Benefits of adapting minimal invasive techniques to selected patients with spontaneous supratentorial intracerebral hematomas.

Objectives: This study assesses the benefits of adapting minimal invasive techniques (MIT) to selected patients with spontaneous supratentorial intracerebral hematomas (SSICHs).

Methods: The study compares the post-operative residual clot volume and clinical outcome of 89 selected, MIT evacuated SSICH-patients to those of 138 unselected cases operated in our department. Selection criteria includes patient age, early admission and MIT treatment.

Hyperacute measurement of brain-tissue oxygen, carbon dioxide, pH, and intracranial pressure before, during, and after cerebral angiography in patients with aneurysmatic subarachnoid hemorrhage in poor condition.

Background: The objective of this study was to examine early changes of intracranial pressure (ICP) and brain oxygenation before, during, and after cerebral angiography in patients with poor-grade subarachnoid hemorrhage (SAH).

Methods: Fourteen patients with poor-grade SAH without intracerebral hematoma were studied. A significant change in monitored variables (arterial gases, ICP, brain-tissue oxygen pressure [Ptio(2)], brain-tissue carbon dioxide pressure, and pH) was defined as a register deviation of more than 20% compared with the baseline.

Evaluation of invasiveness and efficacy of 2 different keyhole approaches to large basal ganglia hematomas.

Background: The aim of this study was to evaluate the invasiveness and efficacy of 2 different keyhole approaches to large basal ganglia hematomas (LBGHs).

Methods: The invasiveness and efficacy of the temporal (15 cases) and the frontal (15 cases) microsurgical keyhole approach were retrospectively evaluated in 30 early-operated patients with LBGH, using recorded neuronavigation data. Invasiveness was assessed calculating the angles of brain retraction and the volume of brain exposed to surgery.
