Background And Purpose: Aspiration is a successful technique used in thrombectomy for acute stroke. It is contingent upon the appropriate position of the aspiration catheter, so that it is in contact with the thrombus. However, navigating the craniocervical vasculature is challenging is some patients. The wedge microcatheter (MicroVention®) is designed to reduce the gap between the microcatheter and the SofiaPlus 6F catheter for ease of advancement. The purpose of this study is to describe our initial experience with the wedge microcatheter.
Materials And Methods: A retrospective review of 38 consecutive patients in whom the wedge microcatheter was used during thrombectomy was performed to determine whether the wedge microcatheter was successful in delivering the Sofia catheter to the desired location.
Results: We have found this device to be successful in delivering the aspiration catheter to the correct position in 97% ( = 37) of cases. It was used predominantly to pass the origin of branching vessels and also to navigate the tortuous cavernous and petrous segments of the ICA.
Conclusion: The wedge microcatheter is a successful tool in delivering the aspiration catheter to the desired vessel for revascularisation.

Sublober resection of small peripheral lung lesions using video-assisted thoracoscopic surgery may require marking and confirmation using 3D imaging in the interventional radiology suite or in the hybrid operating room (HOR) before surgery is started. We report a novel approach for intraoperative transbronchial metallic coil marking followed by thoracoscopic wedge resection in a conventional operating room under mobile 3D C-arm guidance. Under general anesthesia, an ultrathin video-bronchoscope was inserted into an objective bronchus guided with virtual bronchoscopic navigation, and a coil-feeding microcatheter was introduced through the bronchoscope's channel.

Parent artery occlusion is a definitive treatment method for preventing rebleeding of dissecting aneurysms. We herein report a case of a ruptured distal posterior inferior cerebellar artery (PICA) dissecting aneurysm treated with internal trapping using n-butyl-2-cyanoacrylate (NBCA). A 65-year-old man visited our hospital with a complaint of headache and neck pain that began 1 week before his arrival.

In recent years, A Direct Aspiration First Pass Technique (ADAPT) has emerged as an effective and safe method of thrombectomy. Large trials have shown noninferiority of ADAPT compared to primary stent retriever approach, while new studies emphasize on its shorter procedural time with potentially fewer complications and costs..

Balloon and microcatheter uncrossable chronic total occlusions can be challenging to treat. We present a novel technique for treating such lesions through contrast injection via a guide catheter extension wedged against the proximal cap. We named this technique "guide-extension Carlino.

Objective: Currently, there are no established approaches for removal of devices, such as stents, which sometimes become difficult to recover during endovascular treatment. We report a new method to successfully remove a stent that has become snagged during thrombus removal.
Case Presentation: An 82-year-old female who had undergone a mitral valve annuloplasty developed sudden aphasia, right hemiplegia, and right unilateral spatial neglect on postoperative day 10.
