TY - JOUR. T1 - Endovascular-First Treatment Is Associated With Improved Amputation-Free Survival in Patients With Critical Limb Ischemia. AU - Lin, Jonathan H.. AU - Brunson, Ann. AU - Romano, Patrick S. AU - Mell, Matthew. AU - Humphries, Misty. PY - 2019/8/1. Y1 - 2019/8/1. N2 - BACKGROUND: Critical limb ischemia remains a difficult disease to treat, with limited level one data. The BEST-CLI trial (Best Endovascular vs Best Open Surgical Therapy in Patients with Critical Limb Ischemia) is attempting to answer whether initial treatment with open surgical bypass or endovascular therapy improves outcomes, although it remains in enrollment. This study aims to compare amputation-free survival and reintervention rates in patients treated with initial open surgical bypass or endovascular intervention for ischemic ulcers of the lower extremities. METHODS AND RESULTS: Using California nonfederal hospital data linked to statewide death data, all patients with lower extremity ulcers and a diagnosis of ...
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 ...

Seventy per cent of all critical limb ischaemia is in low and middle income countries, which might seem surprising, Yost said. Explaining why, aside from the fact that low-middle income countries have higher populations, she continued, The age-specific prevalence of peripheral arterial disease is similar in the high and low-middle income countries and is similar in men and women. However, and this is key, peripheral arterial disease was significantly higher in women under the age of 60 years in low-middle income countries. Finally, and very importantly, there is a high and rapidly growing prevalence of diabetes in low-middle income countries. The significance of the growing prevalence of diabetes is underscored by the fact that it increases relative risk of for critical limb ischaemia by six to seven times, and for peripheral arterial disease by two to four times-a very strong risk factor, Yost said.. Yost explained how the unique characteristics of diabetes in low-middle income countries ...
Research on the epidemiology of peripheral artery disease (PAD) and critical limb ischemia (CLI) in Japan is sparse to nonexistent.. The prevalence of diabetes is rapidly increasing worldwide. Diabetes has grown at a faster rate in Asia than in Western countries, reaching epidemic proportions in the region. Over the last several decades, the number of diabetics in Japan has risen significantly, reflecting the combination of growing obesity, decline in physical activity and the aging population.. Employing the Diabetes Method, the 2015 prevalence of PAD and CLI is estimated for Japan, and the prevalence of each is projected for the 2015-2030 period. PAD and CLI incidence estimates are also included for 2015-2030. PAD prevalence in recently published Japanese studies is assessed and compared with THE SAGE GROUP estimates.. The number of symptomatic and asymptomatic Japanese PAD cases is estimated for 2015-2030 with specific estimates for intermittent claudication (IC) and critical limb ischemia. ...
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
In animal experiments, use of molecular hydrogen ( H2) has been regarded as quite safe and effective, showing benefits in multiple pathological conditions such as ischemia-reperfusion injury of the brain, heart, kidney and transplanted tissues, traumatic and surgical injury of the brain and spinal cord, inflammation of intestine and lung , degenerative striatonigral tissue and also in many other situations. However, since cerebral ischemia patients are in old age group, the safety information needs to be confirmed. For the feasibility of H2 treatment in these patients, delivery of H2 by inhalation method needs to be checked for consistency. Hydrogen concentration (HC) in the arterial and venous blood was measured by gas chromatography on 3 patients, before, during and after 4% (case 1) and 3% (case2,3) H2 gas inhalation with simultaneous monitoring of physiological parameters. For a consistency study, HC in the venous blood of 10 patients were obtained on multiple occasions at the end of 30-min H2
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 ...

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 ...

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..

TY - JOUR. T1 - Rarefaction of peritubular capillaries following ischemic acute renal failure. T2 - A potential factor predisposing to progressive nephropathy. AU - Basile, David P.. PY - 2004/1. Y1 - 2004/1. N2 - Purpose of review: Long-term renal complications of acute renal failure have generally not been expected in patients that recover from acute renal failure. However, as the incidence of acute renal failure is rising, the incidence of long-term complications is likely to increase. As a corollary to ischemic acute renal failure, ischemic injury in the setting of transplant is a leading cause of delayed graft function. Unlike acute renal failure in native kidneys, delayed graft function is highly predictive of chronic nephropathy and organ failure. It is generally well accepted that acute reversible injuries mediated by ischemia render grafts susceptible toward future demise. The nature of the susceptibility that is conveyed to grafts following ischemic injury is not well understood. ...

