Percutaneous tumor ablations are rather safe and effective treatments in selected patients for non-operable non-small cell lung carcinomas or lung metastases. However, there are major complications such as bronchopleural or bronchocutaneous fistula, which it is important to know in order to manage them safely. We describe in this report a case of bronchocutaneous fistula without pneumothorax following a microwave ablation of a recurrent pulmonary metastasis and its management.

A type II endoleak (T2EL) is the most common endoleak after endovascular aneurysm repair (EVAR), and a persistent T2EL has been occasionally associated with aneurysmal enlargement. Typical findings of a T2EL consist of an endoleak cavity with inflow and outflow arteries of aortic branch vessels. However, an atypical T2EL, in which hypertrophied vasa vasorum and enlargement of a thrombosed aneurysm are observed, has no endoleak cavity. We have seen three cases of continuous aortic aneurysmal growth after EVAR caused by atypical T2ELs without endoleak cavities through developed vasa vasorum...

Vertebroplasty and kyphoplasty are minimally invasive techniques applied for the treatment of vertebral fractures. Since not all vertebral compression fractures are the same, a tailored-based approach is necessary for optimum efficacy and safety results. Nowadays, different cements and materials are proposed as alternatives to the original poly-methylmethacrylate aiming to overcome the limitations and the risks governing its use. Both techniques are governed by high efficacy and low complication rates; multilevel treatment in a single session has been shown to be feasible with no compromise of the technique's safety and efficacy...
