The transfemoral arterial approach is used to gain access for angiography, percutaneous coronary interventions, or various endovascular therapies. To decrease the risk of procedure-related vascular complications, it is recommended to puncture the common femoral artery in its middle segment. However, due to inadequate access or anatomical variability, various complications, including hematoma, pseudoaneurysm, arteriovenous fistula, thrombosis, or dissection, can occur after transfemoral arterial interventions. Duplex ultrasound has proven to be an excellent noninvasive modality that provides not only anatomic but also hemodynamic information, effectively detecting and differentiating various femoral puncture-related complications. Radiologists should be familiar with the characteristic sonographic findings of the entire spectrum of transfemoral puncture-related vascular complications for early detection and proper treatment.
经股动脉途径用于进行血管造影、经皮冠状动脉介入治疗或各种血管内治疗。为降低与手术相关的血管并发症风险,建议在股总动脉中段进行穿刺。然而,由于入路不足或解剖变异,经股动脉介入治疗后可能会出现各种并发症,包括血肿、假性动脉瘤、动静脉瘘、血栓形成或夹层。双功超声已被证明是一种出色的无创检查方法,不仅能提供解剖信息,还能提供血流动力学信息,可有效检测和鉴别各种与股动脉穿刺相关的并发症。放射科医生应熟悉经股动脉穿刺相关血管并发症的全谱特征性超声表现,以便早期发现并进行恰当治疗。
