Compression following treatment of superficial venous incompetence: systematic review

Abstract

Abstract Background International guidelines recommend postprocedural compression when treating symptomatic superficial venous incompetence (SVI). This updated review of RCTs investigated the requirement for postprocedural compression and how it can be applied optimally. Methods The National Institute for Health and Care Excellence’s Healthcare Databases Advanced Search engine was used to identify all English-language RCTs of compression following treatment for SVI. Outcomes of interest included postprocedural pain, venous thromboembolism, health-related quality of life (HRQoL), and anatomical occlusion. Results A total of 18 studies were included comprising some 2584 treated limbs. Compression was compared with no compression in four studies, nine studies compared different durations of compression, and a further five compared different types of compression. A 1–2-week period of compression was associated with a mean reduction of 11 (95 per cent c.i. 8 to 13) points in pain score on a 100-mm visual analogue scale compared with a shorter duration (P < 0.001). This was associated with improved HRQoL and patient satisfaction. Longer durations of compression did not add further benefit. There was low-quality evidence suggesting that 35-mmHg compression with eccentric thigh compression achieved lower pain scores than lower interface pressures. There were no significant differences in venous thromboembolism rates or technical success in any group, including no compression. Conclusion Postprocedural compression of 1–2 weeks after SVI treatment is associated with reduced pain compared with a shorter duration. The optimal interface pressure and type of compression, and the impact on venous thromboembolism risk, remain to be determined.
