Abstract: Objective: To summarize the therapeutic effect of free deep inferior epigastric perforator (DIEP) flap and anterolateral thigh perforator (ALTP) flap in repairing skin and soft tissue defects in chest wall tumor resection.Methods: One old male patient with malignant fibrous histiocytoma of chest wall in China-Japan Union Hospital received operation,and the tumor was extendedly resected.The remaining chest wall defects were 10 cm×10 cm and 18 cm×14 cm,respectively.Free DIEP and ALTP flaps were used to repair the defects,and vascular pedicle was anastomosed with internal mammary artery and thoracic lateral artery,respectively.Results: After operation,the donor area was sutured directly,and two flaps survived with good appearance. The skin of ALTP flap was flatter than that of DIEP flap,and the texture and color of skin were close to those around chest wall.Conclusion: Free DIEP and ALTP flaps are ideal choice for repairing skin and soft tissue defects after resection in the male patient with chest wall tumor.