Abdulsalam Y Taha*, Nazar Q [email protected] & Akeel S Yousr# *Department of Cardiothoracic & Vascular Surgery, School of Medicine, University of Sulaimaniyah and Sulaimaniyah Teaching Hospital, Sulaimaniyah, Region of Kurdistan. @#Department of Cardiothoracic & Vascular Surgery, Ibn-Alnafis Teaching Hospital, Baghdad, Iraq. Abstract Femoropopliteal bypass (FPB) refers to revascularization of the ischemic lower limb using venous or synthetic graft to bypass occluded superficial femoral or proximal popliteal artery. Our aim was to evaluate the outcome of FPB for critical limb ischemia (CLI) or severe intermittent claudication (IC) in 2 vascular centres in Baghdad, Iraq. Forty eight patients (39 male) with CLI or IC were studied over 19 months. The mean age was 57.5±13.2 yr. All except 5 were studied retrospectively by medical charts review. Diagnosis included Doppler ultrasonography (DUS) and angiography. Standard operative technique was followed. Atherosclerosis was the main etiology (n=45, 93.7%).
Acute mesenteric ischemia is a relatively rare but often fatal clinical entity. Although little data exist on its true incidence, data from the Swedish Vascular Registry suggest that it may account for just 1% of reconstructions for acute thromboembolism.1 Contemporary series, however, continue to report a mortality rate of between 32% and 48%.2,3 Although autopsy studies suggest that atherosclerosis affecting the mesenteric arteries is common (6%-10%),4 symptomatic mesenteric occlusive disease is rare. However, of patients presenting with acute mesenteric ischemia, one large series found that 43% had prior symptoms of chronic mesenteric ischemia.5 The spectrum of mesenteric ischemia includes occlusive disease secondary to atherosclerotic occlusion with thrombosis, embolism, mesenteric venous thrombosis, and nonocclusive mesenteric ischemia due to vasospasm (Table 109-1).

