kaybının Sıklığı, Demografik Özelliklerinin ve Tedavilerinin Değerlendirilmesi: Tek Merkez Deneyimi

Objective: The aim of this study was to evaluate the demographic characteristics, incidence of stent loss, treatment methods and 30-day outcomes of the patients with stent loss during percutaneous coronary intervention (PCI). Materials and Methods: Fifteen patients who lost a stent during PCI between December 2014 and February 2020 were included in the study. Outcomes were classified as myocardial infarction, requirement of bypass revascularization and mortality within 30 days. Results: In our study, the incidence of stent loss during PCI was 0.15%. Of these patients, 12 (80%) were male. The mean age of the patients was 59.87 ± 8.67 years. In 3 patients, the stent was deployed at the same location, while in 4 patients, stent crush technique is used. The following retrieval methods were used: inflating the small balloon (%33.33) and snare (%20). One patient underwent coronary bypass surgery. One patient died in the hospital. Death, myocardial infarction andrequirement of bypass were not observed in the one-month follow-up in the remaining patients. Six patients had type C and 7 patients had type B2 lesions. Eight of the lesions were in left circumflex artery. Conclusion: Coronary stent loss occurs more frequently in the left circumflex artery, and in type B2/C lesions in particular. Interventional cardiologists should know that different treatment methods are available for stent loss in lesions according to the location of the stent, and should be able to successfully treat stent loss in the light of the current data.
