Most endovascular thrombectomy patients have Target Mismatch despite absence of formal CT perfusion selection criteria.

Endovascular thrombectomy (EVT) is the standard of care for large vessel occlusion stroke. Use of Computed Tomographic Perfusion (CTP) to select EVT candidates is variable. The frequency of treatment and outcome in patients with unfavourable CTP patterns is unknown.

Balloon assisted Woven endobridge deployment (BAWD): A safety and efficacy study.

Background: Balloon-assisted deployment/remodelling is a proven adjunctive technique for coil embolization of intracranial aneurysms, and it may be a helpful adjunct in delivering the Woven EndoBridge (WEB) device.

Objective: To evaluate the safety, efficacy and feasibility of balloon-assisted WEB deployment in both ruptured and unruptured intracranial aneurysms in both typical and atypical locations.

Methods: Patients who underwent treatment of ruptured and unruptured intracranial aneurysms with the BAWD technique were retrospectively identified from a prospectively maintained database at two neurointerventional centres.

Would you bet on PET? Evaluation of the significance of positive PET scan results post-microwave ablation for non-small cell lung cancer.

Fluodeoxyglucose-positron emission tomography (FDG-PET) imaging is an acknowledged modality for the follow-up of solid tumours treated with thermal ablation, with persistent or new FDG uptake at the ablation site considered to be a reliable indicator of local recurrence. Several cases of proven false-positive FDG-PET scans are illustrated in this pictorial essay with uptake at the site of the ablated tumour, remote from the ablated lesion and in mediastinal and hilar lymph nodes. Positive FDG-PET scans post-thermal ablation of lung tumours therefore cannot always reliably predict local tumour recurrence or nodal spread.
