Practical Applications Of Tack Implants For Infrainguinal Dissection Repair: A Single-Center Experience
JOURNAL OF ENDOVASCULAR THERAPY(2020)
Abstract
Purpose: To assess the practical application and acute outcomes of the Tack Endovascular System for infrainguinal dissection repair in a real-world setting. Materials and Methods: Fifty-one consecutive patients who underwent endovascular revascularization for symptomatic peripheral artery disease and experienced 63 dissections requiring treatment were included in the prospective, single-center, single-arm study between January and June 2019. Thirty-nine (76.5%) lesions were >= 10 cm in length, 33 (64.7%) were totally occluded, and 13 (25.5%) were severely calcified. Fifty-six (88.9%) dissections were classified as severe. Dissections were treated either by means of the 6-F above-the-knee (ATK) or the 4-F below-the-knee (BTK) Tack Endovascular System. Observational outcomes were conditions and scopes of application. Clinical outcomes were acute technical and procedural success as well as safety. Results: Lesions were revascularized with 2.3 +/- 0.8 attempts such as standard balloon angioplasty, drug-coated balloon angioplasty, atherectomy, and/or lithotripsy. The Endovascular System was applied in 60 (95.2%) of 63 dissections. All dissections of the femoral artery were treated with the ATK system, and all infrapopliteal dissections with the BTK system. Both systems were successfully applied in popliteal artery dissections. Dissection length predicted the number of Tack implants deployed. Technical success was achieved in 98.3% (59 of 60 dissections). No major adverse event or device-related complication occurred during the procedure. Conclusion: Acute results in effectiveness and safety of the Tack Endovascular System for infrainguinal dissection repair in a real-world setting are promising.
