April 2, 2009 - TCA Cellular Therapys Medical Director Gabriel Lasala, M.D. presented preliminary results of an adult stem cell treatment for severe limb ischemia Sunday at the American College of Cardiologys first annual i2 Summit.. Lower limb ischemia is a condition where plaque build-up causes decreased circulation in the lower leg. Symptoms of the condition include intense pain and swelling.. Lasala, together with the companys Scientific Director Jose Minguell, Ph.D., treated 10 patients during the Phase I safety/efficacy clinical trial using a combination of the patients own endothelial progenitor cells (EPCs) and mesenchymyal stem cells (MSCs). The cells, obtained through bone marrow aspiration, were mixed and infused into damaged veins.. According to Lasala, there were no adverse effects as a result of the infusions. More importantly, their patients experienced a progressive improvement in all clinical parameters, which are still persisting a year after treatment.. "All patients ...
August 6, 2018 - WAYNE, Pa.-(BUSINESS WIRE)-Intact Vascular, Inc., a developer of medical devices for minimally invasive peripheral vascular procedures, today announced key presentations that will be featured during a CME symposium at the Amputation Prevention (AMP) Conference in Chicago on August 8.. The symposium, titled "Why Dissections Matter: A case-based look at below-the-knee lesions post-PTA" will explore how post-percutaneous transluminal angioplasty (PTA) dissections are often overlooked, underdiagnosed and left untreated. These dissections can compromise clinical outcomes in both the short and long term, thus putting limbs at increased risk of reduced blood flow, gangrene and amputation. The symposium will feature three critical limb ischemia experts: George Adams, MD, Marianne Brodmann, MD and Peter Soukas, MD.. "The effect of post-angioplasty dissection in lower extremities, or below-the-knee, is particularly detrimental in patients with critical limb ischemia," said George Adams, ...
Any ABPI value ,1.2 should be interpreted with caution, as calcification and hardening of the arteries may cause a falsely high ABPI.. Any critical limb ischaemia should be investigated initially with a Doppler ultrasound, used to assess the severity and anatomical location of any occlusion. Further imaging can be achieved via CT angiography or MR angiography (MRA).. Due to concurrent cardiovascular risk factors seen in patients with chronic limb ischaemia, patients should also have a cardiovascular risk assessment. This includes blood pressure, blood glucose, lipid profile and ECG.. In addition, any patient presenting with chronic limb ischaemia ,50yrs without significant risk factors should also have a thrombophilia screen and homocysteine levels* checked.. *A lower homocysteine level has been associated with reduced risk of cardiovascular events. ...
Acute limb ischaemia (ALI) occurs when there is a sudden lack of blood flow to a limb. Acute limb ischaemia is caused by embolism or thrombosis, or rarely by dissection or trauma. Thrombosis is usually caused by peripheral vascular disease (atherosclerotic disease that leads to blood vessel blockage), while an embolism is usually of cardiac origin. In the United States, ALI is estimated to occur in 14 out of every 100,000 people per year. With proper surgical care, acute limb ischaemia is a highly treatable condition; however, delayed treatment (beyond 6 to 12 hours) can result in permanent disability, amputation, and/or death. The New Latin term ischaemia as written, is a British version of the word ischemia, and stems from the Greek terms ischein to hold; and haima blood. In this sense, ischaemia refers to the inhibition of blood flow to/through the limb. Acute limb ischaemia can occur in patients through all age groups. Patients that smoke and have diabetes mellitus are at a higher risk ...
A review of data from Veteran Health Administration shows that there was a temporal increase in the use of revascularisations for the management of critical limb ischaemia between 2005 and 2014. This increase correlated with a reduction in both mortality and major amputation during the same time period. However, contrary to data for non-veteran association patients, the new data did not indicate a shift towards endovascular revascularisation strategies.. Amgad Mentias (University of Iowa Carver College of Medicine, Iowa City, USA) and others write in Circulation: Cardiovascular Interventions that prior studies of non-veteran patients have already shown a temporal increase in both the use of revascularisation and the use of statin therapy for the management of critical limb ischaemia, and these trends have been linked to a reduction in mortality. "However, contemporary studies of critical limb ischaemia incidence, clinical management, and outcomes among veterans remain limited," the authors ...