AU - Tsai, Hsiao Ya. AU - Wang, Chao Hung. AU - Chen, Yung Hsiang. AU - Chen, Jia Shiong. AU - Lin, Feng Yen. AU - Lin, Chih Pei. AU - Wu, Tao Cheng. AU - Sata, Masataka. AU - Chen, Jaw Wen. AU - Lin, Shing Jong. PY - 2010/10. Y1 - 2010/10. N2 - Objective: Circulating endothelial progenitor cells (EPCs) play a significant role in postnatal neovascularization. Patients with diabetes have attenuated EPC functions and impaired angiogenic response after tissue ischemia. We investigated whether moderate red wine consumption can enhance blood flow recovery in response to tissue ischemia by enhancement of EPC functions in diabetic mice. Methods and results: Starting at 4 weeks after diabetes onset, red wine (4ml/kg/day) or ethanol were administered to streptozotocin (STZ)-induced (type 1) diabetic mice and KKAy-Ta (type 2) ...
The present study used a gene-targeting strategy to establish a novel role for EC-derived MMP-2 in neovascularization. We provided both in vitro and in vivo evidence that MMP-2 promotes the migratory and angiogenic capacity of cultured aortic EC and BM-derived EPC-like c-Kit+ cells and further neovessel growth. In line with recent studies indicating that certain MMPs are involved in EPC mobilization, our data underscore the critical role of MMP-2 in EPC mobilization into the circulation to support ischemia-induced neovascularization. The mechanisms underlying the impairment of ischemia-induced neovascularization in MMP-2-deficient mice are schematically represented in supplemental Figure X.. The capillary density, collateral artery, and blood flow in the ischemic tissues were much lower in MMP-2−/− mice than in MMP-2+/+ mice, despite the compensatory increase of MMP-9 expression and its activity and TIMP-1 expression. This suggested that endogenous MMP-2 contributes to ischemia-induced ...
Acute neonatal limb ischaemia (NLI) is most frequently an iatrogenic complication, however, may also occur in utero due to thromboembolism. There is no widely accepted protocol for treatment of NLI and limited evidence to guide management. Thrombolysis and surgical management have been attempted, though both are associated with significant morbidities. Milrinone is a phosphodiesterase-3 inhibitor used for its vasodilatory effects on the systemic and pulmonary vasculature. There is also emerging evidence for benefit of milrinone in ameliorating ischaemia-reperfusion injury. The authors present a case report of a term infant with spontaneous perinatal acute limb ischaemia secondary to near-completely occlusive thrombosis of the right subclavian artery. The infant was successfully managed conservatively with milrinone without requirement for thrombolysis or surgical intervention. Milrinone represents a novel treatment option for neonates with acute limb ischaemia and consideration of a trial of ...
Objective- Recent clinical studies of therapeutic neovascularization using angiogenic growth factors demonstrated smaller therapeutic effects than those reported in animal experiments. We hypothesized that nanoparticle (NP)-mediated cell-selective delivery of statins to vascular endothelium would more effectively and integratively induce therapeutic neovascularization.. Methods and Results- In a murine hindlimb ischemia model, intramuscular injection of biodegradable polymeric NP resulted in cell-selective delivery of NP into the capillary and arteriolar endothelium of ischemic muscles for up to 2 weeks postinjection. NP-mediated statin delivery significantly enhanced recovery of blood perfusion to the ischemic limb, increased angiogenesis and arteriogenesis, and promoted expression of the protein kinase Akt, endothelial nitric oxide synthase (eNOS), and angiogenic growth factors. These effects were blocked in mice administered a nitric oxide synthase inhibitor, or in eNOS-deficient ...

The primary endpoint was major adverse events ...
Background: Monocyte signaling is a dominant and important mediator of arteriogenesis activity and monocyte-signaling responses can be severely impaired during arteriogenesis in various vascular disorders. Hydrogen sulfide (H2S) is produced by cystathionine-γ lyase (CSE), and a potential gasotransmitter that has many positive cardiovascular effects including regulation of monocyte functions. However, molecular mechanisms of monocyte specific H2S regulation of arteriogenesis remain completely unknown.. Hypothesis: Monocyte specific H2S production modulates arteriogenesis during hind limb ischemia via a CSE/H2S/IL-16/bFGF dependent pathway.. Methods: Unilateral hind limb ischemia was induced in WT and CSE-/- mice. Mice were then randomly assigned into 4 groups (8 mice, each group); WT PBS, WT DATS (a hydrogen sulfide donor, 200 μg/kg bid., IV until day 21), CSE-/- PBS, CSE-/- DATS. Monocyte expression and activity of CSE and H2S levels was determined in ischemic conditions both in vitro and in ...

