White cord syndrome after non-contiguous double-level anterior cervical decompression and fusion (ACDF): A “no reflow phenomenon”?
2017
Abstract Study design Case report and review of literature. Objective To report a rare complication of anterior cervical decompression and fusion (ACDF) in a patient with severe cervical cord compression and review of relevant literature. Introduction The white cord syndrome is a very rare condition characterized by an ischemic-edematous lesion of the spinal cord following a surgical procedure, lacking intra o perioperative surgical or anesthesiological complications. Case report A 64-years old male affected by a severe cervical stenosis at multiple levels, with voluminous C3–C4 and C5–C6 disc herniations associated to T2-hyperintense myelomalacic area at C3–C4 level was admitted to our Uni…
Coronary microvascular dysfunction
2020
Patients with coronary microvascular dysfunction (CMVD) represent a widespread population and despite the good prognosis, many of them have a poor quality of life with strong limitations in their daily activities because of the angina symptoms. This article summarizes the most frequent clinical presentation pictures like stable and unstable microvascular angina. Main risk factors are discussed, followed by the latest updates on the subject about different pathogenic hypotheses, diagnosis and treatment. Not very well understood microvascular alterations, like slow flow phenomenon and no reflow are discussed and both prognosis and the impact of the disease in the quality of life are analyzed.
Influence of the terminal complement-complex on reperfusion injury, no-reflow and arrhythmias: a comparison between C6-competent and C6-deficient rab…
1996
Objective: The complement system has been suggested to play a role in reperfusion injury which may result from an enhanced destruction of myocardial tissue or from an impairment of reflow. We investigated the influence of the C5b-9 complement complex on infarct size, reflow and arrhythmogenesis. Methods: Twenty-eight C6-competent rabbits and 18 rabbits with congenital C6 deficiency were subjected to either 30 min or 2 h of coronary artery occlusion followed by reperfusion. C6 deficiency was confirmed by the complement titration test and immunohistology. The triphenyl tetrazolium chloride method was used to delineate infarct size. Reflow into infarcted areas was evaluated histologically afte…
Rationale and design of the EMBRACE STEMI Study: A phase 2a, randomized, double-blind, placebo-controlled trial to evaluate the safety, tolerability …
2012
Background Although significant efforts have been made to improve ST-segment elevation myocardial infarction (STEMI) outcomes by reducing symptom-onset-to-reperfusion times, strategies to decrease the clinical impact of ischemic reperfusion injury have demonstrated limited success. Bendavia, an intravenously administered mitochondrial targeting peptide, has been shown to reduce myocardial infarct size and attenuate coronary no-reflow in experimental modelswhen given before reperfusion. Design The EMBRACE STEMI study is a phase 2a, randomized, double-blind, placebo-controlled trial enrolling 300 patients with a first-time anterior STEMI and an occluded proximal or mid–left anterior descendin…
