Multicentre Study of Effectiveness of MANTA VCD After Percutaneous Femoral Access for Endovascular Aortic Repair and Thoracic Endovascular Aortic Repair

Purpose: To evaluate the safety and effectiveness of MANTA close device employment after percutaneous femoral access for endovascular aortic repair (EVAR) and thoracic endovascular aortic repair (TEVAR)

Materials and Methods: This was a retrospective multicentre study. All 212 patients were treated between April 2017 and October 2021 for abdominal aortic aneurysms and thoracic aortic pathology. There were 33 women and 179 men; the mean age was 68 years ± 6 years. In all patients, femoral access was used with 9- to 14-Fr sheaths for graft implantation. The primary effectiveness endpoints was technical success, including freedom of acute bleeding and thromboembolic events. After intervention, groin elastic bandage were used in all cases for 24 hours.

Results: Technical success of MANTA closure device implantation was 100%. In two cases, groin hematoma was detected after 24 hours; no revisions were performed. Computed tomography angiography (CTA) after intervention confirmed no major vascular access site complications requiring surgical treatment. No thrombotic or embolic complication were detected in the first 30 days. After 6- to 12-month CTA, no local aneurysms were detected.

Conclusions: The MANTA closure device is safe and effective for vascular access closure after percutaneous femoral access for aortic graft implantations.
