Abstract

To investigate factors predictive of thromboembolic occlusions and evaluate the efficacy of percutaneous aspiration thrombectomy (PAT) for infrainguinal thromboembolic occlusions in patients undergoing endovascular recanalization (EVR). In this single-center retrospective study, 23 patients who underwent PAT for thromboembolism during EVR and 237 patients who underwent successful EVR without thromboembolic occlusions (control group) were enrolled. Immediate posttreatment and follow-up outcomes between groups were compared. Multivariate analysis was performed to identify factors predictive of thromboembolic occlusions. Technical success of PAT was defined as achievement of < 30% residual stenosis and restoration of modified thrombolysis in myocardial infarction grade 3 flow. The technical success rate was 95.7% in the PAT group. After intervention, ankle brachial index (ABI), restoration of blood flow, and improvement in dorsal/plantar arterial pulse score showed no significant differences between the PAT and control groups. During follow-up, no significant differences were observed between groups in improvement of sustained ABI and maximum walking distance, ulcer healing, restenosis/occlusion and limb salvage rates, and pain re...Continue Reading

Blood Clotting Disorders

Thrombophilia includes conditions with increased tendency for excessive blood clotting. Blood clotting occurs when the body has insufficient amounts of specialized proteins that make blood clot and stop bleeding. Here is the latest research on blood clotting disorders.
