Transcatheter electrosurgical aortic septostomy optimizes distal landing zone in chronic dissection.

ABSTRACT:

Objective

Efficacy of thoracic endovascular aortic repair (TEVAR) for chronic type B aortic dissection (CTBAD) is dependent on eliminating retrograde false lumen perfusion and remodeling the aorta. We describe the efficacy of a novel transcatheter electrosurgical technique to fenestrate the dissection flap and create a distal seal zone for TEVAR in CTBAD.

Methods

A retrospective review of the Emory Aortic Database from 2016 to 2023 identified 33 patients who underwent TEVAR with intentional endovascular rupture of the dissection flap (Knickerbocker; KNICK) for CTBAD. In 11 patients, we performed transcatheter electrosurgical aortic septostomy (TECSAS) before KNICK. The technical aspects of TECSAS + KNICK are described and results compared with TEVAR + KNICK alone.
