Key result
An asymptomatic left common carotid artery to left innominate vein arteriovenous fistula following laser-assisted transvenous lead extraction was successfully treated with an endovascular covered stent.
Case Report (n=1)
Endovascular covered stents can successfully treat arteriovenous fistulas complicating transvenous laser lead extraction.
Endovascular stenting may be feasible for rare asymptomatic post-extraction fistulas; leaves open incidence, risks, and optimal management.
Transvenous lead extraction (TLE) is used for lead infection, lead debulking, venous recanalization and device upgrades. Lead extraction is performed using specialized tools including locking stylets, mechanical or rotating sheaths, femoral snares or laser sheaths. The most feared complications associated with lead extraction are bleeding, vascular tear, cardiac avulsion and tamponade. Despite technological progress, the incidence of major procedural complications including death remains slightly above 1%. This case depicts an asymptomatic left common carotid artery (LCCA) to left innominate vein arteriovenous fistula (AVF) after laser-assisted TLE successfully treated with an endovascular covered stent.
