Lower limb venous anomalies, including duplicated veins, are common and have significant impacts on the outcomes and efficacy of venous surgery. Digital subtraction angiography (DSA) guided venography, serving as the tertiary diagnostic option for venous disorders, offers valuable informations to clinical practitioners.
A retrospective study was conducted on 195 patients with suspected venous disease, evaluating 259 limbs with venography imaging. Two experienced interventional vascularists evaluated the images to determine the incidence and characteristics of variances in the femoral, popliteal, great saphenous, and small saphenous veins. Moreover, blood samples were collected to assess the safety of the venography procedure by monitoring changes in renal function.
Duplication variations were found in the lower limb veins, with the highest prevalence in the femoral vein (11.28%, 22/195), followed by the great saphenous vein (4.1%, 8/195), and the popliteal vein (1.54%, 3/195). No severe contrast agent allergies or postoperative complications were reported. No statistically significant differences were found in creatinine and urea levels pre- and post-operation for patients without duplication variations, those with duplication of the great saphenous, femoral, or popliteal vein ( < .05).
DSA-guided venography is effective in identifying venous variations in lower limb disease. DFV is the most common recurrent vein, while DPV is the least. Adequate preparation ensures safety, high spatial resolution, dynamic imaging, and low tissue interference.
下肢静脉异常，包括静脉重复畸形，较为常见，对静脉手术的结果和疗效有重大影响。数字减影血管造影（DSA）引导下静脉造影是静脉疾病的三级诊断选择，为临床医生提供了有价值的信息。
对 195 例疑似静脉疾病患者进行回顾性研究，对 259 条肢体进行静脉造影图像评估。两名有经验的介入血管科医生评估图像，以确定股静脉、腘静脉、大隐静脉和小隐静脉变异的发生率和特征。此外，采集血样以监测肾功能变化来评估静脉造影术的安全性。
下肢静脉存在重复畸形，股静脉发生率最高（11.28%，22/195），其次是大隐静脉（4.1%，8/195）和腘静脉（1.54%，3/195）。无严重造影剂过敏或术后并发症报道。无重复畸形的患者、大隐静脉、股静脉或腘静脉重复的患者，手术前后血肌酐和尿素水平无统计学差异（<0.05）。
DSA 引导下静脉造影术能有效识别下肢疾病的静脉变异。DFV 是最常见的复发性静脉，而 DPV 是最少见的。充分的准备可确保安全性、高空间分辨率、动态成像和低组织干扰。
