Percutaneous endoscopic discectomy for far lateral lumbar disc herniations: prospective study and outcome of 66 patients.
Extraforaminal disc herniations represent up to 11% of all lumbar herniated discs. Numerous surgical approaches have been described. Percutaneous endoscopic discectomy (PED) is one of the minimally invasive techniques; after mastering this procedure it is a practical method that is used for treatment of foraminal or extraforaminal disc herniation. The outcome of PED for treatment of foraminal or extraforaminal disc herniation has been studied. ⋯ Percutaneous endoscopic discectomy is a minimally invasive method and offers many benefits to the patient, but extensive surgical practice is needed to become a capable surgeon. Consequently this technique can only be a treatment option on appropriate patients. This study reconfirmed that the removal of fragmented disc material is achieved and offers a pain-free status.

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.

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 ReportsEndovascular stent placement of cervical internal carotid artery dissection related to a seat-belt injury: a case report.
The incidence of carotid artery dissection related to blunt injury is very low, but the mortality rate is high. Rapid diagnosis and proper treatments are discussed. ⋯ Prompt diagnosis without delay and intimate follow-up is the key for the treatment of a carotid injury. Those patients who exhibit cervical bruits and/or seat-belt signs should be examined aggressively. Angioplasty with stents is amenable for patients with traumatic carotid dissections requiring vascular reconstruction in the acute stage.

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.
