Background: To date, it has been assumed that acute seizures which arise in the context of sudden, spontaneous, atraumatic, acute, arterial dissections (SAAADs) are downstream consequences of the dissections driven by syncope or focal brain lesions (FBLs). As this subject has not been formally investigated, likely due to its rarity, we reviewed published case reports (CRs) to examine the veracity of this assumption.

Methods: We included CR describing patients diagnosed with both acute seizures and arterial dissections in order to ascertain the temporal sequence between acute seizures and typical SAAAD symptoms.

The objective of this review was to assess the diagnostic accuracy of bedside-focused transthoracic echocardiography (TTE) in acute atraumatic thoracic aortic syndrome in adults. We performed a systematic review and meta-analysis of publications that described the use of bedside-focused TTE on adults presenting to emergency care settings with suspected atraumatic thoracic aortic syndrome. Studies were identified using keyword and MeSH on relevant databases as well as grey literature, followed by abstract screening and study selection by two independent reviewers.

Introduction: Ischemia-reperfusion (IR) injury is a major concern that frequently occurs during vascular surgeries. Hydrogen-rich saline (HRS) solution exhibits antioxidant and anti-inflammatory properties. This study aimed to examine the effects of HRS applied before ischemia in the lungs of rats using a lower extremity IR model.

Background: Experimental animal models of ischemic spinal cord injury (iSCI) are essential for studying its pathogenesis and for developing new therapeutic strategies to improve functional recovery in humans. Many existing models, however, exhibit high variability or early lethality. A reliable experimental iSCI model would significantly advance novel treatment approaches for these severe neurological disorders.

Article Synopsis
  • - The study introduces a new technique for safely cannulating difficult target vessels during fenestrated/branched endovascular aortic repair (F/B-EVAR).
  • - This method utilizes multiple fine, atraumatic guidewires to create a stiffer guidewire, allowing for successful access to challenging vascular anatomy.
  • - The technique is illustrated through a case involving a complex abdominal aortic aneurysm, demonstrating its practicality and cost-effectiveness for physicians dealing with tough-to-reach vessels.
