We describe a higher magnifying power operating microscope system to improve one method of high-quality microsurgical clipping for cerebral aneurysm in some cases. This higher magnification is achieved by a new lens design in the optical system, which makes the image of the object very clear at high magnifications (distinctiveness of 7 μm). This higher-resolution operating microscope system provides the surgeon with higher-magnified images (at the maximum of more than 30× magnifications as each working distance) in the operating field. The magnifications can be changed from low power (2.9×) to high power (62.0×) depending on the circumstances in a given procedure. We have used this operating microscope system on 11 patients with microsurgical clipping for cerebral aneurysms. Microsurgical treatment could be performed safely and precisely. All aneurysms were treated without any technical complications. We think that the use of this microscope would have potential benefits for microsurgical treatment for cerebral aneurysms because of better visualization.

もやもや病は、内頸動脈終末部における進行性の狭窄を特徴とし、その周辺にもやもや血管とよばれる異常血管網の発達を伴う疾患である。もやもや病は小児、成人を問わず発生して、脳虚血発作や頭蓋内出血をきたす。現在、唯一の有効な治療法は脳血行再建術である。もやもや病合併妊娠は、脳虚血発作や頭蓋内出血のリスクを高めるため、特に未治療例では頭蓋内出血による生命予後、機能予後の悪化に注意が必要である。妊娠中は妊娠高血圧症候群を回避すること、適切な分娩法を選択することが重要である。もやもや病合併妊娠に対しては、産科医と脳神経外科医が緊密に連携しながら管理すべきである。(著者抄録)

BACKGROUND: The bayonet-shaped spring surgical instrument is essential and perhaps the most important tool in microneurosurgery. It is needed to be handled gently, and so stable handling to the spring tension of the long instrument handle is necessary for fine action in narrow and deep operative fields under an operating microscope. METHODS: A bayonet spring microsurgical instrument handle with a bar as a stabilizer is presented for facilitating delicate microsurgical manipulations stably in microneurosurgery. The bar with the handle is a metric projection. The grip of this instrument is a modified writing grasp, which is composed of writing grasp and sandwiching a lateral-projected bar with handle between the medial side of the index finger and the lateral side of the middle finger. Then, this bar as a stabilizer of the instrument is suitable to fix it. RESULTS: Microneurosurgical operations using this instrument system were performed. This was advantageous to stabilize the instrument in deep and narrow operative fields, to be sensitive to move its functional tips by fingertips, and to reduce unwanted movements under an operating microscope. This was disadvantageous to limit the rotational movement within fingers. There were no complications. CONCLUSION: This handle would provide a steady and balanced grip to ensure precise manipulation of the functional tips of the bayonet instrument for microneurosurgery. It may be useful particularly for the beginners or for the non-dominant hand of microsurgeons.

Supermicrosurgery has been developed and reported the anastomosis of vessels with diameters of about 0.5 mm or less. The anastomosis of vessels of about 0.5 mm or less in diameter is technically more difficult than 1.0 mm or larger. This article describes a novel practice card model for acquiring basic supermicrosurgical techniques. A practice card is composed of very small-caliber silicone tubes simulating very small-caliber vessels and a thick paper. The silicone tube external diameters are 0.3, 0.5, or 0.7 mm. The thickness of the tube wall is 0.05 mm. Microsurgeons can easily begin to practice and warm up the supermicrosurgical suturing and anastomosing techniques using this nonvital practice card under a personal desk stereomicroscope in the office and an operating microscope in the operating room. This training model is a simple system for practicing basic supermicrosurgical techniques repeatedly and for warming up before a supermicrosurgical operation. This article also describes basic training regarding its use at high magnifications. This training-based supermicrosurgical skill may become a valuable technique for microsurgeons in many specialties.

BACKGROUND: We report a safe and precise technique of microvascular anastomosis at higher magnifications (30 - 50 ×) in neurosurgery and evaluate our experiences to examine the utility of this method for cerebral revascularization in various situations. METHODS: A retrospective review was carried out of patients who underwent microvascular anastomosis using a high-magnified operating microscope. This method was performed in 30 patients with 35 microvascular anastomoses in various situations. This microscope has two optical systems, a standard zooming system and a newly developed high magnification system. High resolution and good depth of focus are achieved by a new lens design in the optical system, which makes the image of the object very clear at higher magnifications. In this operating microscope, the combination of a 10 × eyepiece and the 200, 250, and 300-mm objective lens enables a range of final magnifications from 2.9 × to 50.4 ×. RESULTS: This method enabled one to pay attention to performing atraumatic manipulations of small vessels and correct suturing, intima-to-intima, of vessel walls. Microvascular anastomoses were performed safely and precisely at higher magnifications. All anastomoses were patent. CONCLUSION: It is obvious that practical final magnifications of more than 30 × in neurosurgery would be super-magnified operative views. Microvascular anastomosis at 30 - 50 × magnifications (super-microvascular anastomosis) can help neurosurgeons to improve their skills, with good visualization, and to be safe and accurate when conducting cerebral revascularization in various situations.

