AI Article Synopsis
Article Abstract
We report a case of a patient who suffered a massive pulmonary embolism with cardiac arrest on post-operative day 4 after a Whipple operation. Despite thrombolytic therapy with the recommended maximal bolus of 50 mg recombinant tissue type plasminogen activator (rt-PA), thrombelastometry showed no signs of fibrinolysis and cardiogenic shock persisted, after only a transient hemodynamic improvement. Not until a repeat bolus of 25 mg rt-PA and an infusion of 50 mg/h did thrombelastometry demonstrate complete fibrinolysis. Although only residual emboli were seen on computed tomography, the patient died secondary to refractory right heart failure. This demonstrates that the standard dosing of thrombolytics may fail in a subgroup of patients, and suggests that thrombelastometry may be useful for early dose adjustment when standard dosing regimens fail.

Artificial biomarker-based feedback-regulated personalized and precise thrombolysis with lower hemorrhagic risk.

The body weight-based thrombolytic medication strategy in clinical trials shows critical defects in recanalization rate and post-thrombolysis hemorrhage. Methods for perceiving thrombi heterogeneity of thrombolysis resistance is urgently needed for precise thrombolysis. Here, we revealed the relationship between the thrombin heterogeneity and the thrombolysis resistance in thrombi and created an artificial biomarker-based nano-patrol system with robotic functional logic to perceive and report the thrombolysis resistance of thrombi.

Background: Aneurysmal subarachnoid haemorrhage continues to cause a significant burden of morbidity and mortality despite advances in care. Trials investigating local administration of thrombolytics have reported promising results.
Objectives: - To assess the effect of thrombolysis on improving functional outcome and case fatality following aneurysmal subarachnoid haemorrhage - To determine the effect of thrombolysis on the risk of cerebral artery vasospasm, delayed cerebral ischaemia, and hydrocephalus following subarachnoid haemorrhage - To determine the risk of complications of local thrombolysis in aneurysmal subarachnoid haemorrhage SEARCH METHODS: We searched the Cochrane Central Register of Controlled Trials (last searched 9 March 2023), MEDLINE Ovid (1946 to 9 March 2023), and Embase Ovid (1974 to 9 March 2023).

Background And Objectives: The optimal management of high-risk and intermediate-high-risk Pulmonary Embolism (PE) is a matter of ongoing debate. This paper aims to assess the short and long-term clinical outcomes associated with different treatment approaches for high-risk and intermediate-high-risk PE within an Intensive Care Unit (ICU) and identify potential areas for improvement.
Methods: We conducted a retrospective analysis of patients admitted to an ICU with high and intermediate-high-risk PE between January 2018 and December 2023.

Background: Hemorrhagic transformation (HT) is a complication of reperfusion therapy following acute ischemic stroke (AIS). We aimed to develop and validate a model for predicting HT and its subtypes with poor prognosis-parenchymal hemorrhage (PH), including PH-1 (hematoma within infarcted tissue, occupying < 30%) and PH-2 (hematoma occupying ≥ 30% of the infarcted tissue)-in AIS patients following intravenous thrombolysis (IVT) based on noncontrast computed tomography (NCCT) and clinical data.
Methods: In this six-center retrospective study, clinical and imaging data from 445 consecutive IVT-treated AIS patients were collected (01/2018-06/2023).
Bayesian modeling framework for optimizing pre-hospital stroke triage decisions.

Ischemic stroke is responsible for significant morbidity and mortality in the United States and worldwide. Stroke treatment optimization requires emergency medical personnel to make rapid triage decisions concerning destination hospitals that may differ in their ability to provide highly time-sensitive pharmaceutical and surgical interventions. These decisions are particularly crucial in rural areas, where transport decisions can have a large impact on treatment times - often involving a trade-off between delay in pharmaceutical therapy or a delay in endovascular thrombectomy.
