Abstract
A 79-year-old man presented with acute-onset coldness and severe pain in his left foot 4 hours prior. His foot (distal to the left Lisfranc joint) was pale and cold with slight motor and sensory deficits. Angiography demonstrated occlusion of the lateral plantar artery and plantar metatarsal arteries (PMAs). Angioplasty using balloons for each PMA and lateral plantar artery was conducted, but failed to achieve satisfactory blood flow. The foot condition subsequently worsened. A 22-gauge cannula was then inserted into the dorsalis pedis artery, and continuous local intra-arterial infusion of heparin, alprostadil, and nicorandil was administered. A marked reduction in the cyanotic areas of the foot was observed, with improved motor and sensory deficits post-continuous local intra-arterial infusion therapy. Follow-up angiography via the cannula on day 3 of hospitalization demonstrated significant flow improvement in the first to third PMAs. Foot salvage was achieved without tissue necrosis or amputation.

Abstract
BACKGROUND Although femoropopliteal-specific stents have durable patency, stent thrombosis (ST) may occur, which can lead to acute limb ischaemia (ALI). AIMS We aimed to investigate the clinical features and outcomes of ALI caused by femoropopliteal ST in patients with lower extremity artery disease. METHODS This multicentre retrospective study included 499 patients with ALI - of whom 108 patients had ALI caused by femoropopliteal ST (ST-ALI) and 391 patients had ALI caused by other aetiologies (de novo ALI) - who underwent treatment between September 2011 and March 2023. Clinical features and outcomes were compared between the two groups. The primary outcome measure was 12-month amputation-free survival; factors associated with amputation or death were investigated using multivariate Cox proportional hazards regression analysis. RESULTS Patients with ST-ALI were significantly more likely to exhibit conventional atherosclerotic risk factors, including diabetes mellitus (63% vs 26%) and haemodialysis (51% vs 10%) compared to patients with de novo ALI, whereas patients with de novo ALI were older (80 years vs 74 years) and more likely to have atrial fibrillation (49% vs 18%) than patients with ST-ALI. The 12-month amputation-free survival rate was significantly lower in the ST-ALI group than that in the de novo ALI group (51% vs 76%; p<0.001). Multivariate analysis revealed that ST-ALI, older age, haemodialysis, atrial fibrillation, the presence of a wound, peak C-reactive protein level, and non-ambulatory status all have an independent, positive association with death or major amputation. CONCLUSIONS The current study revealed that patients with ST-ALI had worse clinical outcomes than those with de novo ALI, highlighting the need to maximise ST prevention.

Abstract
Objectives To develop a novel and accurate nomogram to predict survival without amputation in patients with acute lower limb ischemia (ALLI) during the first year following endovascular therapy. Methods Patients with ALLI who underwent endovascular therapy in our department between January 2012 and September 2020 were screened and included in the research. The included patients were randomly divided into a training and validation cohorts, respectively. Univariate and multivariate analyses were used in the training cohort to identify independent risk factors for amputation-free survival (AFS). A nomogram was then developed according to the identified independent risk factors. The nomogram was then validated in the validation cohort. Results 415 Chinese patients with 417 affected limbs were included in this study. Among these patients, 311 patients were classified into the training cohort and 104 patients were assigned to the validation cohort. Most patients were men (n = 240) and the average age of patients was 71.43 (standard deviation 8.86) years old. After the univariate and multivariate analyses, advanced age (p < 0.001), history of smoking (p < 0.001), atrial fibrillation (p < 0.001), and insufficient outflow (p = 0.001) were revealed as independent risk factors for AFS during the first year. The nomogram yielded AUROC values of 0.912 (95 % confidence interval [CI]: 0.873-0.950) and 0.889 (95 % CI: 0.812-0.967) in the training and validation cohorts, respectively. Conclusion Advanced age, history of smoking, atrial fibrillation, and insufficient outflow were independent negative predictors for AFS in ALLI patients treated by endovascular therapy. The novel nomogram offered an accurate prediction of AFS in ALLI patients.

Abstract
OBJECTIVE Whether socioeconomic status (SES) is associated with health outcomes in patients with acute limb ischemia (ALI) is largely unknown. We aimed to determine whether SES is associated with worse presentations and outcomes for patients with ALI. METHODS We performed a retrospective medical record review of patients who presented with ALI between April 2016 and October 2020 at a single tertiary care center. SES was quantified using individual variables (median household income, level of education, and employment) and a composite endpoint, the neighborhood deprivation index (NDI). The NDI is a standardized and reproducible index that uses census tract data (higher number indicates lower SES status). The NDI summarizes 8 domains of socioeconomic deprivation. ALI severity was categorized using the Rutherford classification. The association between SES and the severity of ALI at presentation and between SES and other health outcomes were analyzed using bivariate analysis of variance, independent t test, and multivariate logistic regression. RESULTS During the study period, 278 patients were treated for ALI, of whom 211 had complete SES data available. The mean age was 64 years, 55% were men, and 57% were White. The Rutherford classification of disease severity was grade 1, 2a, 2b, and 3 for 6%, 54%, 32%, and 8% of patients, respectively. Patients with a low SES status per the NDI were more likely to have a history of peripheral arterial disease and chronic kidney disease at presentation. The ALI etiology (thrombotic vs embolic) was not associated with SES. No significant differences were seen between SES and the severity of ALI at presentation (p = 0.96) or the treatment modality (p = 0.80). No associations between SES and 30-day or 1-year mortality were observed (mean NDI, 0.15 vs 0.26, p = 0.58, and 0.20 vs 0.26, p = 0.71, respectively) or between SES and 30-day or 1-year limb loss (mean NDI, 0.06 vs 0.30, p = 0.18, and 0.1 vs 0.32, p = 0.17, respectively). Lower SES (higher NDI) was associated with increased 30-day readmission (mean NDI, 0.49 vs 0.15, p = 0.021). However, this association was not significant on multivariate analysis (odds ratio 1.4, 95% CI 0.9-2.1, p = 0.06). CONCLUSIONS SES was not associated with the severity of ALI at patient presentation. Although SES was associated with the presence of peripheral arterial disease and chronic kidney disease at presentation, SES was not a predictor of short-term or 1-year limb loss and mortality. Overall, ALI presentation and treatment outcomes were independent of SES.

Abstract
INTRODUCTION Acute limb ischemia is a rare but serious condition that carries with it a high rate of morbidity and mortality. OBJECTIVE This review highlights the pearls and pitfalls of acute limb ischemia, including presentation, diagnosis, and management in the emergency department (ED) based on current evidence. DISCUSSION Acute limb ischemia is defined as a sudden decrease in limb perfusion resulting in cessation of blood flow and nutrient and oxygen delivery to the tissues. This leads to cellular injury and necrosis, ultimately resulting in limb loss and potentially systemic symptoms with significant morbidity and mortality. There are several etiologies including native arterial thrombosis, arterial thrombosis after an intervention, arterial embolus, and arterial injury. Patients with acute limb ischemia most commonly present with severe pain and sensory changes in the initial stages, with prolonged ischemia resulting in weakness, sensory loss, and color changes to the affected limb. The emergency clinician should consult the vascular specialist as soon as ischemia is suspected, as the diagnosis should be based on the history and examination. Computed tomography angiography is the first line imaging modality, as it provides valuable information concerning the vasculature and surrounding tissues. Doppler ultrasound of the distal pulses may also be obtained to evaluate for arterial and venous flow. Once identified, management includes intravenous unfractionated heparin and vascular specialist consultation for revascularization. CONCLUSIONS An understanding of acute limb ischemia can assist emergency clinicians in diagnosing and managing this potentially deadly disease.

Abstract
Acute lower limb ischemia (ALI) is a common vascular emergency, requiring urgent revascularization by open or endovascular means. The aim of this retrospective study was to evaluate patient demographics, treatment and periprocedural variables affecting the outcome in ALI patients in a consecutive cohort in a tertiary referral center. Primary outcome events (POE) were 30-day (safety) and 180-day (efficacy) combined mortality and major amputation rates, respectively. Secondary outcomes were perioperative medical and surgical leg-related complications and the 5-year combined mortality and major amputation rate. Statistical analysis used descriptive and uni- and multivariable Cox regression analysis. In 985 patients (71 ± 9 years, 56% men) from 2004 to 2020, the 30-day and 180-day combined mortality and major amputation rates were 15% and 27%. Upon multivariable analysis, older age (30 d: aHR 1.17; 180 d: 1.27) and advanced Rutherford ischemia stage significantly worsened the safety and efficacy POE (30 d: TASC IIa aHR 3.29, TASC IIb aHR 3.93, TASC III aHR 7.79; 180 d: TASC IIa aHR 1.97, TASC IIb aHR 2.43, TASC III aHR 4.2), while endovascular treatment was associated with significant improved POE after 30 days (aHR 0.35) and 180 days (aHR 0.39), respectively. Looking at five consecutive patient quintiles, a significant increase in endovascular procedures especially in the last quintile could be observed (17.5% to 39.5%, p < 0.001). Simultaneously, the re-occlusion rate as well as the number of patients with any previous revascularization increased. In conclusion, despite a slightly increasing early re-occlusion rate, endovascular treatment might, if possible, be favorable in ALI treatment.

