Objective   To evaluate the roles of color Doppler ultrasound in the diagnosis and treatment of the complications correlated with puncture of femoral artery after percutaneous transluminal interventional procedure.     Methods   The images by Doppler and the results of treatment under the guide of Doppler in 39 cases with complications correlated with puncture of femoral artery after percutaneous transluminal interventional procedure were studied retrospectively. The effects of color Doppler ultrasound on the diagnosis and treatment of the complications correlated with puncture of femoral artery after percutaneous transluminal interventional procedure were investigated.     Results   The complications correlated with puncture of femoral artery in 39 cases included 16 cases of pseudoaneurysm

11 cases of edema of tissue around the artery

17 cases of hematoma

and 4 cases of arteriovenous fistula formation. There were 11 cases with multiple complications. After pressure of the point of puncture under the guide of color Doppler

the arteriovenous shunt and murmur were eliminated in 4 cases with pseudoaneurysm and 3 cases with arteriovenous fistula. Only 1 case with arteriovenous remained unvarnished and transcatheter stent-graft placement was performed to obturate the rupture of femoral artery. Injection of thrombin with Doppler was performed in 12 cases with pseudoaneurysm and eliminated arteriovenous shunt was achieved in 10 cases at 24 h. After the second injection in 1 case and the third time in another case

eliminated arteriovenous shunt was achieved.     Conclusion   Color Doppler ultrasound may play a very important role in the diagnosis and treatment of the complications correlated with puncture of femoral artery after percutaneous transluminal interventional procedure.
