[Interventional radiology as emergency therapy].

CLINICAL ISSUE: Both the progress of surgical techniques and the demographic development with increasing numbers of multimorbid patients demand and also encourage radiology in the setting of trauma and acute emergencies. In addition to a fast and precise diagnostics, this also includes image-guided, minimally invasive therapy to control and treat several acute pathologies. STANDARD RADIOLOGICAL PROCEDURES: Computed tomography (CT) is not only important for the diagnosis of abscesses, active bleeding or other acute pathologies, but also allows minimally invasive therapy. While digital subtraction angiography (DSA) guides catheter-based procedures, e.g., to control bleedings or to place percutaneous transhepatic cholangiodrain (PTCD), fluoroscopy allows the 3D-visualization to drain abdominal and thoracic abscesses. METHODOLOGICAL INNOVATION AND EVALUATION: Radiology has established itself in the treatment of acute emergencies or acute complications through gentle and usually fast minimally invasive procedures. Presumably, MRI interventions will become increasingly important in the near future and, thus, complement the portfolio. PRACTICAL RECOMMENDATIONS: Every clinical radiologist who works on night shifts should be able to safely carry out some basic interventional techniques in order to stabilize the patient and at least ensure medically safe bridging to the next routine workday. Due to the diversity of materials and the rarity and difficulty of some procedures, the full portfolio requires years of expertise and will therefore remain restricted to specialized interventional radiologists.
