In Situ Fenestrated Thoracic Endovascular Repair Using the Upstream Peripheral Go BackTM Re-Entry Catheter

Abstract

Purpose: The aim is to present a case of in situ fenestrated thoracic endovascular repair, using a re-entry peripheral catheter, needing urgent repair due to recurrent episodes of hemoptysis because of an aorto-bronchial fistula after previous thoracic endovascular aortic repair (TEVAR). Technique: A 74-year-old male with a previous TEVAR presented with hemoptysis, fever, and cachexia. An aorto-bronchial fistula and type Ia endoleak were depicted on computed tomography angiography (CTA). Due to the patient’s frail general condition, a proximal TEVAR extension was planned, prior to thoracotomy for debridement, and long-term antibiotics. An in situ fenestrated TEVAR was performed to provide proximal sealing and revascularize the left common carotid and subclavian arteries. For fenestration creation, an Upstream Peripheral Go Back catheter (Bentley, Hechingen, Germany) was used. The Go Back catheter has been approved as a re-entry tool for complex peripheral arterial revascularization. In this case, both fenestrations were successfully created. Proximal seal and target vessel patency were confirmed on CTA. Thoracotomy confirmed aortic exclusion. A wedge lobectomy was performed in combination with pediculated omentectomy to exclude the exposed endograft. Conclusion: In urgent cases, where custom-made thoracic devices are unavailable, in situ fenestrations with the Go Back catheter are an alternative to laser fenestrations. Clinical Impact Fenestrations are often required in acute TEVAR to achieve a proximal seal in the arch. In situ fenestrations with the Go Back catheter are an alternative to laser fenestrations and PMEGs in this setting.
