Abstract:
Background Free tissue transfer using microvascular surgery has become a safe a reliable means to repair soft tissue and/or bony defects of the head and neck. Operative success reaches 98%, however the incidence of significant post-operative complication is also relatively high (32%). One common and often severe complication is haematoma formation at either donor or recipient sites. The incidence of recipient site haematoma is reported at 6%, however the causes and outcomes of haematomas have not been well investigated. A retrospective historical analysis of both donor and recipient site wound haematoma was performed to identify causative factors and the effect on patient outcome. Methodology A five year review was conducted for microvascular free tissue transfer to defects in the head and neck at The Royal Melbourne Hospital, for the period from February 2001 until February 2006. The medical records of these 150 patients were reviewed for donor and recipient site wound haematoma and outcomes. Results Significant factors for the development of post-operative haematomas included lood pressure control during the first post-operative, correlating with the likelihood of developing either a donor or recipient site haematoma (p value < 0.001), drain-tube outputs (both high and low), smoking and the use of pre-operative NSAIDs. Conclusion There are significant reversible factors that contribute to the development of post-operative haematomas in head and neck surgery. Close monitoring of patient blood pressure by theatre and recovery nursing staff, close monitoring of drain outputs, and pre-operative counselling on the use of NSAIDs and smoking may all be useful in the prevention of haematoma formation.Document Type: Research article
