Background/aim: Evaluate the risk factors associated with pseudoaneurysms' development after the percutaneous interventional procedures performed by cardiology, interventional radiology (IR), and the other clinics., Materials and Methods: We retrospectively analyzed the ultrasound scans in the hospital database and picture archiving system (PACS) and enrolled a total of 132 patients during the period from October 2015 and December 2019. We evaluated the maximum diameter and volume of the pseudoaneurysm with the patient and procedure-related factors with univariate analysis., Results: We found that the patients with hypertension and without peripheric artery disease (PAD) had greater sac diameter (p = 0.010 and p = 0.016) and increased sac volume (p = 0.029 and p = 0.007). However, the sac volume increased in patients with diabetes than those without (p = 0.003). Both the increased maximum diameter and the volume of the pseudoaneurysm sac were in the patients in whom the procedure was applied in the common femoral artery (CFA) and with the venous intervention (p < 0.010 and p < 0.016; p = 0.004 and p = 0.001, respectively). We found that platelet count correlated negatively with the sac's maximum diameter and the volume (r = –0.383, p < 0.001 and r = –0.486, p < 0.001, respectively) duration of intervention correlated positively with the sac's maximum diameter and the volume (r = 0.205, p = 0.019 and r = 0.320, p < 0.001)., Conclusion: Our study reveals that prolonged procedure duration, simultaneous arterial and venous accesses, peripheral artery disease, thrombocytopenia, and puncture site are the aggressive risk factors of pseudoaneurysms size after angiographic procedures., Competing Interests: No conflict of interest was declared by the authors., (This work is licensed under a Creative Commons Attribution 4.0 International License.)
