Randomized Controlled TrialEnhancing ablation effects of a microbubble-enhancing contrast agent ("SonoVue") in the treatment of uterine fibroids with high-intensity focused ultrasound: a randomized controlled trial.
To evaluate the role of the ultrasound contrast agent SonoVue in enhancing the ablation effects of ultrasound-guided high-intensity focused ultrasound (HIFU) on uterine fibroids. ⋯ Based on the results of this randomized controlled trial, SonoVue could be safely used to enhance the effects of HIFU treatment for uterine fibroids.

Case ReportsCT-guided injection of N-butyl cyanoacrylate glue for treatment of chylous leak after aorto-mesenteric bypass.
Lymphangiography and thoracic duct embolization are well-described techniques for the diagnosis and treatment of thoracic lymphatic leaks refractory to conservative treatment. However, thoracic duct embolization is not an option in patients with abdominal chylous leaks. ⋯ Ultrasound-guided intranodal lymphangiography demonstrated a retroperitoneal lymphatic leak tracking along the vascular graft into the peritoneal cavity. Computed tomography-guided lymphatic duct occlusion with N-butyl cyanoacrylate glue was performed, resulting in successful treatment of both chylothorax and chylous ascites.

Case ReportsPercutaneous embolization of a chylous leak from thoracic duct injury in a child.
Postoperative chylous leak may result from thoracic duct injury during surgical procedures in the chest or neck and can be successfully treated with percutaneous embolization. We report the case of a child with persistent chylothorax and chyloperitoneum following multivisceral transplantation, which was performed due to unresectable inflammatory myofibroblastic tumor of the retroperitoneum. Intranodal lymphangiography was used to demonstrate the site of chylous leak from the lower segment of the thoracic duct and the leak resolved within days following percutaneous embolization of the thoracic duct.

Endovascular repair of ruptured abdominal aortic aneurysm: technical and team training in an immersive virtual reality environment.
This study evaluates a fully immersive simulated angiosuite for training and assessment of technical endovascular and human factor skills during a crisis scenario. ⋯ This study shows feasibility of creation of a crisis scenario in a fully immersive angiosuite simulation and team performance of a simulated rEVAR. Performance metrics differentiated between experienced specialists and trainees, and the realism of the simulation exercise and environment were rated highly by experienced endovascular specialists. This simulation has potential as a powerful training and assessment tool with opportunities to improve team performance in rEVAR through both technical and human factor skills training.

ReviewMechanical thrombectomy with stent retrievers in acute ischemic stroke.
Mechanical thrombectomy (MTE) in patients with acute ischemic infarct caused by large-vessel occlusion is becoming used with increasing frequency in many stroke centers. With the introduction of stent retrievers, recanalization rates >80 % are reached by most operators. ⋯ In this review, the indications for MTE, the technique, and the technical and clinical outcomes are discussed. Complications and predictors for good clinical outcome are described based on recent data from the literature.
