Abstract：
External compression of a vein is a relatively rare but important cause of unilateral leg edema. Here, we present a case of unilateral right leg edema caused by external compression of the right iliac vein due to a markedly distended urinary bladder, secondary to a neurogenic bladder. The patient initially had bilateral leg edema associated with chronic heart failure. However, the right-leg edema worsened and remained painful for several days. Lower extremity ultrasonography and computed tomography revealed an enlarged bladder. Based on these findings, venous angiography and intravascular ultrasound were performed. External compression is a significant cause of leg edema. It is important to consider the possibility of intra-abdominal/pelvic processes that may lead to external compression of the venous system in patients with unilateral and even bilateral lower extremity swelling.
摘要：
静脉的外部压迫是单侧腿部水肿的相对罕见但重要的原因。这里,我们介绍了一例由于膀胱明显扩张引起的右髂静脉外部压迫引起的单侧右腿水肿，继发于神经源性膀胱。患者最初患有与慢性心力衰竭相关的双侧腿部水肿。然而,右腿水肿恶化并持续疼痛数天.下肢超声和计算机断层扫描显示膀胱扩大。基于这些发现,进行静脉造影和血管内超声检查.外部压迫是腿部水肿的重要原因。重要的是要考虑腹部/骨盆内过程的可能性，这可能导致单侧甚至双侧下肢肿胀的患者静脉系统的外部压迫。
