Observation of the Absence of Ulnar Artery in a Patient Planned to Free Dorsoulnar Artery Perforator Flap for Finger Defect: Is Preoperative Doppler evaluation of Perforator Alone Sufficient?

Abstract Background Volar finger defects where critical structures exposed are always challenging for plastic surgeons. In these types of defects, local flaps, cross abdominal and free flaps used. Free dorsoulnar artery perforator (DUAP) superficial palmar branch radial (SPBRA) also this case, we present a patient who was scheduled to receive DUAP flap address defect on the second right hand; however, repaired with SPBRA because intraoperative absence ulnar observed. Materials Methods A 34-year-old male admitted wound that tendon neurovascular bundle volar side hand. planned patient. detected during preoperative Doppler ultrasound examination. While dissecting perforator, noted an proximal vessel. The elevated from same extremity were closed. Results Postoperative computer tomography showed distal antecubital region. No complications seen in donor recipient areas. Long-term motor movements natural, patient's quality life good. Conclusion Determining site using alone may not be sufficient evaluation patients flaps. Performing Allen test advanced imaging methods can prevent surgeons encountering bad surprise.
