Objective:
To analyze prevalence of venous thromboembolism (VTE) after ultrasound guided foam sclerotherapy.
Method:
Clinical retrospective study with patients treated from 2004 to 2014. Charts with incomplete data and follow-up less than 60 days were excluded. Polidocanol foam (Tessari method) was used. The primary outcome was the prevalence of VTE and the secondary were possible risk factors. Chi-square test and Marascuillo prodecure were applied at a significance level of 5%.
Results:
2,616 patients were included with 4,712 lower limbs treated. The mean age was 50.7±0.86, in majority female, 83.7%. VTE occurred in 0.49% (pulmonary embolism 0,3%) in a mean time of 44.0±42.2 days. Male gender, personal or family history of phlebitis or DVT and high caliber varicose veins were significantly associated to VTE.
Conclusion:
incidence of VTE is low, male gender, personal or family history of VTE and caliber of varicose veins greater than 7 mm increased the risk.
