Brachial access is a reliable and effective option for treatment of peripheral vascular disease and should be considered when femoral access is difficult or contraindicated and when a bypass graft is present in the femoral region. In addition, bilateral lesions may be approached easily through one brachial artery access site, making this approach advantageous when bilateral lesions are expected. The complication rate is similar to femoral access and can be minimized with ultrasound-guided access distally over the humerus, micropuncture access, and a dedicated postprocedure "hold team."
Pediatric abdominal aortic aneurysms (AAAs) are rarely encountered in clinical practice. The combination of a pediatric AAA in a patient with multiple peripheral artery aneurysms is even more rare. We report the management of an 11-year-old boy who presented with a ruptured AAA who also had multiple peripheral arterial aneurysms. Infectious, genetic, and inflammatory workup was negative, classifying this aneurysm as congenital.
Renal artery aneurysms (RAAs) and renal arteriovenous fistulas (RAVFs) are rare lesions occurring in less than 1% of the population. Understanding treatment options is important in the care of these patients. Depending on the type of disease process, endovascular techniques, vascular bypass, renal autotransplantation, or nephrectomy may be indicated. The case reported describes a combined RRA and RAVF treated with nephrectomy.
Lower extremity arterial injuries (LEAIs) can be complicated injuries resulting in limb loss and death. Patients with LEAI often have multiple injuries increasing the risk for morbidity and mortality. We sought to evaluate the incidence and management of LEAI and to define associations between injuries and outcomes. We performed a retrospective review of LEAI at an urban level-1 trauma center from April 2005 to April 2015. Chi-square tests were used to compare independent groups with respect to mortality and amputation. Means were compared between independent groups using two-sample -tests. From April 2005 to April 2015, 208 arterial injuries occurred in 163 patients. The majority (80.4%) suffered concomitant lower extremity injuries with 35.6% suffering systemic injuries. Surgical intervention was required for 72.1% of injuries. Amputation rate was 14.7%. Mortality rate was 8.0%. Data from 2010 to 2015 were more specifically analyzed. Injury severity score (ISS) was higher with fatalities (37 ± 13.16 vs. 11.8 ± 8.51, < 0.0001) and in patients requiring an amputation (25.4 ± 15.32 compared with 11.6 ± 9.05, = 0.0015). Popliteal artery injury was most likely to require an amputation (odds ratio [OR] = 2.9, = 0.04). Mortality was more likely when systemic injuries were present (OR = 18.1, = 0.0005). The majority of patients with arterial injuries require surgical management, most often with open surgical techniques. Arterial injuries associated with systemic injuries, blunt injury mechanisms, and higher ISS are at a significantly increased risk of mortality.
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.
