The prospectively generated results of 64 duplex sonographic examinations in 59 patients being evaluated for peripheral pseudoaneurysms over a 2-year period were reviewed. Subsequently, two groups of patients were identified. Group 1 (45 examinations) presented with relatively acute symptoms after arterial puncture, and group 2 (19 examinations) had undergone previous vascular surgical procedures and were usually asymptomatic. Duplex sonography demonstrated high sensitivity (94%) and specificity (97%) for the diagnosis of pseudoaneurysm in group 1. Of the 19 studies in group 2, duplex sonography allowed correct identification of pseudoaneurysms in four studies and exclusion of this entity in six examinations. The duplex sonographic findings in nine studies in this group did not allow differentiation of pseudoaneurysm from true aneurysm or oversize graft anastomosis. Duplex sonography is suggested as a primary radiologic method for evaluating possible pseudoaneurysms after arterial puncture, and it may provide valuable information and a means of postsurgical follow-up of selected patients as well.
回顾了在两年时间里对59例接受外周假性动脉瘤评估的患者进行的64次双功超声检查的前瞻性结果。随后，确定了两组患者。第1组（45次检查）在动脉穿刺后出现相对急性的症状，第2组（19次检查）曾接受过血管外科手术，通常无症状。双功超声检查对第1组假性动脉瘤的诊断显示出高敏感性（94%）和特异性（97%）。在第2组的19项研究中，双功超声检查在4项研究中正确识别了假性动脉瘤，在6次检查中排除了该病变。该组9项研究中的双功超声检查结果无法区分假性动脉瘤与真性动脉瘤或过大的移植吻合口。双功超声检查被建议作为评估动脉穿刺后可能的假性动脉瘤的主要放射学方法，并且它也可能为选定患者提供有价值的信息和术后随访手段。
