Filter by:Cannulation of complex arteriovenous fistula (AVF) or graft (AVG) is a challenge to renal nurses. Ultrasound (US) guidance on central and peripheral venous access visualisation has been widely adopted in nephrology and shown to reduce complications of vascular interventions. With broader adoption of handheld US devices in clinical services, renal nurses could acquire this point-of-care technique to increase the successful cannulation rate while facilitating confidence build-up during training and practice. We aim to evaluate the use of handheld US on difficult AVF/AVG cannulation in a hospital-based dialysis unit.
The infection rate of thoracic endovascular aortic repair (TEVAR) is unknown due to a lack of epidemiological data. The rate currently available comes from researches conducted decades ago, when open surgery was the standard of care. Because of the potentially fatal consequences of a stent graft infection in the thoracic aorta, the investigators tend to prescribe antibiotic prophylaxis for at least three days. In this study, the investigators are going to collect data on patients receiving TEVAR in the past five years and provide the following information: a. the infection rate (MAGIC classification), b. the rate of fever, c. the results of the lab tests, such as the WBC count and C-reaction protein. d. risk factors associated with infection and fever.
Chronic subdural hematomas (CSH) are collections of blood in the subdural space. CSH are becoming the most common cranial neurosurgical condition among adults, and a significant public health problem, due to an increasing use of anticoagulant and antiplatelet medication in an ageing population. Symptomatic CSH, or CSH with a significant mass effect, are treated surgically. However, recurrences are common (10 to 20%). Conservative management (medical) is used in patients who are asymptomatic or have minor symptoms. However, therapeutic failures, requiring surgical treatment, are common. The pathophysiology of CSH involves inflammation, angiogenesis, and clotting dysfunction. Self-perpetuation and rebleeding is thought to be caused by neo-membranes from the inflammatory remodeling of the dura-mater mainly fed by the distal branches of the middle meningeal artery (MMA). There are 13 ongoing registered RCTs in CSH, with the most common covering application of steroids, surgical techniques and tranexamic acid. Further to this, there are trials running on other pharmacological agents, and peri-operative management. Some industrial or academic trials are or will enroll in France in the next year in France. But to our best knowledge, none of these trials will the eventual benefits of the MMA embolization in both cases of medical and/or surgical management, and none will focus on the use of cyanoacrylates (CYA) for this purpose. Preliminary case series and nonrandomized retrospective studies have suggested that MMA embolization alone or as adjuvant therapy to surgery can decrease recurrences. The investigators hypothesize that in both conditions of conservative or surgical managements, endovascular embolization of patients with CSH significantly reduces the risk of recurrence of CSH. The investigators choose the CYA as liquid embolic agent because of the pain and cost of the use of Ethylen Vinyl alcohol copolymer (EVOH) agents and its simplicity to be used.
Patients with a chronic subdural hematoma (cSDH), that is, a blood accumulation between two meninges developing over a long period of time, often have recurrent bleedings after an initial operation. The study aims to show that additional surgery reduces the risk of recurrent bleeding. The additional procedure aims to block small blood vessels in the skull with tiny plastic particles. The small blood vessels are embolized using X-rays and a contrast medium and a fine tube that is inserted into the diseased vessels of the head via the groin. Patients of full age who have undergone burr hole trepanation as a first operation, i.e. a blood drain through a hole in the cranial cavity, can participate in the study. Participating patients are randomly assigned to a control group with treatment according to clinical routine or a treatment group with an additional occlusion of the blood vessels in the skull. In addition, patients can consent to a genetic test to determine the relationship between a coagulation factor and the risk of recurrence of the hematoma. In order to record the test results, check-up examinations are carried out after one and three months.
The ENDOBARC-S post-market clinical follow-up study is undertaken to evaluate the prevention of death related to aortic arch pathologies when treated by branch stent graft systems (Nexus stent-graft system®, Relay Branch® or Zenith arch branch graft®), with proximal landing at zone 0. The secondary objective is to evaluate the safety and clinical performance of the studied devices.
PacePress medical device, by ensuring constant compression force and the ability to optimize it in the pocket area prevents/significantly reduces the risk of hemorrhagic complications, including but not limited to the operation pocket hematoma. By avoiding a strong localized compression and ensuring "covering compression" achieved by the appropriate distribution of compression forces on the entire implantation site area, with an automated compression force control, the risk of a pressure sore created in the compressed pocket area is reduced.
The SWEMMA trial is an open, national, multi-center, prospective, randomized (1:1), superiority trial designed to assess impact on reoperation rates for chronic subdural hematoma with a head-to-head comparison of embolization of the middle meningeal artery (intervention) with standard neurosurgical hematoma evacuation (control).
Most primigravida is confronted with episiotomy during childbirth to prevent the perineal and vaginal lacerations which could be performed at birth. There are many types of episiotomy which are median, mediolateral, and J-shaped episiotomy. Prevention of the formation of the dead space during the repair of episiotomy so avoiding hematoma formation in the episiotomy area after child-birth. The Mostafa Maged four-stitch technique uses absorbable vicryl threads with round needles 75 mm.
Chronic subdural hematomas (CSH) are one of the most frequent pathologies in emergency neurosurgical practice. Standard therapy for symptomatic CSH is surgical drainage. However, the recurrence rate after surgery is high (10 to 20% in the most of series, although it has been reported from 2 to 37%). Middle meningeal artery embolization (MMAE) is a promising minimally invasive procedure that has recently been proposed as an alternative or adjunctive treatment to surgery. The investigators hypothesize that early post operative endovascular treatment can reduce the recurrence rate in high-risk patients, improving neurological outcomes by reducing the need for reinterventions, hospitalizations, and post-operative complications. The aim of the investigators is to analyze the efficacy of and safety of early post-surgical embolization of MMA in reducing the risk of CSH recurrence.
