Outcome of Secondary Interval Rheolytic Thrombectomy after Localized Intra-Arterial Catheter-Directed Thrombolysis through Power-Pulse Spray Technique in Cases of Partially Successful or Failed Primary Rheolytic Thrombectomy

Résumé fourni par la source

Objectives The aim of this study was to evaluate the safety and effectiveness of secondary interval AngioJet rheolytic thrombectomy after localized intra-arterial catheter-directed thrombolysis (CDT) through power-pulse spray (PPS) technique in partially successful or failed primary AngioJet rheolytic thrombectomy cases of acute and subacute peripheral artery thrombosis. Materials and Methods This retrospective study included 12 acute (< 2 weeks) and subacute (2–4 weeks) peripheral arterial thrombosis patients who underwent primary thrombectomy alone without CDT and patients who received secondary thrombectomy after CDT through PPS at our institute between May 2022 and December 2022. Technical success, procedure-related complications (local and systemic), amputations, and 1-year patency were evaluated. Results The angiographic success after primary thrombectomy was evaluated in 12 patients (9 acute and 3 subacute), and the results were categorized into three groups. Of 12 patients, complete success, partial success, and failure were noted in three (25%), five (41.7%), and four (33.3%) patients, respectively, after primary thrombectomy alone. Complete luminal patency was restored in all nine cases of partial success and failure in postprimary thrombectomy through adjunctive PPS thrombolysis
