Extensive Arterial Dissection: A Rare Multivascular Emergency.
Cureus
December 2024
Internal Medicine, Hospital de Braga, Braga, PRT.
Aortic dissection is a life-threatening vascular emergency associated with high morbidity and mortality. Clinical manifestations might include severe chest pain to neurological deficits, depending on the arterial segments involved. Extensive dissections involving multiple aortic segments and branch vessel occlusions, such as the carotid arteries, are rare and pose unique diagnostic and therapeutic challenges.

Snakebites are critical medical emergencies that significantly contribute to emergency department visits during monsoon seasons. This case report details a patient who experienced simultaneous arterial and venous thrombosis of major intracranial vessels due to venom-induced consumptive coagulopathy. Additionally, the patient developed diffuse alveolar haemorrhage (DAH), highlighting the severe impact of these uncommon complications on prognosis.

Intestinal ischemia-reperfusion (I/R) injury occurs under various surgical or disease conditions, where tissue hypoxia followed by reoxygenation results in the production of oxygen radicals and inflammatory mediators. These substances can target the endothelial barrier, leading to microvascular leakage. In this study, we induced intestinal I/R injury in mice by occluding the superior mesenteric artery, followed by removing the clamp to resume blood circulation.

Objectives: To investigate the efficacy of prophylactic embolization of the internal iliac artery (IIA) or superior gluteal artery (SGA) before open reduction and internal fixation (ORIF) in reducing intraoperative blood loss (IBL) in hemodynamically stable patients with complex acetabular fractures.
Materials And Methods: A total of 136 patients with complex acetabular fractures were retrospectively included and divided into the prophylactic transcatheter arterial embolization (PTAE) group and non-PTAE group, depending on whether ipsilateral IIA or SGA was embolized using coils within 3 days before ORIF. Demographic characteristics, injury severity score (ISS), fracture classification, and intraoperative and postoperative data were compared between the two groups.
IL-34 aggravates myocardial ischemia-reperfusion injury by upregulating the HMGB1-IL-17A-IL-6 axis through the JAK signaling pathway.

Interleukin-34 (IL-34) was recently reported to be a new biomarker for atherosclerosis diseases, such as coronary artery disease and vascular dementia. IL-34 regulates the expression of proinflammatory cytokines (IL-17A, IL-1 and IL-6), which are classical cytokines involved in myocardial ischemia‒reperfusion (MI/R) injury. However, the exact role of IL-34 in MI/R remains unknown.