Abstract
BACKGROUND Pharmaco-mechanical thrombolysis (PMT) has emerged as a treatment option in patients with acute lower limb ischemia (ALI), especially Rutherford IIb (motor deficit) for rapid revascularization, but supportive data is scarce. The aim of the present study was to compare effect of thrombolysis, complications, and outcomes of PMT first versus catheter-directed thrombolysis (CDT) first in a large cohort of patients with ALI. BASIC PROCEDURES All endovascular thrombolytic/thrombectomy events in patients with ALI performed between January 1st 2009 and December 31st 2018 (n=347) were included. Successful thrombolysis/thrombectomy was defined as complete or partial lysis. Reasons for use of PMT was described. Complications such as major bleeding, distal embolization, and new onset of renal impairment, and major amputation and mortality at 30 days were compared between PMT (AngioJet™) first and CDT first groups in a multi-variable logistic regression model with adjustment for age, gender, atrial fibrillation, and Rutherford IIb. MAIN FINDINGS The most common reason for initial use of PMT was need of rapid revascularization, and the most common reason for use of PMT after CDT was insufficient effect of CDT. Presentation of Rutherford IIb ALI was more common in the PMT first group (36.2% vs 22.5%, respectively, p=0.027). Among 58 patients receiving PMT first, 36 (62.1%) were terminated within a single session of therapy without need of CDT. The median duration of thrombolysis was shorter (p<0.001) for the PMT first group (n=58) compared to the CDT first (n=289) group (4.0 hours vs 23.0 hours, respectively). There was no significant difference in amount of tissue plasminogen activator given, successful thrombolysis/thrombectomy (86.2% and 84.8%), major bleeding (15.5% and 18.7%), distal embolization (25.9% and 16.6%), major amputation or mortality at 30-day (13.8% and 7.7%) in the PMT first compared to the CDT first group, respectively. The proportion of new onset of renal impairment was higher in the PMT first compared to the CDT first group (10.3% versus 3.8%, respectively), and the increased odds (Odds ratio 3.57, 95% CI 1.22 - 10.41) was maintained in the adjusted model. In Rutherford IIb ALI, no difference in rate of successful thrombolysis/thrombectomy (76.2% and 73.8%), complications or 30-day outcomes was found between PMT first (n=21) and CDT (n=65) first group. CONCLUSION PMT first appears to be a good treatment alternative to CDT first in patients with ALI, including Rutherford IIb. The found renal function deterioration in the PMT first group needs to be evaluated in a prospective, preferably, randomized trial.

Abstract
BACKGROUND Acute peripheral arterial ischemia is a rapidly developing loss of perfusion, resulting in ischemic clinical manifestations. This study aimed to assess the incidence of cardiovascular mortality in patients with acute peripheral arterial ischemia and either atrial fibrillation (AF) or sinus rhythm (SR). METHODS This observational study involved patients with acute peripheral ischemia treated surgically. Patients were followed-up to assess cardiovascular mortality and its predictors. RESULTS The study group included 200 patients with acute peripheral arterial ischemia and either AF (n = 67) or SR (n = 133). No cardiovascular mortality differences between the AF and SR groups were observed. AF patients who died of cardiovascular causes had a higher prevalence of peripheral arterial disease (58.3% vs. 31.6%, p = 0.048) and hypercholesterolemia (31.2% vs. 5.3%, p = 0.028) than those who did not die of such causes. Patients with SR who died of cardiovascular causes more frequently had a GFR <60 mL/min/1.73 m2 (47.8% vs. 25.0%, p = 0.03) and were older than those with SR who did not die of such causes. The multivariable analysis shows that hyperlipidemia reduced the risk of cardiovascular mortality in patients with AF, whereas in patients with SR, an age of ≥75 years was the predisposing factor for such mortality. CONCLUSIONS Cardiovascular mortality of patients with acute ischemia did not differ between patients with AF and SR. Hyperlipidemia reduced the risk of cardiovascular mortality in patients with AF, whereas in patients with SR, an age of ≥75 years was a predisposing factor for such mortality.

Ma J, Chen J, Wang H, Lu D, Liang K. AhR regulates VEGF expression by promoting STAT1 transcriptional activity, thereby affecting endothelial angiogenesis in acute limb ischemia. Chem Biol Interact 2023; 369:110253. [PMID: 36347318 DOI: 10.1016/j.cbi.2022.110253] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/24/2022] [Revised: 10/07/2022] [Accepted: 11/02/2022] [Indexed: 11/06/2022]
Abstract
BACKGROUND Angiogenesis has great potential in the treatment of acute limb ischemia (ALI). Here, we aimed to investigate the effect and mechanism of Aryl hydrocarbon receptor (AhR) on angiogenesis in ALI. METHODS The ALI mouse model was constructed by femoral artery ligation, and the cell ischemia injury was induced by Hypoxia/serum deprivation. The laser doppler perfusion imaging was executed to detect the limb blood flow velocity. The tube formation assay was performed to evaluate angiogenesis. The cell viability was measured by 3-(45)-dimethylthiahiazo(-z-y1)-35-di-phenytetrazoliumromide. The cell migration was detected by wound healing assay. Hematoxylin-eosin, immunohistochemistry, immunofluorescence, dual-luciferase reporter gene assay, and Chromatin immunoprecipitation assay were conducted. RESULTS In ALI models, AhR expression was increased and translocated from cytoplasm to nucleus. Besides, necrosis and inflammatory infiltration were also increased in gastrocnemius tissues of model mice. In addition, AhR loss (LV-sh-AhR) promoted cell viability, angiogenesis, and migration, and also elevated the levels of vascular endothelial growth factor (VEGF), Tie2, and Ang2 in HUVEC models with Hypoxia/serum deprivation injury. Meanwhile, the interaction between AhR and signal transducer and activator of transcription 1 (STAT1), as well as STAT1 and VEGF, has also been confirmed. Co-transfection of LV-sh-AhR and LV-STAT1 suppressed cell viability, angiogenesis, and migration of injured HUVECs. Furthermore, injection of AAV2/9-shAhR in vivo also promoted angiogenesis, which was consistent with the in vitro experimental results. CONCLUSIONS In ALI models, activated AhR was translocated to the nucleus and down-regulated VEGF expression by promoting the transcriptional activity of STAT1, thereby inhibiting endothelial angiogenesis.

Abstract
Purpose Arterial stiffness and steno-occlusion of the lower-extremity can result from many vascular lesions, including acute thromboembolisms, soft plaques, calcified plaques, or inflammatory disease. Ultrasound (US) elastography measures the tissue deformation response to compression and displays tissue stiffness. This study aimed to evaluate the characteristics of arterial lesions in the lower extremities using US elastography. Materials and Methods We retrospectively analyzed the data of 20 patients who visited our institute for arterial disease treatment between May 2016 and November 2017. An US examination with B-mode and strain elastography (SE) was performed of four different lesion types at 45 sites: acute and subacute thromboembolisms, soft plaques, calcified plaques, and thromboangiitis obliterans lesions (TAOs). During SE, stress was externally applied by the operator using the transducer. Strain ratio (SR) was calculated as the fraction of the average strain in the reference area divided by the average strain in the lesion. The SR was compared among different lesion types, with the accompanying vein as the reference region of interest. Results The strain was highest in the soft plaques (0.63%±0.23%), followed by the TAOs (0.45%±0.11%), calcified plaques (0.44%±0.13%), and acute thromboembolisms (0.34%±0.23%), which were statistically significant (P=0.026). However, the mean SR was highest for the calcified plaques (2.33%±0.80%), followed by the TAOs (1.63%±0.40%), acute thromboembolisms (1.60%±0.48%), and soft plaques (1.51±0.39), and which were statistically significant (P=0.013). Conclusion Despite several limitations, vascular elastography may be useful for differentiating between lesion types in peripheral arterial disease.

