<qa>  What is the primary outcome of the pilot study?As a pilot study, the primary outcome will involve feasibility measures. The investigators aim to measure the proportion of recruitment within each centre, compliance, loss to follow-up, and tolerability of the intervention, defined as the number and severity of per-defined adverse events. The primary outcome of interest for the future full-scale trial is the 30-day incidence rate of VTE following extended 30-day prophylaxis defined as pulmonary emboli or deep venous thromboembolism of the lower limb as detected by CT Computed Tomography pulmonary angiography and full leg Doppler ultrasound, respectively following lung resection for malignancies.
