Cystic degeneration of the adventitia of the popliteal artery is a rare clinico-angiographic diagnosis in the chronic ischaemia syndrome of the lower extremity. If the three cardinal signs occur concomitantly, namely, intermittent ischaemia syndrome, unilocular manifestation near the joint and clearly limited filling defect in the arteriogram, diagnosis can be made with a high measure of certainty. Among our angiographically examined patients, we observed, in the course of one year, three male patients who presented the full picture of the disease with regard to clinic, localisation and angiographic findings. Intraoperatively it was not possible to establish a connection between adventitia cyst and neighbouring articular capsule; this applies, in fact, to all our cases. Histologically we found in one case, in the hollow spaces of the adventitia, an indication of the possible existence of a synovial recess, so that the scattering of mucine-secreting endothelium of the joint into the vascular adventitia is again brought up for discussion.
腘动脉外膜的囊性退变是下肢慢性缺血综合征中一种罕见的临床血管造影诊断。如果同时出现三个主要体征，即间歇性缺血综合征、关节附近的单房表现以及动脉造影中明显局限性的充盈缺损，就可以高度确定地做出诊断。在我们接受血管造影检查的患者中，在一年的时间里，我们观察到三名男性患者在临床、定位和血管造影表现方面都呈现出该疾病的全貌。术中无法在外膜囊肿与相邻关节囊之间建立联系；事实上，我们所有的病例都是如此。组织学上，我们在一个病例的外膜空腔中发现了滑膜隐窝可能存在的迹象，因此关节分泌粘蛋白的内皮细胞向血管外膜的散布问题再次被提出来讨论。