Abstract
BACKGROUND Despite advances in endovascular techniques to treat acute limb ischemia (ALI), evaluation of clinical outcomes for revascularization remains challenging, especially the accurate quantification of post-endovascular limb perfusion. This study aimed to investigate the accuracy and value of 2D perfusion angiography to evaluate endovascular intervention for ALI. METHODS A total of 47 patients with ALI were retrospectively analyzed. The transcutaneous oxygen partial pressure (TcPO2) was obtained using laser Doppler blood perfusion monitoring. The ankle-brachial index (ABI) and angiographic images were obtained before and after endovascular intervention. iFlow imaging was used to obtain color-coded images. Regions of interest (ROIs) at the femoral head, knee joint, and ankle joint were selected to obtain the time to peak (TTP). The differences in the TTP between the knee and femoral head regions (TTP difference in the knee area) and between the ankle and knee regions (TTP difference in the ankle area) were observed. The TTP, ABI, and TcPO2 between the complete response (CR), partial response (PR), no response (NR), and amputation (AM) groups were compared. The correlation between TTP changes in the ankle area (ΔTTP) and changes in ABI (ΔABI)/changes in TcPO2 (ΔTcPO2) was analyzed. RESULTS There was a significant increase in both TcPO2 and ABI compared with the pre-intervention values (27.75 ± 5.32 vs 40.92 ± 4.62, and 0.35 ± 0.16 vs 0.79 ± 0.15, respectively, all p < 0.01). The post-intervention TTP differences in the knee areas (5.12 ± 2.45 s) and ankle areas (6.93 ± 4.37 s) were significantly faster than pre-intervention TTP differences (7.03 ± 2.57 s and 10.66 ± 4.07 s, respectively, all p < 0.05). The post-operative TTP in the ankle area, post-operative TTP difference in the ankle area, and ΔTTP in the AM group were higher than the values in the CR and PR groups. The ΔTTP demonstrated strong correlation with ΔABI (r = -0.722, p < 0.01) and ΔTcPO2 (r = -0.734, p < 0.01). CONCLUSIONS 2D perfusion angiography with enhanced visual and quantitative analysis exhibits great potential to evaluate the efficacy of endovascular intervention, and provides a quantitative and sensitive tool to evaluate post-endovascular limb perfusion for ALI patients.

Associations between SARS-CoV-2 infections and thrombotic complications necessitating surgical intervention: A systematic review. World J Methodol 2022; 12:476-487. [PMID: 36479312 PMCID: PMC9720352 DOI: 10.5662/wjm.v12.i6.476] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/15/2022] [Revised: 09/01/2022] [Accepted: 11/04/2022] [Indexed: 11/17/2022] Open
Abstract
BACKGROUND Several unique clinical features of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the cause of coronavirus disease 2019 (COVID-19) infection, have been identified and characterized. One such feature, mostly among patients with severe COVID-19 infection, has become known as COVID-19-induced coagulopathy. Surgical patients with a history of or active COVID-19 infection bear a significantly higher risk for postoperative thrombotic complications. These patients may require surgical intervention to treat severe thrombotic complications. Few studies have been carried out to better characterize this association. The purpose of this study was to perform a systematic review and meta-analysis of the literature on COVID-19 infections that led to thrombotic complications necessitating surgical intervention. We hypothesized that patients with recent or active COVID-19 infection would have high rates of thromboembolic complications both arterial and venous in origin. AIM To perform a systematic review and meta-analysis of the literature on COVID-19 infections that led to thrombotic complications necessitating surgical intervention. METHODS The current systematic review implemented an algorithmic approach to review all the currently available English medical literature on surgical interventions necessitated by COVID-19 thrombotic complications using the preferred reporting items for systematic reviews and meta-analysis principles. A comprehensive search of the medical literature in the "PubMed", "Scopus", "Google Scholar" top 100 results, and archives of Plastic and Reconstructive Surgery was performed using the key words "COVID-19" AND "surgery" AND "thromboembolism" AND "complication". The search string was generated and the records which were not specific about surgical interventions or thrombotic complications due to COVID-19 infection were excluded. Titles and abstracts were screened by two authors and full-text articles were assessed for eligibility and inclusion. Finally, results were further refined to focus on articles that focused on surgical interventions that were necessitated by COVID-19 thrombotic complications. RESULTS The database search resulted in the final inclusion of 22 retrospective studies, after application of the inclusion/exclusion criteria. Of the included studies, 17 were single case reports, 3 were case series and 2 were cross sectional cohort studies. All studies were retrospective in nature. Twelve of the reported studies were conducted in the United States of America, with the remaining studies originating from Italy, Turkey, Pakistan, France, Serbia, and Germany. All cases reported in our study were laboratory confirmed SARS-CoV-2 positive. A total of 70 cases involving surgical intervention were isolated from the 22 studies included in this review. CONCLUSION There is paucity of data describing the relationship between COVID-19 infection and thrombotic complications necessitating the need for surgical intervention. Intestinal ischemia and acute limb ischemia are amongst the most common thrombotic events due to COVID-19 that required operative management. An overall postoperative mortality of 30% was found in those who underwent operative procedures for thrombotic complications, with most deaths occurring in those with bowel ischemia. Physicians should be aware that despite thromboprophylaxis, severe thrombotic complications can still occur in this patient population, however, surgical intervention results in relatively low mortality apart from cases of ischemic bowel resection.

Abstract
Background: Numerous tools, including inflammatory biomarkers and lung injury severity scores, have been evaluated as predictors of thromboembolic events and the requirement for intensive therapy in COVID-19 patients. This study aims to verify the predictive role of inflammatory biomarkers [monocyte to lymphocyte ratio (MLR), neutrophil to lymphocyte ratio (NLR), platelet to lymphocyte ratio (PLR), systemic inflammatory index (SII), Systemic Inflammation Response Index (SIRI), and Aggregate Index of Systemic Inflammation (AISI)] and the CT Severity Score in acute limb ischemia (ALI) risk, intensive unit care (ICU) admission, and mortality in COVID-19 patients.; Methods: The present study was designed as an observational, analytical, retrospective cohort study and included all patients older than 18 years of age with a diagnosis of COVID-19 infection, confirmed through real time-polymerase chain reaction (RT-PCR), and admitted to the County Emergency Clinical Hospital of Targu-Mureș, Romania, and Modular Intensive Care Unit of UMFST “George Emil Palade” of Targu Mures, Romania between January 2020 and December 2021. Results: Non-Survivors and “ALI” patients were associated with higher incidence of cardiovascular disease [atrial fibrillation (AF) p = 0.0006 and p = 0.0001; peripheral arterial disease (PAD) p = 0.006 and p < 0.0001], and higher pulmonary parenchyma involvement (p < 0.0001). Multivariate analysis showed a high baseline value for MLR, NLR, PLR, SII, SIRI, AISI, and the CT Severity Score independent predictor of adverse outcomes for all recruited patients (all p < 0.0001). Moreover, the presence of AF and PAD was an independent predictor of ALI risk and mortality. Conclusions: According to our findings, higher MLR, NLR, PLR, SII, SIRI, AISI, and CT Severity Score values at admission strongly predict ALI risk, ICU admission, and mortality. Moreover, patients with AF and PAD had highly predicted ALI risk and mortality but no ICU admission.

Solitaire™ Stent Thrombectomy System in the Treatment of Acute Lower-Limb Ischemia: Comparisons in Safety and Effectiveness with Conventional Catheter-Directed Thrombolysis Therapy. BIOMED RESEARCH INTERNATIONAL 2022; 2022:6997221. [PMID: 36177056 PMCID: PMC9514949 DOI: 10.1155/2022/6997221] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 08/15/2022] [Revised: 08/31/2022] [Accepted: 09/07/2022] [Indexed: 11/29/2022]
Abstract
Objective The study aimed to investigate the safety and efficacy of the Solitaire™ AB Stent System (ev3 Inc., Plymouth, MN, USA) for the treatment of acute lower extremity ischemia (ALLI) compared with conventional catheter-directed thrombolytic therapy. Methods Retrospective analysis of patients with ALLI treated in the Department of Interventional Radiology at the First Hospital of Nanjing from January 2017 to April 2020 divided into a conventional (CDT) group (n = 106) and a percutaneous mechanical thrombectomy (PMT) group (n = 55) according to the procedure. PMT was performed using the Solitaire™ AB stent system. The combined clinical outcomes of mortality, major amputation, recurrent ischemia, and major morbidity were compared between the two groups. Results Of the 161 patients, 128 (79.5%) did not have a composite clinical outcome after 12 months of follow-up, namely, 78 CDT patients and 50 PMT patients, with significant differences in composite clinical outcome (26.4% vs. 9.1%, P = 0.010) and mortality (19.8% vs. 7.3%, P = 0.037) between them. Thrombolytic drug dose (19.34 ± 5.93 vs. 13.55 ± 6.54 mg, P < 0.001) and length of hospital stay (8.29 ± 3.91 vs. 5.49 ± 1.18 days, P = 0.003) were significantly lower in the PMT group. Conclusion PMT with the Solitaire™ AB Stent System is safer and more effective in treating patients with Rutherford stage I-IIB ALLI, with the advantage of rapid opening of obstructed vessels, shorter thrombolysis time, reduced thrombolytic dose, and improved blood flow to the infrapopliteal vessels.

