Straight needle with fingertip support technique reduces exclusion time during bypass (in vitro, in vivo animal study): A technical note

摘要

Background: The duration of exclusion time of recipient artery is an important factor in bypass surgery of cerebral revascularization. The longest period of exclusion is the suturing time. The fingertip support technique (first published in 2006) reduced the physiological tremor to speed up this extra-precise microsurgical procedure. The use of a straight needle proved to further decrease suturing time during the bypass procedure. Methods: A straight micro needle was added to the fingertip support method for further reduction of exclusion time. A comparative study, measuring the duration of suturing time in vitro and in vivo for animal cases, was performed. This was a golden opportunity to examine how to simplify vascular transposition, using the fingertip support technique and straight needle. Results: The average time of the bypass procedure by the novel considerations (fingertip support and straight needle) was significantly less than the average time by traditional microsurgical support. Conclusion: This in vitro/in vivo animal study provides evidence of the reduction of the suturing time, and thus the exclusion time, by using the fingertip support technique with a straight needle in the bypass procedure.
