Registries have been proven useful to assess clinical outcomes, but data entry and personnel expenses are challenging. We developed a registry to track patients undergoing endovascular aortic aneurysm repair (EVAR) in an integrated health care system, leveraging an electronic medical record (EMR) to evaluate clinical practices, device performance, surgical complications, and medium-term outcomes. This study describes the registry design, data collection, outcomes validation, and ongoing surveillance, highlighting the unique integration with the EMR. ⋯ Leveraging an EMR provides a robust platform for monitoring short-term and midterm outcomes after abdominal aortic aneurysm repair. Use of standardized templates in the EMR allows data entry as part of normal workflow, improving compliance, accuracy, and data capture using limited but expert personnel. Assessment of patient demographics, device performance, practice variation, and postoperative outcomes benefits clinical decision-making by providing complete and adjudicated event reporting. The findings from this large, community-based EVAR registry augment other studies limited to perioperative and short-term outcomes or small patient cohorts.

Comparative Study
Epidemiology of ruptured abdominal aortic aneurysms in a well-defined Norwegian population with trends in incidence, intervention rate, and mortality.
Ruptured infrarenal abdominal aortic aneurysms (rAAAs) represent both a life-threatening emergency for the affected patient and a considerable health burden globally. The aim of this study was to investigate the contemporary epidemiology of rAAA in a defined Norwegian population for which both hospital and autopsy data were available. ⋯ We found a stable incidence and mortality rate during a decade. The prehospital death rate was lower (9%), the intervention rate (73%) higher, and the total mortality (68%) lower than in most other studies. Geographic and regional differences may influence the epidemiologic description of rAAA and hence should be taken into consideration in comparing outcomes for in-hospital mortality and intervention rates.

Although medical management of acute uncomplicated type B aortic dissection remains the standard of care, contemporary data regarding the natural history of medically treated patients are sparse. The goal of this study was to evaluate the natural history of patients with acute type B aortic dissection who were initially managed with medical therapy alone. ⋯ The majority of patients with acute type B dissection will fail medical therapy over time as evidenced by a 6-year intervention-free survival of 41%. Patients who underwent any aortic intervention had a significant survival advantage over those who were treated with medical management alone. Further study is necessary to determine who will benefit most from early intervention.

Combined vascular reconstruction and free flap transfer has been established in centers as a feasible therapeutic option in cases with critical limb ischemia (CLI) and large tissue defects otherwise destined for major amputation. However, the number of patients treated with this combined approach is limited, and data regarding long-term follow-up and functional outcome are scarce. We therefore report our 10-year experience in free flap transplantation after vascular reconstruction as a last attempt for limb salvage, with special emphasis of complication rate, limb salvage, and postoperative mobility. ⋯ The combined approach for limb salvage in CLI patients is associated with excellent results in limb salvage and functional outcome in patients who would otherwise be candidates for major amputation, despite an initially elevated complication rate. The option of combined revascularization with free tissue transfer should be evaluated in all mobile patients with CLI, large tissue defects, and exposed tendon or bone structures before major amputation. However, further studies are required to support these results.

Color duplex sonography (CDS) today is broadly used in the diagnostic workup of patients with suspected cranial or extracranial giant cell arteritis (GCA). This study aimed to determine the prognostic impact of the disease pattern assessed by CDS on the treatment response in GCA. ⋯ Extensive vascular involvement of both the temporal and subclavian/axillary arteries, as depicted by CDS, may be associated with a poor treatment response in GCA.
