This case series describes the use of the Medtronic Micro Vascular Plug (MVP) system in the treatment of acute massive orofacial hemorrhages in patients with cancer and trauma, resulting in successful hemostasis in these emergent cases. ⋯ These cases demonstrate that the MVP as an embolic device is a valuable transarterial embolic treatment option in cases of acute orofacial bleeding where rapid, effective hemostasis is required.

Use of C7 Slope as a Surrogate Marker for T1 Slope: A Radiographic Study in Patients with and without Cervical Deformity.
T1 slope has emerged as an important radiographic parameter in the evaluation and surgical management of adult cervical spinal deformity. Given the high rates of nonvisualization of T1 slope on upright cervical radiographs, however, this study examined the evaluation of C7 slope as a potential surrogate marker. ⋯ Results demonstrated that C7 and T1 were in direct correlation in a variety of different cohorts regardless of deformity status or prior fusion. This study indicates that C7 slope may be reliably used a surrogate marker especially when visualization of T1 slope is not possible.

Extent of resection (EOR) constitutes a crucial factor for patient prognosis in surgery of brain metastases (BMs). According to early studies using postoperative magnetic resonance imaging (MRI), an unexpected residual tumor was not uncommon. Knowledge of potential risk factors for incomplete BM resection would be of major importance to optimize surgical strategies. The aim of this study was to evaluate EOR in a large cohort and analyze potential risk factors for incomplete BM resection. ⋯ Our data indicate that postoperative MRI is able to detect a high portion of unexpected residual tumors after surgery of BMs. Preoperative tumor volume in particular represents an important risk factor for incomplete resection, and hence neurosurgeons should pay special attention to avoid residual tumor tissue.

The impact of household economics on outcomes is not well understood. We examined the relationship of income and surgical outcomes, after controlling for numerous patient characteristics. ⋯ Patients matched on a multitude of characteristics, of lesser household income, had higher long-term mortality after brain tumor resection. Further understanding of this disparity should be sought and differences mitigated.