N2 - Background: The possible relation between menopause and the development of peripheral arterial disease, especially lower extremity disease, has not been fully studied. To explore this issue, we investigated whether estrogen deficiency affected neovascularization in a murine model of hindlimb ischemia. Methods: Ischemia was surgically induced in one hindlimb of oophorectomized and control female BALB/c mice. Neovascularization in the ischemic hindlimbs was evaluated using laser Doppler blood flow analysis and capillary density analysis of the adductor muscle. The expression of endothelial nitric oxide synthase protein in the adductor muscle of the ischemic hindlimbs was assessed. Results: The plasma 17-β ...
The Outcome of Percutaneous Transluminal Angioplasty in Patients with Critical Limb Ischemia and how Diabetes May Influence this Outcome Abstract.
Patients with severe critical limb ischemia (CLI) due to long tibial artery occlusions are often poor candidates for surgical revascularization and frequently end up with a lower limb amputation. Subintimal angioplasty (SA) offers a minimally invasive alternative for limb salvage in this severely compromised patient population. The objective of this study was to evaluate the results of SA in patients with CLI caused by long tibial occlusions who have no surgical options for revascularization and are facing amputation. We retrospectively reviewed all consecutive patients with CLI due to long tibial occlusions who were scheduled for amputation because they had no surgical options for revascularization and who were treated by SA. A total of 26 procedures in 25 patients (14 males; mean age, 70 +/- A 15 [SD] years) were evaluated. Technical success rate was 88% (23/26). There were four complications, which were treated conservatively. Finally, in 10 of 26 limbs, no amputation was needed. A major ...
Brain ischemia (a.k.a. cerebral ischemia, cerebrovascular ischemia) is a condition in which there is insufficient blood flow to the brain to meet metabolic demand. This leads to poor oxygen supply or cerebral hypoxia and thus to the death of brain tissue or cerebral infarction / ischemic stroke. It is a sub-type of stroke along with subarachnoid hemorrhage and intracerebral hemorrhage. Ischemia leads to alterations in brain metabolism, reduction in metabolic rates, and energy crisis. There are two types of ischemia: focal ischemia, which is confined to a specific region of the brain; and global ischemia, which encompasses wide areas of brain tissue. The main symptoms involve impairments in vision, body movement, and speaking. The causes of brain ischemia vary from sickle cell anemia to congenital heart defects. Symptoms of brain ischemia can include unconsciousness, blindness, problems with coordination, and weakness in the body. Other effects that may result from brain ischemia are stroke, ...

This study combines two well-known vascular research models, hyperoxia and hind limb ischemia, aiming to better characterize capacities of the hyperoxia challenge. We studied two groups of C57/BL6 male mice, a control (C) and a hind limb ischemia (HLI) group. Perfusion from both limbs was recorded in all animals by laser Doppler techniques under an oxygen (O 2) saturated atmosphere, once for control and, during 35 days for the HLI group. We used a third set of normoxic animals for HLI morphometric control. The expected variability of responses was higher for the younger animals. In the HLI group, capillary density normalized at Day 21 as expected, but not microcirculatory physiology. In the operated limb, perfusion decreased dramatically following surgery (Day 4), as a slight reduction in the non-operated limb was also noted. Consistently, the response to hyperoxia was an increased perfusion in the ischemic limb and decreased perfusion in the contralateral limb. Only at Day 35, both limbs exhibited
Thromboembolic events have been reported in hospitalized patient since beginning of the covid 19 pandemic. This study reports an ICU admitted patient with lower extremity arterial thrombosis diagnosed with covid 19.
Acute mesenteric ischemia (AMI) is typically defined as a group of diseases characterized by an interruption of the blood supply to varying portions of the small intestine, leading to ischemia and secondary inflammatory changes. If untreated, this process will eventuate in life threatening intestinal necrosis. The incidence is low, estimated at 0.09-0.2% of all acute surgical admissions. Therefore, although the entity is an uncommon cause of abdominal pain, diligence is always required because if untreated, mortality has consistently been reported in the range of 50%. Early diagnosis and timely surgical intervention are the cornerstones of modern treatment and are essential to reduce the high mortality associated with this entity. The advent of endovascular approaches in parallel with modern imaging techniques may provide new options. Thus, we believe that a current position paper from World Society of Emergency Surgery (WSES) is warranted, in order to put forth the most recent and practical
AIM: To evaluate the survival benefit from myocardial revascularization in diabetic patients with critical limb ischemia and coronary artery disease (CAD) in a consecutive series of 564 diabetic patients hospitalized from 1999 to 2003 and followed up until December 2005. METHODS: Three hundred and thirteen patients had a history of CAD, 60 of them (19.2%) with previous myocardial revascularization. Sixty-one patients with an ejection fraction of 40% or less underwent subsequent myocardial revascularization. Five hundred and fifty-seven patients (98.8%) were followed up until December 2005, including 310 of the 313 patients with a history of CAD. RESULTS: One hundred and ten patients died because of CAD, 25 of the 251 patients without a history of CAD and 85 of the 313 patients with a history of CAD. Specifically, 74 (86.9%) of these 85 deaths occurred in the 192 patients without previous myocardial revascularization, nine (10.7%) in the 60 patients with previous myocardial revascularization, and ...
BACKGROUND. Bypass surgery (BS) remains the gold standard revascularization strategy in patients with chronic limb-threatening ischemia (CLTI) owing to infrainguinal disease. The Bypass versus Angioplasty for Severe Ischaemia of the Leg (BASIL)-1 trial showed that, in patients with CLTI who survived for 2 years or more, BS resulted in better clinical outcomes. Despite this finding, there has been an increasing trend toward an endovascular-first approach to infrainguinal CLTI. Our aim was to investigate whether changes in practice have impacted the clinical outcomes of BS in our unit 10 years after BASIL-1.. METHODS. Data for patients who underwent femoropopliteal (FP) BS in BASIL-1 (1999-2004) were retrieved from trial case record forms. The comparator contemporary series (CS) comprised all patients undergoing FP BS for CLTI in our unit between 2009 and 2014. Demographic and clinical outcome data on patients in the CS were collected from the prospectively collected hospital electronic notes. ...

