Peri-operative Monitoring of an Asystolic Cardiac Arrest Requiring Cardiopulmonary Resuscitation During Carotid Endarterectomy for Symptomatic Carotid Artery Stenosis.

Introduction: A carotid endarterectomy (CEA) has certain risks, of which peri-operative cardiovascular risk is one. Peri-operative neurological monitoring can be done with electroencephalography (EEG) and transcranial Doppler (TCD). No previous reports have been published demonstrating the actual changes in cerebral and cardiac activity during a peri-operative asystole.

Optimal Treatment Strategy in Rectal Cancer Surgery: Should We Be Cowboys or Chickens?

Background And Purpose: Surgeons and hospitals are increasingly accountable for their postoperative complication rates, which may lead to risk adverse treatment strategies in rectal cancer surgery. It is not known whether a risk adverse strategy leads to providing better care. In this study, the association between the strategy of hospitals regarding defunctioning stoma construction and postoperative outcomes in rectal cancer treatment was evaluated.

Treatment of types II-IV endoleaks by injecting biocompatible elastomer (PDMS) in the aneurysm sac: an in vitro study.

Purpose: To investigate if an elastomer [polydimethylsiloxane (PDMS)] can be used to effectively treat endoleaks after endovascular aneurysm repair.

Methods: A latex aneurysm (36-mm inner diameter sac, 15-mm inner diameter neck) was attached to an in vitro circulation model. The aneurysm was excluded from the circulation by placing an unstented polyester graft.

The effect of injectable biocompatible elastomer (PDMS) on the strength of the proximal fixation of endovascular aneurysm repair grafts: an in vitro study.

Purpose: One of the major concerns in the long-term success of endovascular aneurysm repair (EVAR) is stent graft migration, which can cause type I endoleak and even aneurysm rupture. Fixation depends on the mechanical forces between the graft and both the aortic neck and the blood flow. Therefore, there are anatomical restrictions for EVAR, such as short and angulated necks.

Aortic customize: a new alternative endovascular approach to aortic aneurysm repair using injectable biocompatible elastomer. An in vitro study.

Purpose: Aortic Customize is a new concept for endovascular aortic aneurysm repair in which a non polymerized elastomer is injected to fill the aneurysm sac around a balloon catheter. The aim of this in vitro study was to investigate the extent of aneurysm wall stress reduction by the presence of a noncompliant elastomer cuff.

Methods: A thin-walled latex aneurysm (inner radius sac 18 mm, inner radius neck 8 mm), equipped with 12 tantalum markers, was attached to an in vitro circulation model.
