The characteristics of leukocyte rheology are side-flow towards, adhesive and less deformability. Firstly, leukocytosis can result in the blood flow slower or no-reflow phenomenon in capillaries, then disorderly microcirculation and oxygen deficiency of tissue take place. Secondly,it also disperses three harmful factors: lysosome enzyme, LT and free radical. Thus microcirculation is further damaged, then the blood supply of tissue deteriorates. Leukocytosis can be seen pre-operation or post-operation due to...

The characteristics of leukocyte rheology are side-flow towards, adhesive and less deformability. Firstly, leukocytosis can result in the blood flow slower or no-reflow phenomenon in capillaries, then disorderly microcirculation and oxygen deficiency of tissue take place. Secondly,it also disperses three harmful factors: lysosome enzyme, LT and free radical. Thus microcirculation is further damaged, then the blood supply of tissue deteriorates. Leukocytosis can be seen pre-operation or post-operation due to injuries, burns and operation. The increasing number of leukocytes can make the blood supply of microcirculation decrease. Furthermore,skin flap failure or necrosis. For improving the leukocyte rheology in the microcirculation of skin flap, enhancing the blood supply of skin flap, there are six practical points.

白细胞具有趋边流动,粘附嵌墓及变形能力差等流变学特性,一方面可导致毛细胞血管中血流减慢或血流暂停,出现微循环紊乱,引起组织缺血缺氧;另一方面又释放溶酶体酶类,白三烯类物质及自由基等三种有害物质,造成微循环的进一步损害,组织营养进一步恶化。皮瓣移植前后由于外伤,烧伤及手术创伤等因素均可导致机体白细胞升高,使皮瓣微循环血流量逐渐减少,甚至出现皮瓣危象或皮瓣坏死。本文对上述有关问题进行了阐述,并为改善皮瓣微循环中的白细胞的流变行为,促进皮瓣好转,提出了一些见解。

Purpose:To investigate the pathogensis of failing flaps in oral and maxillofacial surgery and the prevetive measures for flap failure, hased on our clinical data in 1151 patients, with an emphasis on surgical exploration of failing flaps. Methods: The various factors related to flap ischemia - reperfusion injury and the pathogenesis were reviewed. The multiple methods for flap monitoring were evaluated. Surgical exporation of failing flaps was described in detail and the precautions for failing flaps were proposed. Results: A total of 1151 free tissue transfers were performed in our department since 1979. 148 flaps developed vascular crisis, 89 were successfuly sal- vaged, with a success rate of 60.1 %, higher than that reported abroad(40 %) ; Conclusions: Selection of appropriate patients and/or flaps, careful manipulation intraoperatively and minimizing ischemic time as much as possible are still the main factors that ensure Success of free tissue transfers. Further study is needed for topical topical systematic use of drugs to prevent and treat failing fialps.

目的:本文结合临床资料和文献报道,对口腔颌面部游离皮瓣危象的发生机制、防治措施等进行了探讨。方法:总结引起游离皮瓣发生缺血一再灌注损伤的各种因素及机制,评价各种术后监测方法,重点介绍危象皮瓣的手术探查,各种情况的处理,提出防止游离皮瓣发生血管危象的措施。结果:自1979年开展游离组织瓣移植手术至今,我科共累积病例1151例,手术后148例出现血管危象,抢救成活89例,抢救成功率60.1%,高于国外同类报道(40%)。结论:选择合适的病例/皮瓣,术中精心操作,尽量缩短缺血时间,仍是目前确保游离组织移植成功的最重要因素,局部或全身应用药物防治危象皮瓣,仍需进一步研究。

PURPOSE: For the purpose of enhancing the successful transplanting rate of free flaps and reviewing the clinical characters, a retrospective study was undertaken to analyze the causes as well as clinical characters of the failing flap in oral and maxillofacial regions. METHODS: A total of 832 free revascularized flaps were performed in our department from August 1997 to April 2003. The data including the time to occurence, causes, clinical characters and the managements of flap crises were reviewed and then...

PURPOSE: For the purpose of enhancing the successful transplanting rate of free flaps and reviewing the clinical characters, a retrospective study was undertaken to analyze the causes as well as clinical characters of the failing flap in oral and maxillofacial regions. METHODS: A total of 832 free revascularized flaps were performed in our department from August 1997 to April 2003. The data including the time to occurence, causes, clinical characters and the managements of flap crises were reviewed and then analyzed. RESULTS: Forty-four flaps developed vascular crisis (5.29%), most of them were caused by venous occlusion (38/44). Thirty-eight in forty-four flaps crises occurred within 72 hours (86.36%). 32 flaps crises were explored with 21 flaps successfully salvaged; the success rate was as high as 65.63%. CONCLUSIONS: For the highest successful transplanting rate of free flaps, the management of the local factors plays an important role. Most of the failing flaps happened within three days after operation. The surgical exploration should be done as soon as possible, if the crises flap happened within six hours.

目的:回顾分析832例口腔颌面部游离组织瓣移植病例,探讨发生组织瓣危象的原因,提高游离组织瓣移植的成功率。方法:自1997年8月~2003年4月,共制备游离组织瓣832块,对皮瓣危象发生的时间、原因、临床表现、演变过程、应急处理等进行总结和分析。结果:832例组织瓣中,44例出现危象,占5.29%,以静脉栓塞为主占绝大多数(38/44)。发生于术后72h内者38例,占86.36%;其中对32例进行手术探查,21例抢救成功,占65.63%。结论:游离组织瓣移植成功率高,关键在于局部处理得当。术后3d内要密切观察,一旦出现危象,应在6h内进行积极手术探查。
