Background RESILIENT is a prospective, multicenter, randomized phase III trial to test the safety, efficacy, and cost-effectiveness of mechanical thrombectomy as compared to medical treatment alone in patients treated under the less than ideal conditions typically found in the public healthcare system of a developing country. Methods Subjects must fulfill the following main inclusion criteria: symptom onset ≤8 h, age ≥18 years, baseline NIHSS ≥8, evidence of intracranial ICA or proximal MCA (M1 segment) occlusion, ASPECTS ≥6 on CT or >5 on DWI-MRI and be either ineligible for or unresponsive to intravenous alteplase. The primary end-point is the distribution of disability levels (on the modified Rankin Scale, mRS) at 90 days under the intention-to-treat principle. Randomization Randomization is performed under a minimization process using age, baseline NIHSS, intravenous alteplase use, occlusion site and center. Design The trial is designed with an expectation of a 10% difference in the proportion of favorable outcome (mRS 0–2 at 90 days) common odds ratio of 1.615. Primary outcome Projected sample size is 690 subjects with pre-planned interim analyses at 174, 346, and 518 subjects. Secondary outcomes Secondary end-points include: 90-day functional independence (mRS ≤2), mRS shift stratified for treatment with IV rt-PA at 90 days, infarct volume on 24 h CT or MRI, early dramatic response (NIHSS 0–2 or improvement ≥8 points) at 24 h, vessel recanalization evaluated by CTA or MRA at 24 h, and the post-procedure rate of successful reperfusion (defined as a modified Treatment in Cerebral Infarction 2b or greater). Safety variables are mortality at 90 days, symptomatic intracranial hemorrhage at 24 h and procedure-related complications.
Splenic artery pseudoaneurysm is an extremely rare entity, although it is the most frequent location of visceral pseudoaneurysms. Trauma or previous pancreatitis (where the proteolytic pancreatic enzymes lead to the formation of pseudoaneurysm, as a result of enzymatic injury to the splenic artery wall) (Amico and Alves in Pancreatology 14: 144-145, 2014) is the most frequent causes. A high degree of suspicion is required for the accurate diagnosis. The authors present a case of splenic artery pseudoaneurysm in a middle-aged man who came to the emergency department with several days of abdominal pain.
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.
