• Numerous interventional techniques have been used to embolise brain arteriovenous malformations (AVMs). • This prospective multicentre study demonstrates the suitability of a liquid embolic agent. • The safety of treatment using Onyx is acceptable. • Such embolisation leads to complete AVM occlusion in 23.5 % of patients.

Long-term treatment with the oncolytic ECHO-7 virus Rigvir of a melanoma stage IV M1c patient, a small cell lung cancer stage IIIA patient, and a histiocytic sarcoma stage IV patient-three case reports. APMIS 2016; 124: 896-904 Oncolytic virotherapy is a recent addition to cancer treatment. Here, we describe positive treatment outcomes in three patients using Rigvir virotherapy. One of the patients is diagnosed with melanoma stage IV M1c, one with small cell lung cancer stage IIIA, and one with histiocytic sarcoma stage IV. The diagnoses of all patients are verified by histology or cytology. All patients started Rigvir treatment within a few months after being diagnosed and are currently continuing Rigvir treatment. The degree of regression of the disease has been determined by computed tomography. Safety assessment of adverse events graded according to NCI CTCAE did not show any value above grade 1 during Rigvir Ò treatment. Using current standard treatments, the survival of patients with the present diagnoses is low. In contrast, the patients described here were diagnosed 3.5, 7.0, and 6.6 years ago, and their condition has improved and been stabile for over 1.5, 6.5, and 4 years, respectively. These observations suggest that virotherapy using Rigvir can successfully be used in long-term treatment of patients with melanoma stage IV M1c, small cell lung cancer stage IIIA, and histiocytic sarcoma stage IV and therefore could be included in prospective clinical studies.

Background Bridging treatment with intravenous thrombolysis (IVT) before endovascular thrombectomy (EVT) in acute ischemic stroke is applied under the assumption of benefits for patients with large vessel occlusion (LVO). However, the benefit of this additional step has not yet been proven. Purpose To compare procedural parameters (procedural time, number of attempts), complications, and clinical outcome in patients receiving EVT vs. patients with bridging treatment. Material and Methods In this prospective study all patients had acute anterior cerebral circulation occlusion and were treated with EVT. All patients were selected for treatment based on clinical criteria, multimodal computed tomography (CT) imaging. Eighty-four patients were treated with bridging IVT followed by EVT; 62 patients were treated with EVT only. Results Bridging therapy did not influence endovascular procedure time ( P = 0.71) or number of attempts needed ( P = 0.63). Bleeding from any site was more common in the bridging group (27, 32%) vs. the EVT group (12, 19%) ( P = 0.09). Functional independence modified Rankin Scale after 90 days was slightly higher in the bridging group (44%) vs. the EVT group (42%) ( P = 0.14). Mortality did not differ significantly at 90 days: 17% in the bridging group vs. 21% in EVT alone ( P = 0.57). Both treatment methods showed high recanalization rates: 94% in the bridging group and 89% for EVT alone. Conclusion Bridging treatment in LVO did not show benefits or elevated risks of complications in comparison to EVT only. The bridging group did not show significantly better neurological outcome or significant impact on procedural parameters vs. EVT alone.
