Treatment of Type I Endoleak after Thoracic Endovascular Aortic Repair and Stent Extension via False Lumen Catheterization and Coil Embolization.

Thoracic endovascular aortic repair (TEVAR) is a minimally invasive alternative to conventional open surgical reconstruction for the treatment of thoracic aortic dissection. However, the possibility of a type I endoleak may contribute to false lumen enlargement and rupture. Here, we present a case of successful treatment of type I endoleak after TEVAR and endograft extension for a complicated descending thoracic aortic dissection that was embolized by coils via a false lumen channel through the distal entry tear. This endovascular technology might offer a new option to treat thoracic type I endoleak by embolizing the blood entry site of the endoleak through the distal entry site and false lumen.
