Twenty-three patients with ischemic disease of the legs referred for routine preoperative angiography were examined with intra-arterial DSA and high resolution ultrasonography with duplex-Doppler to detect inguinal lymph nodes. None of the patients had evidence of malignant or lymphomatous disease and only 3 had skin ulceration on the foot. DSA detected nodes in 9 patients (39%). In 3 cases the nodes were highly vascularized. Ultrasonography detected lymph nodes in 16 patients (70%). In all but 2 nodes a high velocity arterial flow was recorded. It is concluded that DSA and particularly duplex-Doppler ultrasonography are sensitive methods to detect vascularized lymph nodes and that such nodes are found in many patients with no evidence of malignancy or infection.
23例因腿部缺血性疾病接受常规术前血管造影的患者，接受了动脉内数字减影血管造影（DSA）和高分辨率双功能多普勒超声检查以检测腹股沟淋巴结。所有患者均无恶性或淋巴瘤疾病证据，仅有3例足部有皮肤溃疡。DSA在9例患者（39%）中检测到淋巴结。3例中淋巴结血管高度丰富。超声检查在16例患者（70%）中检测到淋巴结。除2个淋巴结外，其余所有淋巴结均记录到高速动脉血流。结论是，DSA尤其是双功能多普勒超声是检测血管化淋巴结的敏感方法，且在许多无恶性肿瘤或感染证据的患者中可发现此类淋巴结。
