Intraoperative Application of Cold Atmospheric Plasma to Prevent Postoperative Wound Complications in the Inguinal Region of High-risk Patients With Peripheral Arterial Occlusive Disease (PICPAD)
Prophylactic Application of Cold Atmospheric Plasma to Reduce Postoperative Wound Healing Disorders in the Inguinal Region in High-risk Patients With Peripheral Arterial Occlusive Disease- Intraoperative Application of Cold Atmospheric Plasma in the Inguinal Region
The goal of this clinical trial is to learn if postoperative wound complications in the inguinal region of high-risk patients with peripheral arterial occlusive disease can be prevented by the intraoperative application of cold atmospheric plasma.
The main questions it aims to answer are:
Does the intraoperative application of cold atmospheric plasma reduce the need for surgical revision of inguinal wounds due to wound healing complications within 3 months postoperatively? Does the intraoperative application of cold atmospheric plasma reduce wound healing complications not requiring revision within 3 months postoperatively?
Researchers will compare the application of cold atmospheric plasma to a placebo (a deactivated look-alike device).
Participants will:
Undergo surgical treatment with femoral artery access due to their peripheral arterial occlusive disease, in accordance with the respective vascular surgery department standard of care.
Receive a single application of cold atmospheric plasma or, respectively, placebo in the area of their inguinal access wound during surgery (after subcutaneous closure and prior to skin closure).
Be regularly assessed for wound healing during the first postoperative 14 days as part of routine clinical care and undergo a final evaluation at 3 months. They will also be surveyed regarding their quality of life.

Patients will be provided with the EQ-5D-5L (European Quality of Life 5 Dimensions 5 Level Version) questionnaire in order to assess quality of life at the baseline visit as well as follow-up visits 3 and 4 and after 3 months (end of study visit). The EQ-5D-5L will be evaluated by converting responses across its five domains-mobility, self-care, usual activities, pain/discomfort, and anxiety/depression-into a single health utility index using a country-specific value set (e.g., German tariff), with possible values typically ranging from below 0 (worse than death) to 1 (full health). Each domain is rated on a 5-level scale, where 1 = no problems, 2 = slight problems, 3 = moderate problems, 4 = severe problems, and 5 = extreme problems/unable to perform. In addition, the EQ Visual Analogue Scale (EQ VAS) score will be analyzed separately, ranging from 0 (worst imaginable health) to 100 (best imaginable health). |
