AI Article Synopsis
- The study investigates the effectiveness of flow-through anterolateral thigh perforator (ALTP) flaps for repairing complex severed limbs with significant tissue and vascular damage.
- Thirteen patients with severe injuries underwent surgery using the ALTP flap technique, with most showing successful limb and flap survival, although some experienced complications like limb shortening and necrosis.
- Overall, the findings suggest that the flow-through ALTP flap technique is beneficial for restoring function in severely injured limbs, despite some challenges faced during the healing process.
Article Abstract
Objective: To explore the clinical application value of flow-through anterolateral thigh perforator (ALTP) flaps in replantation of complex severed limbs.
Methods: Thirteen severe vascular, nerve injury, and skin or soft tissue defects in patients with complex severed limbs from August 2017 to January 2019 were enrolled in this retrospective study. The skin flap has covered the wound by using the flow-through ALTP flap technique. The main vascular defect was repaired by using the descending branch of the lateral circumflex femoral artery, and the blood supply of the transplanted limb was reconstructed. The blood supply of the flap and wound healing observed were observed after the operation. Regular follow-up was performed to observe the survival and functional recovery of the replanted limb.
Results: Eleven cases of replanted limb and perforator flap survived completely. Limb shortening occurred in 3 patients owing to bone defects caused by distal amputation. After the second stage of bone transplantation, the limb length and function of those 3 patients recovered well. One case showed necrosis of the little finger after replantation of the severed palm. One case showed that the crushed forearm was severed completely. The anastomotic vascular inflammatory embolism was caused by infection and necrosis of soft tissue after replantation for 2 weeks, and then the stump wound was covered with a survived skin flap in the second stage.
Conclusion: The flow-through ALTP flap technique has a good therapeutic effect on the functional reconstruction of complex severed limbs with severe skin and vascular injuries.
