EP.WE.791Assessing the use and effectiveness of catheter-directed thrombolysis in a single vascular centre

Abstract

Abstract Aims In the UK, venous thromboembolism remains a leading cause of mortality and morbidity. This audit aimed to assess the use, success and cost of the average patient journey undergoing catheter-directed thrombolysis (CDT) following a diagnosis of a deep vein thrombosis (DVT) within a single vascular centre. Methods A retrospective audit of all procedures (n = 249) between 2010 and 2019 coded as 'angioplasty' were identified; only adults that had CDT for a confirmed iliofemoral DVT were included. Patient anthropological, biochemical and radiological data were collected. Cost of items were confirmed with appropriate hospital departments. Results In ten years, a total of 36 patients (21 female, 15 male, mean age 47 years) started CDT for iliofemoral DVT; one procedure was abandoned due to safety reasons. Almost half of DVTs were provoked. Ultrasound confirmed diagnosis in 92% of patients. CDT was successful in approximately 70% of patients. A quarter of patients developed another DVT following discharge. Average length of stay was 8 days at a cost of £11,235 per patient journey. All patients commenced an anticoagulant regime on discharge. Conclusions This audit supports the use and effectiveness of CDT to treat patients with iliofemoral DVT, however there is a room for improvement regarding long term success given the significant patient and financial costs involved.
