The purpose of this study was, first, to determine the incidence of underlying occult deep venous thrombosis (DVT) in patients with superficial thrombophlebitis and, second, to see if any risk factors are helpful in identifying these patients.
Forty-four consecutive patients with a clinical and duplex ultrasound-confirmed diagnosis of superficial thrombophlebitis were assessed for DVT. All patients had a duplex ultrasound study of the deep venous system. Standard thrombosis risk factors were assessed for each patient.
Ten patients (23%) had DVT. All cases were clinically occult. One patient had propagated thrombus in the common femoral vein. Three patients had popliteal vein thrombi. The remaining patients had calf vein thrombus only. Four of these were not in continuity with the superficial thrombus. The site of the superficial thrombophlebitis was not predictive of DVT. None of the known venous thrombotic risk factors were helpful in identifying patients at risk for DVT.
Noninvasive deep venous studies are recommended in all patients with lower limb superficial thrombophlebitis because of the high incidence of occult DVT. Patients with DVT can then be treated appropriately.
本研究的目的，其一，是确定浅表血栓性静脉炎患者潜在隐匿性深静脉血栓形成（DVT）的发生率；其二，是观察是否有任何危险因素有助于识别这些患者。
对44例经临床及双功超声确诊为浅表血栓性静脉炎的连续患者进行DVT评估。所有患者均接受了深静脉系统的双功超声检查。对每位患者评估标准血栓形成危险因素。
10例患者（23%）发生DVT。所有病例临床均隐匿。1例患者股总静脉有血栓扩展。3例患者腘静脉有血栓。其余患者仅有小腿静脉血栓。其中4例与浅表血栓不连续。浅表血栓性静脉炎的部位不能预测DVT。已知的静脉血栓形成危险因素均无助于识别有DVT风险的患者。
由于隐匿性DVT发生率高，建议对所有下肢浅表血栓性静脉炎患者进行无创性深静脉检查。然后可对DVT患者进行适当治疗。