Abstract
Acute Limb Ischemia (ALI) of the lower limb is defined as a sudden drop in arterial limb perfusion, which is a medical emergency requiring prompt intervention with high amputation and mortality rates in the absence of revascularization. This observational, analytical, and retrospective cohort study with longitudinal follow-up aimed to confirm the relevance of the preoperative inflammatory biomarkers neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) in predicting the 30-day poor prognosis of patients with Rutherford classification (RC) grades II and III ALI. The ROC analysis found a strong association of an NLR > 4.33 with all studied outcomes, while a PLR > 143.34 was associated with all studied outcomes, except the composite endpoint in all RC stages. Depending on the optimal cut-off value, the ROC analysis found a higher incidence of all adverse outcomes in all high NLR (>4.33) and high PLR (>143.34) groups. A multivariate analysis showed that a high baseline value for NLR and PLR was an independent predictor of amputation (OR:11.09; 95% CI: 5.48−22.42; p < 0.0001; and OR:8.97; 95% CI: 4.44−18.16; p < 0.0001), mortality (OR:22.24; 95% CI: 9.61−51.47; p < 0.0001; and OR:8.32; 95% CI: 3.90−17.73; p < 0.0001), and composite endpoint (OR:21.93; 95% CI: 7.91−60.79; p < 0.0001; and OR:9.98; 95% CI: 3.89−25.55; p < 0.0001), respectively. Furthermore, for all hospitalized patients, the RC grade III (OR:7.33; 95% CI: 3.73−14.26; p < 0.0001) was an independent predictor of amputation (OR:7.33; 95% CI: 3.73−14.26; p < 0.0001), mortality (OR:8.40; 95% CI: 4.08−17.31; p < 0.0001), and composite endpoint (OR: 10.70; 95% CI: 4.48−25.56; p < 0.0001), respectively. The NLR and PLR are excellent predictors of risks associated with ALI for primary and secondary prevention. Our study showed that increased pre-operative values for NLR and PLR are indicators of a poor outcome in patients with RC grades II and III ALI.

Abstract
BACKGROUND Whether pharmaco-mechanical thrombolysis (PMT) results in superior outcomes to catheter-directed thrombolysis (CDT) in treating thrombotic or embolic arterial occlusion of the lower limbs is unclear. METHODS We enrolled 94 patients with Rutherford class I-IIb due to thrombotic or embolic arterial occlusion in the lower limbs and who received emergency endovascular treatment. Baseline demographics, laboratory data, angiography and clinical outcomes were collected through chart reviews and fluoroscopic imaging. The procedural characteristics (thrombolytic drug dosage, treatment duration, and additional procedures), immediate angiographic outcomes (patency of calf vessels, and complete lysis), complications (major bleeding, and fasciotomy), and primary composite end-points (30-day mortality, amputation, and reocclusion) were compared between patients who received CDT versus PMT. RESULTS Compared with CDT, PMT was independently associated with lower total UK dosage (standardised coefficientβ= - 0.44; p < 0.01) and higher prevalence of complete lysis (odds ratio = 1.78, 95% confidence interval: 1.03 - 3.06; p = 0.04) after adjustments of covariates. The PMT group had significantly shorter treatment duration (23.00 [7.25 - 39.13] vs. 41.00 [27.00 - 52.50]; p < 0.01). No significant intergroup differences were observed for the primary composite end point (10.7% vs. 9.1%; p = 0.81), or prevalence of the major bleeding (9.1% vs. 0.0%; p = 0.10) despite the PMT group comprising patients with more.advanced chronic kidney disease and more diffuse thrombosis. CONCLUSIONS PMT with a Rotarex is a safe and effective strategy for treating thrombotic or embolic lower limb ischemia. It significantly reduced the thrombolytic drug dosage, and resulted in the complete lysis being more likely.

Abstract
BACKGROUND Acute limb ischaemia usually is caused by a blood clot blocking an artery or a bypass graft. Severe acute ischaemia will lead to irreversible damage to muscles and nerves if blood flow is not restored in a few hours. Once irreversible damage occurs, amputation will be necessary and the condition can be life-threatening. Infusion of clot-busting drugs (thrombolysis) is a useful tool in the management of acute limb ischaemia. Fibrinolytic drugs are used to disperse blood clots (thrombi) to clear arterial occlusion and restore blood flow. Thrombolysis is less invasive than surgery. A variety of techniques are used to deliver fibrinolytic agents. This is an update of a review first published in 2004. OBJECTIVES To compare the effects of infusion techniques during peripheral arterial thrombolysis for treatment of patients with acute limb ischaemia. SEARCH METHODS The Cochrane Vascular Information Specialist searched the Cochrane Vascular Specialised Register, CENTRAL, MEDLINE, Embase, and CINAHL databases and World Health Organization International Clinical Trials Registry Platform and ClinicalTrials.gov trials registries to 20 October 2020. We undertook reference checking to identify additional studies. SELECTION CRITERIA We included all randomised controlled trials (RCTs) comparing infusion techniques for fibrinolytic agents in the treatment of acute limb ischaemia. DATA COLLECTION AND ANALYSIS We used standard methodological procedures as recommended by Cochrane. We assessed the risk of bias in included trials using the Cochrane 'Risk of bias' tool. We evaluated certainty of evidence using GRADE. For dichotomous outcomes, we calculated the odds ratio (OR) with the corresponding 95% confidence interval (CI). We were not able to carry out meta-analyses due to clinical heterogeneity, so we have reported the results and performed the comparisons narratively. The main outcomes of interest were amputation-free survival or limb salvage, amputation, mortality, vessel patency, duration of thrombolysis, and complications such as cerebrovascular accident and major and minor bleeding. MAIN RESULTS Nine studies with a total of 671 participants are included in this update. Trials covered a variety of infusion techniques, dosage regimens, and adjunctive agents. We grouped trials according to types of techniques assessed (e.g. intravenous and intra-arterial delivery of the agent, 'high-' and 'low-dose' regimens of the agent, continuous infusion and 'forced infusion' of the agent, use of adjunctive antiplatelet agents). We assessed the certainty of evidence as very low to low due to the limited power of individual studies to deliver clinically relevant results, small and heterogeneous study populations, use of different inclusion criteria by each study in terms of severity and duration of ischaemia, considerably different outcome measures between trials, and use of different fibrinolytic agents. This heterogeneity prevented pooling of data in meta-analyses. No regimen has been shown to confer benefit in terms of amputation-free survival (at 30 days), amputation, or death. For vessel patency, complete success was more likely with intra-arterial (IA) than with intravenous (IV) infusion (odds ratio (OR) 13.22, 95% confidence interval (CI) 2.79 to 62.67; 1 study, 40 participants; low-certainty evidence); radiological failure may be more likely with IV infusion (OR 0.02, 95% CI 0.00 to 0.38; 1 study, 40 participants; low-certainty evidence). Due to the small numbers involved in each arm and design differences between arms, it is not possible to conclude whether any technique offered any advantage over another. None of the treatment strategies clearly affected complications such as cerebrovascular accident or major bleeding requiring surgery or blood transfusion. Minor bleeding complications were more frequent in systemic (intravenous) therapy compared to intra-arterial infusion (OR 0.03, 95% CI 0.00 to 0.56; 1 study, 40 participants), and in high-dose compared to low-dose therapy (OR 0.11, 95% CI 0.01 to 0.96; 1 study, 63 participants). Limited evidence from individual trials appears to indicate that high-dose and forced-infusion regimens reduce the duration of thrombolysis. In one trial, the median duration of infusion was 4 hours (range 0.25 to 46) for the high-dose group and 20 hours (range 2 to 46) for the low-dose group. In a second trial, treatment using pulse spray was continued for a median of 120 minutes (range 40 to 310) compared with low-dose infusion for a median of 25 hours (range 2 to 60). In a third trial, the median duration of therapy was reduced with pulse spray at 195 minutes (range 90 to 1260 minutes) compared to continuous infusion at 1390 minutes (range 300 to 2400 minutes). However, none of the studies individually showed improvement in limb salvage at 30 days nor benefit for the amputation rate related to the technique of drug delivery. Similarly, no studies reported a clear difference in occurrence of cerebrovascular accident or major bleeding. Although 'high-dose' and 'forced-infusion' techniques achieved vessel patency in less time than 'low-dose' infusion, more minor bleeding complications may be associated (OR 0.11, 95% CI 0.01 to 0.96; 1 study, 72 participants; and OR 0.48, 95% CI 0.17 to 1.32; 1 study, 121 participants, respectively). Use of adjunctive platelet glycoprotein IIb/IIIa antagonists did not improve outcomes, and results were limited by inclusion of participants with non-limb-threatening ischaemia. AUTHORS' CONCLUSIONS There is insufficient evidence to show that any thrombolytic regimen provides a benefit over any other in terms of amputation-free survival, amputation, or 30-day mortality. The rate of CVA or major bleeding requiring surgery or blood transfusion did not clearly differ between regimens but may occur more frequently in high dose and IV regimens. This evidence was limited and of very low certainty. Minor bleeding may be more common with high-dose and IV regimens. In this context, thrombolysis may be an acceptable therapy for patients with marginally threatened limbs (Rutherford grade IIa) compared with surgery. Caution is advised for patients who do not have limb-threatening ischaemia (Rutherford grade I) because of risks of major haemorrhage, cerebrovascular accident, and death from thrombolysis.

