Abstract

Introduction: Peripheral nerve damage can lead to a loss of nerve continuity for a long time and cause a gap between the nerve endings. With scientific evidence, using vascularized nerve graft (VNG) for long and large-diameter peripheral nerve grafts is one of the optimal indications. This paper aims to present the study's initial results using VNG with peripheral nerve defect at Viet Duc Hospital. Subjects and methods: A cross-sectional descriptive study, longitudinal follow-up of patients with peripheral nerve injury in the extremities with nerve grafts > 10 cm surgically VNG by microsurgery technique from 2020 to 2022 at Viet Duc Friendship Hospital. Evaluation of results based on recovery time, muscle strength, and neurological sequelae. Results: 9 patients with microsurgery grafted saphenous nerve segment with feeding vessel. The male/female ratio is 8/1, and the mean age is 32.8. 08 patients were transversed with phrenic nerve with the musculocutaneous nerve in patients with brachial plexus injury and 01 with sciatic nerve injury. A VNG average length is 17.6cm, average recovery time is 4.75 months. Reach M3, M4: 7/9 patients. Conclusions: VNG is one of the good choices for longitudinal peripheral nerve defects or large diameter of the injured nerve, scarred recipient bed.
