Thermodilution continuous cardiac output measurements (TDCCO) by pulmonary artery catheter (PAC) have not been validated during therapeutic hypothermia in post-cardiac arrest patients. The calculated cardiac output based on the indirect Fick principle (FCO) using pulmonary artery blood gas mixed venous oxygen saturation (FCO-BG-SvO2) is considered as the gold standard. Continuous ...

Eosinophilic coronary monoarteritis is an unfamiliar cause of acute myocardial ischemia. Most commonly, it presents as a left-sided chest pain or sudden death in middle-aged women with no traditional risk factors for coronary artery disease. Because the abrupt onset leaves almost no time for intervention, the symptoms readily lead to ...

Open surgical disconnection has long been the treatment of choice for dural arteriovenous fistulas (dAVFs) of the anterior cranial fossa. However, advanced patient age and the presence of medical comorbidities can substantially increase the risk of craniotomy and favor a less invasive endovascular approach. Optimal positioning within the distal ophthalmic ...
