Abstract
Introduction:
Hallux surgery is the most commonly performed elective surgery in the foot and ankle. As with all surgery, there are many potential complications quoted in the literature. Venous thromboembolism (deep vein thrombosis and pulmonary embolism) incidence and prophylaxis, however, is not adequately addressed and remains controversial.
Material and Method:
This prospective study includes one hundred patients who underwent hallux surgery. Risk factors implicated to increase the risk of developing venous thromboembolic disease as well as anaesthetic time, thigh tourniquet time and regional anaesthetic blocks were documented. Compressive ultrasonography was performed in all the patients postoperatively to assess for deep vein thrombosis.
Results:
There was one incident of calf deep vein thrombosis (DVT). No patient developed a pulmonary embolus. The one patient who developed a DVT was not at any higher risk than the average patient in the study.
Conclusion:
As a result of the low incidence of venous thromboembolic disease in this study, the authors do not recommend the routine use of chemical venous thrombo-prophylaxis in patients undergoing hallux surgery. The decision to give postoperative anticoagulation remains the surgeon's responsibility. The duration of prophylaxis will depend on when the patient is fully mobile.