Background: There is strong interest in bone marrow-derived mononuclear cells (BM-MNCs) for therapeutic enhancement of ischemia-mediated neovascularization. However, clinical trials to date have yielded contradictory results. We hypothesize that varying cell number and delivery routes may contribute to these inconsistencies. Using bioluminescent imaging we longitudinally evaluate the effects of cell number and delivery route on therapeutic efficacy, homing, survival and engraftment of BM-MNCs in a murine model of hindlimb ischemia.. Methods and Results: The contribution of BM-MNCs in ischemia-mediated neovascularization was assessed via intramuscular (IM) or intravenous (IV) transplantation of BM-MNCs (2x105/1x106) that were extracted from the bone marrow of transgenic FVB-L2G mice (ubiquitously expressing Fluc and GFP reporter genes) and injected into syngeneic FVB/N mice after surgery (n=5-6/group). Recovery was monitored with Laser Doppler Perfusion Imaging. IM treatments of 1x106 cells ...

Limb salvage was possible in all six diabetic patients with Fontaine stage IV CLI following autologous BM MNC injection. The procedure was safe without any adverse outcomes.
We examined short- and long-term outcomes of tibial and peroneal venous and heparin-bonded expanded polytetrafluoroethylene bypasses in patients with critical limb ischemia who were unsuitable for endovascular revascularization. ...
Despite advances in surgical and radiological vascular techniques, a significant number of patients with chronic critical limb ischaemia (CLI) are not eligible for revascularization procedures, often leaving amputation as the only option. Consequently, exploring new strategies for revascularization of ischemic limbs is of major importance. Preclinical studies and pioneering clinical trials suggest that administration of bone marrow (BM) mononuclear cells (MNC) into ischemic limbs enhances neovascularization, improves tissue perfusion and prevents amputation. However, no definite proof is available as the clinical studies thus far have been small and lacked double-blinded controls.. JUVENTAS is a randomized, double-blinded placebo-controlled trial in 109 - 160 patients with CLI to investigate the potential clinical effects of repeated intra-arterial infusion of BM-MNC in these patients (the exact number of patients to be included cannot be specified in advance because of the planned group ...
Using autologous bone marrow mononuclear cells (BM-MNC) to treat patients with chronic limb ischemia has been proved safe and effective. However, processing bone marrow by Ficoll density gradient centrifugation is not only time consuming but also expensive. Manually processing of bone marrow also results in large variation in therapeutic cell quantity and quality which directly lead deviation of safety and efficacy of the cell therapy. This study is aiming to compare an automated bone marrow processing system with a conventional manual method in term of safety and efficacy.. ResQ system developed by Thermogenesis in USA provides an automatic cell processing system for bone marrow. The system takes less than 30 minutes to concentrate the therapeutic mononuclear cells including stem cells in a closed system without adding any additive such as separation reagent (Ficoll). The system also be able to be operated at point of care.. The study is designed to prove no inferior of safety and efficacy of ...
The main result of this study is that CXCR3 expression positively modulates ischemia-induced neovascularization, likely through modulation of inflammatory cell infiltration within the ischemic area. This study also extends previous results on the role of MCP-1 in this process and shows a significant impairment in postischemic neovascularization in MCP-1-deficient mice.. Classically, inflammatory cells have been shown to promote neovascularization through various mechanisms, including production of angiogenic factors, secretion of proinflammatory cytokines, and increased matrix degradation.7-9 LPS-induced monocyte accumulation promotes vessel growth, whereas absence of macrophages is associated with a deficient neovascularization response.10,11 A specific role of T cells in this setting was also suggested in Nude mice and in CD4-deficient mice, which exhibit a marked reduction in the angiogenic/arteriogenic process.4,5 In this study, we showed that CXCR3 and its ligands CXCL-10 and CXCL-9 were ...

Critical limb ischemia (CLI), also referred to as limb threat, is an advanced stage of peripheral artery disease. It is defined as a triad of ischemic rest pain, arterial insufficiency ulcers, and gangrene. The latter two conditions are jointly referred to as tissue loss, reflecting the development of surface damage to the limb tissue due to the most severe stage of ischemia. CLI has a negative prognosis within a year after the initial diagnosis, with 1-year amputation rates of approximately 12% and mortality of 50% at 5 years and 70% at 10 years.. CLI was conceived to identify patients at high-risk for major amputation, but the increasing prevalence of diabetes mellitus has led to a broader conception of limb threat that includes the risk of amputation associated with severely infected and non-healing wounds.. ...
Doctors give unbiased, trusted information on the use of Stress Test for Ischemia: Dr. Hammoud on apical ischemia stress test: Most hearts have physiologic apical thinning which can sometimes be misinterpreted on nuclear stress test images. In addition, stress test images in patients with left bundle branch block can appear as septal ischemia if exercise stress is done rather than pharmacologic. The fact that both the apex and septum are involved in your case make it more likely to be real ischemia probably in lad.
