Thoracic Endovascular Aortic Repair Using the C-TAG® Device with ACTIVE CONTROL System

Area of Science:

• Vascular Surgery
• Medical Device Technology
• Thoracic Aortic Disease

Background:

• Thoracic endovascular aortic repair (TEVAR) is a minimally invasive treatment for thoracic aortic pathologies.
• Accurate endograft deployment and apposition are crucial for successful TEVAR outcomes.
• The Gore® C-TAG® endograft with ACTIVE CONTROL System (ACS) is designed to enhance deployment precision.

Purpose of the Study:

• To evaluate the performance of the Gore® C-TAG® endograft with ACS in thoracic aortic repair.
• To assess the accuracy of endograft deployment and its apposition to the aortic wall.
• To report single-center experience with this specific endograft system.

Main Methods:

• Retrospective analysis of 28 patients undergoing TEVAR with Gore® C-TAG® with ACS (September 2017-September 2021).
• Collection of anatomic data including aortic arch characteristics and landing zones.
• Measurement of proximal and distal deployment accuracy (PDA, DDA) and aortic wall apposition via angiography and CT angiography.

Main Results:

• Mean PDA was 1.89 ± 3.5 mm and mean DDA was 0.6 ± 1.4 mm.
• Mean proximal wall apposition was 91 ± 17% and distal apposition was 98 ± 5.9%.
• Two patients required reintervention for type 1a endoleak during hospitalization; no further reinterventions were needed.

Conclusions:

• The Gore® C-TAG® endograft with ACS demonstrated promising results in thoracic aortic repair.
• Optimal accuracy in deployment and excellent aortic wall apposition were achieved.
• This system appears effective for TEVAR procedures requiring precise placement.
