To evaluate the occurrence of deep vein thrombosis (DVT) in patients with superficial vein thrombosis (SVT).
A prospective study in patients with sonographically proven SVT.
Outpatient department of the Department of Dermatology, Medical University of Graz. Patients Forty-six consecutive patients with superficial vein thrombosis were enrolled. Intervention Every patient underwent color-coded duplex sonography of both lower extremities at the beginning of the study.
Important risk factors (eg, history of thromboembolic events, recent immobilization, active malignant disease, and the use of oral contraceptives) were investigated.
In 24% of our patients, a concomitant, mostly asymptomatic DVT was found. In 73% of these patients, the DVT occurred in the affected leg, in 9% in the contralateral leg, and in 18% in both legs. The calf muscle veins were most commonly involved. In all patients with DVT, the SVT was located on the lower leg and the D-dimer findings were positive.
Superficial vein thrombosis is not a life-threatening disease, but the risk of concomitant DVT cannot be ignored. Color-coded duplex sonography should be performed in patients with SVT to rule out DVT.
评估浅静脉血栓形成（SVT）患者深静脉血栓形成（DVT）的发生率。
对超声检查证实为SVT的患者进行前瞻性研究。
格拉茨医科大学皮肤科门诊。患者连续纳入46例浅静脉血栓形成患者。干预在研究开始时，每位患者均接受双下肢彩色编码双功超声检查。
调查重要危险因素（如血栓栓塞事件史、近期制动、活动性恶性疾病和口服避孕药的使用情况）。
在我们的患者中，24%发现合并有DVT，大多无症状。在这些患者中，73%的DVT发生在患侧下肢，9%在对侧下肢，18%双侧下肢均有。小腿肌肉静脉最常受累。所有DVT患者的SVT均位于小腿，且D-二聚体检查结果为阳性。
浅静脉血栓形成并非危及生命的疾病，但合并DVT的风险不可忽视。SVT患者应行彩色编码双功超声检查以排除DVT。
