The Effects of Weekend Admission on the Outcomes and Management of Ruptured Aortic Aneurysms Objective: Ruptured aortic aneurysm is a condition with a high rate of mortality that requires prompt surgical intervention. It has been noted that in some conditions requiting such prompt intervention, in-hospital mortality is increased in patients admitted on the weekends as compared to patients admitted on weekdays. We sought to determine if this was indeed the case for both ruptured thoracic and abdominal aortic aneurysm and elucidate the possible reasons. Methods: Using the Nationwide Inpatient Sample (NIS), a publicly available database of inpatient care, we analyzed the incidence of mortality among patients admitted on the weekends compared to weekdays for ruptured aortic aneurysm. Ultimately the care of over 7,000 patients was analyzed for the primary endpoints. We adjusted for demographics, comorbid conditions, hospital characteristics, rates of surgical intervention, timing of surgical intervention and use of additional therapeutic measures. Results: Patients admitted on the weekend for both ruptured thoracic and abdominal aortic aneurysm had a statistically significant increase in mortality as compared to those admitted on the weekdays (OR 2.55 for Thoracic and 1.32 for Abdominal). By our analysis this is likely due to a delay in surgical care on the weekends. Conclusions: Weekend admission for ruptured aortic aneurysm is associated with an increased mortality when compared to those admitted on the weekend and this is likely due to several factors with the most predominant being a delay in surgical intervention.

This is a case report of a femoral artery infection with fatal outcome after using a percutaneous suture mediated closure device: A 77-year old patient underwent diagnostic angiography of his thoracic and abdominal aortic aneurysm, the puncture site was closed with the Perclose® system. He developed a staphylococcal femoral artery infection with groin abscess, requiring surgical intervention with debridement and removal of the Perclose® suture. After stent graft exclusion of the thoracic and abdominal aortic aneurysm a staphylococcal sepsis occurred and the patient died of aneurysm rupture months later despite long term antibiotic therapy. Since the use of the Perclose® device carries an increased risk of femoral artery infection with septic endarteritis and bacteremia, it should not be used in routine diagnostic angiography.

Introduction Endoluminal stent grafts are replacing conventional abdominal aortic aneurysm (AAA) surgery in an increasing number of patients in an attempt to minimize morbidity and mortality. Long-term follow-up of endograft-treated AAA demands image-based surveillance to detect endoleak, graft migration, and morphology change in the excluded AAA. AAA diameter is a traditional but simplistic measurement that has inherent flaws and has been shown to be insensitive to changes in AAA sac morphology. Volume measurement, performed by CT data acquisition and computerized postprocessing, has been proposed as the most sensitive index of successful AAA stent graft exclusion. We evaluated two ultrasound (US) volume measuring techniques for AAA volume determination: Virtual Organ Computer-aided AnaLysis (VOCAL) and Multi-Plane Area Summation (MPAS). Methods US images of an endograft-treated AAA were obtained with a commercially available three-dimensional (3-D) scanner. A fast rotating motor inside the probe allowed registration of multiple two-dimensional (2-D) images in real time. Data from these images were assembled in a 3-D dataset. With VOCAL, the 3-D AAA boundaries were identified, and volume was calculated. The operator traced AAA boundaries in six virtual planes selected by the software. With MPAS, aneurysm boundaries were traced in 2-D virtual images perpendicular to the longitudinal axis of the aneurysm obtained every 1 mm. AAA area was calculated and multiplied by this 1-mm step to obtain incremental volumes that were summed to obtain the AAA volume. VOCAL and MPAS volumes were calculated 10 times each for one AAA scan. Results Average AAA volumes were 86.7 ± 3.7 cm3 with VOCAL and 87.6 ± 3.1 cm3 with MPAS. These averages were not statistically significantly different by t test ( p = 0.54). Standard deviation (SD) to average ratio was 4.3% for VOCAL and 3.5% for MPAS. Conclusion Volume of an endograft-treated AAA was successfully measured multiple times with two 3-D US techniques. Volumes obtained were comparable, demonstrating feasible reproducibility.
