Transcatheter embolization with Onyx is feasible and safe in the peripheral arterial or venous vasculature for both bleeding and non-bleeding patients whatever the anatomic site.
Innovation has been the cornerstone of interventional radiology since the early years of the founders, with a multitude of new therapeutic approaches developed over the last 50 years. What is the future holding for us? This article presents an overview of the in-coming developments that are catching on at this moment, particularly focusing on three items: the new applications of existing techniques, particularly embolotherapy and interventional oncology; the cutting-edge devices; the imaging technologies at the forefront of the image-guidance. Besides this, clinical vision and patient relation remain crucial for the future of the discipline.
Background: Partial splenic embolization (PSE) has been used to improve thrombocytopenia related to hypersplenism. The optimal embolic agent is still debated. The purpose of this study was to evaluate the safety, hematologic response and outcomes of PSE with cyanoacrylate glue for oncological patients with hypersplenism-related thrombocytopenia requiring systemic chemotherapy (SC).Methods: Retrospective single-center observational report of cancer patients with thrombocytopenia related to hypersplenism and requiring SC who underwent PSE with N-butyl cyanoacrylate-methacryloxy sulfolane (NBCA-MS) Glubran ® 2 glue between February 2015 and September 2017. All patients were treated under local anesthesia with a Glubran ® 2/Lipiodol ® mixture of 1:5 ratio. They all received empiric antibiotic coverage. Splenic volume and parenchyma infarction rate were evaluated by CT scan within 1 month of PSE. Primary and secondary endpoints of the current study included a platelet count increase >150×10 9 /L and the initiation of SC, respectively. Periprocedural laboratory values and adverse events were recorded.Results: PSE was performed in eight patients (6 males, 2 females; median age, 59 years; range, 33-75 years) for a technical success of 100%. For procedures with adequate follow-up, primary and secondary endpoints were achieved in 100% (7 of 7 patients) and 100% (7 of 7 patients) of patients, respectively. One patient died before follow-up, unrelated to the procedure. Mean splenic infarction post-PSE was 55% (range, 21-70%) on CT scan. For 7 patients with laboratory follow-up, the mean platelet count significantly increased from 74×10 9 /L [range, (62-83) ×10 9 /L] immediately before PSE to a peak level of 272×10 9 /L [range, (161-417) ×10 9 /L] 10 days after PSE (P<0.05). All patients could receive SC after PSE. No non-target glue embolization occurred. All patients experienced a transient and moderate postembolization syndrome. No severe postembolization syndrome occurred. No major complication was reported. The mean overall survival was 7.9 months (range, 0.6-10.4 months) among the 8 patients after PSE. Conclusions: PSE with cyanoacrylate glue is safe and effective in the management of thrombocytopenia related to hypersplenism in cancer patients. It allows sufficient platelet count improvement for administration of SC.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
