PURPOSE: To evaluate whether ultrasound (US) assistance can decrease the rate of complications related to the use of vascular closure devices (VCDs). MATERIALS AND METHODS: A retrospective comparative study was done on 150 consecutive patients who had a VCD inserted under US guidance after retrograde common-femoral-artery (CFA) puncture. This group was compared to a historical control group of 150 consecutive patients who had the same VCDs inserted with the standard blind technique. After the procedures, patients were placed at bedrest for at least 6 h. Technical success, defined as correct deployment without adjunctive manual compression, blood count and US evaluation of the arterial puncture site was done at 24 h and at 3 months. Differences in terms of efficacy and safety were statistically evaluated using US guidance as a predictor for a lower complication rate. RESULTS: Technical success was achieved in 147/150 patients (98 %) in the study group vs. 141/150 cases (94 %) of the control group (p = 0.038). In three cases (2 %) adjunctive manual compression (≤5 min) was required. One pseudoaneurysm (0.65 %) occurred after 24 h, solved with manual compression. Six minor complications (4 %)--haematoma (n = 5; 3.35 %), recurrent wound bleeding (n = 1; 0.65 %)--were reported. In the control group four (2.65 %) major complications occurred: CFA occlusion managed with surgical bypass, CFA dissection solved by surgical bypass, two pseudoaneurysms solved with manual compression. Thirteen (8.65 %) minor complications were observed with haematoma (n = 10; 6.65 %), and recurrent wound bleeding (n = 3; 2.0 %). The comparative analysis of the total complication rate and major complication rate between the study group and the control group was statistically significant (p = 0.016 and p = 0.049, respectively). A 24-h evaluation showed a triphasic flow within the CFA in 150/150 patients (100 %) of the study group and in 146/150 cases (97.35 %) of the control group. CONCLUSION: VCD inserted under US guidance increases the success rate reducing the number of complications.
