Plain English Summary

Background and study aims
Peripheral arterial disease is a condition where fatty deposits build up in the arteries and restrict the blood supply to the leg muscles. Endovascular interventions (procedures that are done inside the blood vessels) have recently become the procedure of choice, in most cases, for the diagnosis and treatment of peripheral arterial disease. Over 5,000 endovascular procedures are performed annually in Spain for the diagnosis and treatment of PAD. An arterial access is required to perform these procedures. At first this was obtained by surgical dissection, but nowadays this step is avoided in most of cases thanks to the development of percutaneous techniques, where access is achieved through needle-puncture of the skin. Despite the advantages, these techniques pose other associated problems such as those related to the arterial puncture and stopping bleeding at the end of the procedure. After the procedure there are different arterial closure strategies that include direct manual compression over the puncture site, the use of mechanical devices to assist compression and, more recently, the use of percutaneous arterial closure devices. There are several mechanisms of action for these devices, and the most widely used are the collagen plug, percutaneous sutures and hemostatic clips. The use of these systems involves a risk of complications resulting from lack of effectiveness at stopping bleeding and inadequate delivery of the device. The available scientific evidence concerning these devices is scarce and of poor quality in many cases, with most results based on diagnostic procedures performed on the coronary (heart) arteries, which are not applicable to interventions performed on peripheral arteries. The aim of this study is to demonstrate that percutaneous arterial closure devices reduce the time needed to stop bleeding after percutaneous arterial access procedures performed on peripheral arteries, without decreasing the effectiveness and without increasing the risk of complications compared with manual compression.

Who can participate?
Patients aged over 18 undergoing percutaneous arterial access procedures for the diagnosis or treatment of peripheral arterial disease

What does the study involve?
Once the percutaneous arterial access procedure is finished, participants are randomly allocated to one of the following procedures to stop bleeding: collagen plug, metallic clip, suture mediated, or manual compression at the puncture site for at least 10 minutes and for additional periods of 5 minutes until bleeding stops. The effectiveness of the procedures is assessed by observing the absence of bleeding through the puncture site. The time needed to completely stop the bleeding is measured. The occurrence of complications related to the arterial puncture is assessed by physical examination and ultrasound performed 24 hours and 1 month after the intervention.

What are the possible benefits and risks of participating?
The results of this study can help to find out whether these devices are safe and effective in patients with peripheral arterial disease, who usually have more diseased arteries which are more complicated to puncture and have a higher risk of complications. If these devices can be safely used, many patients will have a better recovery with shorter hospital stays and will be able to walk sooner. The possible risks of these devices are acute arterial occlusion (blockage), infection, bleeding and/or hematoma (a solid swelling of clotted blood).

Scientific title

Effectiveness and safety of three percutaneous arterial closure devices (collagen plug, metallic clip and suture mediated) compared to manual compression in hemostasis after percutaneous transfemoral arterial procedures in peripheral territories

Acronym

Study hypothesis

Percutaneous arterial closure devices achieve hemostasis in the arterial femoral access faster than standard manual compression, without increasing the risk of complications related to arterial access site and improving the comfort of the patients.

Condition

Peripheral arterial disease

Intervention

Patients are assigned randomly, by means of a computer generated number, at the end of the procedure to receive hemostasis of the femoral arterial access site with one of the three arterial closure devices tested (collagen plug [Angioseal], metallic clip [Starclose] or suture mediated [Perclose ProGlide]) or manual compression at the puncture site for at least 10 minutes and for additional periods of 5 minutes until complete hemostasis is achieved.

Effectiveness of the hemostatic procedures will be assessed by observation of the absence of bleeding through the puncture site. Time necessary to achieve complete hemostasis will be measured. Occurrence of any complication related to the arterial puncture will be assessed by physical examination and ultrasonography performed 24 hours and 1 month after the intervention.

Primary outcome measures

Effectiveness of the hemostatic procedure applied, assessed by observation of the absence of bleeding through the puncture site immediately after the application of the hemostatic system, 24 hours later and 1 month later

Secondary outcome measures

Occurrence of complications related to arterial access site, assessed by postprocedure physical examination, echo doppler at the arterial access, and blood test at 24 hours and 1 month post intervention
