Venous ultrasound imaging was compared with ascending contrast venography for the diagnosis of suspected deep vein thrombosis (DVT) in the femoral, popliteal and calf vein segments of 44 limbs in 44 patients. One femoral and one calf vein segment could not be imaged (1.5% of the segments examined), but during the same period venography failed in six patients because of an inability to cannulate a swollen limb. Ultrasound imaging compared with venography as a means of diagnosing DVT showed an overall sensitivity of 95% and a specificity of 92%. The sensitivity and specificity of ultrasound imaging for the diagnosis of both femoral and popliteal vein thromboses were 100% and 97%, respectively, and for calf vein thrombosis were 85% and 83%, respectively. This study supports the recommendation that ultrasound imaging is now the investigation of choice for the diagnosis of DVT provided that the scan is performed by an experienced vascular technologist. Ultrasound imaging may also define other pathological conditions presenting in the differential diagnosis of DVT, such as superficial thrombophlebitis and Baker's cyst.
对44例患者44条肢体的股静脉、腘静脉和小腿静脉段疑似深静脉血栓形成(DVT)的诊断,将静脉超声成像与上行性静脉造影进行了比较。有1条股静脉段和1条小腿静脉段无法成像(占检查段数的1.5%),但在同一时期,有6例患者因无法对肿胀肢体进行插管而静脉造影失败。超声成像与静脉造影作为诊断DVT的手段相比,总体敏感性为95%,特异性为92%。超声成像诊断股静脉和腘静脉血栓形成的敏感性和特异性分别为100%和97%,诊断小腿静脉血栓形成的敏感性和特异性分别为85%和83%。本研究支持以下建议:只要由经验丰富的血管技术人员进行扫描,超声成像现在是诊断DVT的首选检查方法。超声成像还可以明确DVT鉴别诊断中出现的其他病理情况,如浅静脉血栓形成和贝克囊肿。
