title: [Complications of superficial thrombophlebitis].
abstract: Phlebitis and varicophlebitis are regarded as harmless diseases easily treated by compression and local measures such as incisions and applications. However, recent experience has revealed that they are often complicated by growth of the superficial thrombus into the deep veins, by noncontiguous calf thrombosis, and by usually asymptomatic pulmonary embolism. We prospectively examined 25 consecutive patients using duplex scanning (21x) and/or ascending venography (15x). The phlebitic process involved a varicose greater saphenous vein or a branch thereof (19x), the lesser saphenous vein (3x) or a nonvaricose superficial vein (3x). In 11 cases (44%) we found direct extension to involve the deep vein system and/or noncontiguous isolated calf or popliteal vein thrombosis. The presence of risk factors for deep vein thrombosis and a painful calf muscle were good clinical indicators of such complications. Patients with complications were anticoagulated on an outpatient basis. The course was uneventful in most cases. Our study confirms the notion that superficial thrombophlebitis is often part of a more extended thromboembolic process. This implies diagnostic and therapeutic consequences, although the prognostic significance of such complications is not clear at the moment.
