Purpose:
Pseudoaneurysm (PSA) developing after catheter examinations is one of the most frequent vascular complications and a nonsurgical technique with utmost low risk of complications is warranted. Our aim was to investigate the technical feasibility, success, and safety of transaneurysmal occlusion of complicated post-interventional common femoral artery (CFA) PSA using the Angio-Seal Closure Device (ASCD) and a technique that we describe as the transaneurysmal (TA) maneuver.
Material And Methods:
We used the Angio-Seal (Terumo, Tokyo, Japan) Closure System to manage complicated PSAs in patients who would otherwise have needed surgery after failure of all conservative therapies. The TA maneuver was performed in 14 consecutive patients from July 2021 to July 2022. After ultrasound-guided puncture of the PSA close to its neck, the CFA was entered radiographically with micro-guidewires, and the neck of the PSA was closed with the ASCD after changing the sheaths and wires. All patient had to wear a pressure dressing until the next day, when successful closure was verified by sonography.
Results:
All procedures were performed with technical success and without any complications. No patient had to undergo surgery. All sonographies on the next day confirmed complete absence of perfusion within the PSA and normal flow conditions of the CFA and vessels below.
Conclusion:
The TA maneuver a promising minimally invasive procedure for closing complicated PSA of the CFA after catheter examination.