Gene therapy stimulating the growth of blood vessels is considered for the treatment of peripheral and myocardial ischemia. Here we aimed to achieve angiogenic synergism between vascular endothelial growth factor-A (VEGF-A, VEGF) and fibroblast growth factor 4 (FGF4) in murine normoperfused and ischemic limb muscles. Adeno-associated viral vectors (AAVs) carrying β-galactosidase gene (AAV-LacZ), VEGF-A (AAV-VEGF-A) or two angiogenic genes (AAV-FGF4-IRES-VEGF-A) were injected into the normo-perfused adductor muscles of C57Bl/6 mice. Moreover, in a different experiment, mice were subjected to unilateral hindlimb ischemia by femoral artery ligation followed by intramuscular injections of AAV-LacZ, AAV-VEGF-A or AAV-FGF4-IRES-VEGF-A below the site of ligation. Post-ischemic blood flow recovery was assessed sequentially by color laser Doppler. Mice were monitored for 28 days. VEGF-A delivered alone (AAV-VEGF-A) or in combination with FGF4 (AAV-FGF4-IRES-VEGF-A) increased the number of capillaries in normo
Peripheral Arterial Diseases (PAD) is a chronic and debilitating disease caused due to narrowing and hardening of arteries, that results in progressive deterioration of blood flow to the limbs. PAD commonly occurs in the presence of multiple comorbidities, including hypercholesterolemia, diabetes, obesity and stroke. On average one in twenty individuals over the age of 60 have some degree of arterial claudication and it worsens with age. Two thirds of the patients suffering from PAD develop a pathological condition called Critical Limb Ischemia (CLI). Limb ischemia induces severe hypoxia and degeneration of blood vessels resulting in irreversible damage manifested by gangrene or necrosis. 30% of those with CLI will require amputation within one year of diagnosis and 25% will die from circulatory complications. Several surgery-based endovascular interventions are only beneficial for patients with fewer occlusions and availability of autologous vein grafts. Delivery of genes and growth factors ...
Dr. Walker responds to a letter to the editor that considers the question of whether critical limb ischemia patients should undergo angiography to detect coronary artery disease.
The term therapeutic angiogenesis is a concept that had first been introduced by the German gynecologist Michael Höckel in 1989 [1]. The idea was to induce capillary growth in order to improve regional tissue perfusion and to improve tissue viability following surgery. Much has happened in the field since then. Major angiogenesis factors and their receptors have been identified, isolated, cloned and characterized. Preclinical data has accumulated which clearly proves the concept that angiogenic growth factors are capable of inducing vascular and collateral growth. This had been shown for VEGF-A, for bFGF as well as for other growth factors [2]. Proof of concept had been achieved in animal models of both peripheral ischemia and regional myocardial ischemia in the early 1990s.. The concept of collateral artery growth has been modified by the introduction of the term "arteriogenesis", which describes the growth of mature arteries [3] of large caliber. The prevailing concept is that these mature ...
OBJECTIVE: factors regulating transcapillary fluid transport were investigated to elucidate the causes of oedema in CLI. MATERIAL: sixteen patients, 6 men and 10 women (mean age of 79+/-10.3 years) with unilateral CLI and peripheral pitting oedema. M
Substance P (SP) is a therapeutic peptide that has been widely used to induce angiogenesis and tissue regeneration. However, its therapeutic efficacy is often limited due to rapid degradation in vivo and a short half-life (1 min) after systemic administration. In the present study, we chemically modified SP with polyethylene glycol (PEG) to generate long-lasting formulations with increased stability and extended retention time in vivo and evaluated their ability to enhance therapeutic angiogenesis. Compared to the unmodified SP, PEGylated SP (PEG-SP) exhibited significantly increased half-life in vivo ('360-fold increase in normal mouse and (similar to)120-fold increase in diabetic mouse). Systemic injection of PEG SP led to a marked increase in therapeutic efficacy and angiogenesis in diabetic hindlimb ischemia, as evident from the remarkable improvement in salvage of ischemic limb and recovery of blood perfusion in diabetic mice with limb ischemia. These formulations increased endogenous ...

The aim of this study was to examine the outcomes in patients presenting with critical ischemia owing to below-the-elbow arterial atherosclerotic disease who underwent nonoperative and operative management. Methods: A database of patients undergoing operative and nonoperative management for symptomatic below-the-elbow atherosclerotic disease between 2006 and 2016 was retrospectively queried. Patients with critical ischemia (tissue loss and rest pain) were identified. Three management groups were identified: no revascularization (None), endovascular revascularization (Endo), and open revascularization by bypass ...
