Revascularization Therapy

Intracerebral hemorrhage (ICH) secondary to intravenous and intraarterial revascularization strategies for emergent treatment of acute ischemic stroke is associated with high mortality. ICH from systemic thrombolysis typically occurs within the first 24–36 hours of treatment initiation and is characterized by rapid hematoma development and growth. Pathophysiological mechanisms of revascularization therapy-induced ICH are complex and involve a combination of several distinct processes, including the direct effect of thrombolytic agents, disruption of the blood-brain barrier secondary to ischemia, and direct vessel damage from wire and microcatheter manipulations during endovascular procedures. Several definitions of ICH secondary to thrombolysis currently exist, depending on clinical or radiological characteristics used. Multiple studies have investigated clinical and laboratory risk factors associated with higher rates of ICH in this setting. Early ischemic changes seen on noncontrast CT scanning are strongly associated with higher rates of hemorrhage. Modern imaging techniques, particularly CT perfusion, provide rapid assessment of hemodynamic parameters of the brain. Specific patterns of CT perfusion maps can help identify patients who are likely to benefit from revascularization or to develop hemorrhagic complications. There are no established guidelines that describe management of revascularization therapy–induced ICH, and great variability in treatment protocols currently exist. General principles that apply to the management of spontaneous ICH might not be as effective for revascularization therapy–induced ICH. In this article, the authors review current knowledge of risk factors and radiological predictors of ICH secondary to stroke revascularization techniques and analyze medical and surgical management strategies for ICH in this setting.

Abstract Acute ischemic stroke (AIS) has a high risk of recurrence, particularly in the early stage. The purpose of this study was to assess the frequency and risk factors of in-hospital recurrence in patients with AIS in China. A retrospective analysis was performed of all of the patients with new-onset AIS who were hospitalized in the past three years. Recurrence was defined as a new stroke event, with an interval between the primary and recurrent events greater than 24 hours; other potential causes of neurological deterioration were excluded. The risk factors for recurrence were analyzed using univariate and logistic regression analyses. A total of 1,021 patients were included in this study with a median length of stay of 14 days (interquartile range,11–18). In-hospital recurrence occurred in 58 cases (5.68%), primarily during the first five days of hospitalization. In-hospital recurrence significantly prolonged the hospital stay (P < 0.001), and the in-hospital mortality was also significantly increased (P = 0.006). The independent risk factors for in-hospital recurrence included large artery atherosclerosis, urinary or respiratory infection and abnormal blood glucose, whereas recurrence was less likely to occur in the patients with aphasia. Our study showed that the patients with AIS had a high rate of in-hospital recurrence, and the recurrence mainly occurred in the first five days of the hospital stay. In-hospital recurrence resulted in a prolonged hospital stay and a higher in-hospital mortality rate.

Abstract Background Presentation with massive systemic embolization as the initial manifestation of occult malignancy is infrequent. The standard management of cancer-related arterial thromboembolism has not yet been established. Case presentation We described a case of Trousseau’s syndrome resulting in acute ischemic stroke concomitant with multiple embolizations in the spleen and kidney during oral administration of dabigatran for pulmonary embolism preceding the diagnosis of a malignant tumor. A cancer-related hypercoagulable state was suspected because the patient was admitted to the neurology department due to acute ischemic stroke with three territory infarcts on diffusion-weighted imaging (DWI) in the absence of identifiable conventional risk factors and brain vessel narrowing. The patient was subsequently diagnosed with epidermal growth factor receptor (EGFR) mutation–positive non-small-cell lung cancer (NSCLC) (stage IV) with pleural metastasis. Administration of low-molecular-weight heparin followed by long-term dabigatran under effective cancer therapy comprising gefitinib and subsequent chemotherapy did not cause stroke relapse during the 1-year follow-up. Conclusions This case suggests that cancer-related hypercoagulability should be considered an important etiology for stroke patients who develop unexplained disseminated acute cerebral infarction without conventional stroke risk factors, especially concomitant with multiple organ embolization. Novel oral anticoagulants may be an alternative therapy for the long-term management of cancer-related arterial thromboembolism under effective cancer therapy.

Background: There is limited recent population-based data of trends in acute ischemic stroke (AIS) hospitalization rates among young adults (YA). Rising prevalence of stroke risk factors may increase stroke rates in YA. We hypothesized that 1) stroke hospitalizations and mortality among YA are increasing over time (2000-2011), 2) besides traditional stroke risk factors, non-traditional factors are associated with stroke in YA, 3) stroke hospitalization among YA is associated with higher mortality, length of stay (LOS), and cost. Methods: In the Nationwide Inpatient Sample database (years 2000-2011), adult hospitalizations for AIS and concurrent diagnoses were identified by ICD-9-CM codes; the analytic cohort constituted all AIS hospitalizations. We performed weighted analysis using chi-square, t-test, and Jonckheere trend test. Multivariable survey regression models evaluated interactions between age group (18-45 vs. >45 years) and traditional and non-traditional risk factors, with outcomes including mortality, LOS, and cost. Models were adjusted for race, sex, Charlson’s Comorbidity Index, primary payer, location and teaching status of hospital, and admission day. Results: Among 5220960 AIS hospitalizations, 231858 (4.4%) were YA. On trend analysis, proportion of YA amongst AIS increased from 3.6% in 2000 to 4.7% in 2011 (p<0.0001) but mortality in YA decreased from 3.7% in 2000 to 2.6% in 2011, compared to 7.1% in 2000 to 4.6% in 2011 (p<0.0001) among older adults. Non-traditional, especially behavioral, risk factors were more common among YA, and LOS and cost were higher (Table). Conclusion: There was a trend for higher proportion of YA among AIS hospitalizations, though there was a decreasing mortality trend over 10 years. Behavioral risk factors were more common among YA, and there was an increased length of stay and cost. AIS in YA may require different preventive approaches compared to AIS among older adults.

