Arterial Recanalization

Background: Data on arterial recanalization after IV t-PA treatment are rare. IMS-3 allows the study of variables affecting arterial recanalization after IV t-PA in acute ischemic stroke patients with CTA-proved major artery occlusions. Methods: Of 656 acute ischemic stroke patients in IMS-3, 306 were examined with baseline CTA and randomized either to IV t-PA (N=95) or to IV t-PA followed by digital subtraction angiography (DSA) and endovascular therapy (EVT) (N=211). Comparison of baseline CTA to DSA within 5 hours of stroke onset assessed early arterial recanalization after IV t-PA. A central core lab categorized DSA vessel occlusion as “no, partial, or complete”. We studied the association between arterial occlusion sites on baseline CTA with early recanalization for the endovascular group and analyzed its impact on clinical outcome at 90 days. Results: In the EVT group, 22 patients (10.4%) had no CTA intracranial occlusions, but 1 extracranial occlusion; 42 patients (19.9%) had occlusions of intracranial internal carotid artery (ic-ICA); 10 patients (4.7%) had tandem occlusions of the cervical ICA and middle cerebral artery (MCA); 95 patients (45.0%) had MCA-trunk (M1) occlusions, 33 patients (15.6%) had M2 occlusions, 3 patients (1.4%) had M3/4 occlusions, and 6 patients (2.8%) occlusions within posterior circulation. Partial or complete recanalization occurred in 28.6% of patients before DSA and was marginally associated with occlusion site (p=0.0525) (8 patients (19.0%) with ic-ICA occlusion, 0 patients with tandem ICA/MCA occlusions, 34 patients (35.8%) with M1 occlusions, 11 patients (33.3%) with M2 occlusions, 0 patients with M3/4 occlusions, and 1 patient (16.7%) with occlusion within posterior circulation). Three CTA negative patients had intracranial occlusions on DSA. Thirty-two patients (59.3%) with early recanalization achieved mRS of 0-2 at 90 days compared to 51 patients (38.4%) without early recanalization (p=0.0099). There was no relationship between early recanalization and time to IV t-PA or mean t-PA dose. Conclusion: Before EVT, IV rt-PA may facilitate arterial recanalization and better clinical outcome in about one third of patients.

The Impact

Background and Purpose— A distinguishing feature of our Stroke Network is telestroke nurses who remotely facilitate evaluations. To enable expeditious transfer of large vessel occlusion (LVO) acute ischemic stroke patients presenting to nonthrombectomy centers, the telestroke nurses must immediately identify color thresholded computerized tomography perfusion (CTP) patterns consistent with internal carotid artery (ICA), middle cerebral artery (MCA) segment 1(M1), and MCA segment 2 (M2) LVO acute ischemic stroke. Methods— We developed a 6-month series of tutorials and tests for 16 telestroke nurses, focusing on CTP pattern recognition consistent with ICA, M1, or M2 LVO acute ischemic stroke. We simultaneously conducted a prospective cohort study to evaluate the impact of this intervention. Results— Telestroke nurses demonstrated good accuracy in detecting ICA, M1, or M2 LVO during the first 3 months of teaching (83%–94% accurate). This significantly improved during the last 3 months (99%–100%), during which the likelihood of correctly identifying the presence of any one of these LVOs exceeded that of the first 3 months ( P <0.001). There was a higher probability of correctly identifying any CTP pattern as consistent with either an ICA, M1, or M2 occlusion versus other types of occlusions or nonocclusions (odds ratio, 5.22 [95% CI, 3.2–8.5]). Over time, confidence for recognizing CTP patterns consistent with an ICA, M1, or M2 LVO did not differ significantly. Conclusions— A series of tutorials and tests significantly increased the likelihood of telestroke nurses correctly identifying CTP patterns consistent with ICA, M1, or M2 LVOs, with the benefit of these tutorials and test reviews peaking and plateauing at 4 months.

Favorable Clinical Outcome

Background Mechanical thrombectomy (MT) became a standard of care for patients with acute ischemic stroke (AIS) with its efficacy demonstrated by meta-analysis and randomized studies. Although ischemic stroke is associated more with older patients, it may also have devastating neurological effects on young patients. Purpose To present our experience with stroke patients aged <50 years treated with endovascular means and to evaluate clinical and procedural factors associated with outcome and mortality. Material and Methods This study was conducted on 34 young stroke patients treated with MT. Clinical features including baseline results, radiological imaging, procedural details, and outcome results were documented and evaluated. Recanalization was assessed according to the TICI score. The clinical condition was evaluated after three months using mRS. Mortality rate was calculated. Results The rate of successful recanalization (TICI ≥2c) was 79% (27/34). Symptomatic intracranial hemorrhage (sICH) was observed in 5 (15%) patients. After 90 days, the mortality rate was 12%. Favorable clinical outcome (mRs 0–2) was regained in 65% of the patients whereas satisfactory clinical outcome was seen in 85%. Poor clinical outcome (mRs >2) was observed in 9 (23.7%) patients. Conclusion In conclusion, the results of this study demonstrate that MT for AIS in young patients is feasible and provides an excellent rate of arterial recanalization and high rate of favorable outcomes. Statistical analysis showed that shorter time from onset to arrival and reperfusion, successful recanalization and absence of hemorrhagic transformation are the predictors of favorable clinical outcome and overall survival rate.

