Introduction: Technical improvement to enhance M2 occlusion thrombectomy is desirable. Tron FX® is the only stent-retriever that can be deployed through 0.0165-inch microcatheters. Here we report outcomes of blind exchange with mini-pinning (BEMP) technique using Tron stent-retrievers. Methods: Consecutive stroke patients with M2 occlusion treated with 2 x15 mm or 4 x 20 mm Tron stent-retrievers using the BEMP technique were included. The technique involves the deployment of a Tron stent-retriever through a 0.0165-inch microcatheter followed by microcatheter removal and blind navigation of a 3/4MAX aspiration catheter over the bare Tron delivery wire until the aspiration catheter reaches the clot,. Tron stent-retriever was inserted into aspiration catheter like corkscrew, and subsequently pulled as a unit. A first pass effect (FPE), modified FPE (mFPE) and modified Rankin Scale (mRS) score at 90 days were assessed as outcomes. Results: Fifteen M2 vessels were treated in 13 patients (5 women, median 81 years of age, and median National Institutes of Health Stroke Scale score 18 [11–25]). BEMP technique was successful in all cases. Whether to use 3MAX or 4MAX was determined according to the target vessel size while proceeding with the procedure (3MAX, n=8; 4MAX, n=5). Final mTICI 2b–3 was achieved in 92% (12/13). FPE and mFPE rates were 50% and 64%, respectively. Six patients (46%) were achieved in mRS score 0–2 at 3 months. Conclusions: Tron stent-retriever was successfully and safely used in the BEMP technique for M2 occlusion

The Ideal

Success in laryngotracheal reconstruction has been limited, in part, by the lack of an ideal grafting material. Perichondrium is thin, pliable, and highly vascularized and has the ability to generate new cartilage providing rigid support. These qualities make vascularized perichondrium potentially the ideal grafting material for circumferential airway stenosis. A pedicled vascularized flap of auricular perichondrium was used in a rabbit model (n = 39) to reconstruct a near-circumferential tracheal defect without a tracheostomy. A stent was used to support the reconstructed airway for 6 weeks, after which time it was removed by direct laryngoscopy. Animals were observed for an additional 6 weeks prior to sacrifice. Qualitative and quantitative histologic analysis of neochondrogenesis is reported. Vascularized perichondrium and periosteum show promise as potential grafts for reconstruction of circumferential tracheal defects.

The Ideal

The technique of labeling of macromolecules with ferritin conjugated antibody has been successfully used for extracellular antigen by means of staining the specimen with conjugate prior to fixation and embedding. However, the ideal method to determine the location of intracellular antigen would be to do the antigen-antibody reaction in thin sections. This technique contains inherent problems such as the destruction of antigenic determinants during fixation or embedding and the non-specific attachment of conjugate to the embedding media. Certain embedding media such as polyampholytes (2) or cross-linked bovine serum albumin (3) have been introduced to overcome some of these problems.

The Ideal

The reconstruction of a three-dimensional image of a specimen from a set of electron micrographs reduces, under certain assumptions about the imaging process in the microscope, to the mathematical problem of reconstructing a density distribution from a set of its plane projections.In the absence of noise we can formulate a purely geometrical criterion, which, for a general object, fixes the resolution attainable from a given finite number of views in terms of the size of the object. For simplicity we take the ideal case of projections collected by a series of m equally spaced tilts about a single axis.
