Technique for Recanalization of Sheath Introducer Occlusion due to Captured Thrombus during Mechanical Thrombectomy for Acute Ischemic Stroke: A Technical Note.

Objective: Mechanical thrombectomy (MT) is the gold standard treatment for acute ischemic stroke. During these interventions, a thrombus frequently obstructs a guiding catheter. The obstructed guiding catheter should be withdrawn before distal embolism occurs; however, albeit infrequently, the thrombus occludes even a sheath introducer (SI).

Efficacy of transcutaneous cardiac pacing for transient asystole caused by trigeminocardiac reflex: illustrative case.

Background: Trigeminocardiac reflex (TCR) is a brainstem reflex caused by stimulation of the trigeminal nerve, which results in bradycardia, hypotension, and asystole. TCR can occur during any neurosurgical procedure. Initially, it is managed via the immediate removal of the stimulus from the trigeminal nerve.

Crystal structure of -(1-indol-2-yl-methyl-idene)-4-meth-oxy-aniline.

The mol-ecule of the title compound, CHNO, contains an essentially planar indole ring system and a phenyl ring. In the crystal, the mol-ecules are linked by a weak inter-molecular C-H⋯O hydrogen bond and C-H⋯π inter-actions, forming a one-dimensional column structure along the axis direction. These columns are linked by other C-H⋯π inter-actions, forming a two-dimensional network structure.

An anomalous hyperplastic anterior choroidal artery associated with an unruptured internal carotid-posterior communicating artery aneurysm.

The anterior choroidal artery (AChA) injuries can result in severe neurologic deficits, so requiring careful observation to avoid inadvertent damage during neuroendovascular procedures. In this case report, we present the unusual case of an anomalous hyperplastic AChA associated with a fetal-type posterior communicating artery (PCoA), and an unruptured internal carotid artery (ICA) -PCoA aneurysm. A 54-year-old woman presented with persistent headache.

Combined Experimental and Theoretical Studies on Planar Chirality of Partially Overlapped -Symmetric [3.3](3,9)Dicarbazolophanes.

Partially overlapped dicarbazolophanes exhibit a planar chirality. In this study, -symmetrical [3.3](3,9)dicarbazolophane derivatives (-) have been optically resolved by preparative chiral high-performance liquid chromatography for the first time.
