Figure 4. Fixation of the LVA incision using four hook-type retractors. Fixation of the surgical site of LVA. The needle hook-type retractors are useful in LVA to fix the surgical site for suturing small vessels. Four needle hook retractors can keep the stable surgical site for fine procedures of dissection and anastomosis under the operating microscope. Because the incision site of LVA is small (usually 1.0-2.5 cm), larger retractors tend to interfere with the fine procedure. LVA: Lymphaticovenular anastomosis.