SCS treatment of non-reconstructable critical leg ischaemia provides a significantly better limb survival rate compared with conservative treatment. Patient selection based on TcpO2 and the results of trial screening further increase the probability of limb survival after SCS therapy.
Purpose: To identify the risk factors of major adverse cardiac event (MACE) in patients with chronic atherosclerotic lower extremity ischemia (CALEI) undergoing revascularization without noninvasive stress testing (NIST). Methods: From January 2007 to January 2012, patients with CALEI who underwent revascularization were retrospectively reviewed. Emergent operations, revision procedures for previous surgery, or patients with active cardiac conditions were excluded. NIST was not performed for patients without active cardiac conditions. Cardiac risk was categorized into low, intermediate and high risk, according to the Lees revised cardiac risk index. MACE was defined as acute myocardial infarction or any cardiac death within 30 days after surgery. Results: A total of 459 patients underwent elective lower extremity revascularization procedures (240 open surgeries, 128 endovascular procedures, and 91 hybrid surgeries). The treated lesions comprised of 18% aorto-iliac, 58% infrainguinal, and 24% ...
It has been a long-term goal to develop non-invasive methods that can detect critical levels of tissue hypoxia to help in the management of chronic lower limb ischaemia. In the present study, skeletal muscle oxygenation was measured using a new Clark-type TCPO2 [transcutaneous PO2 (partial pressure of O2)]/PCO2 (partial pressure of CO2) monitoring system and optical NIRS (near-infrared spectroscopy) at graded levels of hypoxaemia using a rabbit model (n=6). The TCPO2/PCO2 probe was placed on the shaved hindlimb to record SPO2 (skin PO2) and SPCO2 (skin PCO2) continuously. A pair of NIRS probes were placed on the limb to monitor HbO2 (oxyhaemoglobin) and Hb (deoxyhaemoglobin). Graded hypoxaemia was achieved by stepwise reductions of FiO2 (fraction of inspired O2) from 30% to 6%. Animals were allowed to recover after each episode of hypoxia at an FiO2 of 30% as indicated by normalized arterial blood PO2. There was a significant (P|0.05) decrease in SPO2 with all grades of hypoxaemia and no significant
Limited data are available regarding prevention of limb ischemia in femorally cannulated patients on venoarterial extracorporeal membrane oxygenation (VA-ECMO). We investigated the association between strategy of distal perfusion catheter (DPC) insertion and vascular complications like limb ischemia in patients undergoing VA-ECMO. We evaluated 230 patients from two tertiary hospitals who received VA-ECMO via femoral cannulation between August 2014 and July 2017. The patients were divided into two groups according to DPC insertion strategy: patients who underwent DPC insertion at the time of primary cannulation (DPC group, n = 96) and patients who were provisionally treated with DPC (No-DPC group, n = 134). The primary outcome was limb ischemia. Of the 96 patients in the DPC group, 61 (63.5%) underwent insertion under fluoroscopic guidance. The DPC group had a significantly lower incidence of limb ischemia (2.1% vs. 8.2%, p = 0.047) and a lower tendency of in-hospital mortality (38.5% vs. 50.7%, p = 0
New research has shown human neural stem cells could improve blood flow in critical limb ischemia through the growth of new vessels.

