Avaliação da segurança dos procedimentos de extração de cabos-eletrodos

Abstract

After years of implantation of leads and implantable electronic devices, complications arise in the most varied ways. Percutaneous lead extraction presents itself as an appropriate treatment. The objective of this study is to evaluate the biosafety of percutaneous lead extraction procedures up to thirty days postoperatively, in patients with mandatory indication and necessary indication. Clinical retrospective and intervention study with patients who underwent lead extraction at the University Hospital Pedro Ernesto (UERJ), from October 1994 to August 2020. Evaluated 621 medical records of patients, with 1 552 leads extraction, with an average of 2,5 leads/patients. Patients were stratified into two groups of infected patients (mandatory) n= 330 and non-infected patients (necessary) n= 291. The lead extraction technique and its results followed the guidance of HRS. Surgical success was achieved in 91,6% of patients, clinical success in 6,6% and failure in 1,8%. Fatal complications occurred and were more frequent in the group of mandatory indication. Endocarditis was the most common cause. In conclusion there was no significant difference in death and complication between groups. Lead extraction is a safe procedure and should be performed reducing the chance of intravascular occlusion and the high risk of long-term prosthesis infection.
