A completely thrombosed aneurysm of the popliteal artery may mimic a simple vascular occlusion both clinically and angiographically. If therapeutical interventions are planned for recanalisation a popliteal aneurysm must be excluded because in such cases vascular surgery is the method of choice. In 11 of 26 patients with an angiographically proven unilateral popliteal occlusion, contrast CT could demonstrate an aneurysm (unilateral n = 7, bilateral n = 4). Real time sonography could confirm unilateral thrombosed aneurysm in 10 of 11 cases; a partially thrombosed contralateral aneurysm was detected in all 4 cases. In contrast to a non-reliable palpable finding both US and or CT are useful in detecting an aneurysmatic degeneration of the popliteal artery. Previous identification of an aneurysm of the abdominal aorta or femoral artery may be helpful in patient selection.
腘动脉完全血栓形成的动脉瘤在临床和血管造影上可能与单纯血管闭塞相似。如果计划进行再通的治疗干预，必须排除腘动脉瘤，因为在这种情况下血管手术是首选方法。在26例血管造影证实为单侧腘动脉闭塞的患者中，有11例通过对比CT可显示动脉瘤（单侧7例，双侧4例）。实时超声在11例中有10例可证实为单侧血栓形成的动脉瘤；在所有4例中均检测到对侧部分血栓形成的动脉瘤。与不可靠的触诊结果不同，超声和CT在检测腘动脉的动脉瘤样变性方面均很有用。先前对腹主动脉或股动脉瘤的识别可能有助于患者的选择。
