Abstract：
Exostosis (also known as osteochondroma) is the most common benign bony lump of young people, usually arising at the distal femur. Vascular complications associated with exostoses are rare and include true aneurysm or pseudoaneurysm formation, deep vein thrombosis, arteriovenous fistula, and arterial insufficiency of the limbs. Few case reports describe pseudoaneurysms resulting from exostoses in mature adults, and no consensus has been reached regarding the optimal therapy. We report the case of a 51-year-old male patient complaining of persistent right thigh pain with a pulsatile mass and right calf swelling, without a history of trauma or hereditary multiple exostoses. The diagnosis was confirmed by computed tomography angiography, which showed a pseudoaneurysm of the popliteal artery resulting from an exostosis on the lateral aspect of the distal femur. A Doppler ultrasound examination confirmed popliteal vein thrombosis caused by the compression of the pseudoaneurysm. Surgical treatment consisted of removing the exostosis, excision of the pseudoaneurysm, and an end-to-end anastomosis. The deep vein thrombosis was treated with rivaroxaban for 3 months. The patient was discharged after 6 days and followed up for 6 months with satisfactory results.
摘要：
骨外生症（又称骨软骨瘤）是年轻人最常见的良性骨性肿块，通常出现在股骨远端。与外生体相关的血管并发症很少见，包括真正的动脉瘤或假性动脉瘤形成。深静脉血栓形成,动静脉瘘,和四肢动脉供血不足.很少有病例报告描述成熟成人外生体引起的假性动脉瘤。尚未就最佳治疗达成共识。我们报告了一个51岁的男性患者，抱怨持续的右大腿疼痛伴搏动性肿块和右小腿肿胀，没有外伤或遗传性多发性外生骨。诊断通过计算机断层扫描血管造影证实，显示股骨远端外侧的骨外生症导致pop动脉假性动脉瘤。多普勒超声检查证实了由假性动脉瘤压迫引起的the静脉血栓形成。手术治疗包括切除外生体，切除假性动脉瘤,和端到端吻合。深静脉血栓使用利伐沙班治疗3个月。6天后出院,随访6个月,效果满意。
