Diabetes AND Chronic Total Occlusion

INTRODUCTION: Lower extremity angiography is one of the most prevalent vascular procedures performed, generally via the contralateral common femoral artery. The use of retrograde pedal artery access to perform angiography has long been reserved as a "bail-out" technique to help cross chronic total occlusions that were not amenable from an antegrade approach. Recently, there has been reports and discussion involving increased utilization of pedal access for primary revascularization. The purpose of this study is to describe the outcomes of pedal access as a primary approach and to propose a novel evaluation of distal perfusion changes associated with interventions using direct pressure measurements...

The 355 nm Auryon laser has been shown to be effective and safe in treating various morphology lesions in the femoropopliteal arteries. There are limited data on the Auryon laser in treating below the knee (BTK) arteries in patients with chronic limb threatening ischemia (CLTI). We present the 30-day efficacy and safety findings from the ongoing Auryon BTK study. Patients with CLTI were prospectively enrolled in the Auryon BTK study between March 2022 and February 2023 in 4 US centers after obtaining informed consent...

BACKGROUND: Although the 1-year clinical outcomes of fluoropolymer-based drug-eluting stents (FP-DES) were favorable for the treatment of real-world femoropopliteal lesions in symptomatic peripheral artery disease (PAD), their performance beyond 1 year remained unknown. The current study determined the 3-year clinical course of FP-DES implantation for real-world femoropopliteal lesions. METHODS: This multicenter, prospective, observational study evaluated 1204 limbs (chronic limb-threatening ischemia, 34...

OBJECTIVES: This pilot study assessed the 12-month angiographic and clinical outcomes of self-apposing (SA) stents in patients undergoing chronic total occlusion (CTO) percutaneous coronary intervention (PCI). BACKGROUND: Self-apposing (SA) stents may decrease incomplete strut apposition and stent strut coverage that are common after CTO PCI. METHODS: We compared 20 patients who underwent CTO PCI using SA drug-eluting stents (DESs) with 20 matched control patients who underwent CTO PCI using balloon-expandable (BE)-DESs...

BACKGROUND: Lower extremity peripheral artery disease (PAD) is the third most common clinical manifestation of atherosclerosis after coronary artery disease and stroke. Despite successful endovascular treatment (EVT), mortality and morbidity rates still remain higher in patients with PAD. Naples prognostic score (NPS) is a novel scoring system, reflects the patient's nutritional and immunological statuses as well as systemic inflammatory responses. In this study, we aimed to investigate the relationship between NPS and long-term outcomes in patients with PAD...

BACKGROUND: To investigate the correlation between triglyceride glucose index (TyG) and collateral circulation in patients with chronic total occlusion (CTO) of coronary arteries in different glucose metabolic states. METHODS: A total of 681 patients who underwent coronary angiography between January 2020 and December 2021 to determine the presence of CTO lesions in at least one major coronary artery were retrospectively included in this study. Patients were categorized into a group with poor collateral circulation formation (Rentrop grade 0-1, n = 205) and a group with good collateral circulation formation (Rentrop grade 2-3, n = 476) according to the Rentrop scale...

OBJECTIVE: To investigate the association between circulating secretoneurin (SN) and angiographic coronary collateralization in stable angina patients with chronic coronary total occlusion (CTO). METHODS: SN concentrations in serum were measured in 641 stable angina patients with CTO by radioimmunoassay. The status of coronary collaterals from the contra-lateral vessel was visually estimated using the Rentrop grading system, and was categorized into poor (grade 0 or 1) or good (grade 2 or 3) collateralization...

BACKGROUND: Atherosclerosis is a progressive disease characterized by the build-up of lipids and connective tissue in the large arteries. Some patients experience chronic total occlusion (CTO). Inflammation plays a key role in the development and complications of atherosclerosis. Neutrophil-to-lymphocyte ratio (NLR) is a marker of systemic inflammation associated with the development of acute coronary syndrome (ACS). We aimed to assess the relationship between NLR and CTO in ACS patients with ST elevated myocardial infarction (STEMI) in Indonesia...

INTRODUCTION AND OBJECTIVES: Coronary chronic total occlusions (CTO) are relatively common findings in patients with type 2 diabetes mellitus (T2DM). Despite this, the indication for percutaneous revascularization (PCI) and its clinical benefit in these patients remains controversial. METHODS: A single center retrospective cohort study with prospectively collected outcomes was carried out with CTO patients submitted to PCI between 2019-2020. Patients were divided in two groups regarding previous T2DM diagnosis (T2DM and non-T2DM)...

BACKGROUND: Fibrinogen is a potential risk factor for the prognosis of CAD and is associated with the complexity of CAD. There is limited research specifically investigating the predictive role of fibrinogen in determining the severity of CAD among patients with T2DM, as well as its impact on the prognosis following PCI. METHODS: The study included 675 T2DM patients who underwent PCI at the Third People's Hospital of Chengdu between April 27, 2018, and February 5, 2021, with 540 of them remaining after exclusions...

