BACKGROUND Intestinal ischemia after cardiac surgery is a rare but severe complication with a high mortality. Early surgery can be lifesaving. The aim was to analyze the incidence, outcome, and risk factors for these patients. METHODS A prospectively collected database with patients who underwent 18,879 cardiac surgical procedures between 1996 and 2011 was investigated. All patients with regi...
RATIONALE Blood vessel growth and patterning have been shown to be regulated by nerve-derived signals. Desert hedgehog (Dhh), one of the Hedgehog family members, is expressed by Schwann cells of peripheral nerves. OBJECTIVE The purpose of this study was to investigate the contribution of Dhh to angiogenesis in the setting of ischemia. METHODS AND RESULTS We induced hindlimb ischemia in wild...
Thoracoabdominal aneurysm surgery carries an approximate 10% risk of intraoperative paraplegia. Abrupt cord ischemia and the confounding effects of systemic alterations and limb or cerebral ischemia challenges neurophysiologic spinal cord monitoring. This investigation sought a rapid differential monitoring approach to predict or help prevent paraplegia. Thirty-one patients were monitored with ...
Abstract Background Fulminant Myocarditis (FM) leads to cardiogenic shock with multi-organic dysfunction, being peripheral venoarterial extracorporeal membranous oxygenation (VA-ECMO) a rescue technique. Despite growing experience, it is still related several complications. We aim appraise the management of patients FM and adverse events associated VA-ECMO. Methods conducted retrospective study...
Background—Critical limb ischemia, a manifestation of severe peripheral atherosclerosis and compromised lowerextremity blood flow, results in a high rate of limb loss. We hypothesized that adenoviral delivery of a constitutively active form of the transcription factor hypoxia-inducible factor-1 (ie, Ad2/HIF-1 /VP16 or HIF-1 ) into the lower extremity of patients with critical limb ischemia woul...
OBJECTIVES The purpose of this study was to assess whether: 1) very small increases in troponin T, measured by a new highly sensitive cardiac troponin T (hs-cTnT), may reflect ischemia without necrosis; and 2) serial changes can discriminate ischemia from other causes of cardiac troponin T (cTnT) release. BACKGROUND A new hs-cTnT assay offers greater sensitivity than current assays. METHODS...
Musculoskeletal pain due to ischemia is present in a variety of clinical conditions including peripheral vascular disease (PVD), sickle cell disease (SCD), complex regional pain syndrome (CRPS), and even fibromyalgia (FM). The clinical features associated with deep tissue ischemia are unique because although the subjective description of pain is common to other forms of myalgia, patients with i...
BACKGROUND Critical limb ischemia, a manifestation of severe peripheral atherosclerosis and compromised lower-extremity blood flow, results in a high rate of limb loss. We hypothesized that adenoviral delivery of a constitutively active form of the transcription factor hypoxia-inducible factor-1alpha (ie, Ad2/HIF-1alpha/VP16 or HIF-1alpha) into the lower extremity of patients with critical limb...
