Equivalence in Color-coded Duplex Sonography Parameters before Complex Microsurgery.

ABSTRACT

Background: Color-coded duplex sonography (CCDS) is a widely proposed noninvasive diagnostic tool in microsurgery. CCDS has been applied to lower extremity salvage cases to define appropriate blood flow velocity criteria for achieving arterial success in diabetic foot and complex microsurgery cases. This study aimed to compare the success ratio of free flaps when using CCDS versus cases where CCDS was not used. Methods: We included complex microsurgery cases from 2019 to 2021. These cases were subsequently categorized into two groups group A consisted of cases where CCDS parameters were applied, whereas group B comprised cases where CCDS was not performed at all. Results: The study encompassed 14 cases (11 men and three women). The age range varied from 23 to 62 years, with an average age of 42. Using CCDS analysis and planning demonstrated improved outcomes in comparison with cases where CCDS was not performed, albeit without statistical significance (P = 0.064). Conclusions: The application of CCDS proves to be beneficial in the realm of microsurgery. Although not achieving statistical significance, our data imply that CCDS utilization holds promise for enhancing microsurgical procedures.