SUMMARY: Calciphylaxis is a rare disorder characterised by the development of painful necrotic skin lesions. Occlusion of cutaneous arterioles due to ectopic calcification leads to potentially life-threatening widespread skin loss. Most cases occur in patients with chronic renal disease, which leads to dysregulation of calcium and phosphate homeostasis. Only a handful of case reports exist describing calciphylaxis occurring in patients without chronic renal disease but with hypoparathyroidism...

BACKGROUND: Covid-19 has impacted the lives of individuals worldwide especially those with chronic illnesses. Children with type 1 diabetes (T1DM) are at risk of glycemic deterioration during the Covid-19 pandemic. However, some studies reported glycemic improvement in these children during the pandemic. AIM: To assess the impact of Covid-19 on glycemic control and acute complications among children with T1DM on insulin pump in Egypt. METHODOLOGY: Forty-two children with T1DM on insulin pump for at least 1 year were assessed during the period from June 2020 to May 2021 for insulin requirements, insulin-pump problems, frequency of diabetic-ketoacidosis (DKA), hypoglycemia and HbA1C...

BACKGROUND: To evaluate the midterm clinical efficacy of paclitaxel drug-coated balloons (DCBs) in the treatment of femoral artery TransAtlantic Inter-Society Consensus (TASC) grades C/D lesions. METHODS: The clinical data of 73 cases with TASC grades C/D lesions of femoral artery treated with paclitaxel DCBs at the Department of Vascular Surgery, the First Hospital of Fujian Medical University from August 2016 to January 2020 were retrospectively analyzed.

BACKGROUND: Triglyceride-glucose index (TyG) has been widely used to predict cardiovascular outcomes. However, it remains unclear whether TyG holds prognostic significance for patients with coronary chronic total occlusions (CTO). Thus, our study aimed to evaluate the predictive accuracy and prognostic value of TyG in individuals who underwent successful percutaneous coronary intervention (PCI) for CTO. METHODS: A total of 331 consecutive patients with ≥ 1 successful CTO-PCI were included...

BACKGROUND: Thoracofemoral bypass has been applied mostly secondary to previous procedures in the treatment of aortoiliac occlusive disease. However, its application as an initial treatment is less common, and long-term outcomes remain uncertain. The aim of this analysis was to review the 16-year experience and long-term outcomes of 31 consecutive patients who underwent thoracofemoral bypass as the primary procedure. METHODS: All patients who underwent thoracofemoral bypass for severe aortoiliac occlusive disease between 2005 and 2021 were retrospectively analyzed...

PURPOSE: To investigate the impact of optimal procedural techniques on the mid-term patency of fluoropolymer-based drug-eluting stent (FP-DES) in femoropopliteal artery. METHODS AND METHODS: This retrospective study included 200 femoropopliteal lesions (chronic limb-threatening ischemia, 59%; chronic total occlusion, 41%) in 173 patients (male, 66%; diabetes mellitus, 62%; hemodialysis, 40%) with lower extremity arterial disease undergoing intravascular ultrasound (IVUS)-guided endovascular therapy with FP-DES between January 2016 and July 2021...

AIM: The aim of the current study sought to investigate the angiographic patterns of restenosis after drug-coated balloon (DCB) angioplasty for femoropopliteal (FP) lesions and which repeat endovascular therapy (EVT) for DCB restenosis would provide more freedom from recurrent restenosis. METHODS: This retrospective multicenter study included 119 limbs (chronic limb-threatening ischemia [CLTI]: 55%, lesion length: 136.9 ± 89.6 mm, chronic total occlusion: 25%) of 95 patients (diabetes mellitus: 70%, hemodialysis: 56%) who were diagnosed with DCB restenosis between January 2018 and December 2019...

BACKGROUND: Chronic total coronary occlusion is among the most complex coronary artery diseases. Elevated homocysteine is a risk factor for coronary artery diseases. However, few studies have assessed the relationship between homocysteine and chronic total coronary occlusion. METHODS: 1295 individuals from Southwest China were enrolled in the study. Chronic total coronary occlusion was defined as complete occlusion of coronary artery for more than three months. Homocysteine was divided into quartiles according to its level...

Patients who undergo percutaneous coronary intervention (PCI) of chronic total occlusions (CTO) are at a high risk for both periprocedural and post-procedural adverse events. Whether gender-differences in outcomes exist after PCI of CTO remain unclear. Therefore, we sought to investigate gender-based differences in outcomes after CTO-PCI. All patients who underwent elective CTO intervention from January 2012 to December 2017 at The Mount Sinai Hospital (New York, New York) were included. The primary end point of interest was major adverse cardiac events defined as the composite of death, myocardial infarction, and target vessel revascularization at 1 year of follow-up...
