Thoracic Aortic Endograft Explant: A Single-Center Experience

Abstract

Although rare, familiarity with TEVAR explant is imperative as it is increasingly performed for broader indications. Our limited data suggest that explant can be performed successfully albeit with morbidity.

Reinterventions during midterm follow-up after endovascular treatment of thoracic aortic disease

“…[25][26][27] Reported conversion rates after TEVAR vary between 3.8% and 4.6% with endoleaks, disease progression, retrograde aortic dissection, and aortoesophageal fistulas being the most common cause, which is in line with our series (conversion rate, 4.1%). 12,28,29 There was a lower reintervention rate for emergency cases in this series. This is possibly caused by the higher mortality rate of patients requiring emergency TE-VAR, leaving fewer patients at risk for reinterventions.…”

Biomechanical Changes After Thoracic Endovascular Aortic Repair in Type B Dissection

“…In a cohort of 500 patients with thoracic aortic diseases, 4 patients required stent-graft explantation due to device failure (the deployment system could not be disengaged), aortoesophageal fistula, retrograde AD, and severe type I endoleak (aneurysmal patient). 130 Other reported indications for stent-graft explantation include deployment-related problems, stent-graft infection, migration, collapse, kinking, aortic rupture, and fracture. 39,124,131,132 In the presence of highly unstable hemodynamic conditions, TEVAR has also been proposed as a bridge to open surgery.…”

Homograft Treatment for Infected Frozen Elephant Trunk Prosthesis

“…Graft infection is a disastrous complication after aortic repair with reported incidence of 0.2-5% and morbidity rates exceeding 35% [Cappabianca 2017;Heyes 2009;Kirkwood 2010;Smeds 2016;Touma 2014. ] The presence of tracheoesophageal fistula adds to this treatment challenge.…”
