Vacuum-Assisted Closure: An Effective Technique to Manage Wound Complications After Metastatic Spine Tumour Surgery (MSTS)—A Case Report

ABSTRACT

The management of wound complications following metastatic spine tumor surgery (MSTS) remains a formidable task. Plastic coverage procedures after MSTS are challenging due to unhealthy donor sites following previous radiotherapy and prolonged nonambulation. Negative pressure wound therapy (NPWT) is usually not recommended after MSTS due to fear of tumor seeding and excessive blood loss. However, in certain patients post-MSTS, who may be considered as receiving palliative treatment, NPWT can be effective in managing wound complications. We describe our initial experience with the use of NPWT in a 57-year-old lady diagnosed with multiple lumbar and cervicothoracic vertebral metastases secondary to non-small cell lung carcinoma. She underwent 2 cycles of preoperative radiotherapy followed by decompression and posterior instrumentation of lumbosacral and cervicothoracic regions succeeded by another cycle of radiotherapy. The patient developed wound dehiscence and poly-microbial surgical site infection that was not responsive to regular debridements and antibiotics. Hence, we applied NPWT as an alternative treatment to plastic surgical procedures. The patient clinically improved with a reduced quantity of wound discharge, increased granulation tissue, and a downward trend in the inflammatory markers. Subsequently, wound was secondarily closed after 14 days. The patient was discharged after a total hospital stay of 41 days. The intravenous antibiotics (piperacillin/tazobactam) were changed to oral (ciprofloxacin) after 6 weeks and continued for 4 months. The patient survived for 3 years without any wound complications. Our case report suggests that NPWT can be a potential treatment option for managing wound complications following MSTS.
