Venography using the combination of contrast material given intravenously in a vein in the arm and computed tomography scans allow the accurate diagnosis of deep vein thrombosis of the lower extremities and pelvis. The advantages of this method included actual visualization of the clot in the lumen of the vein, a more precise evaluation of the upper part of the thigh and pelvic area and the demonstration of adjacent abnormalities, which may contribute to the development of the thrombus. The opposite extremity is visualized at the same time for comparison of the venous systems and the associated muscle and limb swelling of the thrombosed side. There is less pain and risk of serious skin extravasation with contrast material given intravenously in the arm compared with the standard method for venogram using a foot vein. Repeat tests can be easily performed for follow-up studies after thrombolytic or anticoagulant therapy.
通过将造影剂经手臂静脉静脉内注射与计算机断层扫描相结合进行静脉造影，可准确诊断下肢和骨盆的深静脉血栓形成。该方法的优点包括实际观察到静脉腔内的血栓、更精确地评估大腿上部和骨盆区域以及显示可能导致血栓形成的相邻异常情况。同时对另一侧肢体进行成像，以便比较静脉系统以及血栓形成侧相关的肌肉和肢体肿胀情况。与使用足部静脉进行静脉造影的标准方法相比，经手臂静脉注射造影剂时疼痛较轻，且严重皮肤外渗的风险较低。在溶栓或抗凝治疗后，可轻松进行重复检查以进行随访研究。
