The aim of the present study is an evaluation, whether an immobilization of the upper extremity by means of a positioning splint can help to reduce the incidence of local complications after transbrachial puncture for peripheral arterial interventions, or not.

Increasing numbers of peripheral arterial interventions are performed via transbrachial access leading to a higher number of local complications at the puncture site. Patients are demonstrating complications, such as hematoma, false aneurysm, secondary hemorrhage and arterial stenosis or occlusion.

Due to not standardized post-interventional procedure regarding to immobilization a higher risk for local puncture site complication can occur. Usually, a compression bandage its applied to the brachial puncture site. Within this randomized study, patients randomized to the study group will receive an additional splint for 24 hours to ensure an immobilization of the affected arm.

Following the removal of the compression dressing, and the splint in the study group, a duplex ultrasound its performed in order to detect local alterations and pathologies of the brachial artery.

This examination is repeated for each patient in the course of an outpatient control six weeks post-interventionally. Pathologies are documented and treated if necessary.

Inclusion Criteria:

• Female and male patients suffering from peripheral arterial occlusive disease with indicated interventions via an transbrachial access (puncture of the left or right brachial artery)
• age > 18 years
• approval to participate

Exclusion Criteria:

• unability or refusal to participate
• dialysis patients/AV-fistula interventions
• usage of closure devices
