Strategies needed to address radiation exposure risks during venous procedures, Venous News, 

 Research presented at the European Society for Vascular Surgery’s annual meeting (ESVS; 25–28 September, Valencia, Spain) has shone a light on the potentially high cumulative radiation exposure associated with certain venous procedures. Addressing the issue, Stephen Black (Guy’s and St Thomas’ Hospital, London, UK) called for further studies to identify strategies that can reduce radiation exposure, and highlighted the need for increased awareness among interventionalists.

Black indicated that there has been an increase in treatment options for deep vein thrombosis (DVT) in particular and for chronic venous patients over the last few years. While the advances are exciting, it is easy to forget that they come with potentially harmful side effects. Black compared modern venous procedures with endovascular aneurysm repair (EVAR), drawing particular attention to the young age at which venous patients typically require treatment, corresponding with a much longer lifetime of follow-up and potential reintervention procedures.

“It is important to highlight the potential for harm in this patient group who are an average age of 30–40 years, as opposed to the older patients who typically undergo EVAR, for example. The EVAR 1 trial reported an increased incidence of malignancy in patients treated endovascularly after 15 years follow-up. Patients who need thrombolysis or inferior vena cava (IVC) reconstruction are often younger than those with arterial problems and may also require long-term surveillance and secondary interventions, exposing them to further radiation,” Black pointed out.

To investigate the radiation exposure associated with venous procedures, Black and colleagues conducted a retrospective cohort study of patients with symptomatic ilio-femoral deep vein thrombosis and chronic IVC reconstruction, followed for a minimum of one year in order to capture reintervention data. Estimated radiation exposure from the related preoperative, index and postoperative interventions were measured in dose-area product and fluoroscopy time. ………

He concluded, adding that more needs to be done to raise awareness about the importance of reducing radiation dose wherever possible, and maintained that more strategies, such as the use of IVUS, need to be identified and put into practice.
