Filter by:Spontaneous cerebral hemorrhage is one of the main causes of death and disability all over the world, accounting for 20%-30% of all cerebrovascular diseases. Minimally invasive surgery of cerebral hemorrhage, especially puncture aspiration, can improve early and long-term neurological recovery in patients with cerebral hemorrhage. Until now, no standardized practice for minimally invasive surgery of spontaneous cerebral hemorrhage has been established. Hematoma puncture and drainage based on CT scans without precise localization and personalized approach design, which may lead to poor efficacy and high risk of complications. Our hospital has much experience in treating cerebral hemorrhage with stereotactic puncture and aspiration. So we conduct a prospective multicenter randomized controlled clinical trial to determine the therapeutic effects of puncture aspiration plus thrombolysis treatment for the perioperative and long-term recovery of patients with small to moderate hematoma in deep basal ganglia via computerized precision coordinates and personalized approach design.
This prospective, double-blind, randomized, placebo-controlled study aims to evaluate the efficacy and safety of atorvastatin in patients with chronic subdural haematoma. The degree of disability or dependence in daily activities, as well as surgical intervention or recurrence, of the treatment and control groups will be compared.
This study will evaluate the feasibility to predict the prognosis of IDA with IMH by DCE-MRI and provide theoretical basis for the prognosis and intervention of the disease.
The objective of this registry is to collect information on the performance and clinical benefits of the AMDS (Ascyrus Medical Dissection Stent) to treat patients with acute "DeBakey type I dissections" and with or without so called "preoperative clinically relevant malperfusion" and/or "intramural hematomas". In a healthy aorta (the vessel that supplies blood to most of the body) the blood flows freely through the main lumen (a space inside the vessel where blood flows). The participants involved in this study have a tear that has separated the inner layer of the aorta wall and created a secondary channel (false lumen) in addition to the main channel (true lumen), and huts, the blood flows through both channels. AMDS is a stent (a metal tube helping to keep the vessel open) that is placed in the descending thoracic aorta. AMDS is a medical device commercially available in the countries in which the study is being conducted and it is used as standard of care according to its indication.
This study aims to reduce the recurrence rate of chronic subdural hematomas (CSDH) by manipulating the post-operative intravenous fluid use. The hypothesis relies on the relationship between osmolality and volume changes related to osmolality. We will be administering dextrose 5% in 1/4 normal saline (D5 1/4NS) post-operatively to induce brain expansion which can take up the residual CSDH space, to help reduce recurrence rate.
This is a pilot study to evaluate the feasibility of conducting a larger trial to determine if the use of intraoperative topical tranexamic acid (TXA) decreases the rate of post-operative hematomas and seromas in breast cancer patients after their mastectomy. In other words, the investigators want to determine if applying TXA inside the surgical wound before it is closed helps reduce blood or serous fluid accumulation at the operative site. Dependent on the results of this study, a further larger trial may or may not take place. Post-operative seromas and hematomas are common complications of mastectomy surgery not only leading to infection, discomfort, wound dehiscence or emergency room visits; they also delay in some instances post-operative adjuvant radiotherapy. Establishing whether or not topical TXA is an effective strategy to decrease those complications can potentially impact positively the breast cancer treatment. To achieve this aim, this randomized pilot study will first determine whether a larger multicenter study if feasible. This study will replicate a formal randomized trial at a smaller scale in a single center in order to assess the recruitment and randomization process, as well as provide preliminary results for our research question.
This study compare general anesthesia versus locoregional anesthesia for evacuation of chronic subdural hematoma. Half of participant will be operated under general anesthesia, while the other half will be operated under locoregional anesthesia.
This study evaluates the necessity of dural tenting sutures in craniotomies. The sutures elevate the dura, a layer between the brain and skull. Supposedly, by doing so, they prevent blood collecting between dura mater and the skull. These blood collections, called epidural hematomas, contributed greatly to postoperative mortality in the early days of neurosurgery. There have been several reports questioning the ongoing need for them in neurosurgery, thanks to modern hemostatic techniques. Moreover, it has been published in the literature, and is a common knowledge as well, that some neurosurgeons do not use these sutures at all, and do not have worse outcomes than their colleagues. In this study, half of the randomly assigned participants will undergo craniotomy without dural tenting sutures and will be considered an intervention group. The other half will undergo craniotomy with these sutures.
Rationale: Chronic subdural hematoma (cSDH) is a frequently occurring disease, occurring mainly in the elderly. Surgical evacuation is effective, but also associated with life-threatening risks. In these old, often frail, patients with multi-comorbidity, surgery also comes with significant risks for future cognitive functioning and therefore, loss of independency. In five small retrospective series, tranexamic acid (TXA), an antifibrinolytic drug, showed a beneficial effect on the spontaneous resolution of the hematoma and, with that, the necessity for surgery. This randomised, placebo-controlled clinical trial aims to prove the efficacy of TXA. Objectives: Primarily to evaluate the efficacy of TXA to prevent surgery for cSDH. Secondarily to evaluate the efficacy of TXA to reduce cSDH volume, neurological impairment (mNIHSS), the incidence of falling incidents, the mortality rate, the use of care and health-related costs (iMCQ and iPCQ), to improve cognitive functioning (MOCA), performance in activities of daily living (Barthel and Lawton-Brody), functional outcome (mRS), the level of quality of life. Study design: Double-blind placebo-controlled multicentre randomized clinical trial. Study population: All patients, age 50 and above, diagnosed with cSDH for whom a conservative treatment is selected as primary treatment strategy. Intervention: The intervention group will receive oral TXA 500mg twice daily for 4 weeks, the control group will receive a placebo twice daily. The TXA or placebo treatment is additional to standard care. Main study endpoint: The number of patients requiring surgery within 12 weeks after start treatment. Nature and extent of the burden and risks associated with participation, benefit and group relatedness: Patients will use the study medication twice daily for four weeks. Follow-up is at 4, 8and 12 weeks with a standard CT-scan of the head, outpatient clinic visits and 4 patient-reported questionnaires. These outpatient clinic visits are standard care; the third CT-scan, the questionnaires and extra clinical tests are extra. Each patient may benefit from the study if the study medication proves effective in preventing surgery for cSDH, whereas the risk of potential side effects of the medication is slight (e.g. the risk of thromboembolic events is only 0.01-0.1%). Surgery remains a possibility for those patients in whom study medication is not effective.
It has been a longstanding teaching in plastic surgery that intra-operative ketorolac use for postoperative pain control increases hematoma and bleeding in breast reduction surgery. However, there is no literature that supports this teaching. Ketorolac is used routinely in free flap reconstruction including breast reconstruction as well as many other surgeries including hand surgery without increased risks of hematoma or bleeding. Ketorolac has been shown to give good postoperative pain control. The object of this study is to look at whether ketorolac increases the rate of hematoma/bleeding in breast reduction. If there is no increased risk of hematoma, then ketorolac can be used safely for postoperative pain control with an increased risk of hematoma/bleeding. Normally, without using ketorolac, the hematoma rates in a breast reduction are 1-2%.
