Purpose: Evaluate concordance of provider practices with clinical guidelines for thrombectomy screening in an emergency department (ED) via computed tomography perfusion and angiogram (CT-P/A).
Methods: A retrospective observational study was conducted for patients 18 years or older who received a CT-P/A of the head and neck in a US Midwestern ED between September 2019 through June 2021. Healthcare system records reviewed for patient information, CT-P/A findings, and treatment decisions.
Results: During study period, 68,403 patients presented to the ED with 718 (1.1%) receiving a CT-P/A. Of these patients, 105 (14.6%) were transferred to a regional facility for potential thrombectomy, with 74 (70.5%) receiving procedure, 28 (26.7%) not receiving procedure, and 3 (2.9%) with insufficient follow-up information. Of patients receiving CT-P/A, 23 met DAWN criteria for thrombectomy, with 21 (91.3%) transferred for potential thrombectomy and 20 (95.2%) receiving the procedure; in comparison, 81 patients (11.7%) did not meet all DAWN criteria and were transferred for potential thrombectomy, with 52 (64.2%) receiving procedure. Lastly, 55 patients met DEFUSE-3 criteria for thrombectomy with 49 (89.1%) being transferred for potential thrombectomy and 45 (91.8%) receiving procedure. In comparison, 53 patients who did not meet all DEFUSE-3 criteria were transferred for potential thrombectomy, with 27 (50.9%) receiving procedure.
Conclusions: This study helps to understand CT-P/A usage, especially in patients that fall outside of treatment criteria in the current thrombectomy literature. Results may have value to institutions interested in using CT-P/A as a diagnostic tool as well as institutions already incorporating it in stroke assessments.

Cerebral ischemia-reperfusion injury (CIRI) constitutes a significant etiology of exacerbated cerebral tissue damage subsequent to intravenous thrombolysis and endovascular mechanical thrombectomy in patients diagnosed with acute ischemic stroke. The treatment of CIRI has been extensively investigated through a multitude of clinical studies. Acupuncture has been demonstrated to be effective in treating CIRI.

We describe a rare but interesting complication of totally endoscopic robotic mitral valve repair in a patient with severe mitral regurgitation. The mitral valve was repaired robotically by standard techniques, and the intraoperative transesophageal echocardiogram demonstrated no residual mitral regurgitation. However, there was unexpected hypokinesia of the posterior and lateral walls of the left ventricle, with subsequent electrocardiography showing acute ST elevations of the lateral segment.

This study evaluates the efficacy of deep learning models in identifying infarct tissue on computed tomography perfusion (CTP) scans from patients with acute ischemic stroke due to large vessel occlusion, specifically addressing the potential influence of varying noise reduction techniques implemented by different vendors. We analyzed CTP scans from 60 patients who underwent mechanical thrombectomy achieving a modified thrombolysis in cerebral infarction (mTICI) score of 2c or 3, ensuring minimal changes in the infarct core between the initial CTP and follow-up MR imaging. Noise reduction techniques, including principal component analysis (PCA), wavelet, non-local means (NLM), and a no denoising approach, were employed to create hemodynamic parameter maps.

Introduction: The venous outflow profile (VOP) is a crucial yet often overlooked aspect affecting stroke outcomes. It plays a major role in the physiopathology of acute cerebral ischemia, as it accounts for both the upstream arterial collaterals and cerebral microperfusion. This enables it to circumvent the limitations of various arterial collateral evaluation systems, which often fail to consider impaired autoregulation and its impact on cerebral blood flow at the microcirculatory levels.

Introduction: Cystathionine-β-synthase deficiency (CBSd) is an inherited metabolic liver disease causing morbidities in eyes, skeleton, brain, and vasculature. Despite its potential lethality due to thromboembolism and liver failure, sole diagnosis of CBSd seemed not to fulfill the enlistment criteria for deceased donor liver transplantation in previous reports.
Methods: We retrospectively reviewed three cases of living donor liver transplantation (LDLT) for pediatric CBSd patients responding poorly to conservative treatment in Beijing Friendship Hospital, and a literature review was performed.
