This study suggests that ER is safe, sharing the same perioperative mortality risk as OR despite 44% of the ER group being rejected as unfit for OR. Conventional open repair is the most reliable method of successfully managing AAA. The endoluminal method, however, results in shorter length of hospital stay, shorter length of intensive care unit stay, and less blood loss than the open method. Patients who opt for the endoluminal method of repair should be made aware that the minimally invasive technique carries the disadvantage of a higher failure rate.
Excluded AAAs can increase in size owing to persistent or recurrent pressurization (endotension) of the sac even when there is no evidence of endoleak. One proposed mechanism is pressure transmission via thrombus that lines the attachment site. Endotension may also represent an indiscernible, very low flow endoleak that allows blood to clot at the source of leakage.
In this document the authors continue to refine their seminal categorization of endoleak, a major complication of endovascular aneurysm repair. In addition to type I (related to the graft device itself) and type II (retrograde flow from collateral branches) endoleak, they propose two new categories: endoleak due to fabric tears, graft disconnection, or disintegration would be classified type III, and flow through the graft presumed to be associated with graft wall "porosity" would be categorized as type IV endoleak.
Pyogenic liver abscess remains a disease with significant mortality. Image-guided percutaneous drainage is appropriate treatment for single unilocular PLA. Surgical drainage is more likely to be required in patients who have abscess rupture, incomplete percutaneous drainage or who have uncorrected primary pathology.
Converting an endoluminal to an open AAA repair may require modifications to the standard open technique and result in a much higher than generally accepted morbidity and mortality rate. Patients rejected for open repair because of co-morbidities ran the same chance of requiring conversion as those without co-morbidities (15-17%). If conversion was required, however, they stood a 3 in 7 or 43% chance of dying.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
