AbstractObjective The aim of this study was to evaluate the incidence of venous stenosis and occlusion (VSO) in patients referred for transvenous lead extraction (TLE) with regard to the indications for this treatment and to analyse the influence of VSO on efficacy, complications and technical challenges of TLE procedures. Methods The material consists of 133 consecutive TLE procedure records. The contrast venography examination of the ipsilateral access vein was performed prior to the operation. The whole study population was divided into two subgroups, based on the presence (subgroup I) or absence (subgroup II) of VSO. Results Phlebography was performed in 133 patients with age ranging from 25.7 to 86.1 years, 44 female (33.1%). The VSO was confirmed in 48 (36.1%) patients - subgroup I. Most of the patients were referred to TLE due to non-infectious reasons (100 pts-75.2%). The absence of VSO was observed substantially more frequently in patients with diabetes (P = 0.02). Procedural success rate reached 93.3% in subgroup I and 98.8% in subgroup II (P = 0.1). There was no significant difference in the use of advanced tools and alternative access sites. Conclusion The presence of VSO can be expected in one third of patients referred for lead extraction. There is no association between indication for TLE (infected or noninfected lead extraction) and the incidence of VSO. Diabetes proved to have a protective effect on venous patency in the previously mentioned group. VSO does not influence the effectiveness, safety, and the use of additional tools during TLE procedures.
