锁骨下血管合并臂丛损伤的处理

目的 探讨锁骨下动脉合并臂丛神经损伤的诊断和处理。方法 5例锁骨下动脉损伤合并臂丛损伤，其中锁骨下动脉第一段损伤1例，第三段损伤4例；2例合并动脉瘤，1例动脉瘤加动静脉瘘．2例血管纤维化自行闭塞。根据锁骨下动脉损伤性质，分别采用静脉移植、直接缝合、血管结扎处理，损伤臂丛神经采取直接缝合、神经松解。结果 3例开放性损伤患者早期手术修复动脉和神经，术后伤肢无疼痛，神经功能有不同程度恢复；2例闭合钝器伤晚期患者，1例行血管、神经松解术，仅疼痛减轻，1例血管臂丛神经广泛粘连，神经松解术后无任何恢复。结论 除原发性损伤外，进行性增大的血肿或假性动脉瘤压迫可加重臂丛神经损害．如能早期处理血肿或动脉瘤，解除压迫，可减轻神经损害，有利于臂丛神经功能恢复。

Clinical significance of leukocyte infiltrative response in deep wound of patients with major burns

OBJECTIVE: To investigate the time course of infiltrated leukocytes and the subpopulations of infiltrated lymphocytes in deep wounds, and their relationship with injury severity in seriously burned patients. METHODS: Six patients with major burns were enrolled in the study. Specimens were taken from deep partial-thickness burn wounds of all patients at 3 days, 1 week, 2 weeks and 3 weeks after burn. The appearance time and cellular components of infiltrated leukocyte zone in the burn wound were evaluated by histological and immunohistochemistry examination with lymphocyte monoclonal antibodies. RESULTS: The infiltrated leukocyte zone of burn wound formed 1-2 weeks after burn. The more severe the degree of injury (including burn area, depth and combined injuries) was, the later the infiltrated leukocyte zone appeared. The infiltrated cells mainly consisted of polymorphonuclear leukocytes (PMN) during the early period after burn while macrophages and lymphocytes appeared later. There were some changes of the T lymphocyte subsets and their activation degree in the burn wound. CONCLUSION: The changes of infiltrated leukocyte zone of wound following burns were closely related to the injury severity, and represented alteration of the anti-infection ability and immune rejection of local wound. These results provide important evidence for appropriate wound treatment and prolonging the survival of skin allograft.

目的 为解决由股深动脉分支供血的股薄肌肌皮瓣因血管蒂在股薄肌中上1／3处，致使向骨盆会阴带蒂转移时距离受限的问题，探索该肌皮瓣由闭孔起始部为旋转点向骨盆会阴区域转移的方法。方法 根据闭孔动脉-旋股内侧动脉-股深动脉分支之间存在良好吻合支，设计以闭孔动脉跨区供血的长型股薄肌肌皮瓣转移的方法。这种方法可以切断股深动脉分支，使股薄肌肌皮瓣能够更松弛地转移至骨盆、外阴、耻骨、联合、腹股沟等区域。结果修复骨盆会阴区的畸形和缺损9例，所有肌皮瓣均全部成活，经术后3个月至3年的随诊，效果均满意。结论 闭孔动脉跨区供血的长型股薄肌肌皮瓣，可以作为常规的肌皮瓣在临床应用。     

Wedge-Shaped Excision and Modified Vertical Mattress Suture Fully Buried in a Multilayered and Tensioned Wound Closure

Background  A successful deep multilayered wound suture should provide a firm tension-relieving closure, good wound-edge eversion, hemostasis, and minimal intradermal extraneous materials. However, this is not always achieved with a single standard technique. The authors describe their modification of a wound closure method that can rapidly and reliably achieve these results. Methods  A wedge-shaped excision was adopted to obtain a trapezoid pattern transect, after which a modified fully buried vertical mattress suture technique was used to close the wound. These techniques were compared with the standard excision and suture techniques used for the same patient at different times after surgery. Results  The wedge-shaped excision can facilitate good wound-edge eversion, and the modified fully buried vertical mattress suture can provide firm tension relief and optimal apposition. Compared with conventional excision and suture techniques, the described techniques brought about a better outcome in terms of hypertrophic scar prevention. Conclusion  The described modified technique seems to be more efficient than conventional procedures used to prevent hypertrophic scar formation.
