Abstract

Objective. The aim of the study was to assess safety and reliability of using the MANTA closure device in endovascular treatment of patients with aortic aneurysms.

Patients and methods. The obtained results were retrospectively analysed based on the experience of treating 19 patients (from July 01, 2021 to November 31, 2021) for abdominal aortic aneurysms (n=14) and thoracic aortic pathology (n=5). All operations were performed at the Vascular and Endovascular Surgery Clinic, St. Katharine’s Hospital, Frechen, Germany. In all cases, sheaths 9–14F were used for graft implantation. The primary endpoint of efficacy was technical success, with neither acute bleeding nor thromboembolic complications. In our study we used the MANTA closure device (Teleflex, Wayne, Pennsylvania), a novel device for closing percutaneous access to the femoral artery following the use of 10–20F (12–25F OD) devices or sheaths in endovascular catheterization procedures.

Results. Of the total number of patients, three had a dissection of the thoracic aorta, two penetrating aortic ulcer, in 14 cases aneurysm of the abdominal aorta. The mean age of the patients was 67±2.2 years. There were 16 males and 3 females. Of the 19 patients, bilateral access was used in 18 (37 inguinal approaches), in one case a monoiliac graft was implanted. The technical success of implantation of the MANTA closure device was 100%, with no conversion to open access to the femoral vessels. The findings of CT angiography confirmed neither complications in the area of ​​the vascular access, nor stenosis of the access area requiring surgical treatment. Fourteen of the 19 patients underwent ultrasound duplex scanning of vessels in the access zone prior to discharge from the clinic, demonstrating no significant stenosis in the area of arterial closing.

Conclusion. The use of the MANTA CD closure device is safe and accompanied by good immediate results, however, further experience is needed with this device.
