Changes of haemostasis in patients undergoing laser intervention of varices

Endovenous laser ablation (EVLA) is considered to be one of the modern, minimally invasive techniques for surgical management of leg varices. The thermal effect of EVLA can induce endothelium damage and intraluminal thrombus formation in varicose veins. In the case of extension from the superficial to the deep venous system this can bear a risk of pulmonary embolism for the patient. The authors present own research results of the haemostatic changes and endothelium activation in patients undergoing EVLA with the aim of laboratory estimation of the postinterventional thrombogenic risk.

Keywords: endovenous laser ablation, vena saphena magna, haemostasis, endothelium activation and damage.
