One-staged coverage and revascularisation of traumatised fingers by neighboring digital artery flow-through flaps / 中华显微外科杂志

ABSTRACT

Objective To investigate the clinical application of neighboring digital artery flow-through flaps for one-staged skin coverage and revascularisation after severe finger injuries.Methods From May 2008 to July 2010,there were ischemic fingers had severe injuries,aged 19 to 52 years old,which were male in 5 cases,female in 2 cases,with skin and arterier defected.One-staged coverage and revascularisation of traumatised fingers were used with neighboring digital artery flow-through flaps.Functional exercise and physical therapy were done 3 weeks later.All cases had more than 12 months' fellowed-up periods.The sensibility testing,Questionnaire of the flap aesthetic satisfactory and TAM evaluations were all performed in all patients.All the results were measured and evaluated.Results All flaps survived completely and digit blood circulations were good in 7 patients.The flaps had good appearance and aesthetic satisfactory (100％).At 12 months after operations,the pain and touch perception reinnervated until 6 months and two-point discrimination testing were 6.1 to 9.6 mm,mean was (7.1 ± 1.3) mm,and the flap sensibility assessment were S3 * and TAM evaluation ratio were 0.81 ±0.16.Conclution Neighboring digital artery flap ideally suited as a thin and pliable flow-through flap in digital replantation/revascularization.It is helpful for salvage of the ischemic fingers after injury with skin and arteries defects.
