Short description

Intracranial hemorrhages are a heterogeneous group of diseases that are associated with high mortality, morbidity and constraints. The causes, treatments and courses of the disease show a high variability and may also be affected by preexisting illnesses.

In the spontaneous intracerebral hemorrhage, we investigate a new surgical treatment  called decompressive hemicraniectomy as a part of the prospective international SWITCH Trial. There is also an emphasis on brain edema development as an additional factor in poor outcomes.

For aneurysmal subarachnoid hemorrhages, our focus is on the evaluation of ultrasound for diagnosing and on inhaled nitric oxide therapy for existing vasospasm. Furthermore, in a prospective study we try to improve patient classifications.

In chronic subdural hematomas, we examine patient outcomes depending on intraoperative parameters and postoperative care/imaging.

The Department of Neurosurgery is involved in a variety of retrospective and prospective studies in the field of intracerebral hemorrhage in order to improve treatment outcomes.
