摘要
The Radial Forearm Free Flap (RFFF) is one of the most widely used microsurgical flaps for intraoral reconstruction. Although the Clinical Allen Test (CAT) is the most widely used preoperative diagnostic method with which to study the distal patency of the hand prior to the use of RFFF, several authors have reported potentially preventable serious vascular complications. This study included 87 consecutive patients with cancer of the oral cavity and RFFF as the flap of choice who were treated between 2010 and 2020, and compares the results of the Clinical Allen Test (CAT), the Doppler Allen Test (DAT) and the Surgical Allen Test (SAT). The preoperative vascular study found vascular abnormalities severe enough for the surgical team to change the preoperative flap of choice in 39% of patients. The Kappa index showed a weak concordance between the CAT and DAT. The study reflected a total concordance in the preoperative results of the Doppler study and the intraoperative results of the SAT. Due to its excellent agreement with SAT, the DAT would be the preoperative test of choice in patients who are candidates for RFFF. This study of vascular mapping tests with Doppler is intended to inform therapeutic decisions and present methods to gain information that cannot be obtained by physical examination alone.