Tissue Plasminogen

The endovascular clot retrieval in combination with intravenous recombinant tissue plasminogen activator (rtPA) has been established as the 1st choice therapy for the treatment of acute arterial ischemic stroke (AIS) in case of large vessel occlusion. While the results of this therapy in ischemic insults in the anterior stromal region are clearly positive, the results for mechanical thrombectomy in posterior circulation are controversially discussed. In addition, the indication is made by the time window, sizing of the ischemic area, and various scores. The aim of the article is to review the available reports on the use of thromboelastography in acute ischemic stroke patients.

     ASSOCIATION BETWEEN GASTROINTESTINAL BLEEDING WITH CLINICAL OUTCOME ACUTE ISCHEMIC STROKE PATIENTABSTRACTIntroduction: Gastrointestinal bleeding associated by the delay in the administration of antiplatelet and anticoagulant, thus affected the clinical outcome and patient treatment.Aims: To find the association between gastrointestinal bleeding and clinical outcome in acute ischemic stroke patient.Methods: This study was a prospective observational, conducted at Hasan Sadikin Hospital Bandung in November 2017 to February 2018. Acute ischemic stroke patients that fulfill the inclusion and exclusion criteria were observed while being treated in the ward and the survival rate and length of stay were studied. This study used univariate, bivariate, multivariate, and stratification analysis.Results: In the study period, 100 acute ischemic stroke patients were found and 24 patients had gastrointestinal bleeding. A history of previous peptic ulcer/gastrointestinal bleeding was found in patient with gastrointestinal bleeding (20.8%). Median NIHSS score was higher (16 vs 7) and GCS score was lower (12 vs 15) in patients with bleeding. Multivariate analysis showed that gastrointestinal bleeding were significantly associated with survival and length of stay. The analysis of stratification showed subjects with infections who later experienced gastrointestinal bleeding had a lower risk of death and length of stay than subjects without infection who experienced gastrointestinal bleeding (1.7  vs  22.5 times and 1.5 vs 2 times).Discussion: Ischemic stroke with gastrointestinal bleeding had higher mortality and length of stay than without gastrointestinal bleeding in acute ischemic stroke patient.Keyword: Acute ischemic stroke, gastrointestinal bleeding, length of stay, mortalityABSTRAKPendahuluan: Perdarahan gastrointestinal berhubungan dengan penundaan terapi antiplatelet atau antikoagulan, sehingga berpengaruh terhadap luaran dan tata laksana pasien.Tujuan: Mengetahui hubungan perdarahan gastrointestinal dengan luaran pasien stroke iskemik akut.Metode: Penelitian prospektif observasional terhadap pasien stroke iskemik akut di RSUP Dr. Hasan Sadikin, Bandung pada bulan November 2017 hingga Februari 2018.

The coronavirus disease 2019 (COVID-19) pandemic has caused millions of deaths worldwide. Acute ischemic stroke is a life-threatening risk factor for COVID-19 infection. Neutrophil-to-lymphocyte ratio (NLR) is one of the predictors of poor prognosis in acute ischemic stroke. The aim of this study was to assess the correlation between NLR values and the clinical outcome of acute thrombotic stroke patients with COVID-19 that was measured using the National Institutes of Health Stroke Scale (NIHSS). A cross-sectional hospital-based study was conducted in Dr. Soetomo General Hospital Surabaya, Indonesia. Patients with acute thrombotic stroke and COVID-19 admitted between 1 March 2020 and 31 May 2021 were recruited. The NLR values and the NIHSS scores were assessed during the admission and the correlation between NLR and NIHSS scores was calculated. This study included 21 patients with acute thrombotic stroke and COVID-19, consisting of 12 males and 9 females. The mean age was 57.6 years old. The mean NLR values was 8.33±6.7 and the NIHSS scores ranging from 1 to 33. Our data suggested a positive correlation between NLR values and NIHSS scores, r=0.45 with p=0.041. In conclusion, the NLR value is potentially to be used as a predictor of the clinical outcome in acute thrombotic stroke patients with COVID-19. However, further study is warranted to validate this finding.
