Enrollment was therefore stopped. No serious safety concerns were identified. Mechanical Thrombectomy Strategies Mechanical thrombectomy devices can be divided into three groups by mode of use. Distal clot-retrieval devices were developed and implemented first, followed by proximal aspiration devices, and then endovascular by-pass devices. Distal Clot Retrieval The first mechanical thrombectomy devices were advanced through the clot and delivered to its distal part via a microcatheter; the clot was then retrieved by pulling on the device.

The first stent used in this context was the Enterprise (Cordis, Miami Lakes, FL). , Plymouth, MN) is a self-expanding stent initially designed for stent-assisted coiling in remodeling of brain aneurysms (Fig. 7). It is currently offered in two versions: aneurysm bridging (AB) and flow restoration (FR). The Solitaire is unique in that it can be fully deployed and then completely retrieved if not detached [35, 87] once recanalization is established. Although detachment of the device is not within the primary scope for the treatment of ischemic stroke, it is a viable option if thrombectomy fails and thrombus compression by the deployed stent restores flow in the target vessel [72].

The left occipital lead was then replaced during revision surgery (b) Occipital Nerve Stimulation 31 reported following ONS, including the following: lead migration, infection, wound erosion, device failure, muscle spasms, and pain [1, 19]. Most commonly, lead migration is associated with ONS [18, 19] (Fig. 4). Often lead migration may require surgical intervention. Schwedt et al. demonstrated lead migration rates of 33 % after 6 months, 60 % after 2 years, and 100 % after 3 years [15]. In the authors’ experience, lead migration occurred in 7 % of patients.
