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.","thumbnailUrl":"https://sni-digital-videos.s3.amazonaws.com/articles/044f3a68-d710-492d-a0cc-59980ee6e8b0/featured/hero-1782421058678.png","publishDate":"2011-01-24T00:00:00.000Z","doi":"10.4103/2152-7806.76143","categories":["Original Article"],"fullTextUrl":"https://surgicalneurologyint.com/api/articles/044f3a68-d710-492d-a0cc-59980ee6e8b0/pdf"}
