Distal Thrombectomy for Acute Anterior Circulation Stroke with Chronic Large Vessel Occlusion.
Endovascular therapy has been increasingly recommended for the treatment of acute ischemic stroke with large vessel occlusion of the anterior circulation. However, occlusions of the distal cerebral artery are not uncommon and may cause clinical deficits, especially when combined with ipsilateral chronic large vessel occlusion. Therefore in this patient population, the recognition of chronic occlusion and recanalization of the distal occlusive artery might be of great value for flow compensation. ⋯ The recognition of chronic occlusion is crucial during acute mechanical thrombectomy, and distal thrombectomy may be beneficial after a careful full-scale assessment.

Plaque characteristics play pivotal roles in ischemic events, but stenosis severity does not accurately reflect carotid plaque volume due to expansive remodeling in some patients with low-grade stenosis (LGS). This study aimed to assess the safety, efficacy, and durability of carotid endarterectomy (CEA) for symptomatic LGS. ⋯ CEA represents a safe and feasible therapeutic option for a subset of patients with symptomatic LGS.

The purpose of this study was to identify predictors of 30-day postoperative pulmonary complications after open reduction and internal fixation (ORIF) of vertebral fractures. ⋯ Early identification of risk factors for postoperative pulmonary complications is important in the evaluation of patients with vertebral fractures for surgical decision-making, preoperative optimization, and subsequent postoperative care to improve patient outcomes and minimize morbidity.

Fast and secure access to intracranial vessel occlusion is essential for mechanical thrombectomy (MT) in the treatment of acute ischemic stroke. We compared 2 intermediate distal access catheters (DAC: Distal Access Catheter [C1] and SOFIA: Soft torquable catheter Optimized For Intracranial Access [C2]) for procedural speed and safety of MT as well as clinical outcome at discharge and after 90 days. ⋯ The use of C2 resulted in reduced procedural times with less stent-retriever maneuvers. Clinical outcome at discharge was better for C2 catheters, whereas no significant difference of outcome was apparent after 90 days.

Posterior atlantoaxial fusion is an important armamentarium for neurosurgeons to treat several pathologies involving the craniovertebral junction. Although the potential advantages of recombinant human bone morphogenetic protein-2 (rhBMP-2) are well documented in the lumbar spine, its indication for C1-C2 fusion has not been well characterized. In our institution, we apply rhBMP-2 to the C1-C2 joint either alone or with hydroxyapatite, locally harvested autograft chips, and/or morselized allogenic bone graft for selected cases-without conventional posterior structural bone graft. We report the clinical outcomes of the surgical technique to elucidate its feasibility. ⋯ Although retrospective and from a single center, our study has shown that rhBMP-2 usage at the C1-C2 joint without posterior structural bone grafting is a safe and reasonable surgical option.
