Over a 24-month period, 21 patients underwent duplex Doppler evaluation for arterial injury secondary to catheterization. There were seven pseudoaneurysms, one arteriovenous fistula, eight hematomas, and one true aneurysm. Duplex ultrasound was 100% sensitive and specific for detection of pseudoaneurysms and arteriovenous fistulas. The real-time examination alone was unreliable. The only necessary criterion for diagnosis of a femoral pseudoaneurysm was the presence of pulsatile flow in a cystic collection separate from the common femoral artery. This could be determined rapidly. Arterial flow in the femoral vein confirmed the presence of an arteriovenous fistula.
在24个月的时间里，21例患者因导管插入术继发的动脉损伤接受了双功多普勒评估。其中有7例假性动脉瘤、1例动静脉瘘、8例血肿和1例真性动脉瘤。双功超声对假性动脉瘤和动静脉瘘的检测敏感性和特异性均为100%。仅靠实时检查并不可靠。诊断股部假性动脉瘤的唯一必要标准是在与股总动脉分开的囊性积液中存在搏动性血流。这一点可以迅速确定。股静脉中的动脉血流证实了动静脉瘘的存在。
