PULMONARY ARTERIOVENOUS MALFORMATION (AVM) CAUSING TENSION HEMOTHORAX IN A PREGNANT WOMAN REQUIRING EMERGENT CESAREAN DELIVERY

Pulmonary Arteriovenous Malformation (AVM) Causing Tension Hemothorax in a Pregnant Woman Requiring Emergent Cesarean Delivery

Pulmonary arteriovenous malformations (PAVMs), although most commonly congenital, are usually detected later in life.We present a case of a 25-year-old woman with no previous history of AVM or telangiectasia, who presented with life-threatening hypoxia, hypotension, and pleuritic chest pain in 36th week of gestation.Chest tube placement revealed cl

An Analysis Method of Open Queueing Networks with a Degradable Structure and Instantaneous Repair Times of Systems

An unreliable open queueing network with Poisson arrivals is considered.For each queueing system the service and failures times are exponentially distributed random variables.The failures of systems lead to changes in the structure of here the network and corresponding changes in the performance measures of the queueing network.It is assumed that t
