(CS-004) Treatment of Complicated Post-Operative Vascular Wounds: Utilizing a Novel Transforming Powder Dressing in Lieu of Conventional Wound Dressings
Introduction: Management of surgical site wounds and complications is an important consideration for any vascular surgery team. Patients desire a dressing which is pain-free, easy to apply and requires minimal dressing changes and manipulation. This case series evaluates the use of a novel transforming powder dressing (TPD) with extended wear time (up to 30 days) as a wound dressing option in managing amputation sites and incisional surgical wounds complicated by dehiscence. TPD is a powder dressing that transforms upon hydration to form an oxygen permeable matrix that covers and protects the wound.
Methods: We performed an observational case series assessment on post-surgical wounds in two patients with severe vascular pathology and significant co-morbidities. TPD was used as an alternative to conventional wound dressings. Patient demographics, past medical and surgical history, and anatomical pathology were described. Evaluation of wound closure progress was followed with the participation of multi-specialty teams.
Results: (1): 78 y/o male with history of diabetes, coronary artery disease (s/p CABG and TAVR), COPD, and PAD presented with non-healing infected ulcer of left hallux. Patient underwent angiogram with intervention and ultimately amputation of left first hallux and distal aspect of the first metatarsal. Patient continued weekly wound care with TPD with significant reduction in wound surface area and pain at amputation site.
(2): 72 y/o male with history of hypertension, CKD3, A-fib, MI, and severe PVD with rest pain presented with postoperative surgical site infection and wound dehiscence following right femoral endarterectomy. TPD was used at home resulting in reduced pain and complete wound closure of incisional wound.
Discussion: Both patients experienced remarkable wound healing results and reduced pain using TPD. Based on these results, we concluded that TPD is an appropriate treatment for use in the post-surgical setting that may be easily and competently managed by a patient at home. TPD provided the benefit of promoting wound healing, while being a less expensive alternative to other modalities that require more frequent dressing changes. It also allowed for ease of use in both clinic and home settings, significantly reducing the need of office visits for dressing changes.
