Most cases of phlebitis in the legs are caused by the presence of varicose veins or hidden varicose veins. We know that varicose veins are caused by irregular venous flows, vein wall damage and venous reflux, where blood flows back down the vein in the wrong direction, leading to cases of inflammation and vein swelling. By treating these venous issues with varicose vein treatments, the venous reflux can be stopped in its tracks, allowing the patient to prevent further phlebitis or a serious worsening of the condition. By seeking out a detailed venous duplex ultrasound scan with us, we are able to accurately assess the extent of your phlebitis, before proposing a suitable treatment to target the symptoms and prevent further complications. It is essential to request this detailed assessment if you are suffering from phlebitis, so that we can rule out or treat any underlying deep vein thrombosis (DVT) and pulmonary embolism (PE) issues, which can be life-threatening in some cases.
