Since the introduction of endovascular technology to treat thoracic and abdominal aortic aneurysms, there has been a global research effort focused on assessing the effectiveness of treatment. A bibliometric analysis is used to identify the scientific impact of an article, impactful authors, institutions, and collaborative groups. Our objective was to identify and to analyze the 100 most cited articles in the field of endovascular treatment of thoracic and abdominal aortic aneurysms. ⋯ This study provides a comprehensive and informative analysis of the most cited and impactful research undertaken in the field of endovascular treatment of abdominal and thoracic aortic aneurysms. By quantitatively assessing the 100 most cited articles in the field, we recognize the contributions of key authors, institutions, and collaborative groups and develop an understanding of the strengths of past research and the requirements for future global efforts.

Randomized Controlled Trial
Patient satisfaction with the consent discussion is not improved by showing patients their computed tomography or angiography images before they undergo vascular surgery.
Patient-based decision aids and other multimedia tools have been developed to help enrich the preoperative discussion between surgeon and patient. Use of these tools, however, can be time-consuming and logistically challenging. We investigated whether simply showing patients their images from preoperative computed tomography (CT) or angiography would improve patients' satisfaction with the preoperative discussion. We also examined whether this improved the patient's understanding and trust and whether it contributed to increased preoperative anxiety. ⋯ Showing patients their CT or angiography images during the preoperative discussion does not improve the patient's satisfaction with the consent discussion. Similarly, there was no effect on the patient's trust, understanding, or anxiety level. Our conclusions are limited by the lack of a standardized measure of patient understanding and not measuring outcomes postoperatively, both of which should be considered in future studies.

Previous studies have reported increased perioperative mortality of nonruptured symptomatic abdominal aortic aneurysms (Sx-AAA) compared with asymptomatic elective AAA (E-AAA) repairs, but no long-term-outcomes have been reported. We sought to compare long-term outcomes of Sx-AAA and E-AAA after repair at a single academic institution. ⋯ Patients with Sx-AAA had lower long-term survival and similar aneurysm-related reinterventions compared with patients with E-AAA undergoing repair. Women also underwent repair for Sx-AAA at a significantly smaller size when compared with men, which emphasizes the role of gender in AAA symptomatology. Differences in long-term survival may be only partially explained by measured patient, aneurysm, and operative factors, and may reflect unmeasured social factors or suggest inherent differences in pathophysiology of Sx-AAAs.

Risk factors for postoperative cognitive decline after noncardiac surgery are multifactorial and poorly understood. Evidence suggests that perioperative microembolic damage to the brain on movement of wires and catheters during endovascular aortic procedures may play an important role. Endovascular aortic aneurysm repair requires invasive manipulation of wires and cannulas within the aorta, but research into cerebral emboli during aortic aneurysm repair and cognitive or neurologic injury is scarce and limited to thoracic aneurysms. This study prospectively studied embolic phenomena detected in the middle cerebral artery during infrarenal, juxtarenal, and thoracic endovascular aortic repair (TEVAR) and investigated links to delirium, stroke, and postoperative cognitive decline. ⋯ Patients are at risk of cerebral emboli during several types of endovascular aortic surgery, although TEVAR remains the highest risk procedure. As yet, there are no validated protective measures available to prevent cerebral emboli and their associated risks of clinical and subclinical neurologic injury.

Fenestrated endovascular aneurysm repair (FEVAR) has been used successfully to treat patients with juxtarenal abdominal aortic aneurysms (JAAAs). Barriers to wide adoption of FEVAR include complexity in planning of fenestration locations on endografts. The purpose of this study was to validate the use of automated planning software to design fenestrated endografts and to treat patients with complex abdominal aortic aneurysms. ⋯ This automated FEVAR planning software accurately and efficiently identifies fenestration locations for vital branch arteries, thus simplifying the planning process and facilitating the FEVAR procedure. Validated automated FEVAR planning could help bring this beneficial therapy to most patients harboring JAAAs.
