2024 TSOC/TSPS Joint Consensus: Strategies for Advanced Vascular Wound Management in Arterial and Venous Diseases.

The Taiwan Society of Cardiology (TSOC) and Taiwan Society of Plastic Surgery (TSPS) have collaborated to develop a joint consensus for the management of patients with advanced vascular wounds. The taskforce comprises experts including preventive cardiologists, interventionists, and cardiovascular and plastic surgeons. The consensus focuses on addressing the challenges in diagnosing, treating, and managing complex wounds; incorporates the perfusion evaluation and the advanced vascular wound care team; and highlights the importance of cross-disciplinary teamwork. The aim of this joint consensus is to manage patients with advanced vascular wounds and encourage the adoption of these guidelines by healthcare professionals to improve patient care and outcomes. The guidelines encompass a range of topics, including the definition of advanced vascular wounds, increased awareness, team structure, epidemiology, clinical presentation, medical treatment, endovascular intervention, vascular surgery, infection control, advanced wound management, and evaluation of treatment results. It also outlines a detailed protocol for assessing patients with lower leg wounds, provides guidance on consultation and referral processes, and offers recommendations for various wound care devices, dressings, and products. The 2024 TSOC/TSPS consensus for the management of patients with advanced vascular wounds serves as a catalyst for international collaboration, promoting knowledge exchange and facilitating advancements in the field of advanced vascular wound management. By providing a comprehensive and evidence-based approach, this consensus aims to contribute to improved patient care and outcomes globally.

Integrating new approaches to care in a vascular wound clinic.

INTRODUCTION: An evidence-based approach is essential in the treatment of wounds to optimise healing, reduce costs and improve patient outcomes. AIM: This case study aimed to demonstrate our model of care, which assesses and manages patients with venous disease and complex wounds. In this case, venous leg ulcer (VLU) was treated with TLC-NOSF dressing and therapeutic compression. The wound was serially assessed using a smart App that gave the patient a graphic representation of their progress. DESIGN: Descriptive Observational Case Study. CLINICAL CARE: An evidence-based approach for managing a chronic, severe VLU. The patient was initially seen at the Outpatient Vascular Wound Clinic twice weekly, then every two weeks for conservative sharp wound debridement, skin care, dressing change, and compression therapy using a compression (Ready) wrap. Wound progress was monitored by the digital application 'Tissue Analytics', a "purposedesigned digital wound management platform that records, tracks, and analyses wounds". RESULTS: Week 1: On initial review, ulcer length was 3.15cm, width was 3.1 cm, and total surface area was 6.31 cm2. The wound base was mildly sloughy (<25%), with areas of good granulation tissue on view. Week 12: Length was 1.32 cm, width 1.50 cm, and total surface area of 1.45 cm2, a 77% reduction in wound size. Week 24: The length was 0.48 cm, the width was 0.64 cm, and the total surface area was 0.18 cm2. This represented a 97% reduction in wound size. Week 36: Length was 0.01 cm, the width 0.06 cm, with a total surface area of 0.00 cm2. This represented a 99.99% reduction in wound size. CONCLUSION: The patient's treatment for a complex venous leg ulcer included the application of TLC-NOSF dressing in combination with individualised therapeutic compression therapy. We found TLC-NOSF was very effective in combination with the best standard of VLU care (i.e. therapeutic graduated compression therapy). The clinician and patient were impressed with the healing rate at 12 weeks, as the wound dimensions were the lowest since the wound started six years ago. This dramatically improved patient concordance and engagement in care. Despite incomplete healing at 36 weeks, the wound-healing journey over the 36 weeks indicated wound closure was close. In addition, using a wound assessment App, the patient could immediately see the benefits of the new treatment, facilitating patient compliance with the treatment.

Management of war-related vascular wounds in French role 3 hospital during the Afghan campaign.

OBJECTIVES: To describe the management of war-related vascular injuries in the Kabul French military hospital. METHODS: From January 2009 to April 2013, in the Kabul French military hospital, we prospectively included all patients presenting with war-related vascular injuries. We collected the following data: site, type, and mechanism of vascular injury, associated trauma, type of vascular repair, amputation rate and complications. RESULTS: Out of the 922 soldiers admitted for emergency surgical care, we recorded 45 (5%) patients presenting with vascular injuries: 30 (67%) gunshot-related, 11 (24%) explosive device-related, and 4 (9%) due to road traffic accident. The majority of injuries (93%) involved limbs. Vascular injuries were associated with fractures in 71% of cases. Twelve (26.7%) had an early amputation performed before evacuation. Twenty (44.4%) patients underwent fasciotomy and three (6.6%) sustained a compartment syndrome. CONCLUSIONS: This was the first French reported series of war-related vascular injuries during the last decade's major conflicts. The majority of injuries occurred in the limbs. Autologous vein graft remains the treatment of choice for arterial repair. Functional severity of these injuries justifies specific training for military surgeons.

MicroRNAs and the response to injury in atherosclerosis.

Endothelial cells (ECs) at arterial branching points are physiologically subjected to chronic damage by disturbed blood flow, which triggers a vascular wound healing response. Additional damage by hyperlipidaemia perturbs this delicate balance of endothelial injury and regeneration, and the progressive accumulation of noxious modified lipoproteins leads to macrophage death. Several miRNAs such as miR-92a and miR-712, which modulate EC proliferation and inflammation, are up-regulated by disturbed flow in ECs, and contribute to atherosclerosis. In addition, reduced endothelial levels of miR-126-5p limit the regenerative capacity of ECs, which becomes apparent by insufficient endothelial repair under hyperlipidemic stress. In macrophages, miR-342-5p induces the expression of miR-155 during the progression of atherosclerosis, which promotes inflammatory gene expression and inhibits efferocytosis by targeting Bcl6, thus contributing to necrotic core formation. Deciphering the complex cell- and context-specific effects of miRNAs during vascular wound healing appears essential for the development of miRNA-based therapies of atherosclerosis.

Effects of low-dose candesartan on the rate of re-endothelialisation following vascular wound healing.

The wound healing response of the vascular wall to injury involves re-endothelialisation of the denuded luminal surface and thickening of the intimal area (intimal hyperplasia), as expressed by the intimal-to-medial area ratio (I/M). Candesartan, at doses of 1 mg/kg/day or higher, has been reported to attenuate the intimal hyperplastic response. We tested the hypothesis that candesartan, at doses lower than those associated with attenuation of intimal hyperplasia, may affect re-endothelialisation. New Zealand White rabbits were subjected to balloon catheter injury to the thoracic aorta. Candesartan, at doses of 50, 100, and 500 µg/kg/day, was delivered via an Alzet pump placed in the abdomen one week prior to aortic injury. There was no attenuation of the hyperplastic response of the aortic wall. However, at 50 µg/kg/day the rate of reendothelialisation was significantly increased. These data suggest that candesartan may exhibit pleiotropic effects on vascular wound healing, in addition to the well-known effect of attenuating the development of intimal hyperplasia.
