腓肠内侧动脉穿支蒂皮瓣修复膝和小腿上1/3软组织缺损

目的 报道应用腓肠内侧动脉穿支带蒂皮瓣修复膝和小腿上1/3软组织缺损的临床应用效果. 方法 应用腓肠内侧动脉穿支带蒂皮瓣修复膝和小腿上1/3软组织缺损16例.其中,髌前4例,前外侧2例,前内侧l例;小腿上1/3 9例.供区均选用同侧小腿.结果 手术后经过顺利,1例术后发生表浅感染,经更换敷料逐渐愈合,皮瓣全部成活.随访3.0个月至3.5年,平均1.7年.供区愈合良好,未见明显的供区功能障碍.受区皮瓣质地、厚薄及颜色均较好,功能恢复较好,取得了较满意的效果. 结论 腓肠内侧动脉穿支带蒂皮瓣以腓肠内侧动脉的肌皮穿支为血供,具有血供丰富、血管解剖恒定、血管蒂长以及皮瓣较薄的优点.带蒂移植适宜修复膝和小腿上1/3软组织缺损.

Medial sural artery perforator pedicled flap for the coverage of soft tissue defects around the knee and upper ORe third of lower leg

Objective To summarize clinical application of the medial sural artery perforator pedicled flap for the coverage of soft tissue defects around the knee and upper one third of lower leg.Methods From May 2003 tO January 2007,16 patients(11 men,5 women)with soft tissue defects around the knee and upper one third of lower leg underwent reconstruction with the medial sural artery perforator pedicled flap.Of them,4 eases recipient site were located on the prepatellar region,2 cases were located on the anterolateral pateflar,1 case was located on the anteromedial patellar,and 9 cases upper one third oflowerleg.They ranged in age from 23 to 52 years(mean,36 years).The donor leg was ipsilateral in all cages. Results One ca8e sustained superficial infection postoperative and the gradual wound healed by daily wound dressings.All the flaps had survived completely without major complication with satisfactory clinical results. Follow-up period ranged from 3.0 months to 3.5 years(mean, 1.7 years)postoperatively.There was no remarkable donor site morbidity.All cases had good appearance and function in recipient site.There was no remarkable donor site morbidity. Conclusion The medial sural artery perforator flap is nourished by the musculocutaneous perforater of the medial sural artery.The flaps seem to has highly vascularize,a constant vascular anatomy and a long vascular pedicle.The flap is thin and suitable for the coverage of soft tissue defects around the knee and upper one third of lower leg.
