Repair of circular scar in the forearm by expanded double-pedicle Ω-shaped flap at the rear flank of bottom-waist

Objective To discuss the method for repairing the circular scar in the forearm.Methods Large expander (400-600 ml) were implanted subcutaneously at the rear flank of bottom-waist in the way of overlapping or continued expansion. After expansion was completed, the horizontal opened Ω-shaped flap was formed by advancement of expanded skin with the two pedicles at the two sides. Then the forearm was tunneled under flap with the wound covered by flap. The pedicles were cut off at the third stage. Results From April 1998 to June 2009, 8 cases were treated with no flap necrosis. The patients were followed up for1 to 3 years with good flap color and thickness. Flap sensory was partially recovered.Linear atrophic scar was left in the donor sites. Conclusions It is feasible to repair forearm circular scar by expanded double-pedicle Ω-shaped flap at the rear flank of bottom-waist.

Results All the flaps survived completely. The follow-up period ranged from 4 to 19 months. The functional and cosmetic results were satisfactory. The two-point discrimination was 7 ～ 9 mm. The TAM functional examination showed excellent in 59 fingers, good in 11 fingers and common in 2 fingers. Conclusions The technique with island flap is simple and reliable for the defects at the end of fingers.     

腓动脉穿支腓肠神经营养血管游离皮瓣修复手足软组织缺损

Objective To report the operative techniques and clinical results of the free psroneal artery perforator sural neurecutanecus flaps. Methods Free sural neurocutaneous flap with a single unit of perforating veins and artery arising from the peroneal artery was designed to repair skin defects of hand or from the ankle to distal end of the foot. After the flap was transposed to the defect, the perforating artery was anastomozed with a branch of a nearby artery, and the small saphenoas vein was anastomosed with the cephalic vein or the great sapheneous vein to establish the flap's circulation. An alternative way was to anastomose the perforating vessels only. The sural nerve was anastomosed to innervate the flap. Results From Jan 2005 to Dec 2007, 12 cases were treated with the flaps with no flap necrosis. The size of the flaps ranged from 12 crux7 cm to 18 cm× 11 cm. The follow-up period was 7 to 27 months. Both the cosmetic and functional results were satisfactory. Two point discrimination was 7 ～ 12 mm. Conclusions The flap has all the advantages of the h'ee flap, the perforator flap and the neurocutaneous flap. It is easily performed with reliable blood supply. It's a good choice for repairing the skin defects of hands and feet.     

大鼠穿支蒂皮瓣的实验研究

目的建立穿支血管蒂皮瓣的动物实验模型，探讨蒂部穿支血管对皮瓣血供的影响。方法选择30只雄雌不限SD大鼠，分成1个实验组和2个对照组，每组10只，实验组为穿支血管蒂皮瓣组，对照1组为皮下蒂皮瓣组，对照2组为随意皮肤蒂皮瓣组，实验组进行血管造影及组织学检查。结果大鼠腹部皮肤穿支血管起源于腹壁上动脉深支，于腹直肌鞘两侧穿出，共8～10支，穿支垂直间距0．4-1．0cm，以左上第2穿支外径粗大，一条肌皮穿支血管可供养大鼠腹部皮肤81．5％。结论穿支血管蒂皮瓣血供来源于穿支血管，切取穿支血管蒂皮瓣面积比随意皮肤蒂皮瓣面积大，并可提供多种皮瓣设计的选择。     

交通伤所致下肢严重皮肤撕脱伤的治疗

目的探讨交通伤所致下肢严重皮肤撕脱伤的手术治疗方法。方法对2000年12月～2005年6月因交通伤所致的下肢严重皮肤撕脱伤68例患者的治疗进行回顾性分析。治疗方法采用彻底清创后行骨折固定、血管神经修复，用四种处理方法行创面皮肤覆盖。原位缝合8例（外院处理后转入患者）；急诊植皮或皮瓣移植修复38例，其中皮瓣修复26例，返削植皮12例；延迟一期修复15例，即急诊清创后观察3～7d，再进行第二次清创，采用植皮或皮瓣修复创面；二期处理7例中有3例采用游离股前外侧皮瓣移植，2例采用肌皮瓣转位并植皮，2例返削植皮，对因一期处理不当致皮肤坏死或形成皮下囊肿患者采用再次返削植皮。结果原位缝合中1例大部分皮肤成活，7例大面积皮肤坏死。急诊皮瓣完全成活26例，1例边缘部分坏死，其中皮瓣结合皮片移植9例均完全成活，急诊返削植皮12例中10例一期成活，有2例皮片部分坏死。延迟一期修复植皮除1例部分失活，其余皮瓣完全成活。二期处理中皮瓣及植皮均成活。本组患者随访6个月～5年（平均18个月），皮肤创面均完全覆盖，肢体功能恢复：优38例，良23例，差7例，优良率为89．7％。结论准确判断皮肤撕脱伤所累及组织的伤情、安排周密的术前计划、合理选用创面修复方法是确保皮肤撕脱伤肢体功能获得最大程度恢复的关键。

目的探讨双血管蒂髂骨皮瓣移植修复小腿骨及其周围软组织缺损的方法及临床效果。方法2001年5月至2006年3月，应用同时携带旋髂深及旋髂浅双血管蒂的髂骨皮瓣移植治疗23例胫骨骨软组织缺损，切取髂骨块大小4cm×3．5cm～9cm×3．5cm，皮瓣面积最小5cm×8cm，最大12cm×23cm。结果23例骨皮瓣全部存活，6周可见移植髂骨与受区胫骨断端间有少量骨痂形成，平均骨性愈合时间6个月。全部病例术后随访6个月～3年，行走负重良好，外形满意。结论此术式是治疗胫骨骨软组织缺损的一种良好方法，双血管蒂为骨皮瓣尤其是皮瓣的存活提供了可靠保障。     

皮神经营养血管逆行岛状皮瓣修复肢体远端组织缺损

目的分析皮神经营养血管逆行岛状皮瓣修复肢体远端组织缺损的适用性。方法应用皮神经营养血管逆行岛状皮瓣修复30例患者肢体远端组织缺损，其中前臂外侧皮神经营养血管带蒂移植5例，腓肠神经营养血管带蒂移植11例，隐神经营养血管带蒂移植14例。所有被修复创面均有不同程度的血管、神经、肌腱或（和）骨质外露。结果1例患儿术后因蒂部受压致皮瓣远端部分坏死，经换药治愈；1例患者因术后感染，皮瓣周边成活不良，经肉芽植皮术后治愈；其余28例患者所植皮瓣全部成活，血运良好，修复部位外观及功能恢复较为满意。结论皮神经营养血管逆行岛状皮瓣解剖结构恒定，血供可靠，手术操作简单，不损伤主要血管及肌肉组织，适用于肢体远端组织缺损的修复。
