Abstract: Background: Ultrasound-guided thrombin injection (UGTI) has become the method of choice in the treatment of pseudoaneurysm caused by endovascular procedures because it is minimally invasive, costs less, and effective, with short hospitalization time. The objective was identify the morphological aspects of femoral pseudoaneurysms and clinical aspects of patients that may lead to the failure of UGTI in femoral pseudoaneurysms after cardiac catheterization. Population and Method: From December 2012 to December 2016, 60 patients with pseudoaneurysms caused by cardiac catheterization were referred to the interventional radiology unit to be treated with UGTI. Medical charts were retrospectively reviewed for comorbidities, use of antiplatelet agents, anticoagulation, indication of cardiac catheterization, and so forth. Morphological aspects of the pseudoaneurysms such as volume, diameter (anteroposterior, laterolateral, and longitudinal), length, and diameter of the neck were analyzed. Results: Technical success of UGTI was achieved in 100%. No clinical aspects of the patients were statistically significant for UGTI failure in occlusion of the pseudoaneurysms. For morphological aspects of pseudoaneurysm: anteroposterior (P = 0.029), longitudinal (P = 0.020), and neck diameters (P = 0.004) were statistically significant for UGTI failure. Logistic regression analysis for longitudinal diameter showed that for each centimeter, there was a 2.66 chance of failure of pseudoaneurysm thrombosis in a single thrombin injection session (95% confidence interval: 1.33-5.30). For longitudinal and neck diameters greater than 1.8 cm and 0.55 cm, respectively, there is a greater probability of needing more than one UGTI session for complete thrombosis. Conclusions: Among variables, the longitudinal dimension was more significant, and in a larger diameter, the treatment with thrombin injection presented greater complexity.
