Hereditary hemorrhagic telangiectasia can manifest itself with pulmonary arteriovenous malformations (pavm). A transcatheter coil embolization should be made to avoid complications and to close off relevant arteriovenous shunts. We report on a patient with expectoration of embolization coils 15 years after embolotherapy. In case of hemoptysis following embolotherapy with coils, even years after their placement one should consider coil migration into the pulmonary system, besides newly formed pavms, in the differential diagnosis and initiate contrast-CT of the thorax and bronchoscopy.

Mechanical ventilation (MV) is an essential part of modern intensive care medicine. MV is performed in patients with severe respiratory failure caused by insufficiency of the respiratory muscles and/or lung parenchymal disease when/after other treatments, i. e. oxygen, body position, secretion management, medication or non invasive ventilation have failed. In the majority of ICU patients weaning is routine and does not present any problems. ⋯ The target audience for this guideline are intensivists, pneumologists, anesthesiologists, internists, cardiologists, surgeons, neurologists, pediatricians, geriatricians, palliative care clinicians, nurses, physiotherapists, respiratory therapists, ventilator manufacturers. The aim of the guideline is to disseminate current knowledge about prolonged weaning to all interested parties. Because there is a lack of clinical research data in this field the guideline is mainly based on expert opinion.

Case Reports Comparative Study
[Cerebral microhaemorrhage as imaging correlate of high-altitude cerebral edema in a patient under long-term ventilation].
Within the scope of a cerebral magnetic resonance imaging to diagnose a dysphagia in a patient on long-term artificial respiration, the morphological criteria for a HACE (high-altitude cerebral edema) have been met. We found microangiopathic white matter lesions in the area of the corpus callosum and splenium, characteristic features of a HACE. ⋯ The exact pathophysiology is still not known but hypoxia seems to be the triggering stimulus. Thus the question arises: long-term ventilated patients suffering from severe gas exchange disorders develop constellations which are equivalent to HACE?

We report a 75-year old female patient with advanced emphysema. After endoscopic lung volume reduction with endobronchial valves (EBV), a huge pneumatocele has occured and resolved spontaneously within a few weeks. Albeit rare, pneumatoceles should be considered in patients with relapsing dyspnoe after EBV treatment.
