Clinical Trial
Early report from an investigator-initiated investigational device exemption clinical trial on physician-modified endovascular grafts.
To determine whether a physician-modified endovascular graft (PMEG) is a safe and effective method for treating patients with juxtarenal aortic aneurysms who are deemed unsuitable for open repair. ⋯ These preliminary data suggest that endovascular repair with PMEG is safe and effective for managing patients with juxtarenal aortic aneurysms. Endovascular repair with PMEG has acceptable early rates of morbidity, mortality, and endoleak. This endovascular aortic strategy is particularly appealing for those patients presenting with symptomatic or ruptured aortic aneurysms until reliable off-the-shelf solutions become widely available.

Randomized Controlled Trial Multicenter Study Comparative Study
Economic analysis of endovascular repair versus surveillance for patients with small abdominal aortic aneurysms.
The Positive Impact of EndoVascular Options for Treating Aneurysms Early (PIVOTAL) trial enrolled individuals with small (4.0- to 5.0-cm diameter) abdominal aortic aneurysms (AAA) and reported no difference in rupture or aneurysm-related death for patients who received early endovascular repair (EVAR) vs surveillance with serial imaging studies. We evaluated resource use, medical cost, and quality of life outcomes associated with the PIVOTAL treatment strategies. ⋯ A treatment strategy involving early repair of smaller AAA with EVAR is associated with no difference in total medical costs at 48 months vs surveillance with serial imaging studies. Longer follow-up is required to determine whether the late medical cost increases observed for surveillance will persist beyond 48 months.

This study was conducted to provide insight into the safety, applicability, and outcomes of thoracic endovascular aortic repair (TEVAR) with the chimney graft technique. ⋯ TEVAR with the chimney technique is a viable treatment option and may expand treatment strategies for patients with challenging thoracic aortic pathology and anatomy in the emergent and elective setting. Patency of the thoracic chimney stents appears to be good during short-term follow-up. Other complications, such as endoleak and stroke, deserve attention by future research to further improve treatment strategies and the prognosis of these patients.

This study reviewed the natural history of blunt thoracic aortic trauma (BTAT) over a 14-year period at our level 1 trauma center and compared open vs endovascular treatment. ⋯ The incidence of BTAT is low but the mortality associated with it is significant. During the 14-year period studied, there was a clear change in management preference from open repair to endovascular repair at our level 1 trauma center. Outcomes, including stroke, MI, renal failure, paralysis, length of stay, and death, appear to be reduced in the endovascular group.

There is mounting evidence supporting the benefit of surgical skills training in a simulated environment. However, the use of simulation in vascular surgery has been limited, and its value has been poorly understood. Access to simulation is presumed to be a major barrier to its widespread implementation. While a great deal of discussion is taking place at the national level, input from current trainees has not been obtained. ⋯ Trainees report limited operative experience and confidence, and confidence levels are improved for a number of index procedures among those trainees with access to simulation. Trainees endorse the use of simulation to augment their surgical training, and a significant proportion of them already have access to it. These data support a perceived need and utility for implementation of a standardized simulation curriculum in vascular surgical training.
