Abstract
Objective To survey current antithrombotic prophylaxis regimes of foot and ankle surgeons in the UK, and their self-reported rates of deep vein thrombosis (DVT) and pulmonary embolism (PE).
Method A postal questionnaire was sent to 180 members of the British Orthopaedic Foot and Ankle Society requesting regime and types of antithrombotic prophylaxis (if any) used for elective forefoot, elective midfoot, open elective ankle, elective ankle arthroscopy and ankle trauma surgery, and numbers of cases of DVT and PE.
Results Ninety surgeons responded (50%). Surgeons had been practising as consultants with a special interest in foot and ankle surgery for an average of 8.9 years, and performed an average of 24 foot and ankle cases per month. Ten per cent never used antithrombotic prophylaxis in foot and ankle surgery, 64/90 used it routinely for certain cases, and 17/90 used it routinely in all patients. The most common types of prophylaxis were low molecular weight heparin, aspirin and TED stockings. In an approximate overall total of 223,500 foot and ankle cases, the self reported DVT rate was 0.1%. There were 45 reported PEs (0.02%). There was no significant difference in the rate of DVT between those who never, sometimes or always used prophylaxis. Only 5.5% surgeons employed a specific screening protocol to identify high risk patients.
Discussion There is widely varying clinical antithrombotic practice among foot and ankle surgeons in the UK, with no significant difference in reported DVT rates. This has implications for clinical practice and medicolegal issues.
