Ultrasonography is accurate for diagnosis of abdominal aneurysms and clots within them. However, due to technical factors, occlusive clots within the aorta can be missed even at high gain. The authors report three cases in which total occlusion of the abdominal aorta was misdiagnosed as a free lumen occupied by a small clot. An explanation for the shortcomings of ultrasound is offered.
超声检查对于诊断腹主动脉瘤及其内部的血栓是准确的。然而，由于技术因素，即使在高增益情况下，主动脉内的闭塞性血栓也可能被漏诊。作者报告了三例腹主动脉完全闭塞被误诊为被小血栓占据的自由管腔的病例。文中对超声检查的不足之处给出了解释。
