When resident physicians fail to demonstrate appropriate milestone competencies early in their neurologic surgery residency, a plan of remediation is necessary. ⋯ Finally, a discussion of the prior resident remediation studies across many disciplines is made.

The principles of endovascular treatment of bilateral cavernous sinus dural arteriovenous fistula (CS-dAVF) are not well established because of the complexity in the number of fistula tracts and their behavior, which seems to be more aggressive. We aimed to determine an efficient technique for endovascular treatment of bilateral CS-dAVF and the associated factors to achieve good clinical and angiographic outcomes. ⋯ Dangerous venous drainage tends to increase in bilateral CS-dAVF. Retrograde ipsilateral inferior petrosal sinus catheterization using coil embolization and sequencing the embolization are the major concerns for treatment.

Few studies have investigated the financial influence of surgical site local morselized bone autograft (LMBA) on the overall cost of spinal arthrodesis procedures. The purpose of this study is to evaluate the potential savings from introducing LMBA in spinal fusion procedures compared with no LMBA use. ⋯ LMBA is a cost-saving bone graft extender option in MI-TLIF procedures while achieving high fusion rates. The savings are mainly achieved by reducing the amount of allograft needed and subsequent reduction in the total bone graft costs. Further research needs to be performed regarding long-term economic benefit.

Here we report the application of optical frequency domain imaging (OFDI), a new optical coherence tomography device, for intravascular visualization in the treatment of a recanalized unruptured internal carotid artery aneurysm that was treated initially by stent-assisted coil embolization. ⋯ OFDI/OCT appears to be a useful diagnostic tool for evaluating stent-strut apposition over the vessel wall and the grade of neointimal endothelialization across the neck of the aneurysm in aneurysmal recanalization.

Continuous Interrupted Double Throw Suturing Method: A novel suturing technique for Extracranial-Intracranial Bypass.
Despite failure of the EC/IC Bypass Study Group to demonstrate effectiveness in minimizing future stroke events, superior temporal artery-medial cerebral artery (STA-MCA) bypass remains an essential treatment for complex giant intracranial aneurysms, tumors, moyamoya disease with ischemia, and atherosclerotic steno-occlusive disease with hemodynamic cerebrovascular insufficiency. The objective of this report is to describe a novel suturing technique for STA-MCA bypass that helps reduce donor-recipient anastomosis time, allowing for a well-organized systematic workflow. ⋯ We describe a novel technique for interrupted STA-MCA bypass suturing that adds efficiency, safety, organization, and operative ease compared with the conventional method of interrupted vessel suturing.
