Brain strain: Blood flow and metabolism in environmental extremes

Experimental Physiology, EarlyView.
Abstract This narrative review compares and contrasts the most commonly encountered environmental stressors on human cerebrovascular functioning. From high altitude and space, extreme apnoea, heat and cold stress, the impact of these stressors on the regulation of cerebral blood flow (CBF) and oxygen metabolism (CMRO2${\mathrm{CM}}{{\mathrm{R}}_ ...

Accuracy of core temperature measurement in deep hypothermic circulatory arrest [PDF]

Interactive CardioVascular and Thoracic Surgery, 2008
Deep hypothermia is an effective technique for neuroprotection in cardiac surgery. However, standard body temperature measurement may deviate from actual brain temperature. Therefore, we simultaneously measured brain and core temperatures during neurosurgical interventions in hypothermic circulatory arrest to determine its accuracy.

Potential health benefits of cold‐water immersion: the central role of PGC‐1α

The Journal of Physiology, EarlyView.
Abstract figure legend Cold‐water immersion (CWI) elicits autonomic, somato‐motoric (shivering thermogenesis), endocrine and metabolic, sensory transduction, and local biophysical effects that may converge on the transcriptional co‐activator PGC‐1α (centre).

Iatrogenic intramural hematoma of the ascending aorta complicating inadvertent arterial cannulation during central venous catheter placement. A case report and review of the literature

Annals of Cardiac Anaesthesia, 2020
Aortic injury during central venous catheter (CVC) insertion is a rare but serious complication. This presentation describes a case of iatrogenic intramural hematoma of the ascending aorta complicating inadvertent arterial cannulation of the right ...

Surgical treatment of thoracic aortic pseudoaneurysm caused by Brucella melitensis

Journal of Cardiothoracic Surgery, 2023
Thoracic aortic pseudoaneurysm caused by Brucella melitensis is extremely rare with extremely few cases reported to date. Herein, we present the case of a 65 year-old man with a huge pseudoaneurysm of the proximal descending thoracic aorta, involving the

A rare case of vena cava leiomyoma: A case report

Annals of Cardiac Anaesthesia, 2021
Intravascular leiomyoma is an uncommon disease and depending of vascular involvement and anesthetic challenge. We review a case of a 53-year-old woman who underwent vena cava leiomyoma resection under cardiopulmonary bypass using deep hypothermic ...

Reduced cardiovascular mortality at moderate altitude: a putative role of physical activity and body mass

The Journal of Physiology, EarlyView.
Abstract figure legend Benefits of performing physical exercise at moderate altitude. At moderate altitude, increased resting metabolic rate and physical exertion promote physical fitness and exercise tolerance, whereas hypoxia suppresses appetite and elicits adaptations that increase tissue O2 delivery while augmenting O2‐independent ATP production ...

Sutureless aortic valve implantation in patient with porcelain aorta via unclamped aorta and deep hypothermic circulatory arrest

Annals of Cardiac Anaesthesia, 2017
Severe atherosclerotic calcification of the ascending aorta, the so-called porcelain aorta, precludes cardiac surgeons from placing an aortic cross-clamp and direct aortic cannulation due to the increased risk of systemic embolism and stroke.

Unique One‐Stage Procedure: Simultaneous Patent Foramen Ovale Closure and Resection of Wilms Tumor With Vena Cava Thrombus in a 5‐Year‐Old

Clinical Case Reports, Volume 14, Issue 8, August 2026.
Combined cardiac and abdominal surgery in a child with nephroblastoma, inferior vena cava tumor thrombus extending to the right atrium, and patent foramen ovale. ABSTRACT Wilms tumor with intravascular extension poses significant surgical challenges, particularly when combined with a patent foramen ovale, which adds the risk of paradoxical embolism. We
