Pseudoaneurysm of superior lateral genicular artery following total knee arthroplasty is a rare complication and has been reported following lateral release performed for eversion of patella in a knee with tight lateral structures.
This report describes a case of pseudo aneurysm of superior lateral geniculate artery that developed after primary Total knee arthroplasty for a stiff knee in a 68 year old patient. Patient presented with pain and rapidly increasing swelling in early post operative period. Diagnosis was made on duplex ultrasound and confirmed by angiography. Angiographic coil embolisation of the pseudoaneurysm was performed. Since no lateral release was performed in this case, the probable mechanism was shear injury to the vessel.
Pseudoaneurysm of superior lateral genicular artery can occur in absence of lateral release by shear injury to an atherosclerotic vessel. Angiographic coil embolisation appears to be the best method for treating such post arthroplasty pseudoaneurysm because of less chance of infection, non interference with rehabilitation and diagnosis and treatment during same procedure.
全膝关节置换术后膝上外侧动脉假性动脉瘤是一种罕见的并发症，在膝关节外侧结构紧张时为纠正髌骨外翻而进行外侧松解后曾有过相关报道。
本报告描述了一例68岁患者因膝关节僵硬行初次全膝关节置换术后发生膝上外侧动脉假性动脉瘤的病例。患者在术后早期出现疼痛和迅速加重的肿胀。通过双功超声做出诊断，并经血管造影证实。对假性动脉瘤进行了血管造影弹簧圈栓塞术。由于该病例未进行外侧松解，可能的机制是血管受到剪切损伤。
膝上外侧动脉假性动脉瘤可在未进行外侧松解的情况下因动脉粥样硬化血管受到剪切损伤而发生。血管造影弹簧圈栓塞术似乎是治疗此类置换术后假性动脉瘤的最佳方法，因为感染几率较低，不干扰康复进程，且可在同一操作过程中完成诊断和治疗。