Abstract
BACKGROUND Acute limb ischaemia (ALI) is a limb and life-threatening condition with significant morbidity. There are currently no consensus recommendations for the investigative practices to determine the aetiology of ALI presenting without a known aetiology. We undertook a detailed analysis of all investigations performed to identify an underlying precipitant in those with unexplained ALI and formulated a suggested diagnostic algorithm for the evaluation of unexplained ALI. METHODS ALI cases presenting to a tertiary referral centre over a 3-year period were reviewed, and known aetiologies, and investigations undertaken to determine the underlying aetiology of unexplained ALI were obtained. RESULTS Unexplained ALI was found in 27 of 222 patients (12%), of which 21 (78%) had a cause for ALI established after further investigations. Six patients had no cause identified despite extensive work-up. Most patients with unexplained ALI had a cardioembolic source identified as the underlying cause (62%), and this included atrial fibrillation, infective endocarditis, cardiac myxoma and intra-cardiac thrombus. Other causes of unexplained ALI were detected by computed tomography (CT) imaging and included newly diagnosed significant atherosclerotic disease (19%), embolism from isolated proximal large vessel thrombus (10%) and metastatic malignancy (10%). There were no cases attributed to inherited thrombophilias, myeloproliferative neoplasms or anti-phospholipid syndrome. CONCLUSION Among patients with unexplained ALI, the majority had a cardioembolic source highlighting the importance of comprehensive cardiac investigations. A subset of patients had alternative causes identified on CT imaging. These data support the use of a collaborative and integrative diagnostic algorithm in the evaluation of unexplained ALI.

Abstract
BACKGROUND The purpose of our study is to assess the short-term technical success and the safety of the Indigo System in a series of patients undergoing vacuum-assisted catheter direct thrombus aspiration (IS-CDTA) for acute lower limb ischemia (ALLI) and to evaluate which parameters may affect the outcome. METHODS All procedures using the IS-CDTA for ALLI, performed in a single-centre Interventional Radiology Unit from February 2016 to March 2020, were retrospectively analysed. Technical success was defined as the achievement of nearly-complete or complete revascularization (TIPI grade 2/3) and considered as a good outcome. Variables potentially correlated with the IS-CDTA outcome were analysed. RESULTS 33 procedures were performed in 29 patients. Mean age was 69 years old (range 47 - 88), 24 males (83%) and 5 females (18%). The technical success was 70%. Catheter-directed thrombolysis following IS-CDTA was performed in 23 cases and the overall technical success increased from 70% to 90%, afterwards. The median time between symptoms insurgency and IS-CDTA was significantly shorter in patients with good outcome (10 hours; IQR 2.75-48) compared to those with poor outcome (168 hours; IQR 36-336) (P = 0.003). No statistically significant differences were found between the two groups regarding ATK vs. BTK (P = 0.34), native vessel vs. graft (P = 0.25), occlusion nature P = 0.28) or Rutherford score (P = 0.80). CONCLUSION IS-CDTA is a valid option for a rapid and percutaneous treatment of ALLI. Our experience indicates that the time elapsing from the symptoms insurgency and the endovascular procedure is the best positive predictor of the outcome.

Abstract
BACKGROUND A steadily growing number of primary lower extremity arterial reconstructions is inevitably followed by the need to perform repeat interventions. Shunt reocclusion may become a cause of return of ischaemia to the initial level, may significantly increase the degree of limb-threatening chronic ischaemia, as well as lead to the development of an acute condition requiring urgent corrective measures to be taken. A reoperation currently continues to remain the standard of treatment. Despite advances in modern resuscitation, the postoperative mortality rate in such patients reaches 20%. AIM This study was aimed at assessing feasibility of hybrid technologies in acute thrombosis after reconstructive operations on lower-limb arteries. PATIENTS AND METHODS We retrospectively analysed the results of treatment of 66 consecutive patients urgently admitted to the City Clinical Hospital named after S.S. Yudin from 2015 to 2020 with acute lower limb ischaemia caused by acute occlusion of the zone of primary vascular reconstructions previously performed at other medical facilities. Depending on the method of surgical treatment, the patients were divided into two groups. The Study group included 20 patients subjected to open surgical interventions followed by angiographic control and using one or other type of X-ray-endovascular treatment. Endovascular interventions were performed for more than 70% stenoses in the major arteries and zone of the previously performed operation. The Comparison group comprised 46 patients treated without endovascular technologies. They were subjected to thrombectomy from the vascular construction with/without reconstructive-restorative operations. RESULTS Seventeen (85%) of the 20 Study group patients were operated on in a stagewise manner, with the first stage consisting of an open intervention - thrombectomy and reconstruction followed by angiographic control and roentgenendovascular treatment. The remaining three (15%) patients underwent simultaneous interventions. In the postoperative period, limb amputations were performed in ten (22%) Comparison group patients and in one (5%) Study group patient (p=0.049). There were three (7%) lethal outcomes in the Comparison group, with none in the Study group. CONCLUSION A combination of open and endovascular interventions in patients with shunt occlusion after vascular reconstructions makes it possible to reveal the cause of shunt occlusion, as well as to remove multilevel lesions, minimizing surgical wound and contributing to reducing the amputation rate.

Abstract
BACKGROUND Coronavirus disease 2019 (COVID-19) infection can cause alterations in the coagulation mechanism conditioning thrombotic phenomena such as acute limb ischemia (ALI) as the only manifestation of the infection. The aim of the study was to describe clinical and surgical characteristics of a group of patients infected with severe acute respiratory syndrome coronavirus 2 who presented ALI in the context of the COVID-19 pandemic at Lima, Peru. METHODS A multicenter, observational, and retrospective study was performed in six general hospitals, from March to July 2020. The variables considered were the pathological history and associated habits, laboratory tests, the severity of COVID-19 infection and ALI, the anatomic location of the lesion, treatment, evolution, and discharge conditions. RESULTS Thirty patients with ALI infected with COVID-19 were evaluated. Their mean age was 60 ± 15 years, the condition being more frequent in men (76.6%). The main comorbidities were arterial hypertension (33.3%), obesity (33.3%), and diabetes mellitus 2 (26.6%). There were 23.3% asymptomatic patients, and their only manifestation was ALI. Rutherford IIA and IIB stage included 93.2% of patients. The most frequent location of the thrombosis was the lower limbs (73.3% vs. 26.6%). Thrombectomy was performed in 76.6% of the patients, and amputation (primary and secondary) was performed in 30% of the patients. The mortality rate was 23.3%, all of it because of acute respiratory distress syndrome. CONCLUSIONS ALI is a vascular pathology associated with embolic and thrombotic processes. COVID-19 infection can cause severe alterations in coagulation mechanisms, leading some patients to present severe acute arterial complications such as thrombosis, as the only associated manifestation. We report a younger cohort than those described in other studies and with a high frequency of amputations despite adequate surgical treatment.

Abstract
Management of acute limb ischemia (ALI) due to occlusions in popliteal and infrapopliteal arteries remains a challenge. Open surgical methods and even the novel percutaneous mechanical thrombectomy devices have not shown satisfactory results in these small arteries. The aim of this prospective study was to assess the safety and efficacy of catheter-directed thrombolysis (CDT) in this type of ALI with distal occlusion. Between April 2017 and June 2019, 22 patients with ALI secondary to popliteal or infrapopliteal occlusion were enrolled in the study. Patients with thrombosis, embolism, and thrombosed bypass graft were included; all belong to category I or IIa of Rutherford's classification. Technical success, limb salvage, complications, and mortality were evaluated at short- and long-term follow-up. Technical success was achieved in 81.8%, while 36.4% of patients needed additional balloon angioplasty, major amputation in 13.6%, minor bleeding in 18.2%, and no major hemorrhage. Limb salvage at 30 days and 1 year was 86.4% and 72.7%, respectively. At 1 year, primary patency was 63.6% and mortality was 9.1%. Catheter directed thrombolysis is a safe and highly effective treatment modality for popliteal or infrapopliteal acute limb ischemia unless contraindicated.

Abstract
Lifelong anticoagulation with warfarin or alternative vitamin K antagonist is the standard anticoagulant treatment for thrombotic antiphospholipid syndrome. Anticoagulant-refractory thrombotic antiphospholipid syndrome can be broadly defined as breakthrough thrombosis while on standard oral anticoagulation treatment and its management is a major challenge given the serious nature of the thrombotic disease observed, which has become refractory to oral anticoagulation. The factors (genetic and cellular) that cause anticoagulant-refractory thrombotic antiphospholipid syndrome are now better understood. However, efforts to use this greater understanding have not yet transformed the capacity to treat it successfully in many patients. In this Viewpoint, we review the factors that are likely to be contributing to the cause of this syndrome and consider how they might be modified or inhibited. We also discuss management, including general strategies to minimise thrombotic risk, intensification of anticoagulation, addition of an antiplatelet agent, adjunctive treatment for thrombosis, immunomodulatory therapy, complement inhibition, vascular options, and future potential therapeutic targets.

