A microscissors device for us in microvascular end-to-side anastomosis, and an end-to-side vascular anastomotic repair technique are disclosed. The microscissors device standardizes the excision in a recipient (arterial or venous) vessel wall so that a hemodynamically sound anastomosis can be achieved. In order to form the standardized excision, a microscissors device has pivoting arms providing a scissors-action with cooperating half-moon shaped sharpened indentations in the pivoting arms which engage and form the uniform excision in the recipient vessel wall. The end-to-side vascular anastomotic repair technique includes the step of forming a standardized generally longitudinally extending excision in the recipient vessel wall to facilitate insertion and subsequent suturing of the donor vessel, in a hemodynamically sound manner. The excision is made as uninterrupted single-step excision. Also, the excision is formed essentially within the confines of the recipient vessel wall without extending substantially across the passageway of the recipient vessel.
