Analysis of the Presence of Clot in the Femoral Arterial Introducer During Angiography: A Randomized Clinical Trial

Percutaneous angiography has been performed for decades, but it is not without complications, such as the formation of a clot within the arterial introducer, and its potential migration into the systemic circulation.However, it is not clear what the best approach is regarding the use of continuous perfusion in the introducer (pressure perfusion through the lateral port of the introducer with saline solution 0.9%) during diagnostic angiographic exams, in preventing the formation of clots inside the introducer, which is the access portal for the passage of catheters and guide wires.Objective: To determine the frequency of clot presence in the femoral artery introducer with and without continuous perfusion in cerebral angiographic studies. Method:A randomized clinical trial in patients undergoing cerebral angiography performed at the Hospital das Clnicas / EBSERH-UFPE and at Angiocor in Joo Pessoa -Paraba, divided into two groups: Control group (GC), n=34 patients without continuous perfusion in the femoral arterial introducer during angiography.Experimental group (GE), n=34 patients with continuous perfusion in the femoral arterial introducer during angiography.Statistical analysis was performed using the u Mann-Whitney test, for continuous variables and the Fisher's exact test for categorical variables.The significance level was 0.05. Results:In the GC there was the presence of a clot in all introducers at the end of the angiographic exam, while in the GE, no clot was present in any introducers at the end of the angiographic exam. Conclusion:The use of continuous infusion prevented the formation of clots within the introducer during the angiographic exam in all cases.