Abstract
BACKGROUND Peripheral artery disease (PAD) is the most underdiagnosed, underestimated and undertreated of the atherosclerotic vascular diseases despite its poor prognosis. There may be racial or contextual differences in the Asia-Pacific region as to epidemiology, availability of diagnostic and therapeutic modalities, and even patient treatment response. The Asian Pacific Society of Atherosclerosis and Vascular Diseases (APSAVD) thus coordinated the development of an Asia-Pacific Consensus Statement (APCS) on the Management of PAD. OBJECTIVES The APSAVD aimed to accomplish the following: 1) determine the applicability of the 2016 AHA/ACC guidelines on the Management of Patients with Lower Extremity Peripheral Artery Disease to the Asia-Pacific region; 2) review Asia-Pacific literature; and 3) increase the awareness of PAD. METHODOLOGY A Steering Committee was organized to oversee development of the APCS, appoint a Technical Working Group (TWG) and Consensus Panel (CP). The TWG appraised the relevance of the 2016 AHA/ACC PAD Guideline and proposed recommendations which were reviewed by the CP using a modified Delphi technique. RESULTS A total of 91 recommendations were generated covering history and physical examination, diagnosis, and treatment of PAD-3 new recommendations, 31 adaptations and 57 adopted statements. This Asia-Pacific Consensus Statement on the Management of PAD constitutes the first for the Asia-Pacific Region. It is intended for use by health practitioners involved in preventing, diagnosing and treating patients with PAD and ultimately the patients and their families themselves.

Abstract
Acute limb ischemia (ALI) is a vascular emergency associated with a high risk for limb loss and death. Most cases result from in situ thrombosis in patients with preexisting peripheral arterial disease or those who have undergone vascular procedures including stenting and bypass grafts. The other common source is cardioembolic. The incidence has decreased in recent times due to better anticoagulation strategies. Patients with suspected ALI should be evaluated promptly by a vascular specialist and consideration should be given for transfer to a higher level of care if such expertise is not available locally. Initial assessment should focus on staging severity of ischemic injury and potential for limb salvage. Neurological deficits can occur early and are an important poor prognostic sign. Duplex ultrasound and computed tomography angiography help plan intervention in patients with a still-viable limb and prompt catheter-based angiography is mandated in patients with an immediately threatened limb. Further investigations need to be pursued to differentiate embolic from thrombotic cause for acute occlusion as this can change management. Options include intravascular interventions, surgical bypass, or a hybrid approach. In this article, the authors discuss the common etiologies, clinical evaluation, and management of patients presenting with acute limb ischemia.

Abstract
Abstract
Background: Blood viscosity is a strong predictor of cardiovascular events. However, the relationship between blood viscosity and acute arterial occlusion (AAO) has not been studied adequately so far.
Objectives: The aim of the present study was to assess the relationship between whole blood viscosity (WBV) and AAO.
Material and methods: The study included 93 patients who were diagnosed with AAO between January 2017 and September 2019, and 90 age- and sex-matched healthy controls. WBV was assessed using a validated calculation formula derived from hematocrit and total plasma protein levels, both as a low (LSR) and a high (HSR) shear rate.
Results: There were no significant differences between the two groups in regards to the baseline characteristics, with the exception of smoking and LDL cholesterol levels. Subjects with AAO presented significantly higher WBV values both at LSR (32.2 ± 5.0 vs. 26.6 ± 5.0, p <0.001) and HSR (6.2 ± 0.3 vs. 5.7 ± 0.3, p <0.001). The ROC analysis revealed a cut-off value of 27.4 for WBV at LSR (sensitivity 66%, specificity 64%, AUC = 0.770, p <0.001) and a cut-off value of 5.29 in case of HSR (sensitivity 69%, specificity 74%, AUC = 0.801, p <0.001) for predicting AAO. Multivariate analysis, both LSR (OR 3.33, 95% CI: 1.20–9.43, p = 0.006) and HSR (p = 0.020, OR: 1.70, 95% CI: 1.020–1.123) were independent predictors of AAO.
Conclusions: This study demonstrated that WBV levels at both HSR and LSR are significantly higher in the AAO group than in the control subjects, indicating that an increased WBV may be associated with the development of AAO.

Abstract
Summary: Background: To evaluate trends in frequency, mortality and treatment for non-traumatic vascular emergencies (VE) in the US. Methods: VE in the Nationwide Inpatient Sample (2005–2014) were identified. ICD-9 CM diagnosis and procedures codes captured six common VE. Results: 228,210,504 emergency admissions with 317,396 procedures for VE were estimated. Mean age was 67.8 years and were primarily men (56.1 %; p < 0.0001). The commonest VE was Acute Limb Ischemia (ALI) (82.4 %) followed by ruptured AAA (10.8 %) and Acute Mesenteric Ischemia (4.71 %). VE increased from 132.8 per 100,000 admissions in 2005 to 153.6 in 2014 (p < 0.001), with mortality decrease for all VE (13.8 % vs. 9.1 %; p < 0.0001). Length of stay decreased (median 8 vs. 7 days; p < 0.0001) but cost of care increased (median $ 25,443 vs. $ 29,353; p < 0.0001). Endovascular treatment increased overall for VE from 23.7 % in 2005 to 37.2 % in 2014 (p < 0.0001). Hospital mortality for VE decreased overall, except ruptured thoracoabdominal aortic aneurysm with mortality decrease with endovascular treatment (34.3 vs. 11.1; p = 0.04) and mortality increase with open treatment (44.7 vs. 47.6; p = 0.06). ALI overall mortality decreased from 8.1 % to 5.7 % (p < 0.0001) due to reduced open surgical mortality from 9.6 % to 7.4 % (p < 0.0001); endovascular mortality did not improve over time (4.0 % vs. 3.4 %; p = 0.45). Hospital mortality also increased for endovascular treatment of ruptured thoracic aortic aneurysm (rTAA) from 14.9 % to 27.4 % (p = 0.0003) during this period. Conclusions: VE frequency increased with a decrease in overall mortality over time. Overall hospital stay has decreased but with an increase in the cost of care. Open surgical mortality for VE has also decreased overall, suggesting perioperative care improvements, with the exception of ruptured thoracoabdominal aortic aneurysm. Endovascular utilization for VE has significantly increased; associated with lower mortality for most VE, although an increase in hospital mortality after endovascular repair of rTAA was seen. This may be due to an increased implementation of endovascular repair for patients not previously eligible for surgery due to high risk. We recommend careful selection of patients for rTAA treatment as mortality has increased despite endovascular therapy and at an increased cost of care.

Effect of Intra-operative Intra-arterial Thrombolysis on Long Term Clinical Outcomes in Patients with Acute Popliteal Artery Aneurysm Thrombosis. Eur J Vasc Endovasc Surg 2020; 59:255-264. [PMID: 31917126 DOI: 10.1016/j.ejvs.2019.10.013] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/12/2019] [Revised: 09/30/2019] [Accepted: 10/18/2019] [Indexed: 01/06/2023]
Abstract
OBJECTIVE Acute lower limb ischaemia (ALI) as a result of popliteal artery aneurysm (PAA) thrombosis represents a significant problem. The aim of this study was to investigate outcome of intra-operative intra-arterial thrombolysis in the treatment of acute ischaemia due to PAA thrombosis in terms of major adverse limb events (MALE), overall survival, and intrahospital complications, especially those associated with bleeding. METHODS A total of 156 patients with Rutherford grade IIa and IIb acute ischaemia resulting from PAA thrombosis were admitted between 1 January 2011 and 1 January 2017. The patients were divided into two groups, those who underwent additional treatment with intra-operative intra-arterial thrombolysis (20 patients), and those who did not (136 patients). By using covariables from baseline and angiographic characteristics, a propensity score was calculated for each patient. Each patient who underwent intra-operative thrombolysis was matched to four patients from the non-thrombolysis group. Thus, comparable patient cohorts (20 in the thrombolysis and 80 in the non-thrombolysis group) were identified for further analysis. The primary end point was MALE and the secondary endpoint all cause mortality. RESULTS After a median follow up of 55 months, the estimated MALE rate was significantly lower in the thrombolysis group (30% vs. 65%, chi square = 10.86, p < .001, log rank test). Also, patients in the thrombolysis group had a significantly lower mortality rate (20% vs. 42.65%, chi square = 3.65, p = .05, log rank test). The thrombolysis group had wound/haematoma related interventions performed more commonly (25% in thrombolysis vs 8%, in non-thrombolysis group), but the difference was not significant (p=.013). There were no cases of major (intracranial and gastrointestinal) bleeding in either group. CONCLUSION The data suggest that intra-operative thrombolysis in the treatment of selected patients with ALI due to PAA thrombosis has long term MALE and overall survival benefits, without a significant risk of major, life threatening bleeding complications.

Abstract
Objective: To examine the medium- to long-term outcomes of acute limb ischemia (ALI), which are unclear at present. Methods: We analyzed 93 consecutive limbs in 77 patients with ALI between January 2005 and December 2015 treated at our vascular center. We categorized the cases into four groups according to etiology (embolism, thrombosis, graft thrombosis, and dissection groups) to assess survival, limb salvage, and freedom from re-intervention rates. Results: The mean age at onset was 72±15 years. The median follow-up length was 2.90 years. The Rutherford categories I, IIa, IIb, and III included 1, 38, 51, and 3 cases, respectively. Thromboembolectomy was performed in all patients in the embolism and thrombosis groups. In addition, endovascular treatment was performed in 25 (37.3%) patients, especially in the thrombosis group (81.3%). A major amputation could not be avoided in 10 patients. The 5-year limb salvage rates for categories IIa and IIb were 97.1% and 83.1%, respectively. The 5-year freedom from re-intervention rate was 89.2%. The survival rates at 1, 3, and 5 years were 87.9%, 75.2%, and 60.6%, respectively. Conclusion: The 5-year survival rates of patients with ALI were equivalent to those with chronic limb threatening ischemia (CLTI). The intervention and long-term outcomes were distinguishable according to etiology.

