Endovascular Treatment of Spontaneous and Isolated Infrarenal Acute Aortic Syndrome with Unibody Aortic Stent-Grafts
2020
Abstract Introduction Spontaneous acute aortic syndrome (IAAS) is rarely localized in the infrarenal aorta. The endovascular approach is preferred over conventional open surgery with fewer complications. However, dedicated endovascular devices for IAAS treatment are unavailable. The aim was to report a large single-center experience using unibody stent-grafts to address IAAS. Methods From April 2016 to March 2019, a retrospective analysis of patients presenting spontaneous and isolated IAAS was performed. Patients addressed with the unibody stent-graft (AFX endovascular AAA system; Endologix Inc., Irvine, CA) were included in the study. Indications to IAAS treatment were persistent symptoms…
Drug eluting and bare metal stents in people with and without diabetes: Collaborative network meta-analysis
2008
Objective To compare the effectiveness and safety of three types of stents (sirolimus eluting, paclitaxel eluting, and bare metal) in people with and without diabetes mellitus. Design Collaborative network meta-analysis. Data sources Electronic databases (Medline, Embase, the Cochrane Central Register of Controlled Trials), relevant websites, reference lists, conference abstracts, reviews, book chapters, and proceedings of advisory panels for the US Food and Drug Administration. Manufacturers and trialists provided additional data. Review methods Network meta-analysis with a mixed treatment comparison method to combine direct within trial comparisons between stents with indirect evidence fr…
The risks of using continuous deep palliative sedation within the context of euthanasia
2016
Although palliative care is one of the main arguments among the opponents of euthanasia, the individual medical activities implemented within it are not always evaluated unequivocally. Considering that patient in such care centres arrives mainly at the last stages of the disease when intensive treatments are no longer able to help, to reduce discomfort and relieve pain caused by the disease, analgesic means can be used that can shorten the patient's life expectancy and cause death. Such undesirable consequences can be seen in the deep and continuous palliative sedation, which not only is the last resort for pain prevention process, but also is still quite debatable medical and legal doctrin…
Minimally invasive procedures for the management of vertebral bone pain due to cancer: The EAPC recommendations.
2015
Image-guided percutaneous ablation methods have proved effective for treatment of benign bone tumors and for palliation of metastases involving the bone. However, the role of these techniques is controversial and has to be better defined in the setting of palliative care.A systematic review of the existing data regarding minimally invasive techniques for the pain management of vertebral bone metastases was performed by experts of the European Palliative Care Research Network.Only five papers were taken into consideration after performing rigorous screening according to inclusion and exclusion criteria (low number of patients, retrospective series, proceedings).According to the present data …
Safety and Feasibility of Robotic-Assisted Drainage of Symptomatic Pancreatic Pseudocysts: A Case-Series Analysis (with video).
2021
Background: The surgical treatment of pancreatic pseudocysts (PPs) in patients who fail nonoperative management has evolved from aggressive open to a minimally invasive approach. The application of robotic surgery in this setting is scarcely reported. The aim of this study is to analyze the safety and feasibility of the robotic approach to pancreatic pseudocyst drainage. Methods: A single centre retrospective review of consecutive patients undergoing robotic-assisted pancreatic pseudocyst surgeries in an academic tertiary institution was performed. Results: There were 14 patients studied, of whom 10 underwent cystogastrostomy and 4 Roux-En- Y cystojejunostomy. Eight patients had gallstone p…
Restoring Neurological Physiology: The Innovative Role of High-Energy MR-Guided Focused Ultrasound (HIMRgFUS). Preliminary Data from a New Method of …
2017
Background Tremor is a disabling condition, common to several neurodegenerative diseases. Lesioning procedures and deep brain stimulation, respectively, of the ventralis intermedius nucleus for intentional tremor, and of the subthalamic nucleus for parkinsonian resting tremor, have been introduced in clinical practice for patients refractory to medical treatment. The combination of high-energy focused ultra-sound (HIFUS) with sophisticated magnetic resonance (MR) instrumentation, together with accurate knowledge of the stereotactic brain coordinates, represents a revolution in neuromodulation. Methods At the Neurosurgical Clinic and the Radiology Department of the University of Palermo,, tw…
Quantitative study of muscle fibre atrophy and restitution after nerve grafts.
1976
Our comparative experimental studies on rabbits using clinical, electromyographical, and quantitative histological examinations of long autologous and homologous nerve grafts in 35 rabbits, paying special attention to quantitative histological changes in the gastrocnemius muscles, allow the statement that, compared to the short homografts, the long homografts showed worse results. Moreover, it became obvious that the regeneration rate of autografts was not influenced by increasing the lengths of the grafts. The answer to the question of how far even longer grafts may influence the quality of regeneration will need further investigations.
The histology and immunohistochemistry of free buccal mucosa and full-skin grafts after exposure to urine
1999
Objective To investigate the histological and immunohistochemical behaviour of free buccal mucosa and full-skin grafts after exposure to urine. Materials and methods A buccal mucosal graft and a full-skin graft were freely transferred into the bladder of 12 minipigs, after stripping the bladder mucosa. Endoscopic investigations were carried out 2 and 5 months after surgery, and the grafts examined after death at 7 months, both histologically and immunohistochemically. Results Shrinkage of the full-skin graft was apparent endoscopically in five cases. Of the nine full-skin grafts, four showed severe inflammatory reactions, two necrosis and two ulcerations. Conversely, the 10 buccal mucosal g…
A survey on current practice in the neurosurgical management of preterm infants with posthemorrhagic hydrocephalus in Germany.
2012
Background and Study Aims Different approaches to the management of preterm infants with posthemorrhagic hydrocephalus (PHH) are described in the literature. Likewise, neurosurgical and pediatric surgical departments in German hospitals use different methods to treat these patients. The aim of this study was therefore to assess the current situation regarding the management of PHH, which is a first and essential step toward the development of standards of practice. Patients and Methods In the second half of 2009, we sent standardized questionnaires to 139 neurosurgical departments (number of returned questionnaires: 98) and 73 pediatric surgical departments (returned questionnaires: 62) t…
