Comparative StudyComparison of frame-based and frameless stereotactic hematoma puncture and subsequent fibrinolytic therapy for the treatment of supratentorial deep seated spontaneous intracerebral hemorrhage.
This study compared the technical implications and clinical outcome of patients treated for an intracerebral hemorrhage using two minimally invasive procedures: frame-based stereotactic hematoma aspiration and frameless navigation-guided hematoma aspiration followed by fibrinolysis. ⋯ The frame-based group and the frameless group followed by fibrinolysis had similar outcomes, and both procedures effectively reduced the intracerebral hemorrhage volume within a short period of time. In addition, these procedures are simple, precise, safe, and brief with a very low rebleeding rate and mortality.

Case ReportsVirtual 3-dimensional preoperative planning with the dextroscope for excision of a 4th ventricular ependymoma.
Advances in computer imaging and technology have facilitated enhancement in surgical planning with a 3-dimensional model of the surgical plan of action utilizing advanced visualization tools in order to plan individual interactive operations with the aid of the dextroscope. This provides a proper 3-dimensional imaging insight to the pathological anatomy and sets a new dimension in collaboration for training and education. ⋯ Virtual reality has brought new proportions in 3-dimensional planning and management of various complex neuroanatomical problems that are faced during various operations. Integration of 3-dimensional imaging with stereoscopic vision makes understanding the complex anatomy easier and helps improve decision making in patient management.

Accurate placement of ventricular catheters decreases the incidence of proximal catheter failure. The use of a frameless, interactive neuronavigational system can optimize catheter placement. ⋯ Frameless neuronavigation in the placement of ventricular catheters assures accurate catheter placement, thereby decreasing the incidence of proximal catheter failure. The absence of rigid head fixation allows additional cohorts to benefit from the apparatus. The use of the electromagnetic system provides a safe, simple, and easy adjunct to optimal catheter placement.

Neuronavigation-assisted surgery for distal anterior cerebral artery aneurysm.
We present our experience with the neuronavigation system used for surgery of distal anterior cerebral artery (DACA) aneurysms. ⋯ Although current neuronavigation systems are not available for all intracranial aneurysms, we believe that the DACA aneurysm is a good candidate for its use. The additional benefits of a small craniotomy and precise intraoperative orientation during surgery result in a minimally invasive aneurysm procedure.

The aim of this study was to evaluate the clinical results of patients who underwent resection with the aid of microsurgical techniques and stereotactic and image-guided surgery for critically located cavernous malformations which still represent a considerable surgical challenge due to the close proximity of vital and eloquent structures. ⋯ Stereotactic methods together with image-guidance and microsurgical techniques allow the creation of most effective and safe corridors to access the CMs in eloquent regions with a minimization of tissue manipulation and low risk of permanent neurological deficit.