Abstract
Peripheral arterial disease (PAD) is frequently underdiagnosed and undertreated. This review identifies specific subgroups within older adults more likely to develop PAD, and describes methods to diagnose PAD and provide evidence in support of systematic referral to cardiac rehabilitation programs to enhance successful comprehensive management. Clear evidence and guidelines support the routine use of supervised exercise therapy to improve function, reduce risk of cardiovascular morbidity and mortality, and enhance the success of endovascular interventions.

Abstract
OBJECTIVE The objective of this study was to assess factors predisposing patients to recurrent acute lower limb ischemia (RALLI). METHODS Acute lower limb ischemia patients treated with catheter-directed thrombolysis (CDT) at Tampere University Hospital and Turku University Hospital between March 2002 and December 2015 were included. The patients' baseline demographics, comorbidities, and other characteristics were assessed retrospectively. Significant factors revealed by univariable analysis were tested in a multivariable model for associations with RALLI. A patency analysis was performed, and the risks of reocclusion were identified. The limb salvage rates after reocclusion were evaluated. RESULTS Altogether, 303 consecutive patients with a mean age of 71 years (standard deviation, 11.8 years) were included. Of them, 159 (52.5%) were men. A total of 164 (54.1%) native arterial and 139 (45.9%) bypass graft occlusions were initially treated with CDT. On completion of CDT, 204 additional endovascular or conventional surgical procedures on 203 patients were performed to obtain adequate distal perfusion. During a median follow-up of 40 months (interquartile range, 69 months), 40 (24.4%) cases of RALLI occurred in native arteries and 90 (64.7%) in bypass graft patients (P < .001). In native arteries, the absence of appropriate anticoagulant and antiplatelet medication was independently associated with the development of acute reocclusions (hazard ratio, 6.51) in the Cox multivariable regression analysis. The patency rates were 86.6%, 72.2%, and 68.0% at 1 year, 5 years, and 9 years, respectively. In bypass grafts, worsened tibial runoff (crural index III: hazard ratio, 2.40) was independently associated with RALLI. The respective patency rates were 60.5%, 34.0%, and 29.2% for synthetic conduits and 30.8%, 20.5%, and 13.7% for autologous vein grafts at 1 year, 5 years, and 9 years. Altogether, 38 (29.2%) major amputations were performed on patients with reocclusions. Patients with synthetic conduits demonstrated superior limb salvage rates after reocclusion in comparison to native arteries or vein grafts (P = .025). CONCLUSIONS Appropriate post-thrombolytic antiplatelet or anticoagulant treatment after native arterial events is of great importance, but additional data are needed to improve treatment algorithms. Adequate outflow in bypass graft patients is crucial. Patients with prosthetic bypass grafts have superior limb salvage rates after reocclusion.

Abstract
This review presents an update on the diagnosis and management of acute limb ischemia (ALI), a severe condition associated with high mortality and amputation rates. A comprehensive spectrum of ALI etiology is presented, with highlights on embolism and in situ thrombosis. The steps for emergency diagnosis are described, emphasizing the role of clinical data and imaging, mainly duplex ultrasound, CT angiography and digital substraction angiography. The different therapeutic techniques are presented, ranging from pharmacological (thrombolysis) to interventional (thromboaspiration, mechanical thrombectomy, and stent implantation) techniques to established surgical revascularization (Fogarty thrombembolectomy, by-pass, endarterectomy, patch angioplasty or combinations) and minor or major amputation of necessity. Postprocedural management, reperfusion injury, compartment syndrome and long-term treatment are also updated.

Abstract
The role of cilostazol after endovascular therapy (EVT) of peripheral artery disease (PAD) remains unclear. We conducted a meta-analysis for all studies reporting the outcomes of cilostazol after EVT of PAD from January 2000 through November 2018 with the outcomes of interest including primary patency, major adverse limb events (MALE), target lesion revascularization (TLR), and major amputation. We included eight studies (three randomized controlled trials (RCTs) and five observational studies) with a total of 3846 patients (4713 lesions). During a mean follow-up duration of 12.5 ± 5 months, the use of cilostazol was associated with higher primary patency (OR 2.28, 95% CI (1.77, 2.94), p < 0.001, I2 = 24%), lower risk of TLR (OR 0.37, 95% CI (0.26, 0.52), p < 0.001, I2 = 0%), and lower risk of major amputation (OR 0.15, 95% CI (0.04, 0.62), p = 0.008, I2 = 0%). The use of cilostazol in RCTs was associated with significantly higher odds of primary patency compared with observational studies (OR 3.37 vs 2.28, p-interaction = 0.03). After further subgroup analysis, cilostazol remained associated with higher primary patency regardless of the use of anticoagulants (warfarin) (p-interaction = 0.49). We conclude that the use of cilostazol after EVT of femoropopliteal and iliac lesions is associated with improved primary patency and lower risk of major amputation and TLR. The favorable impact of cilostazol is independent of the use of warfarin. PROSPERO identifier: CRD42018092715.

Abstract
Acute limb ischemia (ALI), a subclass of critical limb ischemia, is a medical emergency. The cause of ALI is usually thrombotic or embolic in nature, and the specific etiology often dictates the appropriate therapy. While the diagnosis is a clinical with common presenting symptoms, advances in ultrasound, computed tomography, and magnetic resonance technology have impacted the diagnosis and subsequent therapy. In ALI, the time to revascularization is critical and computed tomography angiography (CTA) provides a highly sensitive and specific technique for rapidly identifying occlusions and precisely defining vascular anatomy prior to interventions. In patients with significant renal disease, magnetic resonance angiography with or without contrast provides effective alternatives at the expense of imaging time. Treatment can include a variety of endovascular or surgical interventions, including thromboembolectomy, angioplasty, or bypass. Proper evaluation of the etiology of the ischemia, affected vasculature, and medical history is critical to select appropriate treatment and improve patient outcomes. Here, we examine the presentation, evaluation, and treatment of ALI and the role of CTA in diagnosis and therapy.

Abstract
Objective Acute limb ischemia is a common vascular emergency requiring immediate intervention. Thrombolysis has been widely utilized for acute limb ischemia; the purpose of this study is to analyze contemporary trends, outcomes and complications of thrombolysis for acute limb ischemia. Methods Patients were identified from the Nationwide Inpatient Sample (2003–2013) using ICD-9. Patients undergoing emergency thrombolysis for acute limb ischemia were evaluated. Three groups were analyzed: thrombolysis alone, thrombolysis and endovascular procedure (T+ENDO), and failed thrombolysis requiring open surgery (T+OPEN). Results A total of 162,240 patients with acute limb ischemia were estimated: 33,615 patients (20.7%) underwent thrombolysis as the initial treatment. Mean age was 66.2 ± 34.9 years with 54% male. The utilization of thrombolysis increased significantly during the study period (16.8–24.2%, p < 0.0001). The most common group was thrombolysis and endovascular procedure (40.7%), followed by thrombolysis alone (34.1%), and T+OPEN (25.2%). Thrombolysis and endovascular procedure increased significantly over time (31.6–47.8%, p < 0.0001) whereas thrombolysis alone and T+OPEN significantly decreased (39.6–28.6% and 28.7–23.6%, respectively, p < 0.0001). Overall mortality was 4.9%; thrombolysis and endovascular procedure compared to thrombolysis alone and T-OPEN had a lower mortality rate (3.2% vs. 6.1% and 5.9%, p < 0001). The overall stroke rate was 1.9%; thrombolysis alone had the highest stroke rate (3.0%, p < 0.0001) with thrombolysis and endovascular procedure the lowest (1.2%) and T+OPEN 1.7%. The highest amputation rate was T+OPEN (11.6%, p < 0.001) compared to thrombolysis and endovascular procedure (5.1%) and thrombolysis alone (5.3%). T+OPEN had the highest incidence of cardiac (5.5%), respiratory (7.3%) and renal complications (12.5%), pneumonia (4.0%), and fasciotomy (16.8%) (all p < 0.0001). Conclusion Thrombolysis remains an effective treatment for acute limb ischemia with increased utilization over time. There was a significant increase in thrombolysis and endovascular procedure leading to improved outcomes. Thrombolysis alone carried the highest mortality and stroke rate, with T+OPEN associated with the highest amputation and complications. Although thrombolysis is effective, 25% of patients required an open procedure suggesting that patient selection for thrombolysis first instead of open surgery continues to be a clinical challenge.