Previous neurophysiological and behavioral studies relate hippocampal functions to place learning and memory, and encoding of task (or context)-specific information. Encoding of both task-specific information and own location is essential for episodic memory and for animals to navigate to reward-related places. It is suggested that different neural circuits with different assemblies of different hippocampal neurons are created in different environments or behavioral contexts for the hippocampal formation (HF) to encode and retrieve episodic memory. To investigate whether synchronous activity of hippocampal neurons, suggesting functional connectivity between those neurons, is task and position dependent, multiple single unit activities were recorded during performance of real and virtual translocation (VT) tasks. The monkey moved to one of four reward areas by driving a cab (real translocation) or by moving a pointer on a monitor. Of 163 neuron pairs, significant peaks in cross-correlograms (CCGs) were observed in 98 pairs. Most CCGs had positive peaks within 50 ms. Task-dependent cross-correlations (CCRs) were observed in 44% of the neuron pairs, and similarly observed in both the real and VT tasks. These CCRs were frequently observed in pyramidal vs. pyramidal neuron pairs with positive peak and peak shift. However, no consistent patterns of peak polarity, peak shift, and neuronal types were seen in task-independent CCRs. There was no significant difference in frequency of CCG peaks between real and VT tasks. These results suggest that the task-dependent information may be encoded by interaction among pyramidal neurons, and the common information across tasks may be encoded by interaction among pyramidal neurons and interneurons in the HF. These neuronal populations could provide a neural basis for episodic memory to disambiguously guide animals to places associated with reward in different situations.

Donor artery dissection is a known cause of technical failure in microvascular anastomosis. A method for detection and direct repair of donor artery dissection before superficial temporal artery (STA) to middle cerebral artery (MCA) anastomosis is described using a high magnification operating microscope (maximum 50.4× magnification). Before STA-MCA anastomosis, the stump of the STA is stained using methylrosaniline chloride (pyoctaninum blue) and is observed under higher magnifications. Microsurgical suturing of the arterial dissection is performed before the anastomosis procedure under the high magnification microscope. This method was used in two patients with symptomatic hemodynamic cerebrovascular occlusive disease. Postoperative angiography revealed good patency and no complications occurred. This method may be useful for detection and direct repair of arterial dissection in small vessel walls before STA-MCA anastomosis.

A 62-year-old female complaining of sudden severe headache was referred to our stroke center in consultation. Computed tomography showed diffuse spread of thick subarachnoid hemorrhage to the basal cistern and both sylvian fissures, and digital subtraction angiography showed kissing aneurysms arising in the left lateral and occipital directions in the C(1) portion of the internal carotid artery (ICA). The anterior choroidal artery was situated between the two aneurysms, and another small branch originating from the dome of the distal aneurysm was confirmed as a duplicated middle cerebral artery (MCA). Endovascular treatment was successfully performed to spare the two vessels involved. This case of kissing aneurysms and ICA-duplicated MCA is very rare, and presents difficulties for both surgical and endovascular treatments.

BACKGROUND: We report a precise technique for EC-IC bypass surgery using a stereoscopic high-resolution microscope at magnifications of 40x and 50x. METHODS: A stereoscopic operating microscope (Mitaka MM50 Surgical Microscope; Mitaka Kohoki Co, Tokyo, Japan) was used in STA-MCA anastomosis. This microscope has 2 optical systems, a standard zooming system, a newly developed high-magnification system, and 4 fixed working distances of 200, 250, 300 and 350 mm, with highest magnifications of 50.4x at 200 mm and 40.3x at 250 mm. High resolution is achieved by a new lens design in the optical system, which makes the image of the object very clear at high magnification. The magnification can be changed depending on the circumstances in a given procedure. The STA-MCA anastomoses were performed using this microscope. RESULTS: Very small vessels were observable, and arterial anastomosis could be performed precisely at high magnification. All anastomoses were patent on postoperative angiograms. CONCLUSIONS: Use of the new microscope allows visualization and manipulation of small vessels at high magnification and high resolution and may be very useful in EC-IC bypass surgery.