Introduction: In patients with acute stroke, part of the acute management entails identifying the risk factors; modifiable or non modifiable. Early recognition of these factors is essential for optimizing therapeutic procedures, especially those with a known effective treatment. In this sense, Sleep Disordered Breathing (SDB) has also been suggested as a modifiable and independent risk factor for stroke as defined by international guidelines and some studies have demonstrated that patients with stroke and particularly Obstructive Sleep Apnea (OSA) have an increased risk of death or new vascular events. Pathogenesis of ischemic stroke in SDB is probably related to worsening of existing cardiovascular risk factors such as hypertension and hypoxia driven cardiac arrhythmia leading to higher prevalence of ischemic stroke in patients with sleep disordered breathing disease. Despite strong evidence linking SDB to ischemic stroke, evaluation for SDB is rarely performed in patients presenting with an acute ischemic stroke. Hypothesis: Evaluation of SDB is rarely performed in patients presenting with acute ischemic stroke. Methods: We performed a retrospective review of all patients above the age of 18 who were admitted to the acute stroke service at University Hospital July 2014 to December 2014. Demographic data, etiology of stroke as identified per TOAST criteria, modifiable risk factors, presenting NIHSS and frequency of testing for SDB and their results were collected. The data was consolidated and tabulated by using STATA version 14. Results: Total of 240 patients satisfied our inclusion criteria. Only 24 patients ie 10% of those who satisfied our inclusion criteria received evaluation for SDB. Out of those evaluated, 62.5% ie 15 patients out of 24 patients had findings concerning for significant desaturation. Only 2 providers out of 8 stroke physicians ie 25% tested for SDB in more than 5 patients. Conclusions: Our observations highlight the paucity in evaluation for SDB in acute ischemic stroke in a tertiary care setting. Being a modifiable risk factor, greater emphasis must be placed on evaluation for SDB in patients in patients with acute stroke. Education must be provided to all patients and providers regarding identification of these factors.

Introduction: The prognosis of patients suffering acute ischemic stroke (AIS) is worsened by medical complications that occur during subsequent hospitalization. The incidence, risk factors, and outcomes of gastrointestinal bowel obstruction (GIBO) in AIS have not been previously reported. Methods: We employed the Nationwide Inpatient Sample from 2002 to 2011 to identify all patients admitted with a primary diagnosis of AIS and subsets with and without a secondary diagnosis of GIBO without hernia. Multivariate logistic regression was utilized to analyze predictors of GIBO in AIS patients and the association between GIBO, in-hospital complications, and outcomes. Results: We identified 16,987 patients with GIBO (425 per 100,000) among 3,988,667 AIS hospitalizations and 4.2% of patients of these patients underwent repair surgery for intestinal obstruction. Multivariate predictors of GIBO included: age 55-64 (OR: 1.52, 95% CI: 1.40-1.64), age 65-74 (OR: 1.69, 95% CI: 1.56-1.84), age 75+ (OR: 1.97, 95% CI: 1.81-2.13), black race (OR: 1.42, 95% CI: 1.36-1.49), coagulopathy (OR: 1.39, 95% CI: 1.29-1.50), cancer (OR: 1.59, 95% CI: 1.44-1.75), blood loss anemia (OR: 2.51, 95% CI: 2.22-2.84), fluid/electrolyte disorder (OR: 2.91, 95% CI: 2.81-3.02), weight loss (OR: 3.08, 95% CI: 2.93-3.25), and thrombolytic therapy (OR: 1.30, 95% CI: 1.20-1.42) (all p<0.0001). Patients with GIBO had a greater likelihood of suffering intubation (OR: 1.79, 95% CI: 1.70-1.90), deep vein thrombosis (OR: 1.35, 95% CI: 1.25-1.46), pulmonary embolism (OR: 1.84, 95% CI: 1.53-2.21), sepsis (OR: 2.39, 95% CI: 2.22-2.56), acute kidney injury (OR: 1.85, 95% CI: 1.76-1.95), gastrointestinal hemorrhage (OR: 2.82, 95% CI: 2.63-3.03), and blood transfusions (OR: 2.02, 95% CI: 1.90-2.15) (all p<0.0001). In adjusted analyses, AIS patients with GIBO were 284% and 39% more likely to face moderate to severe disability and in-hospital death, respectively (p<0.0001). GIBO occurrence increased length of stay and total costs by an average of 9.7 days and $22,342 (p<0.0001). Conclusion: Advanced age, black race, and several pre-existing comorbidities increase the likelihood of post-AIS GIBO, which is an independent predictor of in-hospital complications, disability, and mortality.
