Adequacy of central hemodynamics versus restoration of circulation in the survival of patients with acute aortic thrombosis

American Journal of Surgery

Abstract

Acute aortic thrombosis is an infrequent clinical occurrence, but when it does occur, it is a true cardiovascular catastrophe. Our experience with 34 patients over a 12 year period was reviewed and factors influencing outcome were analyzed. Seventeen women and 17 men had various clinical presentations, although 74 percent of the patients had the classic picture of ischemia. Preoperative assessment of left ventricular function was carried out in all but one patient with intraoperative and perioperative monitoring to guide therapy in addition to revascularization procedures. While extent of the preexisting disease and number of additional operations did influence the outcome, the predominant factor for survival was the left ventricular functional state perioperatively. Fifteen of the 16 patients with adequate left ventricular function survived, whereas 15 of the 17 patients with a failing myocardium died (88 percent). Extraanatomic operations are preferable in patients with demonstrated inadequate left ventricular function. Expeditious restoration of circulation alone does not ensure a favorable outcome. The key to successful therapy is understanding, preventing, and effectively treating the mechanical and metabolic dysfunction o...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Alzheimer's Disease: MS4A

Variants within the membrane-spanning 4-domains subfamily A (MS4A) gene cluster have recently been implicated in Alzheimer's disease in genome-wide association studies. Here is the latest research on Alzheimer's disease and MS4A.

Pediculosis pubis

Pediculosis pubis is a disease caused by a parasitic insect known as Pthirus pubis, which infests human pubic hair, as well as other areas with hair including eye lashes. Here is the latest research.

Rh isoimmunization is a potentially preventable condition that occasionally is associated with significant perinatal morbidity or mortality. Discover the latest research on Rh Isoimmunization here.

Genetic Screens in iPSC-derived Brain Cells

Genetic screening is a critical tool that can be employed to define and understand gene function and interaction. This feed focuses on genetic screens conducted using induced pluripotent stem cell (iPSC)-derived brain cells. It also follows CRISPR-Cas9 approaches to generating genetic mutants as a means of understanding the effect of genetics on phenotype.
