Background: Acute pulmonary embolism represents the third most prevalent cardiovascular pathology, following coronary heart disease and hypertension. Its untreated mortality rate is as high as 20-30%, which represents a significant threat to patient survival. In view of the current lack of real-time monitoring techniques for acute pulmonary embolism, this study primarily investigates the potential of the pulsatility electrical impedance tomography (EIT) technique for the detection and real-time monitoring of acute pulmonary embolism through the collection and imaging of the pulsatile signal of pulmonary blood flow.

Background: Petroclival meningiomas are still a neurosurgical challenge due to their proximity to cranial nerves and cerebral vasculature along the surgical corridor. The usual extension of large petroclival meningiomas is along the posterior fossa, frequently compromising and displacing adjunct cranial nerves such as the sixth and seventh-eight cranial nerve complex with brainstem compression, causing progressive neurological deficit and severe headache. The goal of sizeable petroclival meningioma surgery treatment is a maximal resection with preservation of neurological function.

In coronary artery bypass grafting (CABG) on pump, achieving optimal visualization is critical for surgical precision and safety. The use of blowers to clear the CABG anastomosis poses risks, including the formation of micro-embolic gas bubbles, which can be insidious and increase the risk of cerebral or myocardial complications. This retrospective study compares the effectiveness of the use of irrigation mist and CO versus a direct CO blower without irrigation in terms of visualization, postoperative fibrillation, and micro-embolic gas activity.

During drought, the formation of air bubbles known as embolisms in the water-conducting xylem reduces hydraulic conductivity, which can ultimately result in tree death. Accurately quantifying vulnerability to embolism formation is therefore essential for understanding tree hydraulics. Acoustic emission (AE) analysis offers a non-destructive method to monitor this process, yet the interpretation of captured signals remains debated.

Article Synopsis
- The popularity of atrial catheter ablation has surged as a leading treatment for supraventricular tachycardias, praised for its safety and effectiveness.
- Complications can occur at various stages, including vascular, thromboembolic, and mechanical issues, with atrial fibrillation ablation being notably riskier due to its complexity.
- Strategies to minimize risks involve advanced techniques like optimized anticoagulation and esophageal temperature monitoring, while emerging methods like pulsed-field ablation show promise for improved safety, pending further research.
