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.

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.

Despite improved outcomes for open repair of descending thoracic aneurysm (DTA) and thoracoabdominal aortic aneurysm (TAAA), these operations remain challenging in octogenarians. Patients unsuitable for thoracic endovascular aortic repair require open surgery to avoid catastrophic rupture. We analyzed our results for DTA/TAAA repair in these elderly patients. ⋯ In select octogenarians, open repair of DTA/TAAA can be performed with acceptable risk. A simplified surgical approach may provide the best opportunity for a successful outcome.

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.

Multicenter Study Comparative Study
Outcomes from the Gore Global Registry for Endovascular Aortic Treatment in patients undergoing thoracic endovascular aortic repair for type B dissection.
The Global Registry for Endovascular Aortic Treatment (GREAT) is a prospective multicenter registry collecting real-world data on the performance of W. L. Gore (Flagstaff, Ariz) aortic endografts. The purpose of the present study was to analyze the implementation and outcomes of thoracic endovascular aortic repair (TEVAR) in GREAT patients with type B aortic dissection (TBAD). ⋯ TEVAR for TBAD using the conformable GORE TAG thoracic endoprosthesis device can be performed with a low incidence of aortic mortality and complications. Acute uncomplicated TBAD patients had a significantly lower mortality rate than that of other patients. Larger proximal landing zones were associated with more frequent retrograde type A dissection. LSA involvement (coverage and/or revascularization) was associated with an increased risk of AEs during follow-up.
