近年,随着临床介入治疗的广泛应用,医源性股动脉假性动脉瘤的发生率呈增加趋势,有学者报道其发生率约为0.3%~8.0%~([1])。医源性股动脉假性动脉瘤多发生于经皮股动脉穿刺的各种介入诊断和治疗操作后,形成机制和病理基础为动脉内血液经动脉壁的穿刺口流到血管周围的组织内,形成一个或者多个瘤腔,瘤壁没有正常动脉壁的内膜、中膜和外膜结构,而是由局部形成的血肿机化吸收而形成,多为纤维组织构成,动脉血流于收缩期经瘤颈部流入瘤腔内,于舒张期血流
In recent years, with the widespread use of clinical intervention, the incidence of iatrogenic femoral artery pseudoaneurysm is increasing. Some scholars have reported that its incidence is about 0.3% ~ 8.0% ~ ([1]). Iatrogenic femoral pseudoaneurysm occurred in the percutaneous femoral artery puncture after a variety of interventional diagnosis and treatment operations, the formation mechanism and pathological basis for the arterial blood flow through the arterial wall flow into the perivascular tissue, The formation of one or more tumor cavity, tumor wall without normal arterial wall of the intima, media and adventitia, but by the local formation of hematoma machine to absorb and form, mostly fibrous tissue, arterial blood flow during systole The tumor neck into the tumor cavity, in diastolic blood flow