1. Introduction. Acute mesenteric ischemia (AMI) due to an embolism of the superior mesenteric artery (SMA) is a surgical emergency associated with a high mortality rate due to the difficulty in recognizing the condition before bowel infarction occurs. These thromboembolic events consist of multiple emboli in over twenty per cent of cases, which worsens the prognosis. We could find only one case of embolic episode in a lower limb following a SMA embolism that has been previously reported in the literature [1] . We hereby report a new case of AMI due to embolism of the SMA associated with lower limb acute ischemia.. 2. Case Presentation. A 62-year-old man, chronic smoker, was admitted to the emergency department complaining of history of abdominal pain since 2 days. Our patient was hemodynamically stable with temperature at 37.9˚C, and blood pressure was 120/80 mmHg. Abdominal examination was marked by diffuse abdominal tenderness, and limb examination showed bilateral toes ischemia (Figure 1). ...
INTRODUCTION. Mesenteric ischemia is a rare pathology among the general population, with an incidence of 0.09%-0.2% per patient/year.1, 2 In these patients it predominantly has an occlusive origin due to thrombosis formation on preexistent atherosclerotic lesions. 3 In the dialysis population it is more common, with reported incidence rates up to 1.9% per patient/year.4 In these patients, the ischemic condition may involve the small bowel and/or the colon, and it usually is non-occlusive. Events compromising the mesenteric blood flow upon an already altered circulation due to atherosclerosis-induced stenotic lesions may precipitate the development of mesenteric ischemia. The precipitating factors may be fast and excessive ultrafiltration during the dialysis sessions with the resulting arterial hypotension, or volume depletion due to other causes independent of dialysis such as diarrhea, vomiting, fever or acute states of low cardiac output.3, 5, 6 Mesenteric ischemia is a condition with high ...
Studies were designed to examine the effect of a selective endothelinA (ETA) receptor antagonist, BQ123, on severe postischemic acute renal failure (ARF) in Sprague-Dawley rats. Severe ARF was induced in uninephectomized, chronically instrumented rats by 45-min renal artery occlusion. BQ123 (0.1 mg/kg.min) or vehicle was infused intravenously for 3 h on the day after ischemia. Measurements before infusion (24 h control) showed a 98% decrease in glomerular filtration rate (GFR), increase in fractional excretion of sodium from 0.6 to 39%, and in plasma K+ from 4.3 to 6.5 mEq/liter. All vehicle-treated rats died in 4 d because of continuous deterioration of renal function, resulting in an increase of plasma K+ to fatal levels (, 8 mEq/liter). Infusion of BQ123 significantly improved survival rate (75%) by markedly improving tubular reabsorption of Na+ and moderately increasing GFR and K+ excretion. Plasma K+ returned to basal levels by the 5th d after ischemia. Improved tubular function was ...
TY - JOUR. T1 - Early activation of caspase-1 after retinal ischemia and reperfusion injury in mice. AU - Zheng, Guang Ying. AU - Zhang, Cheng. AU - Li, Zhi Gang. PY - 2004/5/1. Y1 - 2004/5/1. N2 - Background. Caspases are important in the signaling pathway of cellular apoptosis. Caspase-3 protein expression has been shown to increase and parallel to neuronal apoptosis in retinal ischemia injury. This study was to determine whether caspase-1 is involved in neuronal cell death or in retinal ischemia and reperfusion injury. Methods. In twenty-one adult mice, ischemia was induced by increasing the intraocular pressure. The animals were sacrificed at 1 hour, 3 hours, 6 hours, 1 day, 3 days and 7 days after reperfusion. Frozen sections were used for caspase-1 immunostaining and TUNEL labeling. Results. In normal retina, no caspase-1 positive cells were seen. One hour after ischemia, numerous positive cells were noted in the ganglion cell layer (GCL) and inner side of inner nuclear layer (INL). At 3 ...
