Endovascular therapy as the primary approach for limb salvage in patients with critical limb ischemia: experience with 443 infrapopliteal procedures.

Abstract: Endovascular strategies for the treatment of critical infrageniculate peripheral arterial occlusive disease exist and are becoming the primary methodology for such lesions at many centers. Although technically feasible for experienced operators, the evidence to support this strategy for below the knee (BTK) interventions is still evolving. We studied the 6-month and 1-year outcomes of percutaneous transluminal angioplasty (PTA) alone, PTA with stenting, and excimer laser recanalization for BTK lesions in patients with critical limb ischemia. Between September 2002 and June 2005, 443 patients (355 Rutherford category 4, 82 category 5, 6 category 6) underwent intervention for 681 BTK lesions. Follow-up was performed at 6-month intervals after index intervention: limb salvage data were recorded and duplex ultrasonography was performed to measure the patency of treated areas. The primary patency and limb salvage rates of the entire population were 85.2% and 97.0% and 74.2% and 96.6% at 6 months and 1 year, respectively. Stratified for the treatment strategy (PTA alone in 79, PTA with stenting in 300 patients, and excimer laser in 64), 1-year primary patency rates were 68.6%, 75.5%, and 75.4%, whereas the limb salvage rates were 96.7%, 98.6%, and 87.9% for each modality, respectively. Endovascular intervention will become the primary treatment for BTK lesions in patients with critical limb ischemia, with 1-year primary patency and limb salvage rates that compare favorably with published surgical data. Prospective, randomized, multicenter trials will be needed to further establish the role of endovascular intervention in this challenging patient group.

Matrix Metalloproteinases in Vascular Physiology and Disease

Abstract: Matrix metalloproteinases (MMPs) are a family of zinc-dependent endopeptidases that primarily degrade components of the extracellular matrix (ECM). Remodeling of the ECM by MMPs is important in both physiological and pathological processes, including organ generation/regeneration, angiogenesis, wound healing, inflammation and tumor growth. In the vasculature, MMPs play a role in beneficial processes such as angiogenesis, collateral artery formation and thrombus resolution. However, MMP expression is also implicated in the pathogenesis of vascular diseases such as atherosclerosis, aortic aneurysms, plaque rupture and neointimal hyperplasia after balloon angioplasty. Here, we review the structure, functions and roles of MMPs in both neovascularization and vascular pathology and discuss the potential of, and challenges that face, adapting MMPs as therapeutic targets in vascular disease.

Management of Surgical Hemostasis: Topical Agents

Abstract: Intraoperative control of bleeding during any surgical procedure is vital for achieving a positive patient outcome. Hemostasis can be achieved through practical and effective systemic or topical approaches. A variety of hemostatic methods can be employed, ranging from simple manual pressure application with one finger to electrical tissue cauterization, systemic administration of blood products, and systemic administration or topical application of procoagulation agents. The key to surgical success is critically dependent on knowledgeable use of a method appropriate for the level of bleeding experienced by the patient. Topical agents can be effective as adjuncts to aid in hemostasis when bleeding is not controllable with pressure application, vessel ligation, or electrocautery. Such adjunctive hemostatic treatments include topical gelatins, collagens, oxidized celluloses, thrombin and fibrin sealants, synthetic glues, and glutaraldehyde-based glues. As with the use of systemically delivered hemostatic agents, topical treatments also carry risks with their use, and their efficacy has not been extensively studied in large randomized, placebo-controlled prospective studies. The effective use of topical agents is highly dependent on the surgeon's experience or preference and their availability in the surgical setting. In this article, we review the currently available topical hemostatic agents, compare their efficacy, and give general recommendations for their use in the operating room.

Application Of Energy-based Technologies And Topical Hemostatic Agents In The Management Of Surgical Hemostasis

Abstract: Achieving intraoperative hemostasis is essential for excellent surgical outcomes. A variety of methods, ranging from mechanical tools and energy-based technologies to topical hemostatic agents, are available to the modern surgeon. Given that bleeding develops from different origins, from small discrete bleeding or venous oozing to arterial hemorrhage, different tools and agents have different efficacy in specific situations. In this article, we review the mechanism by which currently available hemostatic tools and agents stop bleeding and give recommendations for their use during surgery. Furthermore, the costs of the various methods are presented, allowing the provider to choose not only the most potent but also the most cost-effective treatment modality in each situation.
