Retrospective Evaluation Of Ultrasound In Iatrogenic Pseudoaneurysm

Objective:To evaluate the value of ultrasound in the diagnosis and treatment of pseudoaneurysm after cardiac interventional surgeryMethod:Retrospective analysis of the clinical and ultrasound data in 107 patients diagnosed as pseudoaneurysm after cardiac intervention surgery between October 2017 to October 2018 in Fuwai hospital.Result:the study analyses 107 patients who were diagonosed as pseudoaneurysm after cardiac intervention from oct 2017 to oct 2018.60 of them are male and 47 of them are female.their mean age of 61.7±14.0 years,85 patients have hypertension,74 patients have hyperlipidemia,the mean BMI was 24.9 ± 3.7,and LVEF was 59.7±0.8%.The median time from operation to ultrasound diagnosis was 2 days.In this study,the average size of the pseudoaneurysm was(31.6±16.7)mm×(15.5±7.6)mm,and the color Doppler can all show"yin-yang sign”and Spectral Doppler of the 80%pseudoaneurysm can show "double-period and double-direction" blood stream spectrum in the PAS neck.Of the 107 patients,65 are treated by compression dressing,55 of them are located in the femoral artery with a success rate of 78%.The mean maximal diameter of PAS treated successfully was(28.86 ± 15.40)mm;14 patients requiring ultrasound-guided hematoma aspiration with manual compression therapy are performed in the femoral artery with a success rate of 100%,and the The mean maximal diameter of PAS was approximately(36.71±16.55)mm.7 patients undergoing ultrasound-guided thrombin injection and 4 in the upper extremity artery,the success rate was 100%.The mean maximal diameter of PAS was(28.42±15.86)mm;5 undergoes surgical repair,and 3 cases were located in the upper extremity artery.The success rate was 100%,The mean maximal diameter of PAS was(40.50±13.92)mm.Conclusion:Ultrasound plays an indispensable role in the diagnosis and treatment of PAS before and after cardiac intervention.The size of PAS is helpful to guide the treatment of pseudoaneurysms.The older,the obesity and the hypertension are often associated with the incidence of pseudoaneurysms.Femoral artery is the most common iatrogenic pseudoaneurysm,and the radial artery pseudoaneurysms develop slowly.The examination of puncture site should be took routinely after cardiac intervention,especially in patients with high-risk factors,which can help clinical diagnosis and treatment.
