Early Postmarket Results with EmboTrap II Stent Retriever for Mechanical Thrombectomy: A Multicenter Experience.

BACKGROUND AND PURPOSE: EmboTrap II is a novel stent retriever with a dual-layer design and distal mesh designed for acute ischemic stroke emergent large-vessel occlusions. We present the first postmarket prospective multicenter experience with the EmboTrap II stent retriever. MATERIALS AND METHODS: A prospective registry of patients treated with EmboTrap II at 7 centers following FDA approval was maintained with baseline patient characteristics, treatment details, and clinical/radiographic follow-up. RESULTS: Seventy patients were treated with EmboTrap II (mean age, 69.9 years; 48.6% women). Intravenous thrombolysis was given in 34.3%, and emergent large-vessel occlusions were located in the ICA (n = 18), M1 (n = 38), M2 or M3 (n = 13), and basilar artery (n = 1). The 5 × 33 mm device was used in 88% of cases. TICI ≥ 2b recanalization was achieved in 95.7% (82.3% in EmboTrap II-only cases), and first-pass efficacy was achieved in 35.7%. The NIHSS score improved from a preoperative average of 16.3 to 12.1 postprocedure and to 10.5 at discharge. An average of 2.5 [SD, 1.8] passes was recorded per treatment, including non-EmboTrap attempts. Definitive treatment was performed with an alternative device (aspiration or stent retriever) in 9 cases (12.9%). Some hemorrhagic conversion was noted in 22.9% of cases, of which 4.3% were symptomatic. There were no device-related complications. CONCLUSIONS: Initial postmarket results with the EmboTrap II stent retriever are favorable and comparable with those of other commercially available stent retrievers. Compared with EmboTrap II, the first-generation EmboTrap may have a higher first-pass efficacy; however, data are limited by retrospective case analysis, incomplete clinical follow-up, and small sample size, necessitating future trials.

Challenges facing human rabies control: the Lebanese experience.

Rabies is one of the most important zoonotic infections worldwide. The burden of the disease continues to be significant in countries in the Middle East where the most important vector is stray dogs. Control efforts are hindered by lack of awareness and incomplete post-exposure prophylaxis. The aim of this article is to re-assess the situation of rabies in Lebanon and compare it to other Middle Eastern countries. Eight cases of rabies and 5280 incidents of animal bites to humans were reported to the Lebanese Ministry of Public Health between 2001 and 2012. Dogs were the only vector of infection and were responsible for most reported animal bites to humans. An average of 3·2 doses of vaccine per bite was administered as post-exposure prophylaxis. The status of human and canine rabies control, the risks associated with children's behaviour and the hazards of secondary wild reservoirs are discussed. Our data illustrates the importance of prevention through vector control, public awareness and education, and timely administration of active and passive immunization, as well as the significance of regional cooperation and monitoring the circulation of viral variants in wild animals.
