Ureteral injury during left colectomy for cancer: Laparoscopic management. A case report
2020
Abstract Introduction Iatrogenic ureteral lesions may occur after any abdominal and pelvic surgery. They are severe and can affect renal function and even vital prognosis. This study aimed to determine the clinical aspects and the therapeutic approaches of a lower third injury of the ureter during a laparoscopic left colectomy. Presentation of case An 81 year-old-man with left-sided colon cancer underwent laparoscopic left colectomy. During surgery there was a continuous full-thickness solution of the left ureter for which an end-to-end ureteral anastomosis was performed. In the postoperative period the patient underwent multiple urological and radiological interventional procedures due to …
Rationale and design of the EMBRACE STEMI Study: A phase 2a, randomized, double-blind, placebo-controlled trial to evaluate the safety, tolerability …
2012
Background Although significant efforts have been made to improve ST-segment elevation myocardial infarction (STEMI) outcomes by reducing symptom-onset-to-reperfusion times, strategies to decrease the clinical impact of ischemic reperfusion injury have demonstrated limited success. Bendavia, an intravenously administered mitochondrial targeting peptide, has been shown to reduce myocardial infarct size and attenuate coronary no-reflow in experimental modelswhen given before reperfusion. Design The EMBRACE STEMI study is a phase 2a, randomized, double-blind, placebo-controlled trial enrolling 300 patients with a first-time anterior STEMI and an occluded proximal or mid–left anterior descendin…
Managing Persistent Hypoxemia: what is new?
2017
Mechanical ventilation is the standard life-support technique for patients with severe acute respiratory failure. However, some patients develop persistent and refractory hypoxemia because their lungs are so severely damaged that they are unable to respond to the application of high inspired oxygen concentration and high levels of positive end-expiratory pressure. In this article, we review current knowledge on managing persistent hypoxemia in patients with injured lungs.
Dilation of the ductus venosus by stent implantation increases placental blood perfusion in fetal sheep.
2006
The reduction of resistance to flow in the ductus venous (DV) and a decrease of blood supply to the liver serve for the survival of the fetus during hypoxia. The present study investigated the influence of the increased diameter of the DV on placental blood perfusion.In 15 ewes with twin pregnancies at gestational ages of 117 +/- 4 days, a stent (4 or 5 mm) was placed into the DV of 1 twin (DV(stent) group) under ultrasound guidance. Blood flow rates in the umbilical vein (UV) and DV of both fetuses were measured using Doppler ultrasound. Eight pairs of twin fetuses were included for the final analysis.The dilatation of the DV increased the blood flow volume rate passed through the DV from …
Endoscopic management of gastric outlet obstruction disease
2019
Gastric outlet obstruction (GOO) is a clinical syndrome characterized by a variety of symptoms. It may be caused by motor disorders and by benign or malignant mechanical disease. Endoscopic management of benign disease is mainly based on balloon dilation, augmented by the use of covered self-expanding metal stents (SEMS) in refractory disease. Endoscopic ultrasound-guided gastroenterostomy (EUS-GE) is increasingly used as an alternative method, although more studies with longer follow up are needed before it can be considered as a recommended therapy. Surgery remains the last resort. Endoscopic management of malignant GOO is based on SEMS placement as an alternative to palliative surgery, b…
An International, Multicenter Retrospective Observational Study to Assess Technical Success and Clinical Outcomes of Patients Treated with an Endovas…
2022
Introduction: Type III endoleaks post-endovascular aortic aneurysm repair (EVAR) warrant treatment because they increase pressure within the aneurysm sac leading to increased rupture risk. The treatment may be difficult with regular endovascular devices. Endovascular aneurysm sealing (EVAS) might provide a treatment option for type III endoleaks, especially if located near the flow divider. This study aims to analyze clinical outcomes of EVAS for type III endoleaks after EVAR. Methods: This is an international, retrospective, observational cohort study including data from 8 European institutions. Results: A total of 20 patients were identified of which 80% had a type IIIb endoleak and the r…
Endovascular Repair of Contained Abdominal Aortic Aneurysm Rupture Using a Bilateral D-Shaped Stent System

Endovascular management of a large aneurysm of the superior vena cava involving internal thoracic vein with remodeling technique
2016
International audience; We report a case describing endovascular treatment of a large aneurysm of the superior vena cava involving internal thoracic vein. The goal of this case report is to highlight the contributing role of embolization with remodeling technique in such an exceptional condition.
Patient- and lesion-tailored algorithm of endovascular treatment for arterial occlusive disease of extracranial arteries supplying the brain: safety …
2017
Introduction: Although surgical endarterectomy remains the treatment of choice for carotid artery stenosis, stenting plays an important role as an alternative treatment modality, especially in high-risk patients. The actual safety profile associated with stenting procedures is probably better than that reported by randomized controlled trials. Aim : To assess the safety of stent implantations in extracranial arteries supplying the brain, and also to identify risk factors associated with this procedure. Material and methods: This was a post hoc analysis, with 30-day follow-up. We analyzed the results of treatment of 372 patients who underwent 408 procedures, 197 such procedures in asymptomat…
Optimal application of compressive palatal stents following mesiodens removal in pediatric patients:a Randomized Controlled Trial
2021
Background There is no scientific evidence supporting the choice of a palatal stent in patients who underwent removal of an impacted supernumerary tooth. We aimed to investigate the effects of palatal stents in patients who underwent supernumerary tooth removal through a palatal approach and to suggest the optimal stent thickness and material. Material and Methods We recruited 144 patients who underwent extraction of a supernumerary tooth between the maxillary anterior teeth. Subjects were assigned to a control group (CG) or one of four compressive palatal stent groups (CPSGs) classified by the thickness and material of the thermoplastic acrylic stent used. Palatal gingival swelling and obj…
