Spinal cord monitoring during intraspinal extramedullary tumor operations (Peroneal nerve evoked responses)
1990
Longterm scalp recording of early SEP components triggered by peroneal or tibial nerve stimulation detects functional disturbances of spinal cord transmission due to mechanical trauma. We confirm previous observations that preoperative SEP patterns reflect neurological deficits and clearly show functional disturbances even on the side where they are not manifest. Peroneal nerve SEP have a well-known P40-peak corresponding to activities of neurons at the postcentral cortical layers. The P40-peak was identified in only 55% of our recordings. We therefore, tried to use the P50-peak that could be identified in 100% of the recordings under the difficult recording circumstances in the operating r…
Endonasal Approach for Nasal and Paranasal Sinus Tumor Removal
2001
Patients with benign (53) and malignant (22) tumors of the nose and paranasal sinuses were treated for tumor removal via an endonasal approach. Patient selection was based on tumor location (centrally) rather than histology. Tumors attainable by the endonasal approach were located in the nasal cavity, the ethmoid sinus, the sphenoid sinus and the medial wall of the maxillary sinus. Endonasal microscopic techniques including endonasal orbital decompression and endonasal closure of CSF-leaks were combined with surgical navigation tools in selected cases. Surgical trauma and morbidity could be minimized without compromising radicality of tumor removal. Postoperative hospitalization was compara…
Effect of Corticosteroids on Facial Function after Cerebellopontine Angle Tumor Removal: A Double-Blind Study versus Placebo
2015
The aim of this study was to assess the effect of corticosteroids administered intra- and postoperatively on the occurrence of facial palsy after a cerebellopontine angle (CPA) tumor resection, and to investigate pre- and intraoperative prognostic factors. A multicenter, prospective, randomized, double-blind and versus-placebo study was conducted between 2006 and 2010. Three hundred and ten patients operated on for a CPA tumor (96% vestibular schwannomas, 4% miscellaneous) were included by five participating centers. The population was stratified into patients with small (≤15 mm CPA on axial MRI views) and large tumors. In each group, patients were randomized to receive corticosteroid (1 mg…
Intraoperative imaging findings in transcranial MR imaging-guided focused ultrasound treatment at 1.5T may accurately detect typical lesional finding…
2020
To assess the intraoperative neuroimaging findings in patients treated with transcranial MR-guided focused ultrasound (tcMRgFUS) thalamotomy using 1.5T equipment in comparison with the 48-h follow-up.Fifty prospectively enrolled patients undergoing unilateral tcMRgFUS thalamotomy for either medication-refractory essential tremor (n = 39) or Parkinson tremor (n = 11) were included. Two radiologists evaluated the presence and size of concentric lesional zones (zone I, zone II, and zone III) on 2D T2-weighted sequences acquired intraoperatively after the last high-energy sonication and at 48 h. Sonication parameters including number of sonications, delivered energy, and treatment temperatures …
Doppler and B-mode ultrasound for avascular nephrotomy.
1983
AbstractDoppler sonography for intraoperative localization of the intrarenal arteries combined with B-scan sonography for intraoperative visualization of stones allows complete stone removal via small radial nephrotomies for which clamping of the renal artery is no longer necessary. Since September 1980 we used this technique on 35 patients with staghorn or recurrent calculi. The main advantages of this technique are exact and quick stone localization, minimal loss of renal function owing to preservation of the intrarenal vascular system, and no need for renal ischemia and cooling.
Surgical outcomes of diaphragmatic resection during cytoreductive surgery for advanced gynecological ovarian neoplasia: A randomized single center cl…
2022
Introduction: Ovarian cancer (OC) represent nearly 4% of gynecologic malignancies and it is often diagnosed at advanced stage. Diaphragmatic surgery, a fundamental step of advanced stage ovarian cancer (ASOC) debulking surgery, is associated with a high post-operative complication incidence, which is supposedly reduced with thoracostomy tube placement. We assessed the role of intra-operative thoracostomy tube placement, as a prevention measure for post-operative complications, after diaphragmatic resection. Methods: This was a single center prospective randomized trial. Ovarian cancer patients, who underwent mono-lateral diaphragmatic resection, were randomized 1:1 into two arms. Arm A incl…
Complement split products and proinflammatory cytokines in intraoperatively salvaged unwashed blood during hip replacement: comparison between hepari…
2008
Background and Objectives The aim of the present study was to investigate the quality of shed blood collected in a new intraoperative autotransfusion system (Sangvia®, AstraTech, Sweden) and to study whether heparin-coated surfaces in the device reduce the production of inflammatory mediators. Material and Methods The study was randomized and prospective. Twelve total hip arthroplasty patients whose blood was collected with a device having a heparin-coated surface and 12 patients whose blood was collected with a device having a non-heparin-coated surface were included. Venous blood was drawn from the patients preoperatively. Intraoperatively 200 ml salvaged blood was collected and samples…
A novel device for intracolonoscopy cleansing of inadequately prepared colonoscopy patients: a feasibility study.
2019
Abstract Background The importance of high quality preprocedural bowel preparation is widely acknowledged, but suboptimal bowel cleansing still occurs in up to 20 % of all colonoscopy patients. The aim of this study was to evaluate the performance of a novel intraprocedural cleaning device for cleaning poorly prepared colons. Methods This multicenter feasibility study included patients aged 18 – 75 years who were referred for colonoscopy. Intraprocedural cleaning was performed in patients after a limited preprocedural bowel preparation regimen (2 days of dietary restrictions and 2 × 10 mg bisacodyl). The primary outcome was the proportion of adequately prepared patients (Boston Bowel Prepar…
