The Value of 3D CE-MRA in Diagnosis of Pseudoaneurysm in Femoral Artery

Objective To evaluate the value of three dimensional contrast enhanced MRA(3D CE-MRA) in the diagnosis of pseudoaneurysm in femoral artery.Methods 19 cases with pseudoaeurysm of femoral artery (including broken in 1 case) were examined by 3D CE-MRA and the imaging features were compared with pathologic and surgical results.Results 18 pseudoaneurysms were clearly displayed in 19 cases (one broken did not showed).The ascidial pseudoaneurysm usually closely contiguous with the parent artery,connections as the wide basal bodies were found in 11 patients and as the narrowing neckes were found in 6 patients between the pseudoaneurysm and the parent artery,but one did not showed.The pseudoaneurysms located at femoral artery in 7,at initiation of deep femoral artery in 10 and at deep femoral artery in 1.The collateral branch vessals were displayed in 6 patients.Conclusion 3D CE-MRA is of important value in diagnosis and treatment of pseudoaneurysm of femoral artery.
