Delayed Contrast-Enhanced MR Angiography for the Assessment of Internal Carotid Bulb Patency in the Context of Acute Ischemic Stroke: An Accuracy, Interrater, and Intrarater Agreement Study

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.

Aim: to study the stroke-associated pneumonia (SAP) effect on the outcome of ischemic stroke (IS) in the internal carotid artery system. Patients and Methods: 87 patients with IS underwent the follow-up study, of which 75 had no inflammatory bronchopulmonary complications (group 1), and 12 had pneumonia manifestation (group 2). The study was performed on days 1, 5, and 9 after IS, and 6 months and 12 months after discharge from the hospital. Neurological deficit severity (NIHSS, Barthel index) and inflammatory markers (peripheral blood leukocyte composition, C-reactive protein (CRP), ESR) were studied. Results: it was found that the presence of SAP was associated with increased mortality during the acute IS period (4 (33.1%) patients died in group 1 and 10 (13.3%) — in group 2, p<0.05), greater severity of neurological deficits (63.3±5.3 and 71.5±4.0 points on the NIHSS scale, respectively, p<0.05) and incapacitation (Barthel index — 63.3±5.3 and 71.5±4.0 points, respectively, p<0.05) at the end of the inpatient treatment period. In group 2, signs of an inflammatory response were detected on day 5, and the values of the white blood cell shift index, ESR and CRP significantly (p<0.05) differed from the initial values. During examination at 6 months and 12 months, there were no significant differences in these indicators between the groups. An association was established between the probability of SAP occurrence and the presence of swallowing disorders (r=0.672; p<0.05), the age of patients (r=0.572; p<0.05) and the presence of diabetes mellitus (r=0.522; p<0.05). The studied laboratory inflammatory markers allow us to timely assume the occurrence of pulmonary pathology. Conclusion: timely diagnosis and prevention of SAP can reduce the risk of fatal outcome, facilitate rehabilitation measures, and improve early IS outcomes.

First Pass

Background and Purpose: Achieving complete revascularization after a single pass of a mechanical thrombectomy device (first pass effect [FPE]) is associated with good clinical outcomes in patients with acute ischemic stroke due to large vessel occlusion. We assessed patient characteristics, outcomes, and predictors of FPE among a large real-world cohort of patients (Systematic Evaluation of Patients Treated with Stroke Devices for Acute Ischemic Stroke registry). Methods: Demographics, clinical outcomes, and procedural characteristics were analyzed among patients in whom FPE (modified Thrombolysis in Cerebral Infarction 2c/3 after first pass) was achieved versus those requiring multiple passes (MP). Modified FPE and modified MP included patients achieving modified Thrombolysis in Cerebral Infarction 2B-3. Primary outcomes included 90-day modified Rankin Scale (mRS) score and mortality. Results: Among 984 Systematic Evaluation of Patients Treated with Stroke Devices for Acute Ischemic Stroke patients, 930 had complete 90-day follow-up. FPE was achieved in 40.5% (377/930) of patients and MP in 20.0% (186/930). Baseline characteristics were similar across all groups. The FPE group had fewer internal carotid artery occlusions compared with MP ( P =0.029). The FPE group had faster puncture to recanalization time ( P ≤0.001), higher rates of 90-day mRS score of 0 to 1 (52.6% versus 38.6%, P =0.003), mRS score of 0 to 2 (65.4% versus 52.0%, P =0.003), and lower 90-day mortality compared with the MP group (12.0% versus 18.7%, P =0.038). Similarly, compared with modified MP patients, the modified FPE group had fewer internal carotid artery occlusions ( P =0.004), faster puncture to recanalization time ( P ≤0.001), and higher rates of 90-day mRS score of 0 to 1 ( P =0.002) and mRS score of 0 to 2 ( P =0.003). Conclusions: Our findings demonstrate that FPE and modified FPE are associated with superior clinical outcomes.
