Background: Vacuum-Assisted Closure (VAC) is a technique applied to various difficult cases for the treatment of acute and chronic injuries. Based on this technique, open-cell foam is applied to a suitable wound by adding a cover of adhesive dressing and then applying sub-atmospheric pressure to that wound orderly.
Aim: The main goal of this work is to alleviate the need for free flap transfer through the exemplary use of vacuum-assisted closure.
Patients and Methods: This study was carried out at Azadi teaching hospital during the period from March 2014 to August 2018. The sample consisted of 35 patients where their ages ranged between (10-58) years. The VAC technique was applied to the chronic and acute wounds to which skin graft is not applicable.
Results: A total of 35 wound sites were managed with the VAC technique. The wounds were converted from an unacceptable wound to one that can hold skin graft orderly within (10-15) days.
Conclusion: The VAC opposes the wound surface, accelerates granulation tissue in a way that can accept split skin graft.
Acute wound; Chronic wound; VAC
The VAC is a comparatively innovative technique applied to various difficult cases for the treatment of acute and chronic injuries . This technique involves applying an open cell foam to a suitable wound by adding a cover of adhesive dressing and then applying subatmospheric pressure to that wound orderly . Previous studies have reported encouraging outcomes regarding healing rates . In 1997, the VAC technique was first investigated by Morykwas MJ, et al. (1997)  WHO suggested that the healing of wounds might be improved through applying this technique. Early works argued that the negative pressure technique increases blood flow, as demonstrated by hyperemia .
Delayed healing of a wound, especially in complex injuries and in aged people with comorbidities, is a key concern. It causes morbidity and lengthy treatment. Also, it may require major reconstructive surgery. This, in turn, could impose a considerable social, technical, and financial burden [4,5]. VAC is an alternative method to the management of wounds by employing negative pressure for preparing the wound for spontaneous recovery or by minor reconstructive decisions .
