Antagonizing dabigatran by idarucizumab in cases of ischemic stroke or intracranial hemorrhage in Germany - A national case collection.
2017
BackgroundIdarucizumab is a monoclonal antibody fragment with high affinity for dabigatran that reverses its anticoagulant effects within minutes. It may exhibit the potential for patients under dabigatran therapy suffering ischemic stroke to regain eligibility for thrombolysis with rt-PA and may inhibit lesion growth in patients with intracerebral hemorrhage on dabigatran.AimsTo provide insights into the clinical use of idarucizumab in patients under effective dabigatran anticoagulation presenting with signs of ischemic stroke or intracranial hemorrhage.MethodsRetrospective data collected from German neurological/neurosurgical departments administering idarucizumab following product launch…
Conservative Surgical Management of Late Carotid Patch Infection in a Patient with Subsequent Stenting for Restenosis.
2022
Carotid patch infection is a rare but dreaded complication after endarterectomy. About 160 cases can be found in literature, but presentation in a patient with post-endarterectomy stenting has not been reported. Most frequent clinical manifestations include the occurrence of a sinus, a pseudoaneurysm, or neck swelling, but in severe cases it may present anastomosis dehiscence with hematoma or hemorrhage. Usually, patch removal and reconstruction is recommended, but there is not a standard protocol for management. Conservative surgical management with patch preservation has only been reported in a minority of cases. We report a patient with a history of carotid endarterectomy and subsequent…
Early and late mortality of spontaneous hemorrhagic transformation of ischemic stroke.
2014
Background Hemorrhagic transformation (HT), a complication of ischemic stroke (IS), might influence patient's prognosis. Our aim is to evaluate, in a hospital-based series of patients not treated with thrombolysis, the relationship between HT and mortality. Methods We compared mortality of individuals with spontaneous HT with that of individuals without. Medical records of patients diagnosed with anterior IS were retrospectively reviewed. Outcome measures were 30- and 90-day survival after IS onset. Kaplan–Meier estimates were used to construct survival curves. Cox proportional hazards model was used to estimate hazard ratio (HR) for the main outcome measure (death). HT was stratified in he…
Haemodynamic predictors of a penetrating atherosclerotic ulcer rupture using fluid-structure interaction analysis
2013
We present preliminary data on the flow-induced haemodynamic and structural loads exerted on a penetrating atherosclerotic aortic ulcer (PAU). Specifically, one-way fluid-structure interaction analysis was performed on the aortic model reconstructed from a 66-year-old male patient with a PAU that evolved into an intramural haematoma and rupture of the thoracic aorta. The results show that elevated blood pressure (117 mmHg) and low flow velocity at the aortic wall (0.15 m/s(2)) occurred in the region of the PAU. We also found a low value of time-averaged wall shear stress (1.24 N/m(2)) and a high value of the temporal oscillation in the wall shear stress (oscillatory shear index = 0.13) in t…
Spontaneous Cortical Spreading Depression and Intracranial Pressure Following Acute Subdural Hematoma in a Rat
2012
Acute subdural hemorrhage (ASDH) is a frequent and devastating consequence of traumatic brain injury. Tissue damage develops rapidly and makes treatment even more difficult. Management of increased intracranial pressure (ICP) due to extravasated blood volume and brain swelling is often insufficient to control all adverse effects of ASDH. In addition to sheer volume, spontaneously triggered cortical spreading depression (CSD) that leads to cell death following ischemia or trauma may contribute to injury development after ASDH. Therefore, we explored the occurrence of CSD by tissue impedance (IMP) measurement in a rat model subjected to ASDH. IMP and intraventricular and mean arterial pressur…
Acute Subdural Hematoma in Pigs: Role of Volume on Multiparametric Neuromonitoring and Histology
2008
Traumatic brain injury (TBI) is often complicated by acute subdural hemorrhage (ASDH) with a high mortality rate. The pathophysiological mechanisms behind such an injury type and the contribution of blood to the extent of an injury remain poorly understood. Therefore, the goals of this study were to establish a porcine ASDH model in order to investigate pathomechanisms of ASDH and to compare effects induced by blood or sheer volume. Thus, we infused 2, 5, and 9 mL of blood (up to 15% of intracranial volume), and we compared a 5-mL blood and paraffin oil volume to separate out effects of extravasated blood on brain tissue. An extended neuromonitoring was applied that lasted up to 12 h after …
23-hour observation endocrine neck surgery: lessons learned from a case series of over 1700 patients
2017
Although the surgical procedures concerning the thyroid and the parathyroid glands are considered safe, the possible occurrence of complications (mainly hematoma and hypocalcemia) limit the short stay surgery. At our institution a 23-hour-surgery with overnight hospital stay for endocrine neck surgical procedures was introduced since 2004. The present case series analyses the institutional results. Over 1913 endocrine neck surgery procedures, 1730 patients (90,2%) were managed according to this model. Among these patients, 92 suffered from hypocalcemia, 12 from airways obstruction due to the hematoma, 5 from bilateral nerve palsy. 15 more patients had unpredictable general disease compromis…
Vascular complications on arterial puncture site after coronaric and peripheral angiography
2011
Il cateterismo cardiaco, l'angiografia coronarica e periferica e le procedure interventistiche sono tecniche contrastografiche che prevedono la visualizzazione radiografica dei vasi coronarici e periferici dopo l'iniezione selettiva di mezzo di contrasto radiopaco. Si tratta di tecniche relativamente sicure, anche se esiste un certo rischio di morbilità e mortalità. Nel nostro studio abbiamo valutato le varie complicanze mettendole in relazione con fattori demografici e clinici, terapie, caratteristiche della puntura e della procedura.
Emergency Surgery ina a patient with large spontaneous epidurl hematoma determinig exellent neurological recovery: review of the literature
2014
Study Design: Case report Objectives: we report a case of a 75-year-old woman suffering voluminous idiopathic spontaneous spinal epidural hematomas (SSEH) that was rapidly diagnosed and successfully treated Methods: Clinical presentation was characterized by sudden and intense back pain that rapidly evolved into plegia of the right leg and severe paresis of the left leg. Hypoesthesia below T6 and urinary retention were also present. The MRI showed a significant posterior spinal compression from T6 through L3 caused by an epidural hematoma that involved 10 metameric levels, extending for approximately 20 cm, with a maximum thickness of 1.6 cm from T12 to L1. Results: Within 12 hours, emergen…
Oral microbiome and systemic antineoplastics in cancer treatment:a systematic review
2021
Oral mucositis is one of the most common side effects in cancer patients receiving systemic antineoplastics. However, the underlying biological mechanisms leading to this condition are still unclear. For this reason, it has been hypothesised that systemic antineoplastics may cause an imbalance on the oral microbiota that subsequently triggers oral mucosa damage. A systematic review was performed following the PRISMA protocol and the PICO question established was: patients diagnosed with cancer, who are candidates for receiving systemic antineoplastics (P=Patients), that undergo oral microbiome determinations (I=Intervention), before and after systemic antineoplastics administration (C=Compa…
