Lower extremity venous thrombosis (DVT) is the most common vascular manifestation of Behçet's syndrome (BS). Currently, Doppler ultrasonography (USG) is the most commonly preferred imaging modality in the diagnosis and follow-up of patients with acute and chronic DVT. Magnetic resonance (MR) venography, a quick and a non-invasive imaging modality, is successfully used to detect DVT in various settings. We had been unaware of studies with MR venography in BS. The aim of this study is to compare the diagnostic value of true fast imaging with steady-state precession magnetic resonance (True-FISP MR) venography and Doppler USG in the assessment of chronic DVT among patients with BS. 28 BS patients with chronic lower extremity DVT were studied. Common femoral (CFV) and femoral vein (FV) on both right and left sides were examined for the presence of thrombosis, recanalisation, collaterals and reflux. There are findings of chronic DVT in all Doppler USG images of 28 patients (45 of 56 FV and 35 of 56 CFV), while MR venography detects chronic thrombotic changes in 26/28 (93%) patients (43 of 52 FV and 28 of 52 CFV). Collateral veins are detected in 19 patients (19/28) with MR venography, whereas they are present in only 7 (7/28) with USG (P = 0.003). Furthermore, patients with severe post-thrombotic syndrome are more likely to have collateral formation on the MR compared to those without (12/14 vs 7/14; P = 0.043). Among patients with BS, MR venography might be an alternative or additional method to detect chronic thrombosis in the lower extremities.
下肢静脉血栓形成（DVT）是 Behçet 综合征（BS）最常见的血管表现。目前，多普勒超声（USG）是诊断和随访急性和慢性 DVT 患者最常用的影像学检查方法。磁共振（MR）静脉造影术是一种快速、非侵入性的成像方式，可成功用于检测各种情况下的 DVT。我们之前不知道有关于 BS 患者使用 MR 静脉造影术的研究。本研究旨在比较真实稳态进动快速成像（True-FISP MR）静脉造影术和多普勒 USG 在评估 BS 患者慢性 DVT 中的诊断价值。 研究了 28 例慢性下肢 DVT 的 BS 患者。对双侧股总静脉（CFV）和股静脉（FV）进行检查，以确定是否存在血栓、再通、侧支循环和反流。在 28 例患者的所有多普勒 USG 图像中均发现慢性 DVT（45/56 FV 和 35/56 CFV），而 MR 静脉造影术在 26/28 例（93%）患者（43/52 FV 和 28/52 CFV）中检测到慢性血栓形成变化。MR 静脉造影术在 19 例（19/28）患者中检测到侧支静脉，而在仅 7 例（7/28）患者中 USG 检测到侧支静脉（P=0.003）。此外，与无侧支静脉形成的患者相比，有严重血栓后综合征的患者更有可能在 MR 上形成侧支静脉（12/14 比 7/14；P=0.043）。在 BS 患者中，MR 静脉造影术可能是一种替代或补充方法，用于检测下肢慢性血栓形成。
