PURPOSE: To determine the safety and outcomes of performing endovascular interventions across pacemaker (PM) lead-related central @entity850 /occlusion. MATERIALS AND METHODS: Clinical and imaging records from April 2002 to August 2010 were reviewed for @entity1 presenting with clinically significant central @entity1211 or central @entity432 with indwelling PM leads and were evaluated to determine if any @entity409 or complications occurred following intervention. Thirteen @entity1 were identified who underwent 14 interventions. Outcomes were assessed based on recurrent clinical symptoms and repeat venograms, and patency was determined with Kaplan-Meier analysis. RESULTS: All procedures were technically successful (100%) with no procedural complications. All @entity1 underwent balloon angioplasty; two @entity1 also underwent stent placement for persistent flow-limiting @entity850 within the superior vena cava. No incidence of PM or @entity409 , @entity281 , or need for PM intervention was identified in any @entity1 at the time of the index procedure and at 30 or 90 days. In the two @entity1 who received stents across PM leads, no manifestations of PM or @entity409 or @entity281 , or need for intervention, were identified at 1 year after stent placement in one @entity1 and at 3 years in the other @entity1 . For eight @entity1 , sufficient follow-up studies were available, with 30-, 60-, and 120-day primary patency rates of 87.5%, 75%, and 50%, respectively. CONCLUSIONS: Endovascular interventions across PM leads resulted in no adverse clinical cardiac or PM sequelae, but with limited primary patency compared with historical outcomes for central venous interventions in the absence of PM leads.
