Aims: Near-infrared spectroscopy (NIRS) is able to quantify cholesterol within coronary arteries by the lipid core burden index (LCBI). We studied the prognostic value of NIRS-derived LCBI in patients with coronary artery disease (CAD) for adverse cardiac outcome during long-term follow-up. Methods and results: During 2009-2013, NIRS was performed in a non-culprit artery of 275 patients undergoing coronary angiography for acute coronary syndrome (ACS) or stable angina...

Background The objective of ischemic stroke (IS) treatment is to achieve revascularization in cerebral arteries to restore blood flow. However, there is no available method to extract arterial flow data from clinical CTA images. We developed 3D Stroke Arterial Flow Estimation (SAFE), which provides blood flow data throughout the Circle of Willis based on 3D CTA and allows comparison of arterial flow distribution in the brain. Methods We implemented a newly developed 3D vascular reconstruction algorithm for clinical stroke CTA images...

Alongside the remarkable progress in therapeutic strategies destined to patients with coronary artery disease (CAD), a growing number of patients who suffer from severe and diffuse CAD not amenable for revascularization, continue to experience severe debilitating angina despite optimal medical therapy. The Coronary Sinus (CS) Reducer has emerged as a novel therapeutic strategy for patients with refractory angina pectoris. The Reducer is a stainless steel, balloon-expandable, hourglass shaped device implanted percutaneously through the right internal jugular vein in the coronary sinus...

Heinz Winkler, Peter Haiden
The treatment of chronic bone and joint infections is characterized by obstinate persistency of the causing microorganisms and resulting long term disability to patients, associated with remarkable costs for the health care system. Difficulties derive from biofilm formed on dead bone and eventual implants, with resistance against immunological defences and antimicrobial substances. Biofilm embedded bacteria require up to 1000 times the antibiotic concentration of planktonic bacteria for elimination. Systemic antibiotic treatment alone cannot provide the concentrations required and surgical intervention is always prerequisite for potentially providing a cure...

BACKGROUND: There is a substantial reduction in cardiovascular related morbidity and mortality in the general population attributed to improved treatment of cardiac risk factors and disease, the same magnitude of benefit has not been observed in those with diabetes mellitus. The aim of the present study was to evaluate factors associated with the cardiac outcome at 1 year after coronary angiogram in patients with type 2 diabetes mellitus and to compare the outcomes with nondiabetics. METHODS: A retrospective cohort study was carried out in subjects who underwent coronary angiogram for an evaluation of CAD, with follow-up data available for period of 12 months...

Selection of patients with atherosclerotic carotid stenosis for revascularization is mainly based on the degree of luminal narrowing of the carotid artery. However, identification of other features of plaque apart from the degree of stenosis could enable better selection for intervention if they are also associated with the occurrence of stroke. Before these risk factors can possibly play a role in treatment decisions, their prognostic value needs to be proven. The purpose of this narrative review is to summarize current knowledge regarding the risk factors for stroke in patients with carotid stenosis, how they can be determined, and to what extent they predict stroke, based on recent literature...

Spontaneous coronary artery dissection (SCAD) is becoming widely recognized as an important cause of myocardial infarction, particularly in younger women. Tendency toward conservative management has been primarily based on observational data. Intervention is recommended when coronary blood flow is compromised and high risk features such as left main involvement, ongoing ischemia, or hemodynamic or electrical instability are present. Unlike the atherosclerotic process where the superiority of stenting compared with plain old balloon angioplasty has been established in the acute setting, randomized studies for revascularization strategies for spontaneous coronary dissection are currently lacking...

OBJECTIVE: Surgical site infection (SSI) after open lower extremity bypass (LEB) is a serious complication leading to an increased rate of graft failure, hospital readmission, and health care costs. This study sought to identify predictors of SSI after LEB for arterial occlusive disease and also potential modifiable factors to improve outcomes. METHODS: Data from a statewide cardiovascular consortium of 35 hospitals were used to obtain demographic, procedural, and hospital risk factors for patients undergoing elective or urgent open LEB between January 2012 and June 2015...

OBJECTIVE: Concern over perioperative and long-term durability of lower extremity revascularizations among active smokers is a frequent deterrent for vascular surgeons to perform elective lower extremity revascularization. In this study, we examined perioperative outcomes of lower extremity endovascular (LEE) revascularization and open lower extremity bypass (LEB) in active smokers with intermittent claudication (IC) and critical limb ischemia (CLI). METHODS: Active smokers undergoing LEE or LEB from 2011 to 2014 were identified in the American College of Surgeons (ACS) National Surgical Quality Improvement Program (NSQIP) targeted vascular data set...

Achieving a precise diagnosis of the pulp status of traumatized teeth is difficult. The time to interfere through endodontic treatment for these teeth is greatly dependent on the doctor's experience. A 24-year-old male patient suffered a traumatic injury to tooth #9 that resulted in an apical root horizontal fracture 3 days before he came to the hospital. The injured tooth showed no response to pulp sensitivity testing at the first visit and was discolored 1 week later. Tooth #9 was immobilized to its adjacent teeth for 4 weeks by a composite splint...

It is not uncommon that patients with peripheral arterial disease (PAD) need to undergo a lower limb amputation, with or without previous revascularization attempts. Despite that, the patient's experience of the amputation has been scarcely studied. The aim of this qualitative study was to describe the patient's experience of amputation due to PAD. Thirteen interviews were conducted with vascular patients who had undergone a lower limb amputation at tibia, knee, or femoral level. Data were analyzed with content analysis...

INTRODUCTION: Despite improvements in revascularization, major amputation remains a significant part of the case-mix in vascular surgical units. These patients tend to be elderly with complex pathology, resulting in poor outcomes and longer lengths of stay (LOS). AIM: This series review provides a description of the patient complexities and outcomes in an Australian cohort undergoing major lower limb amputation for peripheral arterial disease. METHOD: Medical records coded for major amputation between July 2012 and June 2013 in an Australian government funded, tertiary hospital were retrospectively reviewed and descriptively analyzed...

INTRODUCTION: Randomized and nonrandomized clinical trials have tried to assess whether or not TMR patients experience an increase in myocardial perfusion. However there have been inconsistencies reported in the literature due to the use of different nuclear imaging modalities to test this metric. The primary purpose of this meta-analysis was to determine whether SPECT, MUGA and PET scans demonstrate changes in myocardial perfusion between lased and non-lased subjects and whether laser type affects myocardial perfusion...

OBJECTIVES: Using intravascular ultrasound (IVUS), the authors compared outcomes by observed wire position (intraplaque vs. subintimal) achieved during successful chronic total occlusion (CTO) lesion treatment. BACKGROUND: Recent successes in CTO percutaneous coronary intervention (PCI) have used both intraluminal and subintimal wire tracking to improve procedural success. IVUS may be used to determine the course of wire tracking after crossing a CTO. METHODS: From March 2014 to March 2016, data were collected into a single-center database from 219 patients undergoing CTO PCI with concomitant IVUS imaging...