Critical limb ischemia (CLI) is a severe blockage in the arteries of the lower extremities, which markedly reduces blood-flow. It is a serious form of peripheral arterial disease, or PAD, but less common than claudication. PAD is caused by atherosclerosis, the hardening and narrowing of the arteries over time due to the buildup of fatty deposits called plaque.. CLI is a chronic condition that results in severe pain in the feet or toes, even while resting. Complications of poor circulation can include sores and wounds that wont heal in the legs and feet. Left untreated, the complications of CLI will result in amputation of the affected limb.. ...
A Randomized Double Blind Placebo Controlled Clinical Study to Assess Blood-Borne Autologous Angiogenic Cell Precursors Therapy in Patients With Critical Limb Ischemia
Background: Patients with Critical Limb Ischemia (CLI) have a high risk of amputations and mortality. We hypothesize that inflammation is involved in atherosclerotic disease progression. In this study we investigate whether levels of plasma cytokines are associated with disease progression in CLI.. Methods: Data were collected from a randomized controlled trial cohort investigating cell therapy for CLI (the JUVENTAS study) from 2006 to 2012. The primary outcome measures were major amputation and mortality at 6 months; secondary outcomes included Ankle/Brachial Index (ABI) and Transcutaneous O2 Pressure. Plasma was collected at inclusion in the study and a panel of cytokines consisting of GROa, HGF, LIF, SCF, SCGFb, SDF1a, TRAIL, IL-6, IL-8, FGFb, GCSF, GMCSF, IP10, MCP1, PDGFbb, RANTES, TNFa and VEGF was measured and evaluated for predictive power.. Results: Data on 108 patients was collected with a follow-up of 6 months. Patients who underwent a major outcome had significantly higher levels of ...

Seek immediate medical care if you have sudden, severe abdominal pain. Pain that makes you so uncomfortable that you cant sit still or find a comfortable position is a medical emergency.. If you have other signs or symptoms that worry you, make an appointment with your doctor.. Intestinal ischemia occurs when the blood flow through the major arteries that supply blood to your intestines slows or stops. The condition has many potential causes, including a blockage in an artery caused by a blood clot, or a narrowing of an artery due to buildup of deposits, such as cholesterol. Blockages also can occur in veins, but theyre less common.. Whatever the cause, diminished blood flow within your digestive tract leaves cells without enough oxygen, which causes the cells to weaken and die. If damage is severe enough, infection, gangrene and eventually a hole (perforation) in the wall of the intestines can occur. If untreated, intestinal ischemia can be fatal.. Intestinal ischemia is often divided into ...

Nelson Bernardo, MD, medical director for Peripheral Vascular Intervention at MHVI and director for Peripheral Interventional Research Studies at MedStar Cardiovascular Research Network, is leading a feasibility study of an investigational revascularization technique called LimFlow™.. The LimFlow System is currently indicated as a treatment for patients with end-stage CLI who have no other revascularization option-and have failed either endovascular or surgical interventions, or even both. "The procedure is based on a concept devised some time ago for use in the heart to bypass occluded coronary arteries," says Dr. Bernardo.. The LimFlow procedure entails the creation of a fistula from an artery in the leg to its accompanying vein. The latter carries the oxygenated blood flow into the critically ischemic foot via venous pedal arch acting as the arterial system. The vein is accessed distally at the level of the ankle while the artery is accessed at the groin area using the antegrade femoral ...
December 1, 2016-A prospective, multicenter, observational study evaluated the safety and effectiveness of tibiopedal access and retrograde crossing in the treatment of infrainguinal chronic total occlusions (CTOs). The study demonstrated that tibiopedal access appears to be safe and can be used effectively for the crossing of infrainguinal lesions in patients with severe lower limb ischemia. Craig M. Walker, MD, et al published the studys findings in the Journal of Endovascular Therapy (JEVT; 2016;23:839-846).. The study was conducted at 12 sites around the world from May 2012 to July 2013. Investigators prospectively enrolled 197 patients (mean age, 71 ± 11 years; range, 41-93 years; 129 men) who met the inclusion criterion of at least one CTO for which a retrograde crossing procedure was planned or became necessary. The study population was composed of 64 (32.5%) claudicants (Rutherford categories 2/3) and 133 (67.5%) patients with critical limb ischemia (Rutherford category ≥ 4).. The ...
