Minimally invasive surgery combined with increased use and accuracy of preoperative CT scans has changed the clinical management of acute appendicitis in elderly patients, leading to decreased lengths of stay, decreased mortality, and more favorable outcomes.
Higher rates of postoperative stroke and inpatient mortality for women undergoing CAS is an unexpected finding, and may indicate that this population is vulnerable to complications after endovascular management. Low volume is a predictor of complications and subsequent mortality primarily for CAS. Patients who undergo CEA continue to have superior outcomes compared with matched cohorts who undergo CAS.
Neurosurg Focus 40 (4):E14, 2016M any sports-related brain injuries involve mild traumatic brain injuries (mTBIs), which result from physical blows to the head sustained over a period of time. Sports associated with an increased risk of head injury include American football, ice hockey, soccer, rugby, the martial arts, boxing, and bicycling. 21,90 These injuries are often unrecognized, undiagnosed, or underreported, which reflects the fact that this is a growing medical concern, often labeled a "silent epidemic." 8,66 Chronic exposure to mild brain injuries can result in long-term neurological consequences and represents a spectrum of disorders. The most remarkable outcome of mTBI is termed chronic traumatic encephalopathy (CTE), a clinical syndrome that is associated with neurodegeneration and behavioral, cognitive, and/or motor deficits. Although this disease has distinct pathological features, CTE is considered a diagnosis of exclusion because only postmortem biopsies can confirm the diagnosis. Therefore, new diagnostic methods need to be developed to: 1) inform patients of a definitive diagnosis, 2) better understand the epidemiology and risk factors of the disease, and 3) implement intervention programs to prevent any potential long-term complications. This review examines how understanding the pathology and molecular changes associated with repeated head trauma can lead to the discovery of novel imaging techniques and biomarkers. Mild Traumatic Brain Injury and CTEChronic traumatic encephalopathy has evolved from the so-called punch-drunk syndrome, which was used to describe a distinct neuropsychiatric condition that seemed to affect boxers, eventually becoming known as dementia pugilistica during the 1920s and 1930s.

Early detection and management of brain injuries in sports are of utmost importance in preventing chronic neurological and psychiatric decline. These types of injuries incurred during sports are referred to as mild traumatic brain injuries, which represent a heterogeneous spectrum of disease. The most dramatic manifestation of chronic mild traumatic brain injuries is termed chronic traumatic encephalopathy, which is associated with profo...
There is a temporal association between the societal guidelines' recommendations regarding VCF placement and the actual rates of insertion. More uniform consensus statements from multiple societies along with the use of level I evidence may be required to lead to a definitive change in practice.
We describe a case of concomitant fibromuscular dysplasia (FMD) and atherosclerotic internal carotid artery (ICA) disease in a symptomatic patient. Sixty-eight-year-old female presented for evaluation of a transient ischemic attack. Imaging revealed severe proximal >80% ICA stenosis with severe FMD to mid and distal ICA. Planned hybrid approach with left carotid endarterectomy (CEA) and balloon angioplasty was aborted intraoperatively due to lack of back bleeding. Open gradual rigid dilation was then performed with resumption of back bleeding. Completion angiogram revealed widely patent flow through CEA patch with no residual defects. Patient awoke from operation neurologically intact. At 6-month follow-up, carotid duplex revealed severe recurrent ICA stenosis. Endovascular intervention was performed with balloon dilation to the proximal and mid-ICA with stenting of a moderate 60% ostial common carotid stenosis. She recovered well from procedure with 3-month carotid duplex showing widely patent common carotid stent and ICA with no areas of stenosis. Informed consent has been obtained from the patient for publication of the case report and accompanying images.
BACKGROUND AND IMPORTANCE Pseudoaneurysms involving the superficial temporal artery (STA), either iatrogenic or caused by direct trauma, are rare. The STA is prone to injury due to its long course throughout the scalp. Injuries can cause cosmetic defects and/or skin breakdown leading to further complications. CLINICAL PRESENTATION We report a case of delayed iatrogenic pseudoaneurysm of the STA after placement of an intracranial pressure monitor in the setting of acute traumatic brain injury. The patient had a delayed development of a pulsatile mass over his right frontal region, with computed tomography angiography concerning for a pseudoaneurysm of the STA. This was managed with surgical resection with complete resolution of symptoms at follow-up. CONCLUSION We review the literature regarding the etiology, pathogenesis, and management of these lesions. While iatrogenic injuries to the STA have been previously reported, this is a curious case related to placement of an intracranial pressure monitor. We recommend direct surgical resection of the pseudoaneurysm for cosmetic effect and prevention of further wound breakdown.
through record review. Study end points were major adverse limb events (MALE), major amputations (AMPU), amputation-free survival (AFS) and mortality. Statistical analysis was performed using the Cox-proportional hazards model.Results: A total of 1906 lower extremity procedures were performed in 957 limbs with PAD; 622 patients (males, 363; females, 259) with a mean age 67.8 years, (range, 27-98). These included 713 open, 610 endovascular), and 75 hybrid revascularizations; and 192 primary and 340 secondary amputations. Half the procedures (52%) were performed for critical limb ischemia (CLI) and 7% were emergencies. The study population was predominantly white (96%); comorbidities included dyslipidemia in 62%, coronary artery disease in 47%, 26% with a prior intervention, current smoking in 42%, diabetes mellitus in 37%, and renal insufficiency (serum creatinine >2.0 mg/dL) in 8%. On univariate analysis the most significant risk factor associated with MALE and AMPU was presence of CLI (hazard ratio [HR], 3.1/7.1), followed by renal insufficiency on dialysis (HR, 3.2/5.2), emergency procedure (HR, 3.0/2.5), diabetes mellitus (HR, 2.0/3.9), and congestive heart failure (HR, 1.9/3.4). The prevalence of significant obesity (body mass index >35 kg/m 2 ) increased from 6% in the 5
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
