Endoscopic neurosurgery has now not but reached the protection and applicability of microsurgery. Endo-neuro-sonography is a brand new strategy aimed toward making endoscopy more secure by way of real-time imaging and navigation capability (brain-radar). The endo-neurosonographic photo is a sonographic experiment on the tip of the endoscope (mini-CT) delivering additional info to the endoscopic view. Endo-Neuro-Sonography is the 1st booklet in this new subject, featuring recommendations and gear, anatomical positive aspects, and the 1st medical sequence. Schematic drawings, tables and 237 figures (122 in colour) provide an exact review of this system. the ultimate bankruptcy is facing destiny strategies on minimally invasive neurosurgery and particular connection with ergonomics in neurosurgery.

Transendoscopic Ultrasound for Neurosurgery

Endoscopic neurosurgery has now not but reached the security and applicability of microsurgery. Endo-neuro-sonography is a brand new approach geared toward making endoscopy more secure by means of real-time imaging and navigation ability (brain-radar). The endo-neurosonographic photograph is a sonographic test on the tip of the endoscope (mini-CT) delivering more information to the endoscopic view.

Moyamoya Disease

The 1st point out of moyamoya sickness as a unique illness entity used to be in a paper I released in 1965. The irregular internet­ like vessels on the base of the mind visible in cerebral angio­ grams of this disorder have been defined by way of so much local audio system of jap as "moyamoya," a jap expression for a few­ factor hazy, similar to a pant of cigarette smoke drifting within the air.

106 Conclusions . . . . . . . . . . . . . . . . . . . 109 Intraoperative endoneurosonographic (ENS) imagings prepared during surgery on 52 selected patients between April 1996 and July 2000 were examined. There were 23 female and 29 male patients, and their mean age was 42 (2–69) years. In most cases Aloka (Aloka Deutschland, Düsseldorf, Germany) sono equipment was used because equipment supplied by this company had yielded superior imaging results in Objective After transendoscopic sono-catheters had been tested in the laboratory for imaging characteristics and practicability (chap.

The parallel presentation of both images on one screen regardless of head position makes working and correlation of the two images much easier 49 General Remarks and List of Lesions General Remarks and List of Lesions In clinical use the sono-catheter has superior imaging and navigation abilities to those seen in anatomical laboratory work. Real-time and online characteristics represent changes such as shifting, pulsation, CSF flow, and changes in size and form of structures. When confronted with clinical problems, this technique still has some limitations.

Thoracic spinal canal scan. The sono-probe (1) is placed in the thoracic spinal subarachnoid space (2) dorsal to the medulla (3) and close to a network of arachnoid membranes (<), surrounded by the bony border of the canal (4) Suprasellar and Retrosellar Space. When the subarachnoid space and the cisterns are to be imaged, endoscopy must be accompanied by irrigation, as the sono-probe needs a liquid medium to show up any findings. In the example presented the scope is inserted through a lateral supraorbital burr hole approaching the chiasmatic cistern with both optic nerves.
