Abstract Existing methods for biopsy of intraparenchymal brain lesions, including stereotactic biopsy and open block biopsy, have advantages and disadvantages. We propose a novel biopsy method, called “boring biopsy,” which aims to overcome the d

We present the case of a 74-year-old woman complaining of blurred vision in the left eye who was found to have a unilateral, continuous lesion of the optic nerve and nerve sheath accompanied by an intracranial mass next to the cavernous sinus and men

Background Mechanical endovascular embolectomy using stent retrievers has gained popularity for treatment of large vessel occlusion in acute ischemic stroke. Use of open embolectomy as a direct surgical treatment has been limited, likely owing to the

Background There is still a controversy for low-flow extracranial–intracranial or high-flow extracranial–intracranial bypass with proximal occlusion in the treatment of unclippable giant internal carotid artery aneurysms. Case Description A 61-ye

We demonstrate an optical phase-locked system for a 640 Gbaud optical Nyquist pulse transmission with a mode-locked laser based local oscillator. Carrier-phase synchronization with a phase noise of as low as 0.65 degrees was achieved after a 150 km t

We report a polarization-multiplexed 320 Gbaud, 64 QAM coherent Nyquist pulse transmission with a frequency-stabilized mode-locked laser and a modified digital back-propagation method for pulse transmission. Using a combination consisting of a mode-l

We report a polarization-multiplexed 320 Gbaud, 64 QAM coherent optical Nyquist pulse transmission with a frequency-stabilized mode-locked laser. Single-channel 3.84 Tbit/s data were successfully transmitted over 150 km with a spectral efficiency of

We achieved a record capacity of 7.68 Tbit/s in a single-channel OTDM transmission with a 9.7 bit/s/Hz spectral efficiency, where a polarization-multiplexed 640 Gbaud, 64 QAM coherent Nyquist pulse has been transmitted over 150 km. In this scheme, a

Background: The authors present a modified interhemispheric approach for the distal ACA aneurysm to resolve several problems including the narrow surgical corridor, the difficulty of proximal control, and the aneurysmal projection toward the surgeon.

Objective The aim of this article is to present the usefulness of a double-bypass method in the surgical treatment of complex internal carotid artery (ICA) aneurysms. For patients with clippable but complex aneurysms of the ICA having poor collateral