Abstract
Background Consensus is lacking regarding intervention for patients with acute lower limb ischaemia (ALI). The aim was to study amputation‐free survival in patients treated for ALI by either primary open or endovascular revascularization. Methods The Swedish Vascular Registry (Swedvasc) was combined with the Population Registry and National Patient Registry to determine follow‐up on mortality and amputation rates. Revascularization techniques were compared by propensity score matching 1 : 1. Results Of 9736 patients who underwent open surgery and 6493 who had endovascular treatment between 1994 and 2014, 3365 remained in each group after propensity score matching. Results are from the matched cohort only. Mean age of the patients was 74·7 years; 47·5 per cent were women and mean follow‐up was 4·3 years. At 30‐day follow‐up, the endovascular group had better patency (83·0 versus 78·6 per cent; P < 0·001). Amputation rates were similar at 30 days (7·0 per cent in the endovascular group versus 8·2 per cent in the open group; P = 0·113) and at 1 year (13·8 versus 14·8 per cent; P = 0·320). The mortality rate was lower after endovascular treatment, at 30 days (6·7 versus 11·1 per cent; P < 0·001) and after 1 year (20·2 versus 28·6 per cent; P < 0·001). Accordingly, endovascular treatment had better amputation‐free survival at 30 days (87·5 versus 82·1 per cent; P < 0·001) and 1 year (69·9 versus 61·1 per cent; P < 0·001). The number needed to treat to prevent one death within the first year was 12 with an endovascular compared with an open approach. Five years after surgery, endovascular treatment still had improved survival (HR 0·78, 99 per cent c.i. 0·70 to 0·86) but the difference between the treatment groups occurred mainly in the first year. Conclusion Primary endovascular treatment for ALI appeared to reduce mortality compared with open surgery, without any difference in the risk of amputation. Endovascular may save lives

Abstract
PURPOSE To evaluate the efficacy and safety of thrombectomy using myocardial biopsy forceps for the treatment of acute limb ischemia (ALI). MATERIALS AND METHODS A retrospective review of 11 ALI patients (12 affected limbs, 18 affected vessels) who underwent thrombectomy using biopsy forceps between November 2011 and April 2016 was performed. Of the 12 affected limbs, 2 limbs had stent thrombosis, 1 limb had thrombotic occlusion at a de novo stenosis site, and 9 limbs had embolic ALI. Biopsy forceps were used for angiographically limited arterial flow that persisted after the use of an aspiration catheter and conventional balloon angioplasty. The general technique for use of the biopsy forceps included advancement in parallel to a guidewire to the thrombus site, grasping of the thrombus with the forceps, and confirmation of grasping the thrombus with injection of a contrast medium prior to thrombus extraction. RESULTS Partial or total retrieval of the thrombus was angiographically confirmed in 12 of the 18 affected vessels, with restoration of normal blood flow in 11 vessels. Unsuccessful results in the remaining 6 affected vessels appeared to be due to friction at the aortoiliac bifurcation caused by the contralateral approach, small vessel size, or curvature of the anterior tibial artery. None of the 18 treated vessels had any complications such as dissection or perforation of the target vessel wall and distal emboli. None of the surviving patients required major or minor amputation. CONCLUSIONS Thrombectomy using biopsy forceps is a feasible technique for removal of an arterial thrombus in patients with ALI.

Abstract
BACKGROUND The treatment of acute limb ischemia (ALI) has barely changed over the last years. However, the progressive implementation of anticoagulants, antiplatelet agents or statins within the population might have modified the profile and prognosis of patients suffering an ALI. The aim of this study was to evaluate the current results of the management of ALI secondary to a native artery occlusion. METHODS Retrospective study of 220 consecutive patients (mean age 78 years; 49% male) was conducted between 2007 and 2015. ALI secondary to trauma or grafts/stents occlusions were excluded. Statistical analysis was performed with logistic regression. RESULTS A total of 141 cases (64.1%) were attributed to embolism and 79 (35.9%) to acute arterial thrombosis. Peripheral neuro-ischemic impairment occurred in 135 patients (61.4%), being severe in 42 (19.1%). ALI treatment included anticoagulation (n = 27; 12.3%), regional fibrinolysis (n = 2; 1%), embolectomy/thrombectomy (n = 129; 58.6%), angioplasty/stenting (n = 8; 3.6%), bypass (n = 47; 21.3%) or direct major limb amputation (n = 7; 3.2%). Limb salvage and survival rates at 30/90 days were 95%/95% and 82.3%/74.1%, respectively. Independent risk factors for major amputation were diabetes, severe neuro-ischemic impairment, acute arterial thrombosis and treatment delay >1 day after vascular consultation. In addition, age, chronic peripheral arterial disease, any neuro-ischemic impairment and a hospitalization for any other reason simultaneous to the ALI were independently associated with mortality. CONCLUSIONS Regardless of excellent limb salvage rates, patients currently suffering from an ALI are, when compared to previous studies, older than before and with an increased rate of mortality. Risk factors do not appear to be modifiable once the ALI appears so prevention strategies should be aimed to avoid the episode.

Abstract
Peripheral arterial disease (PAD) affects 15% of the Australian population and is a powerful and serious predictor of cardiovascular mortality yet continues to be under-recognised and undertreated. Diagnosis is simple and management is centred upon symptom relief and risk minimisation. While novel and specialised therapies play a role, the bulk of management is approachable and feasible. In this review, we cover the epidemiology, risk factors, associated conditions, classification, and natural history of PAD. We then discuss current diagnostic and therapeutic options as well as emerging therapies for this common condition.

Abstract
The presence of diabetes mellitus is rarely addressed in acute lower limb ischaemia (ALLI). The aim of this study was to evaluate the outcome of local intra-arterial thrombolysis for ALLI in patients with diabetes mellitus (DM). Outcome of all thrombolytic events performed in an endovascular first-strategy centre during a 13-year period between 2001 and 2013 in patients with ALLI were followed to January 2017. A propensity score adjusted analysis was performed to evaluate results in patients with (n = 83) versus without (n = 316) DM. Patients with DM were younger (p = 0.001), more often women (p = 0.014), more often had renal insufficiency (p = 0.041), foot ulcers (p < 0.001), and thrombosis (p = 0.032) than the patients without DM. At presentation, patients with DM had a lower degree of ischemia judged by the Rutherford classification, compared to those without DM (p = 0.023). None of the 83 diabetic patients had a popliteal artery aneurysm, compared to 25 (7.9%) of the 316 patients without DM (p = 0.008). The amount of tPA administered to patients with DM was higher than to patients without DM (p = 0.03). In the propensity score adjusted analysis, patients with DM had a higher rate of major amputation at 1 (OR 2.52; 95% CI 1.22–5.20) and 3 years (OR 2.52; 95% CI 1.26–5.04), and a lower amputation-free survival at 3 years (OR 0.46; 95% CI 0.25–0.85), than those without DM. Patients with DM presenting with ALLI differ in clinical characteristics, presentation, and aetiology compared to patients with DM, and have a higher rate of major amputation and lower amputation-free survival rate after intra-arterial thrombolysis.

Abstract
OBJECTIVES Acute lower limb ischaemia (ALLI) is a potentially fatal, limb threatening medical emergency. Early treatment is essential for a good outcome. The aim was to describe the early chain of care in ALLI focusing on lead times and emergency management in order to identify weak links for improvement. METHODS This was a retrospective, descriptive case study. This study analysed the medical records of all patients with a main discharge diagnosis of ALLI between January 2009 and December 2014. Predetermined emergency care data on lead times, diagnosis recognition, presenting symptoms, emergency care treatment and outcome were collected for patients who were transported by the Emergency Medical Service (EMS) and those who were not. RESULTS In total, 552 medical records were audited of which 195 patients fulfilled the inclusion criteria and were analysed. Among them were 117 (60%) transported by the EMS. The median time from symptom onset to revascularisation was 23 (interquartile range [IQR] 10-55; EMS transported) and 93 (IQR 42-152, not EMS transported) hours (p < .01). The time from symptom onset to arrival in hospital was 5 (IQR 2-26; EMS transported) and 48 (IQR 6-108; not EMS transported) hours. After arrival in hospital, the median time to first doctor evaluation was 51 (IQR 28-90; EMS transported) and 80 (IQR 44-169; not EMS transported) minutes, p = .01. Low molecular weight heparin (LMWH) was given to 72% of patients in the emergency department (ED) and a multivariate analysis showed that the use of LMWH was associated with a more favourable outcome. CONCLUSIONS Both the time spent in the ED and the time from the onset of symptoms to revascularisation were considerably longer than optimal. Time delays in the early treatment chain can mainly be attributed to "patient delay" and a considerable time spent in hospital before revascularisation. The use of LMWH as an integral part of ED management was associated with a better outcome.

Abstract
Acute limb ischemia is a vascular emergency, threatening the viability of the affected limb and requiring immediate recognition and treatment. Even with revascularization of the affected extremity, acute limb ischemia is associated with significant morbidity and mortality resulting in up to a 15% risk of amputation during the initial hospitalization and a 1 in 5 risk of mortality within 1 year of the index event. This review summarizes the current management of acute limb ischemia. Understanding the diagnosis and therapeutic options will aid clinicians in treating these critically ill patients.
