Trial design

CTIS Part I — objectives, methods, condition coding

Main objective

Scope: Others

The primary objective is to compare the incidence of partial flap loss requiring surgical intervention within 1 month between patients undergoing intraoperative ICG angiography and those assessed using standard clinical methods.

Secondary objectives 5

  1. Flap loss within one month.
  2. Flap related re-exploration rate in general anaesthesia within one month.
  3. Flap salvage rate within one month.
  4. Postoperative complications (graded according to the Clavien-Dindo classification) within three months.
  5. Association between intraoperative SPY-Q perfusion values and partial flap loss within 30 days, assessed using quantitative perfusion measurements derived from intraoperative indocyanine green fluorescence angiography.
