RESUMEN

Traumatic injuries to the mesenteric vessels are rare and often lethal. Visceral vessels, such as the superior mesenteric artery (SMA) and vein (SMV), supply blood to the small and large bowel by a rich system of collaterals. Because fewer than 100 such injuries have been described in the literature, they pose challenges in both diagnosis and management and can unfortunately result in high mortality rates. Prompt diagnosis, surgical intervention, and resuscitation can lead to improved outcomes. Here, we review the literature surrounding traumatic injuries of the SMA/SMV and discuss management strategies.

RESUMEN

Mass casualty events (MCE) are an infrequent occurrence to most daily healthcare systems however these incidents are the causation for new hospital preparedness and the development of coordinated emergency services. The broad support and operational plans outside the hospital include emergency medical services, local law enforcement, government agencies, and city officials. Modern-day hospital disaster preparedness goals include scheduled training for healthcare personnel to ensure effective and accurate triage for a high-volume of injured patients. This MDT collaboration strengthens the emergency response to optimize the delivery of life-saving care during MCEs. This review identifies the clinical importance of the interdisciplinary team interactions and the lessons learned from past MCE experiences, strengthening healthcare system readiness for such critical incidents.

RESUMEN

BACKGROUND: Elderly patients with aortic stenosis presenting for an aortic valve replacement with a hostile ascending aorta remain a challenging patient cohort. The purpose of this study was to assess outcomes after the use of an aortic valve bypass performed without cardiopulmonary bypass. METHODS: A retrospective review was performed on 21 high-risk patients who underwent primary, isolated aortic valve bypass from September 2004 to June 2009 at Emory Healthcare Hospitals. Aortic valve bypass was used for a porcelain aorta alone in 6 (28.6%) patients, previous coronary artery bypass grafting in 4 (19.0%), or both in 10 (47.6%). One patient (4.8%) was thought not to be a candidate for cardiopulmonary bypass secondary to a severe cirrhosis. RESULTS: Mean age was 73.9±7.0 years (median, 75.0 years), and 15 patients (71.4%) were male. Mean New York Heart Association classification was 3.0±1.0 (median, 3.0), and preoperative ejection fraction was 0.460±0.163 (median, 0.500). Preoperative comorbidities included peripheral vascular disease (n=10; 47.6%), chronic lung disease (n=16; 76.2%), diabetes mellitus (n=10; 47.6%), and dialysis-dependence (n=2; 9.5%). Either an 18-mm (n=11; 52.4%) or 20-mm (n=10; 47.6%) conduit was used, with an interposed Freestyle 21 porcine root in all patients. All operations were performed without cardiopulmonary bypass. There were no intraoperative mortalities. The mean intensive care unit stay was 133.7±161.3 hours (median, 80.2 hours), and overall postoperative length of stay was 12.9±10.8 days (median, 9.0 days). In-hospital mortality occurred in 3 patients (14.3%). Mid-term follow-up shows an additional 4 patients died at a median follow-up of 1.3 years. CONCLUSIONS: Aortic valve bypass without cardiopulmonary bypass is a feasible alternative for the treatment of severe aortic stenosis with acceptable short-term morbidity and minimal mortality in this extremely high-risk surgical population.
