目的总结巨大纵隔肿瘤的外科治疗方法。 方法回顾性分析我院胸外科2008年10月至2013年10月18例巨大纵隔肿瘤患者的临床资料，其中男10例、女8例，年龄33.5（13～63）岁。肿瘤完整切除12例，大部分切除6例；良性肿瘤11例，恶性肿瘤7例。 结果全组围手术期无死亡病例，术中呼吸循环衰竭2例。术后发生复张性肺水肿2例，损伤喉返神经l例，肌无力危象1例，心律失常10例，胸腔活动性出血再次开胸止血l例，经治疗均恢复良好出院。 结论手术治疗是巨大纵隔肿瘤的主要治疗方法，良性肿瘤患者手术效果佳，恶性者生存时间与组织分化及肿瘤分期有关，手术以缓解症状为主。
Objective To investigate the effectiveness of ipsilateral digital proper artery dorsal branch flap to repair mid-phalanx degloving injury with distal segment finger defect. Methods Between February 2013 and July 2016, 11 cases (11 fingers) of mid-phalanx degloving injury with distal segment finger defect were treated. There were 9 males and 2 females with an average age of 33.6 years (range, 18-59 years). The injury caused by twisting in 8 cases and crushing in 3 cases. The injury located at index finger in 3 cases, middle finger in 6 cases, and ring finger in 2 cases. The skin avulsion was from proximal interphalangeal joint in 1 case, proximal 1/4 of mid-phalanx in 6 cases, and 1/2 of mid-phalanx in 4 cases. The area of wounds ranged from 4.0 cm×1.7 cm to 6.2 cm×2.6 cm. The interval between injury and operation was 2.5-6.0 hours (mean, 4.5 hours). All defects were repaired with the ipsilateral digital proper artery dorsal branch flaps. The size of flaps ranged from 4.4 cm×1.9 cm to 7.0 cm×2.9 cm. Nerve anastomose was carried between digital proper nerve dorsal branch in the flap and digital proper nerve stump in the wound. The donor sites were repaired by skin grafting. Results Tension blisters of the flap and partial necrosis occurred in 1 case, and healed after dressing change. The other flaps and skin grafting survived, and wounds healed by first intention. All patients were followed up 6-18 months (mean, 16 months). The texture and appearance of all the flaps were satisfactory. At 6 months after operation, two-point discrimination of flaps ranged from 7 to 10 mm (mean, 8.5 mm). At last follow-up, according to the functional assessment criteria of upper limbs by the Branch of Hand Surgery of Chinese Medicine Association, the results were excellent in 10 cases and good in 1 case, with the excellent and good rate of 100%. Conclusion The ipsilateral digital proper artery dorsal branch flap is a good method to repair mid-phalanx degloving injury with distal segment finger defect for the advantages of simple operation, less damage in donor site, high survival rate of the flap, and good feeling recovery of the finger.
