Acute mesenteric ischemia due to superior mesenteric artery embolism in a patient with permanent atrial fibrillation

Abstract

Acute mesenteric ischemia (AMI) is an uncommon disorder with a high mortality rate. Reduction in mortality requires a high index of suspicion and prompt diagnosis. We describe a case of AMI in a 59-year old man with a history of permanent atrial fibrillation. Pathogenesis of AMI, clinical implications, diagnostic and therapeutic options are discussed.

 

Key words: thromboembolism, superior mesenteric artery, diagnosis, mesenteric angiography

Refractory ventricular fibrillation with prolonged resuscitation in dialysis-sensitive dysrhythmic patient

Abstract

Sudden cardiac death is a leading cause of death in chronic renal failure patients. We present a case of refractory ventricular fibrillation with successful prolonged resuscitation (> 1 hour) without neurological sequel in an outpatient dialysis centre. Implantation of a cardioverter-defibrillator is able to identify patients as dialysis-sensitive. Smoother potassium removal during hemodialysis could eliminate dysrhythmias. Prehospital (point-of-care) blood gas analysis can be helpful especially in prolonged resuscitation.
