Filter by:Background: Chronic subdural hematoma (cSDH) is a type of intracranial bleeding, predominantly affecting the elderly and males, with an estimated incidence of 8/100.000. The collection of subdural fluid expands slowly, leading eventually to brain tissue compression that results in neurological impairment such as seizures, cognitive decline, and paresis. Most patients need neurosurgical evacuation of the blood to improve and to prevent further, possibly permanent deterioration. Evidently, the cause of such a bleeding must be investigated and if possible treated, or preventive strategies need to be installed if possible. Spinal cerebrospinal fluid (CSF) leaks are a known cause of cSDH but are widely underdiagnosed in this population. The spinal CSF leak causes CSF loss that leads to intracranial hypotension, expansion of intracerebral veins, and traction to the brain and the surrounding tissues. A cSDH is a severe complication of such a leak and occurs in about 30% of all cases with a predominance among the elderly. It is crucial to identify these patients with a spinal leak as treatment pathways differ essentially from patients without a leak. Some smaller studies indicated a prevalence of spinal CSF leaks among cSDH patients of 30% to 80% depending on selection criteria (age, extend of cSDH). Notably, the entity of the CSF-venous fistula, that has been discovered as recent as 9 years ago, and that by now is accounting for 20-25% of all spinal leaks, has not been considered in previous research on cSDH and spinal CSF leaks. Currently, there is no prospective data on spinal CSF leaks in patients with cSDH. Establishment of such data is crucial to improve diagnostic and therapeutic algorithms for spinal CSF leaks in patients with cSDH. Objective: To prospectively assess the prevalence of spinal CSF leaks in patients with cSDH Methods: This is a prospective observational, monocentric study on patients admitted due to cSDH to the Department of Neurosurgery at the Medical Center of the University of Freiburg. Treatment and diagnostic procedures will follow standard protocols. The number of spinal CSF leaks will be assessed to generate the prevalence of spinal CSF leaks in this patient cohort. Furthermore, clinical data, the specific type of the CSF leak, and imaging parameters are assessed systematically to estimate the diagnostic value of these measures.
This study was designed to compare the outcome of 3 point with 1 point lightweight mesh fixation in TAPP surgery for patients with inguinal hernia. The main outcome include seroma, chronic pain, recurrence, et al.
A prospective, multicenter, randomized controlled, open-label, blinded endpoint evaluation study.
The purpose of this study was to evaluate if wound drains could influence postoperative spinal epidural hematoma (POSEH) in biportal endoscopic spinal surgery (BESS) procedures for decompression of lumbar spinal stenosis.
Embotrial-1 is an Italian multicenter prospective randomized clinical trial with open-label treatment and blinded outcome assessment (PROBE) to assess the superiority of MMA embolization compared to conservative treatment. The intervention group is MMA embolization and comparator control group is the conservative management with best medical treatment. Patients are randomized 1:1.
The goal of this observational study was to evaluate the safety and acceptability of the ShangRing device for male circumcision among men in Shinyanga, Tanzania. The main question aims to answer both provider acceptability (practicality of device use and placement and removal times) and client acceptability (comfort during placement and removal, experience while wearing the ring, and penile appearance after healing). Participants voluntarily underwent male circumcision using the ShangRing device and before being discharged, were interviewed about their experience. Participants were also interviewed at device removal day (day 7), during a follow-up phone call (day 10), a sample were selected to participate in in-depth interviews (day28), and finally all men were asked to return for a follow-up visit (day 49).
This study will investigate the effectiveness of analgesia of ultrasound hematoma block compared to 'blind' hematoma block in patients with dislocated distal radius fracture.
This multi-center retrospective cohort study aims to investigate the real-world outcomes of chronic subdural hematoma treated with MMAE, including clinical effectiveness, recurrence rates, and safety profile.
Distal radial access (DRA) in the anatomical snuffbox (AS) is a relatively novel approach that can be considered an alternative to trans radial access (TRA) for coronary procedures. Several observational and randomized studies have established its feasibility and safety, with evidence of certain advantages over TRA, such as a reduction in hemostasis time, a lower incidence of complications at the puncture site, and a lower incidence of radial artery occlusion (RAO). Notwithstanding that a recent randomized study reported a similar RAO rate between DRA and TRA, several meta-analyzes confirm the advantages of DRA, despite a consistently higher crossover rate. The objective of this observational study is to assess the performance of the procedure and to compare clinical characteristics in an all-comer population undergoing diagnostic or interventional coronary procedures. The main questions it aims to answer are: - Determine the success rate of DRA and measure the incidence of RAO in an all-comer population undergoing coronary procedures. - Compare the clinical and anatomical characteristics of patients with DRA for coronary procedures and determine predictors of failure of access.
Chronic Subdural Hematomas (cSHD) are common, and due to cerebral compression, often result in neurological impairment and reduced consciousness. Surgery is typically performed once neurological symptoms develop. Recent studies suggest that arteries nourished by the middle meningeal artery (MMA) may be responsible for hematoma progression and that MMA embolization is clinically useful. There is less evidence, that embolization of MMA also may be a treatment option for individuals without surgical treatment. The investigators propose a multicentre study to investigate both potentials: (1) Assessment of efficacy of embolization after surgery to reduce recurrence and improve outcomes by conducting a randomized trial (randomization arms; Arms 1 and 2), (2) Assessment of embolization-alone efficacy when surgery is contraindicated or refused (embolization-only arm, Arms 3 and 4).
