OBJECTIVE Extracranial meningioma metastases are uncommon, occurring in less than 1% of patients diagnosed with meningioma. Due to the rarity metastases, not routinely screened for distant disease. In this series, we report their experience and results screening select recurrent meningiomas. METHODS All undergoing resection or stereotactic radiosurgery primary from 2009 2017 at a single center were retrospectively reviewed identify who underwent imaging evaluate systemic metastases. Imaging...
OBJECTIVE Resection of brain metastases (BMs) may be associated with increased risk leptomeningeal disease (LMD). This study examined rates and predictors LMD, including imaging subtypes, in patients who underwent resection a BM followed by postoperative radiation. METHODS A retrospective, single-center was conducted examining overall classic LMD (cLMD), nodular (nLMD) risk. Logistic regression, Cox proportional hazards, random forest analyses were performed to identify factors LMD. RESULTS...
Background: In nipple-sparing mastectomy, adequate perfusion to the nipple-areolar complex (NAC) during reconstruction is paramount avoiding unwanted outcomes. Previous studies have suggested that periareolar incisions may result in higher rates of NAC complications. However, date not specifically investigated this prepectoral reconstruction. The purpose study evaluate impact incision location on complications patients undergoing breast Methods: We performed a retrospective review all who...
High-value medical care is described as that leads to excellent patient outcomes, high satisfaction, and efficient costs. Neurosurgical in particular can be expensive for the hospital, substantial costs are accrued during operation throughout postoperative stay. The authors developed a "Safe Transitions Pathway" (STP) model which select patients went postanesthesia unit (PACU) then neuro-transitional (NTCU) rather than being directly admitted neurosciences intensive (ICU) following...
Summary A combination of surgical emphysema, bilateral pneumothorax, pneumomediastinum and pneumoperitoneum complicating anaesthesia using endotracheal intubation has been reported only once before. Its occurrence twice in a recent period 4 months at one hospital suggests that it may not be rare. Recognition the early signs should enable steps to taken before irreversible cerebral damage occurred.
OBJECTIVE The authors’ institution is in the top 5th percentile for hospital cost nation, and neurointensive care unit (NICU) one of costliest units. NICU more expensive than other units because lower staff/patient ratio equipment necessary to monitor patient care. differential between Neuro transitional (NTCU) $1504 per day. goal this study was evaluate pilot a program improve efficiency by modifying postoperative patients who have undergone craniotomy, sending them NTCU as opposed NICU....
Recurrent invasive skin cancer of the scalp and calvarium is a difficult problem for which universally accepted treatment protocols have not been established. The authors present their 10-year experience with this specific subset reconstruction patients successful algorithm that well suited to patient population.The retrospectively reviewed all microsurgical performed from 2005 2015 involved cutaneous malignancies calvarium.Eleven met inclusion criteria. There were 9 squamous cell carcinoma,...
Background Posterior fossa craniotomies can be complicated by cerebrospinal fluid (CSF) leaks, infection, meningitis, neurologic deficits, and intracranial hypotension caused defective closure of the dura. Secondary dural closures such as pericranial graft, muscle glue, sealants, or fat graft are used. However, there have been few studies examining use sealants with a polyethylene glycol polyethylenimine component. Objective We studied effect one sealant, Adherus® (HyperBranch Medical...
Immediate tissue expander placement in postmastectomy breast reconstruction can be complicated by seroma or infection, requiring further imaging studies interventions. This study compares dual-port expanders, with both an aspiration and expansion port, single-port expanders terms of postoperative complications interventions.Patients immediate from March 2019 to 2020 were reviewed. Complications included seroma, hematoma, necrosis, malposition the expander. Further intervention aspiration,...
The Optune® transducer array (Novocure Ltd., Haifa, Israel) is an FDA-approved noninvasive regional therapy that aims to inhibit the growth of glioblastoma multiforme (GBM) cells via utilization alternating electric fields. Some patients with GBM may develop hydrocephalus and benefit from subsequent shunt placement, but special attention must be paid in whom programmable valves are utilized, given potential effect magnetic fields on valve settings. We present first case report illustrating...
Abstract BACKGROUND Molecular characterization of meningiomas has led to new WHO criteria and improved risk stratification. Molecularly high-risk are at elevated recurrence, but anatomic patterns recurrence after resection, which could inform surgical planning or design postoperative radiotherapy (RT), poorly understood. MATERIAL AND METHODS This is a study 23 patients (median age 61, interquartile range [IQR] 51-67, 61% female) who underwent primary resection molecularly meningioma as...
Abstract BACKGROUND Conventional post-operative radiotherapy (RT) after resection of intermediate risk meningioma requires daily outpatient treatment for 6 weeks or more, which impose logistic and financial burdens on patients the healthcare system. Although shortened course hypofractionated radiosurgery (hypoSRS) over 3 to 5 days has been applied intact WHO grade 1 imaging-defined meningiomas, no studies report hypoSRS targeting cavity gross total (GTR) meningiomas. To address this...
Meningiomas are more common in females and 70–80% express the progesterone receptor. They have been reported after gender reassignment therapy, suggesting that high-dose exogenous estrogen/progesterone exposure, such as occurs during fertility treatments, may increase risk of developing a meningioma. The goal this study was to report incidence prior treatment consecutive series female patients presenting with A retrospective review meningioma from 2015–2018 conducted. Female treatments were...
Background: Meningioma metastases are rare, with an estimated incidence of 1 in 1000 quoted the literature. While cases to lungs, liver, vertebrae, distant cranial sites, and other locations have been reported, they so uncommon that patient's rarely screened for metastases. Unlike WHO Grade I meningiomas, III meningiomas can be very aggressive, invading locally, our experience, metastasizing cranial, as well extra-cranial sites. Recently, patients treated at institution began undergoing...
Ependymomas are rare neuroepithelial tumors which may arise anywhere along the ventricular system. Tumors arising in 4th ventricle present unique challenges. Complete tumor resection favors prolonged survival, but result inadvertent injury of surrounding neural structures –such as cranial nerve (CN) nuclei. Here, our institutional experience with surgical 4thventricular ependymomas is described. A single institution, retrospective analysis consecutive case series adult surgically resected...
e13526 Background: Although tumor boards are well-established for coordinating care of patients (pts) with cancer in the outpatient setting, few studies have evaluated interventions improving consultative coordination hospitalized pts, where can be particularly complex. This study hypothesis that implementation an inpatient co-rounding model including medical-, neuro-, and radiation-oncology consult teams would improve alignment recommendations from these oncologic services, as perceived by...
