Brief Summary in Lay Language

Intracerebral or intraventricular hemorrhages can be detected via computer tomographies (CT)or magnetic resonance imaging (MRI) .
All patients, so are participants of this study, are treated according to standards of the Departements of Neurology and Neurosurgery of the University Hospital of Freiburg and according to the guidelines of the German Stroke Association; participating in this study does not change therapy measures.
All patients receive a second CT-scan due to those standards, usually 3-7 days after occurence of the bleeding.
The aim of the study is to picture and measure the hemorrhage via transcranial sonography. Therefore, a transcranial sonography is performed on day 1 and the following days until the day of the second CT-scan. The localisation and volume of the hemorrhage is measured in all diagnostic mediums and compared. Therefore, sonographic pictures are evaluated by 2 different neurologists, CT- and MR-scans by a neuroradiologist. The aim is to show that transcranial sonography is a safe, precise and examiner-independent in intracerebral or intraventricular hemorrhages.

Brief Summary in Scientific Language

Via transcranial sonography it is possible to display cerebral structures and their pathologies. Especially, the ventricular system and the third ventricle can be displayed well and sonographies of the ventricular width correlate sufficiently with computer tomographies (CT; (Becker et al. 1994, Seidel et al. 1995, Kiphuth et al. 2011). Pathologies, such as intracerebral bleedings, can be depicted sufficiently via transcranial sonography (Seidel et al. 1995, Kukulska-Pawluczuk et al. 2012). Furthermore, the sonographic measurement of the size and volume of the hemorrhage correlate with values of CT-scans (Marti-Fabregas et al. 2005, Niesen et al. 2006, Perez et al. 2009). Therefore, transcranial sonography is a bed-side tool for follow-up of intracerebral hemorrhages (Perez et al. 2009) and diseases affecting the wifth of the third ventricle (Kiphuth et al. 2011).
The transcranial sonography shows several advantages compared to CT- or magnetic resonance imaging (MRI)- scans: it prevents patients' transports, is not based on x-rays, and can be used in agitated patients due to its shorter examination time Perez et al. 2009, Ovesen et al. 2014).
INtraventricular hemorrhages can be depicted sufficiently as hyperechogenic structures (Mäurer et al. 1998, Kukulska-Pawluczuk et al. 2012).
Systematic studies of changes of echogenicity of venrricular bleedings do not exist so far. However, we suggest that transcranial sonography is a safe method for intraventricular bleedings as it is for intracerebral bleedings (Seidel et al. 1993).
This study aims to show that the transranial sonography is a safe, sufficient and examiner-independent method to display ventricular hemorrhages and their course of echogenicity.
In the future, CT-scans could be scheduled and their number even reduced according to sonographic measurements.

Interventions/Observational Groups

  •   A transcranial sonography is performed in all patients with intraventricular or intracerebral hemorrhage displaying the ventricular system and hemorrhage. Sonography is performed every day until the second CT-scan. Results of ultrasound and CT- or MRI-scans are compared regarding echogenicity of the third ventricle, the Graeb-Score and the hemorrhage volume.
