Superficial vein thrombosis is characterized by clotting of superficial veins (ie, following direct trauma) with minimal inflammatory components. Superficial thrombophlebitis is a minimally thrombotic process of superficial veins associated with inflammatory changes and/or infection. Treatments generally include analgesics, elastic compression, anti-inflammatory agents, exercise and ambulation, and, in some cases, local or systemic anticoagulants. It is better to avoid bed rest and reduced mobility. Topical analgesia with nonsteroidal, anti-inflammatory creams applied locally to the superficial vein thrombosis/superficial thrombophlebitis area controls symptoms. Hirudoid cream (heparinoid) shortens the duration of signs/symptoms. Locally acting anticoagulants/antithrombotics (Viatromb, Lipohep, spray Na-heparin) have positive effects on pain and on the reduction in thrombus size. Intravenous catheters should be changed every 24 to 48 hours (depending on venous flow and clinical parameters) to prevent superficial vein thrombosis/superficial thrombophlebitis and removed in case of events. Low molecular weight heparin prophylaxis and nitroglycerin patches distal to peripheral lines may reduce the incidence of superficial vein thrombosis/superficial thrombophlebitis in patients with vein catheters. In case of superficial vein thrombosis/superficial thrombophlebitis, vein lines should be removed. In neoplastic diseases and hematological disorders, anticoagulants may be necessary. Exercise reduces pain and the possibility of deep vein thrombosis. Only in cases in which pain is very severe is bed rest necessary. Deep vein thrombosis prophylaxis should be established in patients with reduced mobility. Antibiotics usually do not have a place in superficial vein thrombosis/superficial thrombophlebitis unless there are documented infections. Prevention of superficial vein thrombosis should be considered on the basis of patient's history and clinical evaluation.

Effective treatment of peripheral vascular disorders is important not only for resolution of local symptoms but also for preventing the development of systemic conditions such as deep vein thrombosis. Topical heparins are widely used in Europe for the prevention and treatment of local symptoms associated with peripheral vascular disorders. This comprehensive review of the literature evaluated the efficacy and safety of topically applied heparins for the treatment of vascular disorders. A total of 1055 patients participated in a total of 20 studies that compared topical heparin formulations with placebo, no treatment, subcutaneous heparin or with each other in the treatment of superficial thrombophlebitis or venous insufficiency. Heparin gel 1000 IU/g (Lioton) 1000 gel, Menaven) 1000 gel) was more effective than placebo in reducing the signs and symptoms of superficial thrombophlebitis. Liposomal heparin gel 2400 IU/g (LipoHep Forte) was as effective as subcutaneous low-molecular-weight heparin at relieving local symptoms of superficial venous thrombosis. In head-to-head studies comparing different topical heparin formulations, all preparations appeared effective but heparin gel 1000 IU/g was superior to a heparinoid mucopolysaccharide cream (Hirudoid) in patients with vascular disorders in terms of resolving spontaneous pain, induced pain, oedema and heaviness in the limb. Another study demonstrated the superiority of heparin gel 1000 IU/g compared with a gel formulation containing heparin 100 IU/g, aescinate and essential phospholipids (Essaven), for symptom resolution. All treatments were generally well tolerated, with a relatively low incidence of local skin events. In summary, topical heparin preparations may be useful for relieving the signs and symptoms of vascular disorders while improving microcirculation. There is some evidence to suggest that heparin gel 1000 IU/g may be more effective than other topical preparations in treating these conditions, possibly because of the relatively high heparin levels in this formulation. This remains to be tested in well controlled, adequately powered clinical trials.
